To clarify the nature of the wear of the cutting tool during milling of glass-cloth of polymer materials laboratory study conducted at different cutting speeds. According to test results obtained curves of the wear of the cutting edge on a back surface, allowed to establish a sharp drop in tool performance with an increase in cutting speed. Studies show that during the running of the cutting tool is characterized by its intense wear and by varying the cutting speed is not more than 8 minutes. Therefore, the appointment of the cutting should be guided by a rational combination of performance cutting tools, surface quality and processing performance.
