KENNA PERFECT Inserts Cast Iron Tool Tips: Wiper Inserts Wiper inserts are an excellent choice for straight OD, ID, and facing cuts. Feed rates can be doubled, reducing machining time by 50% while maintaining the surface finish. Insert nose radius has no effect on finish since the wiper radius generates the final finish. Wiper inserts typically last longer since the work is spread over a longer cutting edge. Grade KC9315 Grade KC9315 is the first choice for machining ductile irons. The thick medium-temperature CVD TiCN layer combats flank wear, which is the usual failure mechanism when machining ductile irons with a tensile strength of 50 ksi and greater. Use geometries..ma, MG-UN, and MG-RP. Grade KC9325 Grade KC9325 is ideally suited for machining gray irons and low-strength ductile irons (<45 ksi). Crater wear is the primary wear mechanism when machining gray irons at high speeds. Grade KC9325 combats crater wear with a very thick Al 2 O 3 layer. The grade s unique combination of toughness and speed capability make it a first choice for gray iron machining up to 1300 sfm. MG-RP Geometry The -RP geometry is available in a wide variety of grades and can be used to reduce cutting forces on unstable cuts or where work holding is not optimal. This is particularly advantageous when machining high-strength ductile irons ( 80 ksi). Reduced forces lower the temperature at the cutting interface, providing long, predictable tool life. Grade KC9110 Grade KC9110 is an excellent choice for interrupted cutting conditions where grades KC9315 and KC9325 are not tough enough. Its unique combination of speed capability and outstanding toughness makes it an excellent choice for heavily interrupted cuts. Use MG-RN geometry as a first choice. 18
KENNA PERFECT Inserts Cast Iron Tool Tips: Grade KY3500 Kyon 3500 is your first-choice ceramic cutting tool for tough gray cast iron applications, especially those with interruptions and scale. KY3500 is the most dependable ceramic grade for harsh gray cast iron applications, and can be run wet or dry. Grade KY1310 (available January 2004) Kyon 1310 is designed specifically to maximize tool life in dry, continuous gray cast iron applications. Although not as tough as KY3500, KY1310 possesses good toughness at a high hardness level to optimize abrasive wear properties. Use KY1310 for continuous cutting in tandem with KY3500 for more severe gray cast iron cutting applications to maximize tool life and minimize costs. Top Notch Turning System for Ceramics When cutting with ceramics at high speeds, it is important to maximize the rigidity of the insert and toolholder. The Top Notch tooling system used in tandem with grades KY3500, KY1310, and KY3400 dimple inserts provides ultimate rigidity for cast iron applications. Insert Failure Analysis Check the insert thoroughly for signs of failure. To optimize your metalcutting process, remove inserts from the toolholder and inspect regularly for wear. Signs of chipping, deformation, built-up edge, cratering, flank wear, and thermal cracking are very evident in the early stages of wear but are almost impossible to detect after total insert failure. Boring with Wiper Inserts When boring with wiper inserts, chatter may increase due to the large wiper radii. To offset this lateral tool pressure, decrease the nose radius and increase the depth of cut. Remember that the nose radius of a wiper insert doesn t affect surface finish. 19
New Cutting Tool Technologies Grade KC9315 During the last 20 years, dramatic improvements have been made in turning insert performance through the development of innovative coating materials such as aluminum oxide (Al 2 O 3 ) and medium-temperature titanium carbonitride (MT-TiCN). In recent years, cutting tool materials have advanced even further through improvements in coating interface adhesion, which can provide thicker and more complex coating layers. This innovative processing produces smoother, less reactive coating surfaces that resist edge build up, microchipping, and chip hammering. Coating Systems The thickness and of layers of coatings on an insert typically have been limited to ensure the integrity and stability of the coating. A coating thickness of 10 to 14 microns typically was the limit, which is significantly less than the optimum value. New technologies now make it possible to increase both the and thickness of the layers by providing high-strength interface transition zones that increase the adhesion between the coatings. We employ this new technology on our new 18-micron coating system for grade KC9315. In conjunction with a hard deformation-resistant substrate, KC9315 is designed especially for high-performance machining of ductile irons and high-strength steels. This new coating consists of three main layers. The bottom layer is titanium