3.1.2 Safety plane
There are four work planes in all operations:
• Starting plane or position occupied by the tool when calling the cycle. It is not defined; the CNC
sets it.
• Safety plane. It is used for the first approach and for withdrawing the tool after the machining
operation. It is set with parameter Zs.
• Part approaching plane. The CNC calculates it, at 1 mm from the part surface.
• Part surface. It is set with parameter Z.
The tool moves in rapid (G00) to the safety plane (Zs), moves on in rapid to the approach plane (up
to 1 mm off the part surface) and then moves at machining feedrate (G01) up to the part surface.
Approach to the part surface
The approach to the part surface depends on the current tool position.
• If it is above the safety plane (left figure), it first moves in X, Y and then in Z.
• If it is below the safety plane (right figure), it first moves in Z to the safety plane, then in X, Y and
finally in Z to the part surface.
