Recess (general) G23-Geo
G23 defines a recess on a linear reference element (G1). G23 is
assigned to the previously programmed reference element. On the la-
teral surface the recess can be positioned on an inclined reference
straight.
Parameters
H:
Recess type – default: 0
■ H=0: symmetrical recess
■ H=1: free rotation
X: Center point of recess on end surface (diameter)
Z: Center point of recess on lateral surface
I: Recess depth and position
■ I>0: recess to right of reference element
■ I<0: recess to left of reference element
K: Recess width (without chamfer/rounding)
U: Recess diameter (diameter of recess floor) – use only if the
reference element runs parallel to the Z axis.
A: Recess angle – default: 0
■ with H=0: 0°
† A < 180° (angle between edges of recess)
■ with H=1: 0° < A † 90° (angle between reference straight and
recess edge)
B: Outside radius/corner. Starting point near corner - default: 0
■ B>0: Radius of rounding
■ B<0: Width of chamfer
P: Outside radius/corner. Starting point distant from corner - default: 0
■ P>0: Radius of rounding
■ P<0: Width of chamfer
R: Inside radius (in both corners of recess) – default: 0
The CNC PILOT refers the recess depth to the reference
element. The recess base runs parallel to the reference
element.
