Recess (general) G23–Geo
G23 defines a recess on the previously programmed linear
reference element. The reference element can also be oblique.
Parameters:
H: Kind of recess (default: 0)
0: Symmetrical recess
1: Relief turn
X: Center point of recess on the face (no input: Position is
calculated; diameter value)
Z: Center point of recess on the lateral surface (no input:
Position is calculated)
I: Depth
I > 0: Recess at the right of the reference element
I < 0: Recess at the left of the reference element
K: Breadth (without Chamf./round.)
U: Recess diameter – diameter of recess base
Use U only if the reference element runs parallel to the Z axis.
A: Angle (default: 0°)
H = 0: Angle between recess edges (range: 0° <= A < 180°)
H = 1: Angle between reference line and recess edge (range:
0° < A <= 90°)
B: Outs.rad./cham. at corner near the starting point (default: 0)
B > 0: Radius of rounding
B < 0: Width of chamfer
P: Outs.rad./cham. at corner far from the starting point (default:
0)
P > 0: Radius of the rounding arc
P < 0: Chamfer width
R: Inner radius in both corners of the recess (default: 0)
FP: Do not machine the element (only necessary for
TURN PLUS)
1: Yes
BE, BF, BD, BP and BH.

The control refers the Depth to the reference element.
The recess base runs parallel to the reference element.
