| Summary: | 碩士 === 國立屏東科技大學 === 工業管理系 === 93 === The aim of the study was to explore the effects of the angle of elevation, position of auxiliary handle and three operation planes on the performance of loading and unloading screws into angle iron, deviation from target and RPE for cordless power tooling. Eleven male subjects were recruited in the study. The results show that the positions of auxiliary handle and operation planes have significant effect on operation performance, deviation and RPE. The angle of elevation of tooling has no effect on those response variables. Finally, the original design (without handle) is the best one among all cordless power tooling in operation performance. However, the RPE’s results support the one with 1800 handle because all subjects feel the most comfortable on the part of hand between their thumbs and their index fingers.
