A Higher-Order Formula of Path Interval for Tool-Path Generation
International Journal of Automation Technology, 2011 This paper presents a novel fourth-order formula for determining path intervals and comprehensively considers path interval formulas. In tool-path generation, a path interval is generally formulated as a scallopheight polynomial. Controlling scallop height in mechanical machining improves surface roughness or machining efficiency.

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
