プラスチックの穴あけ加工に関する研究（3）：逃げ角が加工精度におよぼす影響 Study on Drilling of Plastics (3rd Report) 加畑, 信一 佐藤, 元太郎 田野口, 睦 The analysis of cutting resistance and friction in metal Cutting has so far been discussed without regard to the rubbing force which acts upon the clearance flank of cutting edge. But the rubbing force is very important factor in the study on the plastics drilling phenomena. So this paper describes about the values of rubbing force obtaind by orthogonal Cutting in steel and plastics. Furthermore the accuracy of drilled holes on plastics were discussed in connection with the rubbing force. The Results were summarized as follows. In the orthogonal Cutting Test, the values of Rubbing force were rather greater in plastics than steel. These results may be mainly due to the fact that in the contact area between the Clealance flank of cutting edge and material, there is difference between steel and plastics. In the drilling of plastics, the relaiton between the relief angle and the accuracy was remarkable particularly, the decrease of torque had good effects on the accuracy.
