A double-NURBS approach to the generation of trochoidal tool path
The International Journal of Advanced Manufacturing Technology, 2022 Abstract Trochoidal milling becomes a popular strategy in high-speed rough milling, thanks to its advantages in lowering cutting force (and tool wear) and increasing tool life. However, it also suffers from the disadvantages of low cutting efficiency and prolonged machining time due to its reduced cutter-workpiece engagement in the cutting area
