The mechanism of chip formation is studied in order to find the optimum cutting condition for high polymers. The orthogonal machining operation was adopted to observe the phenomena of chip formation, and to measure the cutting force and the deformation of work material during cutting process for PTFE under machining conditions ; cutting speed : 0・02~762 m/min, depth of cut : 0・023 ~1・0 mm, rake angle of tool : -30°~40° having straight cutting edge. We choose as work materials Teflon No. 1 and No.5 which are de Pont's products. We found the peculiarities fall within cutting phenomena : (1) Types of chip : Two types of chip, continuous and discontinuous, appeared in whole range of our experiments (Photo.1 &2), and they were influenced by the cutting conditions, Chips formed at high cutting speed were varied form continuous to discontinuous due to decrease of rake angle (Fig.2), and chips at low speed were always continuous. (2) Deformation of work materials : The patterns of deformation of work material around the cutting edge were influenced by the rake angle as shown in Photo.3 and Fig.3. The amount of deformation were very large as compared with that in the case of metal cutting. (3) Cutting force required in machining : The larger the rake angle the smaller the cutting force and the more it turns from downward to upward (Fig.5&6). In the lower range of cutting speed, the cutting force decreases with decreasing cutting speed, but in the higher range, it decreases with increasing cutting speed(Fig.7). These phenomena may be explained by the time and thermal effects on the strength of work material in machining process.
