Chip thickness equation
WebJul 1, 2014 · The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). WebThe chip thickness is an important consideration when deciding the feed per tooth, to ensure that the most productive table feed is employed. Average chip thickness, h m A …
