Abstract

A system for predicting the machining error for a batch of parts in CNC wheel grinding is described; the system takes the influence of technological variables into account. Analysis of their combined influence on the machining error is based on a digital twin of the plunge grinding process. The variable machining conditions for the batch of parts (shafts) is taken into account by simulating the influence of the following factors on the machining precision: fluctuations in the margin; the blunting of the wheel grains before dressing; the pliability of the machining system over the grinding length; and positions of the active monitoring instrument in cross sections of the workpiece corresponding to different pliability of the machining system.
