| Abstract: | An analytical method based on discrete model was presented to detect and avoid interference for flat endmill in 4 axis NC machining. Based on the analyses conducted, an algorithm of interference free cutter location data computation for flat endmill in 4 axis NC machining was developed. Calculation examples showed that the algorithm could handle the interference problem in 4 axis NC machining with improved computation efficiency and stability. |