carbonitride to protect against flank wear a major failure mechanism in ductile iron and steel turning. This layer is applied in a medium-temperature chemical vapor deposition coating process that reduces the mismatch in thermal contraction rates during cooling to provide fewer coating cracks and a tougher cutting edge. The middle layer is fine-grained alpha crystal structure alumina that protects against the elevated temperatures encountered in high-speed cutting and provides an abrasion-resistant, chemically inert TiN/TiCN }18 µm Al 2 O 3 total (alpha crystal structure) K-MTCVD TiCN Micro-finished edge barrier. The alpha crystal structure is more stable than the more common kappa structure and improves the coating resistance to failure. The top layer is a 2-micron titanium nitride/titanium carbonitride layer that provides additional wear resistance and serves as a wear indicator. Grade KC9315 has an improved post-coating surface treatment that contributes to increased tool performance. Polishing the outer coating surface to a higher-than-normal degree minimizes the potential for built-up edge. In particular, the surface treatment removes the outer TiN / TiCN coating from the tool-chip interface zone to further reduce the possibility of built-up edge. The net advantage is the ability to run at higher speeds and feeds relative to existing coated materials without suffering a reduction in tool life. KC9315 is an excellent performer at finishing to medium machining at the elevated speeds required to be competitive when machining cast iron. 20

New Cutting Tool Technologies Silicon Nitride Ceramics for Gray Cast Iron Silicon nitride-based ceramics are the predominant ceramic tools used for cast iron machining, particularly gray cast irons. These tools excel in cast iron applications because of a unique combination hardness, fracture toughness, and thermal conductivity. High hardness maintained at elevated temperatures (see figure 1) is key to the high-speed application of these tools and gives dramatic performance advantages over coated carbide tools. The combination of high hardness, good thermal conductivity, and high fracture toughness results in a very consistent, reliable tool that excels in demanding cast iron applications. In the 1980s and early 1990s, hot pressed silicon nitride ceramics were used in very few gray cast iron machining applications. The introduction of Kennametal s Kyon 3500 in 1993 changed that. Using breakthrough technology, KY3500 was produced using basic powder metallurgy methods and eliminated the need for onerous hot pressing. Today, Kyon 3500 remains the industry standard as the most dependable commercial ceramic grade on the market. KY3500 differentiates itself from the competition in difficult applications that involve aggressive conditions and interrupted cutting. Kyon 1310 continues the legacy of Kennametal breakthrough ceramic products. Through state-ofthe-art material development and processing, the wear resistance of KY1310 is greatly enhanced. KY1310 targets continuous turning of gray cast iron to provide superior wear resistance. It is ideal for automotive and truck brake disk and rotor applications. Proven Superiority Recently, we tested KY3500 and KY1310 against an incumbent competitor silicon nitride grade in a customer s continuous turning application on gray cast iron automotive valve rings.

Metallurgy and Machinability Metallurgy Overview Cast irons are iron-carbon-silicon alloys containing large amounts of carbon either as graphite or as iron carbide. They have higher carbon (>1.7%) and silicon (1.0-3.5%) contents than steel. Silicon promotes dissociation of iron carbide to iron and graphite. By increasing the silicon content in cast iron, a greater proportion of graphite can be obtained at the expense of combined carbon. The microstructure and mechanical properties of cast irons can be controlled not only by chemical composition but also by cooling rate. Increasing the cooling rate will refine the graphite size as well as the matrix structure and will increase strength and hardness. It also may increase the chilling tendency, which may increase the hardness but decrease the strength. Alloys within the broad group of cast irons include white iron, gray cast iron, mottled cast iron, malleable cast iron, and ductile cast iron. Each of these alloys may be modified by alloy additions to obtain specific properties. Below are selected ASTM standards for different classes of cast irons. Selected ASTM Standards for Cast Irons Unalloyed Cast Irons A47 Malleable iron castings A48 Gray iron castings A126 Gray iron castings for valves, flanges, and pipe fittings A159 Automotive gray iron castings A197 Cupola malleable iron A220 Pearlitic malleable iron castings A278 Gray iron castings for pressure-containment with