reference element.
Parameters
Z:
Starting point of recess
Ki:
Recess width (pay attention to sign!)
I:
Diameter/radius of recess base
Ii:
Recess depth
B:
Outside radius/chamfer (at both recess sides)
■
No: no chamfer/rounding
■
Chamfer: B = width of chamfer
■
Rounding: B = radius of rounding
Relief turn (form FD)
This recess type defines an axial or radial relief turn on a linear
reference element. The relief turn is assigned to the previously
selected reference element.
Parameters
X/Z:
Reference point
K:
Recess width
I:
Recess depth
U:
Diameter/radius of recess base (provided that the recess
base is parallel to the Z-axis)
A:
Recess angle ( 0° < A <= 90° )
R:
Inside radius in both corners of the recess
The CNC PILOT refers the recess depth to the reference
