HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 23)

HEIDENHAIN CNC PILOT 4290 23
2.3.2 Positioning Moves
Rapid traverse G0
The tool moves at rapid traverse along the shortest path to the
”target point X, Y, Z.”
Parameters
X, Y, Z: Target point (X diameter)
2.3 G Functions for Machining
Before you program the Y axis for a milling operation with linear or
circular movements or with fixed cycles, you must first define the
working plane.
If no working plane is programmed, the CNC PILOT assumes a
turning operation or a milling operation with the C axis (G18 XZ
plane).
Drilling
Drilling with the Y axis operates as with the C axis (see User's Ma-
nual, section ”4.8.11 Drilling Cycles”).

of
Working
Planes
2.3.1 Working Planes
G17 XY plane (front or back)
Milling cycles are executed in the XY plane, with the depth feed for
milling and drilling cycles in the Z direction.
G18 XZ plane (for turning operations)
In the XZ plane, ”normal turning operations” as well as drilling and
milling operations are executed with the C axis.
G19 YZ plane (side view/surface)
Milling cycles are executed in the YZ plane, with the depth feed for
milling and drilling cycles in the X direction.
Milling
The milling cycles G840, G845 and G846 are used
for C axis and Y axis machining (see User's Manual,
section ”4.8.15 Milling Cycles”).
The milling cycles G841, G842, G843, G844 are
also available for milling operations. These cycles
and G845/G846 are described below.
Programming X, Y, Z: Absolute,
incremental or modal
