碩士 === 國立臺灣海洋大學 === 機械與輪機工程學系 === 93 === The purpose of this paper is to develop suitable micro depth of cut and micro feed of an existed turning machine a way for parameter sach as in order that the concept be precision machining without precision machine (PMWPM) can be implemented. In the study, the compliance system was devised by dynamometer of octagon ring type structure and analyzed at the first stage, and then a rapid prototyping (RP) process was applied to make it. For studying the effect of two kind of octagon ring the cutting depth and feed were used. The calibration of the system was conducted to verify the linearity of its displacement. The compliance tool fixture system of tool comprises a tool apron made fromABS, piezoactuators device and piezo amplifiers. Finally the turning experiments were executed to study the performance of applying the compliance system of cutting tool. Experimental results showed the cutting force was most reduced up to 70.81%, the surface finish improvement was up to 67.37%, and the micro depth of cut less than 2μm. In conclusion, above imprecision is superior to the original machine precision 10μm, and the micro feed of cut achieve 0.8mm/r when the feed set 0.12mm/r; therefore, the experiment achieves the PMWPM Processing strategy.
