Cam Chapter 2 Page 33 of 96 At the profile editor, draw the geometry to be emptied. Before beginning to define it, bear in mind that you're going to machine; therefore, you will have to use a tool with a certain diameter. Pay attention to the geometry of the drawing so the tool can work inside it since it is an emptying operation. · This is the theoretically drawn geometry; but, as may be seen in the drawing, the tool could never machine the programmed corners because it does not fit. Therefore, the tool must be given some relief in those four corners. · For example, this would be the best way to program this profile.
