Textbook Question
Chapter 40, Problem 4P
Notice that the holes in the part in Figure 49.9 need to be countersunk after they are drilled. How can the jig be designed to put the countersinks on the mounting holes while the part is in the jig, or would this operation be done afterward?

The workpiece is 1.0 inches thick. Both drills have point angles of 118 degrees and the cutting speed for the material is 300 ft/min. The rotational speed of each drill can be set individually but the feed rate for both holes must be set to the same value because they move together into the material. The feed rate is set so that the total metal removal rate of both drills combined does not exceed 1.50 in3/min. Determine (a) maximum feed rate (in/min) that can be used, (b) individual feeds (in/rev) for each hole, and (c) cutting time for the operation.arrow_forward
