De-central Layered Manufacturing Phd Research: Ir. Dennis ten Dam Presented by: Dr. Ir. T. Vaneker 6/3/2009 1
Management Concluding Remarks 6/3/2009 2
Advantage: Current supply chain can handle almost all types of milling parts Disadvantage: The supply chain is unnecessary complex for the vast majority of all milled parts (Pareto: 20% of all parts cause 80% of all problems) Excessive throughput times, communication needs & costs if generic standardized processes are used for the manufacturing of non-complex parts 6/3/2009 3
Calculation & Process Planning NC-Programming Production Inspection OEM: Purchasing Purchasing Sales Defined to be able to handle parts of all levels of complexity From the point of view of different levels of complexity the supply chain suffers from Island automation\lack of integration (To ) many communications links & inefficient communication To complex level of order processing Redundant engineering Inflexible: tough adjustment of request and capacity Inefficient production processes Long lead times Expedition 6/3/2009 4
Common milling parts: Small products of limited complexity Shoebox sized products Prismatic shapes Standardized manufacturing Materials Machines Tooling sets No re-engineering or product optimization Produced as received Small and medium batches Often variants of well known products 6/3/2009 5
research goals If parts can be identified as common can the supply chain be optimized by automation and/or integration of supply chain steps to a level that benefits all involved in the supply chain. Or in more detail Will this for the customer among others result in a shortened time between design and production and lower manufacturing costs. Can CNC worknet become a unique manufacturing concept, if it focuses on a very distinct section of the market. Can it for example be up scaled to a national or international networks of franchised production plants 6/3/2009 6
Calculation & Process Planning NC-Programming Production OEM: Purchasing Purchasing Sales Automate fully - Consumer interaction via internet portal Maximize level of automation -for non complex products these means are, to a large extend, already available - Manage all data exchange between them Externalize - Part size allows for standard (TNT) delivery Inspection Expedition 6/3/2009 7
focus -Reduce the complexity of the supply chain -Speed up the quotation process -Automate process planning -Reduce delivery time -Reduce cost -Reduce logistic consequences 6/3/2009 8

Concept Factory Ede (NL) Concept factory is already producing parts for our customers Partners & Suppliers: system 3R 2x DMU 70 evolinear 1x Matsuura 72-63V Robotics Mach-V CMM Tooling sets 6/3/2009 17
Applications: Sales Process Planning Purchasing Logistics Quality Management Manufacturing Business Administration Franchise & Marketing Information Management Applications (sales, PP etc) are organized in functional disks. Information management theories are used to exchange information between 6/3/2009 (components of the) functional disks and a central information database 18
Functional modules: Independent Flexible Modular Information retrieval and storage through Information Management kernel Allowing stepwise automation 6/3/2009 19
