Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 95 === A process planning strategy was proposed to suppress the wear effect of tool in a polishing of axially symmetrical work. This strategy can keep machining rate of tool to be constant. In study, we need to design the proper dwelling time distribution for tool to remove error of axially symmetrical surface and use computer to simulate. Observe the residual error on surface of work. Analyze the outcome of experiment and estimate feasibility of the strategy. According to the way of motion of tool, it could cause two difficulties:
1.To design the dwelling time distribution of tool will be more difficult.
2.The load of tool will be unstable.
In order to solve this first difficulty, in a new strategy of working, the dwelling time distribution of tool must be a multiple of integral of the period of work rotation. And experiment to prove it, analyze and discuss the outcome of experiment.
Second problem cause the load of tool to be unstable in experiment. To improve the load of tool, a new strategy was proposed to control load and to verify effectiveness for the strategy.
Finally, analysis and discuss the outcome of experiment, and estimate the practicability of the strategy.
