Figure 9.8: Scallop Tool Path |
Scallop tool paths, when viewed from the top, appear similar to 2D spiral pocket tool paths. Scallop paths continually change the stepover distance to maintain a constant scallop height over the entire part.
Scallop tool paths are calculation intensive and may not work on all shapes, and produce very large CNC programs with many short moves.
Yet, when applied properly, they work very well and produce a superior surface finish.
