Control Stock Extension for 3‑Axis Toolpaths

A new Extend 3-axis tooling option has been added to the Stock Model operation.

This option controls whether Mastercam extends the cutting area of the 3-axis toolpath beyond the defined stock boundaries during calculation. In previous versions, when the tool flute length was shorter than the material being removed, Mastercam automatically extended the tool flute length upward to ensure stock removal. While typically effective, this extension method could produce unintended stock removal when using right-angle heads.
