The position of clamps on the workholder is just as important to the overall operation of the tool as the position of the locators. The selected clamps must hold the part against the locators without deforming the workpiece. Once again, since the purpose of locators is to resist all primary cutting forces generated in the operation, the clamps ...

This process can be done on the top, bottom, or both sides of the weld. Since the milling operation produces a large amount of scrap chips, it is usually done at a station adjacent to the welding area instead of in the same area. As with welding, the strip must be securely clamped to ensure proper function of the milling unit.

CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4-axis, and 5-axis. However, the term 2D is a bit misleading since this toolpath uses the Z-axis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.
