Investigation of machining performance of coated alumina cutting tool insert with sand blasting surface pretreatment

The sand blasting process had been used as a process of surface pretreatment for the alumina cutting tool. The cutting tool insert were received as amorphous graphite deposited by using PVD technique. Machining workpiece was conducted on Ti alloy. Morphological observation by metallurgical microscop...
