Summary
On the basis of previous works, general problems of optimizing metal cutting process are further discussed. The prerequisite for the optimum control of the metal cutting process is to seek out the dynamic characteristics of both the machine tool and the metal cutting process which are most conformable to reality. Experiments aimed at identifying metal cutting process in lathe with their results are presented. In experiments, cutting depth and width simulating impulse signal are used. By means of the system approach and the techniques of DFT and FFT and by making use of the curve fitting method, dynamic characteristics of both the machine tool and the cutting process are obtained, empirical formulas for dynamical cutting force are presented. On the basis of which, prospects of optimization of the metal cutting process are discussed. Scheme of a compensating device for the purpose of attainment of the best surface finish and geometrical accuracy of the workpiece are presented and simulated on an analog computer.
