Abstract
This study was made to clarify some effect of cutting condition and machinability of plastics within the range of flowtype cutting.
The results obtained are as follows :
1. Within the range of 70°100° of cutting angle, the cutting resistance and shear angle are in proportion to the cutting angle.
2. When the depth of cut becomes over O. 05mm, specific cutting resistance comes to he almost constant.
3. As cutting speed becomes higher, cutting resistance decreases and the shear angle increases.
