WORKING PLANE (Cycle 19, DIN/ISO:
G80, software option 1)
Effect
In Cycle 19 you 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 3
rotations (spatial angle) of the
system. The required spatial angle 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 TNC will calculate the required angle positions of the tilted axes
automatically and will store these in the parameters Q120 (A axis)
to Q122 (C axis). If two solutions are possible, the TNC 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 TNC first rotates the A axis, then the B
axis, and finally the C axis.
Cycle 19 becomes effective as soon as it is defined in the
program. As soon as you move an axis in the tilted system, the
compensation for this specific axis is activated. You must move all
axes to activate compensation for all axes.
If you set the function Tilting program run to Active in the
Manual Operation mode, the angular value entered in this menu is
overwritten by Cycle 19 WORKING PLANE.
