A part (sketch of part attached) is to be turned on the lathe using 1 rough pass

Question

A part (sketch of part attached) is to be turned on the lathe using 1 rough pass at maximum power of the machine (5hp) and one fininshing pass using a depth of cutt of .015in and suggested speeds and feeds using the material (Low carbon steel free machining) and table 7.6 (attached) to determine speeds and feeds of finish pass. The cutting tool is a brazed carbide. Calculate the machining time of both roughing and finish passes. Hint (use 5hp and volume of material removed to determine roughing pass time, for finish pass use length of cut and speeds and feeds (determined using table 7.6 attached) to determine time for finishing pass. Suggested equations below.

Machining time for turning workpiece Work surface Transient surface Machined surface Primary motion Tool Continuous feed motion. im Machining time for one pass, Unit: min l Length of cutting n, Rotational speed of the workpiece Unit: rpm f Feed rate of tool relative to the workpiece Direction, unit: per revolution

Explanation / Answer

The answer of following question is as follows

The required machining time for the given lathe is 7min.
