ResumoPrecision turning of polymeric materials increases form and shape accuracies in respect to the conventional techniques, but the relatively large tool wear of the mono-crystalline diamond tools may be a problem. This paper will discus possible tool wear mechanisms that occur during diamond turning of glassy (amorphous) polymers. Special attention is given to thermal-oxidative tool wear, tribo-electric tool wear and tribo-chemical tool wear. It will be shown that tribo-electric and tribo-chemical tool wear play an important role in the precision turning process of polymers.
