Feed Rate Calculations Feed rate calculations for the lathe and other machine tools are dependent upon many factors. The primary factors we are concerned with are: 1. Surface finish desired on the part. 2. Cutting tool nose radius. 3. Strength of the setup. Depth of cut is a minor influence upon the choice of feed rate when rigidity and power are good. The surface finish is primarily dependent upon the shape of the cutting tool and the feed rate . A fast feed rate will quickly produce a rough surface finish. A slow feed rate will provide a smoother surface finish but will take more time to produce. Which surface finish is more expensive to produce, smooth or rough? Typical feed rates for our lathes and cutting tools in Stout's machine shop are: finish cut .002 - .003 inches per revolution medium cut.005 in/rev rough cut .008 - .012 in/rev Notice these feed rates are listed in feed per revolution. That means that every time the spindle rotates one revolution the tool will advance across the workpiece the stated
