Johnson-Cook constitutive model is still the most used in metal cutting simulation, although several drawbacks reported literature. A high number of parameters can be found literature for same work material. One question that may arise “What suitable set a given material?”. The present paper puts evidence some issues related with selection these from In this contribution, two sets Ti-6A-4 V are evaluated, using three types models. These models based on different formulations: Lagrangian,...
In this study, an attempt has been made to statistically model the relationship between cutting parameters (speed, feed rate and depth of cut), force components ( Fx, Fy Fz) workpiece absolute surface roughness Ra). The machining case a martensitic stainless steel (AISI 420) is considered in common turning process by means chemical vapor deposition–coated carbide tool. A full-factorial design (4 3 ) adopted order analyze obtained experimental results via both analysis variance response...
Long-term wear tests on the CBN tool behaviour during hard turning of AISI D3 (60 HRC) have been investigated. The evolution surface roughness, cutting forces and temperature has studied according to parameters wear. Results show that is resistant despite aggressiveness steel. A great part heat generated mainly dissipated throughout chip; at a speed 320 m/min chip found be 14 times higher than recorded in workpiece. range 90 240 suitable cut this material. former appropriate respect...
