In breaking edge and chamfering operations, there is a safety distance (Z) and a peripheral safety distance (XY).

 If the tool is below these values during machining, the operation will not be performed.

We need to consider these safety distance values to be sure to have no clashes.

CAUTION:

Reducing one of these safety distances will affect all automatically calculated altitudes (Finish, Stock, and Automatic modes).

These altitudes must therefore also be checked.