temperatures up to 345 C (650 F) A319 Gray iron castings for elevated temperatures non-pressure containing parts A395 Ferritic ductile iron pressure-retaining castings for elevated temperatures A476 Ductile iron castings for papermill dryer rolls A536 Ductile iron castings A602 Automotive malleable iron castings Low and Moderate Alloyed Cast Irons A319 A874 Gray iron castins for elevated temperatures for non-pressure containing parts Ferritic ductile iron castings for low-temperature service parts High-Silicon Cast Irons A532 Abrasion-resistant cast irons High-Nickel Austenitic Cast Irons A436 Austenitic gray iron castings A439 Austenitic ductile iron castings 571 Austenitic ductile iron castings for pressurecontaining parts for low-temperature service 32 Machinability Overview Machinability refers to the ease with which a workpiece can be machined and measured in terms of tool life, metal removal rates, surface finish, ease of chip formation, or cutting forces. It is not an intrinsic property of a material, but is a result of complex interactions between the mechanical properties of the workpiece, cutting tools, lubricants used, and machining conditions. Cast iron machinability varies greatly depending on the type of iron and its microstructure. Ferritic cast irons are easiest to machine, while white irons are extremely difficult to machine. Other grades of cast iron, such as malleable, ductile, compacted graphite, and alloyed cast irons, are in between ferritic and white irons in ease of machinability. Additionally, hard spots in castings formed during rapid cooling and in presence of excessive levels of carbide forming elements can seriously degrade machinability. Alloy cast irons (ASTM A532, A518) can be classified as white cast irons, corrosion-resistant irons, and heat-resistant irons. Generally, they are based on the iron (Fe) - carbon (C) - silicon (Si) system and contain one or more alloying elements that are added (>3%) to enhance one or more useful properties (corrosion resistance or strength or oxidation resistance at elevated temperatures). Small amounts of ferrosilicon, cerium, or magnesium that are added to control the size, shape, and distribution of graphite particles are called inoculants, rather than alloying elements. Inoculation does not change the basic composition or alter the properties of the constituents in the microstructure. The alloyed irons for corrosion resistance are either 13-36% nickel (Ni) gray and ductile irons (also called Ni-resist irons) or high silicon (~14.5% Si) gray irons. For elevated temperature service, nickel (Ni), silicon (Si), or aluminum (Al) alloyed gray and ductile irons are employed. Figure 1: Microstructure of white cast iron
Metallurgy and Machinability White cast irons, also known as abrasion-resistant cast irons, are an iron-carbon alloy in which the carbon content exceeds 1.7%. White cast iron does not have any graphite in the microstructure. Instead, the carbon is present either as ironcarbide or complex iron-chromium carbides (Figure 1), which are responsible for high hardness and resistance to abrasive wear. White iron shows a white, crystalline fracture surface because fracture occurs along the carbide plates. White iron can be produced either throughout the section or only on the surface by casting the molten metal against graphite or metal chill. In the latter case, it is referred to as chilled iron. Corrosion-resistant cast irons obtain their resistance to chemical wear primarily from their high alloy content of silicon, chromium, or nickel. Depending on which of the three alloys dominates the compositions, the corrosion-resistant material can be ferritic, pearlitic, martensitic, or austenitic. Machinability Alloy Cast Irons White irons and corrosion-resistant high-silicon (14.5%Si) gray irons are the most difficult cast irons to machine. Alloyed white irons such as nickel-hard (Ni-hard) alloys and high-silicon irons (ASTM A518) are generally ground to size or turned with a polycrystalline cubic boron nitride (PCBN) tool material such as Kennametal grades KB9640, KD120, or KB5625 Gray cast irons (ASTM A48, A126, A159, ASME AS278 and SAE J431) are named such because their fracture has a gray appearance and consists of graphite flakes embedded in a matrix of ferrite or pearlite, or a mixture of the two depending on the composition and cooling rate (Figures 2a-2d). Ferrite is a soft, low-carbon alpha iron phase with low tensile strength but high ductility. Pearlite consists of lamellar plates of soft ferrite and hard cementite. Gray irons contain 2.5 to 4% carbon (C), 1-3% silicon (Si), and manganese (Mn) (~0.1% Mn in ferritic gray irons and as high as 1.2% Mn in pearlitic gray irons). Sulfur (S) and phosphorus (P) may be present as residual impurities. Manganese is deliberately added to