Solution for ME324 HW #4 1. SOLUTION All the operations can be performed on a milling machine. The stepped cavity is made through a end milling operation. The holes are obviously drilled and tapped. The slots on the sides are milled with slotted cutters. The corners are removed by a face milling or end milling operation. Note that the holes may be obtained on a drill press as well, so that the capital cost of the mill on the part is minimized. The order is somewhat arbitrary, except that the contouring and face mill- ing should be done before slotting and drilling, and drilling has to be done before tapping. 2. SOLUTION The cutting speed is the tangential speed of the workpiece. The maximum cutting speed is at the outer diameter and is obtained from the expression and the cutting speed at the machined surface diameter is From the data given we note that the depth of cut is and the feed is Thus according to Eq. the material removal rate is The actual time of cut , according to Eq.
