Abstract
This paper describes a behaviour of the orthogonal cutting strain in the aluminum workpiece. The cutting strain is measured with a fixed quantity by a photoelastic coating method. The components of an instantaneous cutting strain and a residual one are separated from the observation. The results obtained through this study are as follows : (1) The comportment of the cutting strain in the ductile material is disclosed using the photoelastic coating method. (2) The behaviour of the cutting strain in the strain hardening material is similar to that of the elastic material.
