Procedure for working with Cycle G80 WORKING PLANE
1. Create program
• Define the tool (not required when TOOL.T is active).
• Call the tool.
• Retract the tool in the tool axis to a position where there is no
danger of collision with the workpiece (clamping devices) during
tilting.
• Position the tilt axis or axes with a G00 block to the appropriate
angular value(s).
• Activate datum shift if required.
• Define Cycle G80 WORKING PLANE; enter the angular values for
the tilt axes.
• Traverse all main axes (X, Y, Z) to activate compensation.
• Write the program as if the machining process were to be executed
in a non-tilted plane.
• Reset Cycle G80 WORKING PLANE; program G80 without entering
tilt axes.
• Reset datum shift if required.
• Pre-position the tilt axes to the 0° position if required.
2. Clamp workpiece
3. Preparations in the POSITIONING WITH MDI mode
Preposition the tilt axis/axes to the corresponding angular value(s).
The angular value depends on the selected reference plane on the
workpiece.
4. Preparations in the MANUAL OPERATION mode
Use the 3D-ROT soft key to set the function TILT WORKING PLANE
to ACTIVE in the MANUAL OPERATION mode; enter the angular
values for the tilt axes into the menu (see page 2-26).
The angular values entered in the menu must correspond to the actual position(s) of the tilted axis or axes,
respectively. The TNC will otherwise calculate a wrong datum.
5. Set datum
• Manually by touching the workpiece with the tool in the non-tilted
coordinate system (see page 2-7)
• Automatically by using a HEIDENHAIN 3D touch probe
(see page 2-14)
6. Start part program in the PROGRAM RUN/FULL SEQUENCE mode
7. MANUAL OPERATION
Use the 3D-ROT soft key to set the function TILT WORKING PLANE
to INACTIVE. Enter an angular value of 0° for each tilt axis into the
menu (see page 2-26).
