12.1.2 Machining movements
There are four work planes in all the operations:
• Starting plane or tool position when calling the cycle Zi). No need
to define it.
• Safety plane. It is used for the first approach and to move the tool
between machining operations. It is defined by cycle parameter Zs.
• Part approaching plane. No need to define it. It is calculated by the
CNC, 1 mm off the part surface.
• Part surface. It is defined using the Z parameter.
When executing the cycle, the tool moves in rapid (G0) to the safety
plane (Zs):
• If the starting plane is above the safety plane (left figure), it first
moves on X, Y and then on Z.
• If the starting plane is below the safety plane (right figure), it first
moves on Z up to the safety plane and then on X, Y.
Then, it moves in rapid (G0) to the approach plane and finally at
working feedrate to carry out the machining operation.
Once the machining operation has concluded, the tool returns to the
safety plane (Zs).
