Elements
Example: G22-Geo
Recess (general) G23-Geo
G23 defines a recess on the previously programmed linear reference
element. On the lateral surface the reference element can be
diagonal.

Parameters
H Type of recess (default: 0)
„ H=0: Symmetrical recess
„ H=1: Relief turn
X Center point of recess on the face (diameter)
Z Center point of recess on the lateral surface
I Recess depth and recess position
„ I>0: Recess at the right of the reference element
„ I<0: Recess at the left of the reference element
K Recess width (without chamfer/rounding arc)
U Recess diameter (diameter of recess base). Use U only if the
reference element runs parallel to the Z axis
A Recess angle (default: 0)
„ H=0: 0° <= A < 180° (angle between recess edges)
„ H=1: 0° < A <= 90° (angle between reference line and recess
edge)
