HEIDENHAIN CNC PILOT 4290 235
The CNC PILOT refers the recess depth to
the reference element. The recess base
runs parallel to the reference element.
Recess type D (sealing ring)
This recess type defines an axial or radial recess on the outside or
inside of the contour. The recess is assigned to the previously
selected reference element.
Parameters
X:
Starting point for radial recess
Z: Starting point for axial recess
I: Diameter/radius of recess base
Ii: ■ Axial recess: Recess depth
■ Radial recess: Recess width (pay attention to sign!)
Ki: ■ Axial recess: Recess width (pay attention to sign!)
■ Radial recess: Recess depth
B: Outside radius/chamfer (at both recess sides)
■ No: no chamfer/rounding
■ Chamfer: B = width of chamfer
■ Rounding: B = radius of rounding
R: Radius at bottom (inside radius in both recess corners)

Recess general
Recess general defines an axial or radial recess on a linear reference
element.The recess is assigned to the selected reference element.
Parameters
X/Z:
Reference point
K: Recess width (without chamfer/rounding)
I: Recess depth
U: Diameter/radius of recess base (for recesses parallel to the
Z-axis)
A: Recess angle (angle between recess edges) –
0° † A < 180°
P: Outside radius/chamfer (corner far from starting point)
■ No: no chamfer/rounding
■ Chamfer: P = width of chamfer
■ Rounding: P = radius of rounding
B: Outside radius/chamfer (corner near starting point)
■ No: no chamfer/rounding
■ Chamfer: B = width of chamfer
■ Rounding: B = radius of rounding
R: Radius at bottom (inside radius in both recess corners)
