5.) Calculate the machining time required to reduce from 60mm diameter shaft to 50mm diameter, for a length of 1500mm with depth of cut 2mm for rough cut and 1mm for finish cut. Cutting speed and feed may be assumed as 30m/min and 0.5mm/rev respectively.
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.
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 cylindrical workpiece has a 14.0 in diameter and has 30 in long. It is to be turned in an engine lathe at the following cutting conditions: cutting speed = 400 ft/min, feed = 0.015 in/rev, and depth of cut = 0.150 in. Determine the time to complete one turning pass if the approach and overtravel allowances are each 0.25 in (total = 0.50 in). Note: 1 ft = 12 in

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.
A twin-spindle drill simultaneously drills one ½-in hole and one ¾" through a 1" wide work piece. Both holes are twist drill with 118° point angles. cutting speed for material is 230 ft/min. The rotation speed of each spindle can be configured individually. The feed rate of both holes must be set to the same value, since both spindles go down at the same speed. The forward speed is set in such a way that the speed total metal removal does not exceed 1.50 in3 /min. Determine: a) the velocity maximum feedrate (in/min) that can be used, b) the individual feedrates (in/rev) that result in each hole and c) the time required to drill the holes.
