| Abstract: | Machining errors caused by cutting force are studied in this paper,and an algorithm to simulate errors is putted forward. In the method,continuous machining process is separated into many machining moments. The deformation of work-piece and cutter at every moment is calculated by finite element method. The machined work-piece is gained by Boolean operation between deformed work-piece and cutter. By analyzing data of final work-piece,machining errors are predicted. The method is proved true by experiment. |
