HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 55)

HEIDENHAIN CNC PILOT 4290 55
Single hole
”Datum” parameter
YM(Y), ZM(Z): Datum for drilling
The ”contour of hole” can include the following elements:
■ Centering
■ Core drilling
■ Sinking
■ Thread
”Centering” parameters
O: Centering diameter
”Core drilling” parameters
B: Hole diameter
P: Hole depth (depth of hole and countersink - without drill
point and center point)
W: Point angle
■ W=0°: Special meaning ”feed rate reduction (V=1)“
■ W>0°: Point angle
Fit: H6...H13 or ”without fit”
”Sinking” parameters
R: Countersinking diameter
U: Countersinking depth
E: Countersinking angle
4.1.3
Contours
in
the
YZ
Plane
(Side
View)
”Thread” parameters
I: Nominal diameter
J: Thread depth
K: Thread runout length
F: Thread pitch
Thread direction: Right-hand/left-hand
If you enter the ”point angle W=0°”, the
AWG generates a ”feed-rate reduction
(V=1)” during the drilling cycle.
Circle (full circle)
Parameters
YM(Y), ZM(Z): Center
Radius: Circle radius
K:
Circle diameter
P: Depth of pocket
