Position pattern
In drilling and milling operations with face B, position patterns "full circle/pitch circle" provide the
following options for machining on inclined surfaces
● with swivel plane
● with C axis
Procedure
1.
Press the "Drilling" softkey.
2.
Press the "Positions" and "Full circle/pitch circle" softkeys.
Parameter
Description
Unit
Face B on the swivel plane
Z0
Z coordinate of the reference point (abs)
mm
X0
X coordinate of the reference point (abs)
mm
Y0
Y coordinate of the reference point (abs)
mm
α0
Starting angle: Angle of 1st hole with reference to X axis.
Positive angle: Full circle is rotated counterclockwise.
Negative angle: Full circle is rotated in clockwise direction.
Degrees
α 1
Indexing angle: After the first hole has been drilled, all additional positions are ap‐
proached at this angle (only for pitch circle).
Positive angle: Additional positions are rotated in counterclockwise direction.
Negative angle: Additional positions are rotated in clockwise direction.
Degrees
R
Radius of full circle
mm
N
Number of positions on circle
Positioning
Straight line: Next position is approached linearly in rapid traverse.
Circular: Next position is approached along a circular path at the feedrate defined in
the machine data.
