5 Select a Control System CNCtrain simulates several CNC control types. To select the control that you would like to simulate click on the 'Control Type' menu at the top of the screen and choose any of the active listed controls. CNCtrain will remember the last control that was selected when the software is re-run. The above example shows the Fanuc0M Milling control has been selected. p5

6 Setting the Best Screen Layout CNCtrain allows you to customise the layout of the screen to suit your own system. This can be helpful when using different screen resolutions or when the CNC lines are long. You can choose to have the CNC editor to the left of the screen or at the bottom of the screen. To adjust the size of the CNC editor in relation to the simulation screen either click on and drag the vertical or horizontal red line to resize. Any new layout will be stored and reloaded when CNCtrain is re-run. p6

7 Loading Cnc Files Select Load Cnc program from the 'File' menu. All CNC Files are stored in a seperate folder. For example Fanuc0M milling files are stored in Cncfiles\Fanuc0M folder. It is important not to mix different types of CNC programs in a single folder. Use the default directories or create your own student directories if required. Select from the list of CNC programs. p7

8 editor. Your CNC program will be loaded into the All material type, billet size, tool offsets and tool library are stored with each CNC program and these parameters will be loaded when load a new CNC program. After loading an example, check the billet settings and the tool library to see the changes. p8

9 Simulation Modes Use the four Simulation modes from the toolbar at anytime during or before the simulation. Selects 3d Simulation. In 3d mode you can rotate the billet. Selects Plan View only. Selects Toolpath, try selecting toolpath simulation after 3D or Plan View simulation to superimpose the toolpath over the machined surface. Selects Side View. Shows the spindle on and off with vertical axis movement. p9

11 Running the Simulation Press the Cycle Start button to begin a new simulation, to re-start the simulation after a program stop and to re-start the simulation when 'single step' or 'step by step' is active. Press the Cycle Stop button to cancel program execution. Press the Pause Button to pause the simulation. Press the Pause button to re-start the simulation. each line. use the single block and step by step options to simulate a cycle or step through Use the speed bar to control the speed of the simulation. Axis positions, feed, speed and tool numbers are displayed during the simulation. A machining time is also shown. Try zooming in or out of the simulation before simulating the CNC program. This will always redraw the billet in full, even if you select this option during simulation. If you zoom in too much the simulation may well slow down. Use the 'Part Zoom' to see more detail. In Plan View or Side View resize the rectangle using the bottom end corner of the red square and then drag the rectangle after clicking inside. Once the rectangle is the correct size and position, check the 'part Zoom' box. A new billet will be drawn. Select 'Cycle Start' to simulate then part section. p11

13 CNCteach Interactive Lessons CNCteach is ideal for the beginner. Example programs covering all the cycles and moves of the CNC control can be selected and simulated with descriptive comments guiding the student through the machining process. Press the of the screen. button to select. Select an example from the pull down menus at the top Select a group from the left hand menu at the top of the screen. the screen. Select an example from the list at the right hand menu at the top of The example will be displayed in the CNC editor. press Cycle Start to continue. During the CNC lesson you can interact with the simulation using the tool bar menu. To return to Off Line programming mode click on the button. p13

15 Setting Billet Size Click on the 'Select Material' button to activate the Material Library. Select a material and enter the billet sizes. If the datum is at the bottom left hand corner of the billet and at the top surface of billet then leave the billet Shift values at Zero, otherwise enter the shift values. p15

16 Create Tooling Library Click on the 'Select Tooling' button to crete a library of tools. column. Tool library is listed in the left hand To change the tool type or the diameter select the type of tool from the right hand list. Click on the button. Enter the tool number followed by the cutter diameter. The new tool will be updated in the left hand column. p16

17 Enter a New CNC Program To start a new CNC program select 'New CNC Program' from the File menu. If the current program has changed and not been saved, follow the prompts to save or overwrite an existing program Y/N?. Once the CNC editor is empty you can start to enter a new CNC program. Make sure you are in edit mode. A full list of the G and M codes is available from the pull down menus. Select a group from the left hand menu at the top of the screen. the screen. Select from the list of codes from the right hand menu at the top of Clikc on the help button to display the help window. Remember to use capital letters for all letter prefixes. Comments can be added to the CNC program using the relevant character. Example Fanuc : G00 X23.3 Y23.5 (Linear move along the X and Y axis at maximum feed. You can Cycle Start and run the CNC part program at anytime. However if you are using subroutines or loops make sure they are complete before simulating. After pressing Cycle start from Edit Mode the system will automatically select Auto Mode and start the simulation. Following completion of the simulation you will need to select edit Mode to continue adding lines to your CNC part program. p17

18 CNCwrite programming Wizard CNCwrite is a powerful programming wizard that is available at anytime. You must select CNCwrite to enter any CNC part program. Select a command from the pull down menus. Click on Enter data if the code starts on a new line and append data to add to the current line. Make sure the cursor is at the end of the previous line before selecting You will prompted to enter all the parameters and the CNC code will be placed in the CNC editor automatically for you. Click on the 'enter data' button for each part of the CNC line. p18
