Abstract

Experiments were made for the internal turning of Teflon at high feeds, collecting the resulting chips. There were studied the chips and the machined surfaces using a magnifying glass and a microscope. The shapes and dimensions of these chips were analyzed, explaining their correlation with the feed and with the deformation of the chips sections. The cutting process was evaluated by correlating the shapes of the chips with the plastic deformation phenomena occurred in the cutting area. The sections of the chips were measured and their deformability was determined using the cutting relationships. From the analysis of the shapes of the chips, conclusions can be drawn regarding the deformation of the part material in the cutting area, meaning an appreciation of the machinability of the material. All these considerations, as well as the final table regarding the deformation of the chip during processing, show how Teflon behaves during internal turning with high feeds. The measurements carried out during this research showed that significant plastic deformations occur in the cutting area at the internal turning with high feeds of this type of non-metallic material.
