(The Part Geometry is only required if gouge checking is performed.) New => Lataa kappale (aihio) Open => 1

2 2. Create a manufacturing setup and move the MCS to the correct location in reference to the part shape. In the MCS specify a Fixture Offset number of 1 to be used for G54 output. All simulation setups require that an MCS with a Fixture Offset of 1 be present even if unused. If a G55 through G59 are used in the G-code file then an additional MCS will need to be created for each of these. The Fixture Offset value that is entered in the MCS will be 2 through 6, respectively. Geometry view: Valitse MCS_MILL hiiren oikealla. => Edit-> Geometry -> MCS Huom!

3 3. Load the simulation machine into the part file. Machine tool view: 3

4 4. When loading the machine specify the Part Mount Junction so that the part can be positioned on the simulation machine correctly. Use the Workpiece Parts pane to select the part model to be used for Gouge Checking. Valitse työkappale: klikkaa kappaletta 4

6 5. Create all the tools in NX that will be used in the program. Add these tools to the Pocket with the correct Tool Number and then alter the Adjust and Cutcom Registers to match those used in the G-code file. If a Tool, Adjust or Cutcom value is used in the G-code file which cannot be found associated to an NX Tool than an error will be displayed during simulation.

11 7. To start the simulation go to Tools -> Simulate Machine Code File and, when prompted, select the G-code file that will be simulated. On the Simulation Control Panel check On the Show 3D Material Removal option and press Play to simulate. Make sure that a G20 or a G21 is included in the G-code file so that the machine simulates in the correct part units. Menu => Tools => Simulate Machine Code File 11