neutralize the sulfur. The resulting manganese sulfide is uniformly distributed in the matrix of gray iron as inclusions. ASTM specification A48 classifies gray cast irons in terms of tensile strength (class 20 with 20 ksi minimum tensile strength to class 60 with 60 ksi minimum tensile strength). The fluidity of liquid gray iron and its expansion during solidification due to the formation of graphite are responsible for the economic production of shrinkage-free, intricate castings such as engine blocks. Most gray iron components are used in the as-cast condition. However, for specific casting requirements, they can be heat treated (annealed, stress relieved, or normalized). Other heat treatments include hardening and tempering, austempering, martempering, and flame or induction hardening. Figure 2a: Type C flake graphite in gray iron Figure 2c: Coarse pearlite in gray cast iron Machinability Gray Cast Irons Figure 2b: Pearlite-ferrite gray cast iron Figure 2d: Pearlitic gray cast iron Most gray cast irons are easier to machine than other cast irons of similar hardness and virtually all steels. This is because the graphite flakes in the microstructure act as chip breakers and serve as a lubricant for the cutting tool. Machining difficulties can still occur in gray iron if chills are present in corners and thin sections or when sand is embedded in the casting surface. The material also shows a tendency to break out during exit from the cut. Although the graphite in cast iron imparts its free-machining characteristics, the matrix surrounding the graphite determines tool life. In fully annealed state, cast irons have a ferritic matrix and exhibit the best machinability. (While not as soft as ferrite in steel, the ferritic cast iron shows better machinability than ferritic steel due to the slight hardening effect of the dissolved silicon and the chip breaking and lubricating effect of the graphite.)

Metallurgy and Machinability and pearlite increases, tool life decreases rapidly. Both iron and alloy carbides, when present as large particles, are detrimental to tool life. Irons with higher phosphorous contents (~0.4%) form a hard constituent called steadite, which has a detrimental effect on tool life. Gray cast irons are productively turned and milled with multi-layered alumina and TiCN coated inserts. The substrate tool material can be either carbide or silicon nitride-based ceramic. Cermet grades such as KT315 are ideal for light depth-ofcut applications. A pure silicon nitride grade such as KY3500 often yields the highest productivity on general turning and milling applications at high speeds. Drilling applications are highly dependent on the drill geometry as well as drill grade. Kennametal solid carbide drills in the TF (triple flute) and SE (sculptured edge) geometries in TiALN-coated grades KC7210 and KC7215 are the most desirable. For indexable insert drilling applications, TiALN-coated KC7725 and alumina coated KC7935 grades are the first choice for high-speed, high productivity applications. Ductile (nodular) irons (ASTM A395, A476, A439, A536 and SAE J434), previously known as nodular iron or spheroidal-graphite cast iron, contain nodules of graphite embedded in a matrix of ferrite or pearlite or both (Figures 3a-3c). The graphite separates as nodules from molten iron during solidification because of additives cerium (Ce) and magnesium (Mg) introduced in the molten iron before casting. The nodules act as crack arresters and impart ductility to the material. By contrast, neither white iron nor gray iron shows a significant amount of ductility. Ductile iron is of higher purity (low phosphorus [P] and sulfur [S]) and is stronger than gray iron. With a high percentage of graphite nodules present in the microstructure, the matrix determines the mechanical properties of ductile iron. Table B compares the composition of ductile iron with that of gray iron and malleable iron. The ASTM classifies different grades of ductile irons in terms of tensile strength in ksi, yield strength in ksi, and elongation in percent. For example, ASTM A536 specifies five standard ductile iron grades: 60-40-18 / 65-45-12 (ferritic ductile iron), 80-55-06 (ferritic-pearlitic ductile iron), 100-70-03 (pearlitic ductile iron), and 120-90-02 (quenched and tempered martensitic ductile iron). Ferritic ductile iron the ferrite matrix provides good ductility and impact resistance and tensile strength equivalent to low-carbon steel. Ferritic ductile iron can be produced as-cast or may be given an annealing treatment to obtain maximum ductility and low-temperature toughness. Ferritic-pearlitic ductile irons usually produced in the as cast condition and feature both ferrite and pearlite in the microstructure. Properties are intermediate between ferritic and pearlitic ductile irons.

