HEIDENHAIN TNC 426 B, TNC 430
Positioning an axis of rotation
Define the angle for calculation of the compensation
Activate compensation for the tool axis
Activate compensation for the working plane
Cancellation
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 by answering the
dialog question with the NO ENT key to disable the function.
Positioning an axis of rotation
The machine tool builder determines whether Cycle 19
positions the axes of rotation automatically or whether
they must be pre-positioned in the program. Your
machine manual provides more detailed information.
If the axes are positioned automatically in Cycle 19:
■
The TNC can position only controlled axes
■
In order for the tilted axes to be positioned, you must enter a
feed rate and a set-up clearance in addition to the tilting angles,
during cycle definition.
■
You can use only preset tools (with the full tool length defined in
the TOOL DEF block or in the tool table)
■
The position of the tool tip as referenced to the workpiece
surface remains nearly unchanged after tilting
■
The TNC tilts the working plane at the last programmed feed rate.
The maximum feed rate that can be reached depends on the
complexity of the swivel head or tilting table.
If the axes are not positioned automatically in Cycle 19, position
them before defining the cycle, for example with an L block:
Example NC blocks

L X+25 Y+10 R0 FMAX
L A+15 R0 F1000
