Figure 7.4: Prismatic Part (Orientation in CAM) |
Figure 7.1 shows the part oriented as it is modeled in the mechanical CAD software. For CAM, it is helpful to display the part in the same orientation as viewed while sitting on the CNC machine. For a Vertical Machining Center (VMC) this requires updating standard views to look like those shown in Figure 7.4. The G-code file is generated in relation to the Work Coordinate System (WCS), so changing views is not required for CNC programming. It simply helps visualize CNC machining processes when using CAM.
