HEIDENHAIN CNC Pilot 4290 - Manual (Page 114)

4 DIN PLUS 102
Line segment in a lateral surface contour G111-Geo
Parameters
Z:
End point
C: End point (end angle)
CY: End angle as linear value (referenced to unrolled reference
diameter)
A: Angle (reference: positive Z axis)
B: Chamfer/rounding arc – transition to the next contour
element. Program the theoretical end point when you enter a
chamfer/rounding arc.
■ No entry in B: tangential transition
■ B=0: no tangential transition
■ B>0: Radius of the rounding arc
■ B<0: Width of chamfer
Q: Selection of intersection – default: 0. End point, if the line
segment intersects a circular arc.
■ Q=0: near intersection
■ Q=1: distance intersection
Programming
■ Z, CY: Absolute, incremental, modal or ”?”
■ C: Absolute, incremental or modal
■ Program either Z – C or Z – CY
4.5.7 Lateral Surface Contours
Starting point of lateral surface contour G110-Geo
Parameters
Z:
Starting point
C: Starting point (starting angle)
CY: Starting angle as linear value (referenced to unrolled reference
diameter)
Program either Z, C or Z, CY.
