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.
