Resetting; Positioning The Axes Of Rotation - HEIDENHAIN TNC 620 User Manual

WORKING PLANE (Cycle 19, DIN/ISO: G80, software option 1) 11.9

Resetting

To cancel the tilt angle, redefine the WORKING PLANE cycle and
enter an angular value of 0° for all axes of rotation. You must then
program the WORKING PLANE cycle once again and respond to
the dialog question with the NO ENT key to disable the function.

Positioning the axes of rotation

The machine tool builder determines whether Cycle
19 positions the axes of rotation automatically or
whether they must be positioned manually in the
program. Refer to your machine manual.
Manual positioning of rotary axes
If the rotary axes are not positioned automatically in Cycle 19, you
must position them in a separate L block after the cycle definition.
If you use axis angles, you can define the axis values right in the L
block. If you use spatial angles, then use the Q parameters Q120
(A-axis value), Q121 (B-axis value) and Q122 (C-axis value), which
are described by Cycle 19.
For manual positioning, always use the rotary axis
positions stored in Q parameters Q120 to Q122.
Avoid using functions, such as M94 (modulo rotary
axes), in order to avoid discrepancies between
the actual and nominal positions of rotary axes in
multiple definitions.
