Roughing Scans and Entry and Exit Parameters

For roughing sequences, there are a number of parameters that control the roughing scan type. You can also vary the entry and exit methods for closed and open areas. High Speed Roughing Scans • OPEN_AREA_SCAN and CLOSED_AREA_SCAN – CONSTANT_LOAD (default for closed areas) – MAINTAIN_CUT_TYPE – MAINTAIN_CUT_DIRECTION – FOLLOW_CONTOUR (default …

Basic Roughing and Re-roughing

Roughing and re-roughing sequences are intended for high speed mold machining, and for machining imported, non-solid geometry. You can use these NC sequences to produce more efficient toolpaths when machining mold cavities or pockets. Roughing and Re-roughing Sequences • Roughing – High speed mold machining and machining imported geometry. – …

Cut Line Surface Milling

Cut line surface milling enables you to specify the shape of the first, last, and optionally some intermediate cuts. The toolpath gradually changes the shape of the cuts according to the surface topology. Cut Line Surface Milling: • Mill surfaces using cut lines. • Toolpath gradually changes shape. • Open or closed …

Understanding Surface Milling

You use surface milling to mill horizontal or contoured surfaces. There are four types of surface milling sequences that you can configure. It is important to understand the benefits of each type of surface milling sequence. Surface Milling • Machine horizontal or contoured surfaces. • Continuous toolpath required. • Cut types: – Straight …
