Cut Tolerance

Introduction

This topic will explain Cut Tolerance, describe where to access it, and provide an example.

Cut Tolerance

The Cut Tolerance is the tolerance used for the accuracy of the toolpath. This value is the chordal deviation of the toolpath against the surfaces to be machined. In other words, the toolpath can have a maximum error to the surfaces in the range of plus or minus the cut tolerance. A small cut tolerance gives you more toolpath points on the drive surface, so the generated toolpath is more precise to the surface contour. The result of the machining is a very good surface quality but it takes much more time to calculate.

Navigation

To access the Cut Tolerance in the Mill Multiaxis Wizard:

 

• In the Surface quality group, of the Surface Paths tab, enter a value next to Cut Tolerance.

Parameters

 

• Cut Tolerance - represents how much the toolpath may vary from the selected geometry.

Example

• A large cut tolerance generates fewer points in the toolpath. After machining the surface is rougher. Therefore the calculation time is much faster.

 

 

• A small cut tolerance generates more points on the surface. After machining the surface is finer.
