Ensuring accuracy of contour milling on CNC machines
Mechanics and Advanced Technologies, 2023 Contour milling is characterized by quasi-stationary, which leads to the occurrence of a machining error caused by elastic deflections of the machining system. Moreover, such an error cannot be eliminated by sub-adjusting the control program "for size", since it not is constant and changes along the contour in a wide range.
