Abstract

Plastics are very common materials that can be diamond turned and widely used in optics and our ultra precise applications. Surface texture parameters (Roughness and waviness) are very important considerations in these applications. In this experiment single point diamond turning is done on polycarbonate for about 200Kms length of machining. Surface roughness and waviness are plotted against machining time after certain no. of cycles. After machining 9Kms, surface roughness value was less than 15nms.With increase in machining time Ra values was increasing. Machining was stopped when roughness value crossed 70nm .Waviness also increased with machining time. Waviness was below 1 µm up to 7 Kms. Further machining resulted in increased waviness .As polycarbonate is plastic, linear trend is seen in both roughness and waviness.
