Material Figure 1-1 Part for Section 1Copyrighted Pro/Manufacturing can quickly become very involved and complex. This exercise is designed towork through a single manufacturing sequence to familiarize the user with the general procedureMaterial involved. Although a single manufacturing sequence (volume milling), it still involves a lot ofcommands. Since we’re just trying to gain familiarity with the general procedure, we’ll present this example with a minimum of explanation. At the beginning of each step we’ll explain whatwe’re going to do, then we’ll do it and at the end of the step we’ll tell you what we (and you)did. Later sections will go into detail about why you made the choices you were told to makeCopyrighted and what alternatives you have available to you.Produce the Part Model Material We’ll follow the steps discussed in the preface. First, 1) Produce the part model. Beforeentering the Manufacturing menu, enter the Part menu and create the block shown above. A click-by-click procedure is included in the Appendix A and B ...
