Abstract
Mechanical treatment of products made of glass-cloth to give them shapes and sizes, but it is an
intensive wear of cutting tools, selection of the fine chips and the appearance of surface defects. 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.
