Revisiting the Possibility of HighSpeed Polymer Composite Processing

Experiments showed the possibility of processing polymer composite materials (PCM) at high supercritical cutting speeds when the processes of thermal degradation are intensified, resulting in an unacceptable degradation of the processed surface. The design of the laboratory setup is described. It allows carrying out experimental studies of the process of PCM cutting within a wide range of both work spindle speeds (from 225 to 18 000 min^-1) and cutting speeds up to 117 m/s. A physical justification for the existence of two possible intervals of PCM processing speeds: conventional and high-speed cutting is provided.
