An Analysis of Chip Formation in Wood Machining

Chip formation during orthogonal cutting was analyzed with aid of the following equipment: 1) A milling machine, using cutting velocities of several inches per minute, 2) a dynamometer, and 3) a 16 mm motion picture camera. This report indicates that the wood cutting process involves the formation of basic chip types with associated surface characteristics. When cutting parallel to the grain, chip formation may be classified as: Type I, where splitting ahead of the cutting edge may result in the defect chipped grain; Type II, in which continuous diagonal shear produces excellent surface quality; and Type III, where compression and shear failures in the wood often cause the resultant surface to be fuzzy.
