Use Cycle 19 to define the position of the working plane—i.e. the position of the tool axis referenced to the machine coordinate system—by entering tilt angles. There are two ways to determine the position of the working plane:
- Enter the position of the rotary axes directly.
- Describe the position of the working plane using up to three rotations (spatial angles) of the machine-based coordinate system.
The required spatial angles can be calculated by cutting a perpendicular line through the tilted working plane and considering it from the axis around which you wish to tilt. With two spatial angles, every tool position in space can be defined exactly.
Note that the position of the tilted coordinate system, and therefore also all movements in the tilted system, are dependent on your description of the tilted plane.
If you program the position of the working plane via spatial angles, the control will calculate the required angle positions of the tilted axes automatically and will store these in the Q120 (A axis) to Q122 (C axis) parameters. If two solutions are possible, the control will choose the shorter path from the current position of the rotary axes.
The axes are always rotated in the same sequence for calculating the tilt of the plane: The control first rotates the A axis, then the B axis, and finally the C axis.
Cycle 19 becomes effective as soon as it has been defined in the NC program. As soon as you move an axis in the tilted system, the compensation for this specific axis will be activated. You must move all axes to activate compensation for all axes.
If you set the Program Run switch in the 3D ROT menu (Manual operation operating mode / Manual operation) application to active, the angular value entered in this menu is overwritten by Cycle 19 WORKING PLANE.
