HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 48)

Y Axis 48
Single hole
”Datum” parameter
XM(X), YM(Y): Hole center in Cartesian coordinates (X radius
dimension)
α, PM: Hole center in polar coordinates (reference of angle α : posi-
tive X axis)
The ”hole” can contain the following elements:
■ Centering
■ Core drilling
■ Sinking
■ Thread
Hole description:
”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
4.1.2
Contours
in
the
XY
Plane
(Front
and
Back)
Circle (complete circle)
Parameters
XM(X), YM(Y): Center in Cartesian coordinates (XM radius
dimension)
α, PM: Center in polar coordinates (reference angle α : positive X
axis)
K: Circle diameter or radius
P: Depth of the figure
”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.
