4.5.3 Contour Form Elements
Recess (Standard) G22 Geo
Recess on a paraxial reference element (G1). G22 is assigned to the
previously programmed reference element.
Parameters
X:
Starting point of recess on the face (diameter)
Z: Starting point of recess on the lateral surface
I, K: Inside corner
■ I – recess on face: Recess end point (diameter value)
■ I – recess on lateral surface: Recess base (diameter value)
■ K – recess on face: Recess base
■ K – recess on lateral surface: Recess end point
Ii, Ki: Inside corner – incremental (pay attention to sign!)
■ Ii – recess on face: Recess width
■ Ii – recess on lateral surface: Recess depth
■ Ki – recess on face: Recess depth
■ Ki – recess on lateral surface: Recess end point (recess
width)
B: Outside radius/chamfer (at both ends of the recess) – default: 0
■ B>0: Radius of rounding
■ B<0: Width of chamfer
R: Inside radius (in both corners of recess) – default: 0
Continued
Program either ”X” or ”Z”.
4.5 Geometry Commands
Recess (general) G23-Geo
Recess on a linear reference element (G1). G23 is assigned to the
previously programmed reference element. On the lateral surface, the
recess can be positioned on an inclined reference straight.
Parameters
H:
Recess type – default: 0
■ H=0: Symmetrical recess
■ H=1: relief turn
X: Center point of recess on the end face (diameter)
Z: Center point of recess on the 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 base) – 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)
