Positioning In A Tilted Coordinate System; Combining Coordinate Transformation Cycles - HEIDENHAIN TNC 620 User Manual

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

Positioning in a tilted coordinate system

With the miscellaneous function M130 you can move the tool,
while the coordinate system is tilted, to positions that are
referenced to the non-tilted coordinate system.
Positioning movements with straight lines that are referenced to
the machine coordinate system (blocks with M91 or M92) can also
be executed in a tilted working plane. Constraints:
Positioning is without length compensation.
Positioning is without machine geometry compensation.
Tool radius compensation is not permitted.

Combining coordinate transformation cycles

When combining coordinate transformation cycles, always make
sure the working plane is swiveled around the active datum. You
can program a datum shift before activating Cycle 19. In this case,
you are shifting the machine-based coordinate system.
If you program a datum shift after having activated Cycle 19, you
are shifting the tilted coordinate system.
Important: When resetting the cycles, use the reverse sequence
used for defining them:
1. Activate the datum shift
2. Activate tilting function
3. Activate rotation

1. Reset the rotation
2. Reset the tilting function
3. Reset the datum shift
