| Summary: | 碩士 === 國防大學中正理工學院 === 兵器系統工程研究所 === 89 === Drilling is widely employed in machine manufacturing process. Although the deviation effect of the diameter is unavoidable during drilling. We cannot disregard it because it can influence the precision and interchangeability of the products. This study analyzes the factors of the deviation effect from twist drills、bench drill press、coolant、fixture and the workpiece materials (S25C low carbon steel and brass). Further work on the study is to make an experiment for the two materials on changing the rotational speed、cutting lip length、point angle of the drills . The results show that the smaller deviation comes from some conditions, which include a certain rotational speed、cutting lip length、point angle of the drills. The skilled labor in the factory can use these parameters to upgrade the precision and interchangeability of the products.
