Establishing Effect of Machine Tool Errors on Accuracy of Turned Components

  • R. Marsh

Summary

This paper describes how the thermal distortion, turret indexing errors and inherent variations in a centre lathe can be combined to predict the overall working accuracy of a turned component. Surface roughness is shown to be a function of not only the processing conditions, such as feed rate and tool nose radius, but also the effect of machine tool deflections and yaw motion of the saddle. Finally, an adaptive control algorithm is recommended as a means to modification of control system instructions to the axes drives of a computer numerical control (CNC) lathe so as to maximize the quality boundary of a programmed component.
