Formation and Control of Feed Direction Burrs in Machining

Based on the metal cutting experiments, the forming model of feed direction burr is proposed in the paper, a physical parameter of determining the generating of type I feed direction burr - critical tool edge angle x' is given. And the main factors which influence x' are studied by the experiment, and related theory analysis is made. Furthermore, some new controlling methods and technology to restrain or decrease the feed direction burr in machining are developed.
