12.1.25. Stepping

When an operation is too deep to be done in one cut, you can split up the cuts in several cutting layers. Consider the following simple part:
The slot is very deep and might damage the machine or the tool.
Let's use the Stepping function to divide the cut in several cuts at descending Z level.
Open the parameters for the contour cut layer and click on the Stepping tab.
Click the Use Stepping check box to enable stepping.
You can either accept the calculated default values or enter your own.
The contour cuts will now be repeated at descending depths for less strain on the machine/ tool.
Please note that the actual values depends on many factors like machine quality and strength, material of workpiece, workpiece finish and tolerance, type of tool and economy.
The same part with Stepping activated. We have used the cutting function in the CNCSimulator to cut the front off so you will see the toolpaths better.
Ramping and Stepping can be combined. See Ramping.