Metallurgy and Machinability Pearlitic ductile irons - the pearlitic matrix provides high strength, good wear resistance, and moderate ductility and impact resistance. While the aforementioned three types of ductile iron are most common and used in as-cast condition, ductile irons also can be alloyed and/or heattreated to provide additional grades as follows: Martensitic ductile irons are produced using sufficient alloy additions to prevent pearlite formation, and a quench-and-temper heat treatment to produce a tempered martensitic matrix. These materials have a high strength and wear resistance but lower levels of ductility and toughness. Bainitic ductile irons are produced through alloying and/or by heat treatment to provide a hard, wear-resistant material. Austenitic ductile irons are produced through alloying additions to provide good corrosion and oxidation resistance, magnetic properties, and strength and dimensional stability at high temperatures. Machinability - Ductile Irons The spherical graphite in ductile iron acts similar to the flake graphite in gray iron in chip breaking and lubrication in machining. Machinability increases with silicon content up to 3%, but decreases significantly at higher silicon levels. As in the case of gray cast iron, machinability decreases with increasing pearlite content in the microstructure. Finer pearlite structures also decrease machinability. Still, pearlitic ductile irons are considered to have the best combination of machinability and wear resistance. Cast irons with tempered martensitic structure have a better machinability than pearlite with similar hardness. Other microstructures such as acicular bainite and acicular ferrite formed during heat treatment of ductile irons have machinability similar to martensite tempered to the same hardness. The higher tensile strength of ductile irons compared to gray cast iron requires better rigidity within the machining system. Tool performance life may be slightly lower if run at gray cast iron surface speeds. Ductile cast irons can be productively turned and milled with multi-layered alumina and TiCN or PVD TiALN-coated inserts but at slightly slower speeds than gray cast irons. Malleable cast irons (ASTM A602 and A47) consist of uniformly dispersed and irregularly shaped graphite nodules (often called temper graphite because it is formed by the dissolution of cementite in the solid state) embedded in a matrix of ferrite, pearlite (Figure 4), or tempered martensite. Malleable iron is cast as white iron and then heat-treated to impart ductility to an otherwise brittle material. Malleable iron possesses considerable ductility and toughness due to the nodular graphite and a lower carbon metallic matrix. It has good fatigue strength and damping capacity, good corrosion resistance, good magnetic permeability, and low magnetic retention for magnetic clutches and brakes. Malleable iron, like medium-carbon steel, can be heat treated to obtain different matrix microstructures (ferrite, pearlite, tempered pearlite, bainite, tempered martensite, or a combination of these) and mechanical properties. Malleable and gray irons differ in two respects: the iron carbide is partially or completely dissociated in malleable cast iron; the dissociation occurs only when the alloy is solid. However, the dissociation in gray cast iron occurs during the early stages of solidification; hence the difference in the character of graphite in each material. Figure 4: Coarse pearlite in annealed malleable iron Machinability Malleable Cast Irons The machinability of malleable iron is considered to be better than that of free-cutting steel. Use lowstrength ductile iron machining recommendations. Austempered ductile irons (ADI) (ASTM A897-90) are used as cast, but some castings are heat treated to achieve desired properties. Austempered ductile irons are produced from conventional ductile iron through a special two-stage heat Photomicrographs courtesy of Buehler Ltd., Lake Bluff, Illinois, USA, www.buehler.com 35
Metallurgy and Machinability treatment. The microstructure consists of spheroidal graphite in a matrix of acicular ferrite and stabilized austenite (called ausferrite) (Figure 5). The fine-grained acicular ferrite provides an exceptional combination of high tensile strength with good ductility and toughness. ADI can be given a range of properties through control of austempering conditions. Compared to conventional grades of ductile iron, ADI offers twice the tensile strength for a given level of elongation. Compacted graphite iron (CGI) (ASTM A842) has a microstructure in which the graphite is interconnected like the flake graphite in gray cast iron, but the graphite in CGI is coarser and more rounded (Figure 6). In other words, the structure of CGI is between that of gray and ductile iron. The graphite morphology allows better use of the matrix, yielding higher strength and ductility than gray irons. The interconnected graphite in CGI provides better thermal conductivity and damping capacity than the spheroidal graphite in ductile