Controlled chattering on PMMA and epoxy: Effect of crosslinking and cutting speed on pattern formation

Controlled chattering is a cutting process with forced oscillation on the cutting tool, which creates wavy patterns on a variety of polymer surfaces with periods tunable from nano- to micrometer. It was found that the quality of surface finish after high-speed cutting was significantly improved when linear polymer chains are crosslinked. The pattern size (period) on thin sections is determined by the degree of crosslinking, which is dependent …
