The Simulation of Cutting force Estimate Model at Micro-Stage for Ultra Precision Cutting Machine of Nano Part

나노부품 초정밀가공기용 마이크로스테이지의 절삭력 예측모델 시뮬레이션

Recently, according to the development of mechatronics industry that was composed of NT, ST, IT, RT and etc, the 1 necessity of nano-parts was increased. Because of the necessity, this research was started for improving work precision of the parts as fixing UPCU( Ultra Precision Cutting Unit)on lathe. So, in this research we executed the modeling of UPCU (Ultra Precision Cutting Unit) by the application of PZT, the relationship between the displacement of tool in UPCU and the cutting force of it has been in take a triangular position in the case of plane cutting. The modeling of system that is containing the fine displacement was performed. Also, we found like to find the optimal cutting condition through the simulation of relationship between the displacement and the cutting force.
