Abstract

In clean and fine turning on CNC machine tools, it is advisable to carry out active control by measuring the parts after their processing. With this type of active control, accuracy is highly dependent on dimensional dispersion caused by random factors. A solution for reducing these errors and increasing the accuracy of active control is the use of adaptive control of roughing accuracy.
