EFFECT OF FEED RATEAND RACK ANGLE ON CUTTING FORCE AND GENERATED TEMPERATURE IN AN ORTHOGONAL TRUNING PROCESS

Mechanical

Abstract

In this research, a FEM simulation of orthogonal turning process is made. The effects of feed rate and rack angle of cutting tool on cutting force and generated temperature are analyzed. The analyses are curried out using MSC Marc 2013. Cutting tool is considered rigid in the modelling. While work hardening of workpiece material is considered in analysis to provide more accurate results. The results are compared to previous experimental analysis for same material and cutting conditions and show good agreement. Current analysis show that cutting forces increase with the increase of cutting feed, and decrease with the increase of rack angle of cutting tool. Results also show that the temperature rise increase significantly with increase of cutting feed, while change of rack angle does not have clear effect on temperature rise.
