Preliminary analysis of grinding of PA66 thermoplastics

摘要

The intent of this work is to present a preliminary analysis of grinding of Polyamide 6/6 (PA66) thermoplastics searching for optimal process parameters sets. Natural PA66 parts were grinded with different cutting speeds, feed rates, depth of cuts and abrasive materials. Surface quality of the machined parts was measured and evaluated. The experimental procedure and the main results of the grinded surfaces were evaluated with the aim of achieving a final surface quality comparable to metallic material parts.
