Feed drive errors in a metal-cutting machine and ways of reducing them

An analysis of the influence of mechanical processes of metal milling on the accuracy of machining by a working body (a table with a workpiece) when the feed is controlled by a software program through a series of electric drives is an important problem. A review of literature revealed a lack of works on the estimation of force pulsations in the cutting zone during milling and their effect on the feed drive movement. To solve this problem, the authors of the article developed a mathematical model of the milling process that took into account two degrees of freedom, using which a simulation model was obtained to study pulsations of the force in the cutting zone in magnitude and direction. The study showed that during milling, especially with cylindrical and face mills, the amplitude of force pulsations in the cutting zone can reach 50% relative to the average value. The study of the influence of the milling parameters on the relative movement of the working body and the cutter made it possible to establish a relationship between the rotational speed of the cutter, feed per tooth and positioning error, as well as the error due to the characteristics of the feed drive. Expressions of the load torque fluctuations of the output shafts of the electric drives and the fluctuations of their rotation speeds caused by force pulsations were obtained.
