The following data must be defined:
• The machining point (X, Y), the coordinate of the safety plane (Zs), the coordinate of the part
surface (Z), the total machining depth (P), the drilling peck (I) and the dwell at the bottom (t) and
the withdrawal distance after each penetration (B).
Drilling operation (level 3).
It may be used to set the withdrawal coordinate (Zr) after each penetration.
The following data must be defined:
• The machining point (X, Y), the coordinate of the safety plane (Zs), the coordinate of the part
surface (Z), the withdrawal coordinate (Zr), the total machining depth (P), the drilling peck (I) and
the dwell at the bottom (t).
Bore milling operation (level 5).
This cycle may be used to increase the diameter of a hole through a helical movement of the tool.
Besides this, if the tool allows it, it is also possible to mill a hole without having to drill it first.
The following data must be defined:
• The machining point (X, Y), the coordinate of the safety plane (Zs), the coordinate of the part
surface (Z), the hole diameter
