Performance of laser surface textured high speed steel

This textured cutting tool was then used in orthogonal dry machining of Al7075-T6 aerospace alloy and compared with the performance of conventional tools. Use of textured cutting tools resulted in reduction of both cutting and thrust forces. The tool-chip contact length is also less in the case of textured tool.
