PrimeTurning™ Toolpaths
Mastercam has partnered with Sandvik Coromant to develop and support of their innovative PrimeTurning™ strategies and tooling. With these tools and methods, Mastercam allows you to turn in conventional turning and PrimeTurning directions. When combined with either CoroTurn® Prime A-type or B-type inserts (shown below), PrimeTurning provides superior metal removal rate, productivity gains of over 50%, and increased tool life in a variety of materials.
What makes PrimeTurning different from conventional turning strategies?
PrimeTurning allows for the ability to perform turning operations in all directions. This provides greater versatility when cutting as well as greater chip control and increased tool life, resulting in fewer tool changes and production stops.
What is important to know when creating a PrimeTurning toolpath?
- PrimeTurning toolpaths must be chained in the opposite direction as conventional turning toolpaths.
-
PrimeTurning toolpaths can only be used with Sandvik Coromant PrimeTurning tools. These are available in the following tool libraries:

What tool inserts are used for PrimeTurning?
PrimeTurning performs turning operations in all directions and utilizes two unique types of non-ISO inserts:
- A-type: Used for roughing, finishing, and profiling.
- B-type: Used for heavy roughing.
These inserts feature a chip thinning design, which lets PrimeTurning toolpaths run at double the speed and feed rates of conventional cutting strategies, with lower temperatures at the leading edge and away from the tool nose.
