4.4 Contour Form Elements
Recess (general) G23-Geo
G23 defines a recess on the previously programmed linear reference
element. The reference element can also be oblique.
Parameters
H Type of recess (default: 0)
0: Symmetrical recess
1: Relief turn
X Center point of recess on the face (diameter)
No input: Position is calculated
Z Center point of recess on the lateral surface
No input: Position is calculated
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: Angle between recess edges (0° <= A < 180°)
H=1: Angle between reference line and recess edge (0° < A
<= 90°)
B Outside radius/chamfer at corner near the starting point
(default: 0)
B>0: Rounding radius
B<0: Chamfer width
P Outside radius/chamfer at corner far from the starting point
(default: 0)
P>0: Radius of the rounding arc
P<0: Chamfer width
R Inside radius in both corners of recess (default: 0)
BE, BF, BD, BP and BH (see “Machining attributes for form
elements” on page 181)
The MANUALplus refers the recess depth to the
reference element. The recess base runs parallel to the
reference element.
