    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.
