The aluminum alloy part shown in Figure 7.57 is to be produced on a small machining center
Question:
The aluminum alloy part shown in Figure 7.57 is to be produced on a small machining center from a piece of bright drawn rectangular bar of cross-section 3 in. × 2 in. The machining operations required are as follows:
a. Finish face mill the top surface to reduce the part height to 1.75 in. with a brazed carbide face milling cutter.
b. Rough and finish the two 1 in. × 1.25 in. steps in the parts with a high-speed steel end milling cutter.
c. Finish mill the 0.5 in. × 0.25 in. in the top surface of the part with a high-speed end milling cutter.
d. Drill six 0.5 in. diameter holes with a high-speed steel drill. Using the worksheet in Figure 7.9 and the data in this chapter, estimate the processing time and costs for a batch of 200 parts.
