Chip Formation in Orthogonal Cutting of Corrax PH Steel
Ahmet Serdar Güldibi Halil DEMİR
AbstractCorrax steel belong to the PH martensitic stainlesssteel family and it’s mechanical specifications and chemical composition are similar with PH 13-8 Mo. PH steels offer to the users high strength and hardness through precipitation hardening. The high specifications and high ductility of this steel make it hard to machine. Especially high ductility causes lamellar and continuous chip formation in machining. This type of chips coils up to the workpiece and cause surface defections on the workpiece surface. This study investigated the different chip formations in orthogonal machining of Corrax Steel. Results shows the high cutting speeds and high feed rates breakes the chips instead of low cutting speeds and low feed rates.
