Effect of Coated Composite Micro–Texture Tool on Cutting Shape and Cutting Force during Aluminum Alloy Cutting

Aluminum alloy materials are very difficult to break in the processing process; chip accumulation leads poor stability. In this paper, a coated composite micro–textured tool is presented. The influence of on shape and cutting force under same parameters studied. Firstly, combination temperature optimized based test. Secondly, combined with finite element simulation technology, three kinds micro–texture tools tested determine parameters, workpiece materials, optimize from angle shape, force. Finally, basis optimizing microstructure combination, optimization performance aluminum by coating material It was found that more easily broken when two were used. decreased 25% 9.09% compared non–micro–texture tools. 3% 4.99% those uncoated microstructure.
