Friday Tech Tip – Mastercam Simulator Engines

( The following piece comes from Mastercam Shop Talk, a digital newsletter that goes out to Mastercam Maintenance customers).

Mastercam X7 introduced the new Mastercam Simulator, unifying backplot and solid part cut simulation and providing a variety of additional tools.

Under the hood, the Mastercam Simulator switches between two engines; one dedicated to 2 & 3 axis machining, and one that expands that to include 5-axis machining. The reason is straightforward. The 3-axis engine doesn’t need to account for multi-axis moves, so it’s the faster of the two. Mastercam Simulator decides which engine to use based on the operations.

But did you know that you can override the Mastercam Simulator and tell it which engine to use? And more importantly, why would you want to do such a thing?

The Mastercam Simulator 5-axis engine continually tracks all sides of the stock, not just the area being cut. This is an obvious necessity because the part is always moving, rotating and shifting in different axes. If you have a 3-axis part that has features on the bottom that you want to see while operations are being done on the top, just tell the Mastercam Simulator to use the 5-axis engine.

The following pictures show the difference between the two engines:

3-axis engine cutting the top of a part.
5-axis engine cutting the top of a part with the same 3-axis toolpath, but also showing details of the part’s underside.
To switch between the two engines, select File > Options > General in the Mastercam Simulator window.
