本論文之研究目的為利用撓性刀座在車削作業時發產生微切深及
微進給的效應,以達到以較不精確的加工機器加工出較精確的工件之
目的,亦即所謂PMWPM 之加工策略。本研究首先參考文獻中八角環動
力計之弱化結構,設計出兩款不同軸向之撓性刀座,並經有限元素法
模擬驗證其刀座的作動趨勢,再利用快速原型機製作出該兩款的撓性
刀座並以實驗量取其受力及位移之關係,最終再將其撓性刀座置於車
床上進行切削實驗,其撓性切削系統為ABS 材質之撓性刀座配合壓電
致動器及電壓放大器,經切削實驗結果顯示切削力(F)最大可改善
70.81%,表面粗操度(Ra)最大可改善67.37%,其微切深效應經量測
最小可達2μm,超越了車削加工工具機的切深最小精度10μm,而工
具機進給在0.12(mm/r)時其微進給效應可達0.08(mm/r),故達到了
PMWPM 之加工策略。
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.
