Use of Chip Breaker in Machining | Mechanics of Machining

Need and purpose of chip-breaking Continuous machining like turning of ductile metals, unlike brittle metals like grey cast iron, produce continuous chips, which leads to their handling and disposal problems. The problems become acute when ductile but strong metals like steels are machined at high cutting velocity for high MRR by flat rake face type carbide or ceramic inserts. The sharp edged hot continuous chip that comes out at very high speed • becomes dangerous to the operator and the other people working in the vicinity • may impair the…
