Abstract
The paper attempts to implement the multi objective optimization methodology for poly-ether-ether-ketone (PEEK) polymer by using CNC turning machine. For the same, Taguchi based L18 experiments were carried out on CNC turning lathe using TiC and TiN coated carbide inserts. Further, the process performance is measured in terms of cutting forces and surface roughness. The optimized machining parameters were determined using Grey Relational Analysis (GRA). The analysis of results shows that cutting speed: 377 m/min, feed rate: 0.05 mm/rev, depth of cut: 2 mm and TiC insert exhibits better results.
