Modelling and simulation of turning processes

Abstract

A block-diagram model of the cutting process in the turning operation has been developed through an analytical approach in order to predict the cutting forces. This gives a fundamental idea about cutting forces acting on the axis-drive and spindle-drive systems that can be used in machine tool virtual prototyping. The aim of this paper is to analyse the process in physical terms and hence to develop a cutting process model that relates the feed rate and spindle speed to the cutting forces generated. The model presented here permits a better understanding of the cutting process and its interaction with the machine tool, and can be used as a part of an integrated computer-aided engineering design tool. Model parameters were measured experimentally so that the model can be simulated. The results of the simulation were compared with data obtained during cutting operations.
