Machining of Inserts with PCD Cutting-Edge Technology and Determination of Optimum Machining Conditions Based on Roundness Deviation and Chip-Cross Section of AW 5083 AL-Alloy Verified with Grey Relation Analysis

This paper describes the important significance of cutting-edge technology in machining polycrystalline diamond (PCD) cutting inserts by comparing evaluation criteria. The LASER is compared with grinding and electrical discharge (EDM) technologies. To evaluate data from experiments, Grey Relational Analysis (GRA) method was used to optimize input factors turning achieve required output parameters, namely deviation roundness chip cross-section. speed, feed rate, depth cut corner radius were applied experiment for three different levels (minimum, medium maximum). optimal aluminum alloy (AW 5083) determined factorial plan according Grade based on GRA multi-criteria parameters. results confirmed a verification test values recommended Al-alloy products. material currently being developed engineers forming selected components automotive railway industries, mainly reduce weight energy costs. best parameters obtained at speed 870 m/min, rate 0.1 mm/min, 0.5 mm 1.2 mm.
