A part to be turned in an engine lathe must have a surface finish of 1.6 μm. The part is made of a free machining aluminum alloy. Cutting speed = 150 m/min. The nose radius on the tool = 0.75 mm. Determine the feed that will achieve the specified surface finish.
If a fairing operation is executed at a rotational speed of 40.0 rev / min, the feed is 0.015 in / rev and the depth of cut is 0.180 in, it determines: a) cutting time to complete the fairing operation; and b) the cutting speed; and c) The speed of metal removal at the beginning and end of the cut d) The power dissipated.
A two-spindle drill cuts two holes at the same time, one 1/2 inch and one 3/4 inch. 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.
