Circular drilling pattern, radial
Select Drilling
Select Drilling radial
Alternative: Select Deep drilling radial
Alternative: Select Tapping radial
Press the Pattern circular soft key
Press Pattern circular during drilling cycles to machine drilling
patterns in which the individual features are arranged at a regular
spacing in a circle or circular arc on the lateral surface.
Cycle parameters:
X, Z: Start point
C: Spindle angle – C-axis position (default: current spindle
angle)
Q: Number of holes
ZM, CM: Center pt. in Z, Angle of pattern center
K: Pattern diameter
A: Angle of 1st hole (default: 0°)
Wi: Angle increment – Pattern spacing (default: holes are
arranged at a regular spacing in a circle)
The parameters of the hole are also requested.
Cycle run:
1 Positioning (machine-dependent):
Without C axis: Position to the Spindle angle C
With C axis: Activate the C axis and position to the Spindle
angle C at rapid traverse
In Machine mode: Machining from the current spindle angle
2 Calculate the pattern positions
3
Position the tool at the Start point of the pattern
4 Execute the drilling operation
5 Position for the next machining operation
6 Repeat 4 to 5 until all machining operations have been
completed
7
Return to the Start point
8
Move to the Tool change point according to the setting in G14