iron. Although the CGI is less section-sensitive than gray iron, high cooling rates are avoided because of the high propensity of the CGI for chilling and high nodule count in thin sections. Figure 5: Austempered ductile iron Machinability Austempered Ductile Irons The machinability of the softer grades of austempered ductile iron (ADI) is equal or superior to that of steels with equivalent strength. ADI can be machined complete in the soft, as-cast state before heat treatment. This enables faster machine feeds and speeds and significantly increases tool life. As the hardness of ADI increases, tool life decreases substantially. For this reason, only the 125/80/10 and 150/100/7 grades of ADI are machined after austempering. Processing sequence for parts processed to the higher strength: cast the component subcritically anneal to a fully ferritic matrix machine austemper finish machine (if required) finish operations (rolling, grinding, peening, if required) Follow high-strength ductile iron recommendations during machining. Figure 6: Compacted graphite Machinability Compacted Graphite Iron The graphite morphology in compacted graphite iron enables chipbreaking but is strong enough to prevent powdery chip formations. This combination is ideal for good machinability. As a result, the machinability of compacted graphite iron lies between that of gray iron and ductile iron for a given matrix structure. Use low-strength ductile iron machining recommendations. Photomicrographs courtesy of Buehler Ltd., Lake Bluff, Illinois, USA, www.buehler.com 36

Insert Edge Preparation Edge Preparation for Kennametal s Advanced Cutting Tool Materials Edge preparation is the term for the intentional modification of the cutting edge of an indexable insert to enhance its performance in a metalcutting operation. Ceramic cutting tool materials have a much higher hardness, but lower toughness, compared to conventional carbide materials. Because of this, ceramic materials have good bulk strength but lower edge strength versus carbide. To optimize performance of ceramic cutting tools, it is critical that tool material, workpiece material, and machining conditions be considered relative to edge preparation. To achieve optimum edge preparation, make the minimum amount of modification necessary to distribute forces sufficiently enough to prevent chipping and catastrophic insert failure. Edge preparations for standard inserts made with specific ceramic grades are determined by target applications and listed in the KENNA PERFECT insert selection system. There are three choices of edge preparation for ceramic materials: There is a tradeoff to the benefits of this edge preparation. Increasing the width T of the T-land or the angle A increases the overall cutting forces acting on the insert. This can negatively affect the wear rate of the insert and/or deformation of a thin-walled workpiece. For most cast iron turning applications, use a T-land width smaller than the feed rate. For heavily interrupted turning, hard turning (workpiece >50 HRC), and milling applications, use a T-land width larger than the feed rate. 2. Hone Hones protect the insert cutting edge by eliminating the sharp edge and distributing the cutting forces over a larger area. Hones generally are recommended for continuous or finishing operations; however, depending on the workpiece material, they can be used for interrupted or heavy cutting. 1. T-land 2. hone 3. T-land plus hone 1. T-land T lands protect the insert cutting edge by directing forces into the greater part of the insert, rather than to the smaller cross section of the sharp edge, during the metalcutting process. This helps prevent chipping and catastrophic failure. 3. T-land plus hone In aggressive applications, such as interrupted turning, chipping can occur at the intersection of the T-land and flank surface of the ceramic insert. This condition may be eliminated by applying a small hone to the intersection while leaving the other attributes of the T-land unchanged. 49

Application Guidelines Cast Iron Nose Radius Selection and Surface Finish for Conventional Inserts* 1 2 3 4 Nose radius and feed rate have the greatest impact on surface finish. To determine the nose radius required for a theoretical surface finish, use the following procedure and the chart above. 1 Locate the required surface finish (rms or AA) on the vertical axis. 2 Follow the horizontal line corresponding to the desired theoretical finish to where it intersects the diagonal line corresponding to the intended feed rate. 3 Project a line downward to the nose radius scale and read the required nose radius. 4 If this line falls between two values, choose the larger value. If no available nose radius will produce the required finish, feed rate must be reduced. Reverse the procedure to obtain surface finish from a given nose radius. *NOTE: See pages 57-59 for radius and surface finish specifications using wiper-style inserts. NOTE: Peaks produced with a small radii insert (top) compared to those produced with a large radius insert (bottom). 61
