- Changing the workpiece origin offset
This function can change the workpiece origin offset of an individual
axis of the workpiece coordinate system corresponding to G54 to G59
or G54.1P1 to P48 specified during automatic operation. There is a
currently valid workpiece coordinate system even in a reset state. So,
axis movement made by manual feed causes the workpiece origin
offset of that workpiece to be changed. In addition, movement along
any axis (regardless of axis types, such as basic three axes, parallel axes,
and rotation axes) can change the workpiece origin offset. Moreover,
manual feed can be made along more than one axis at a time, when the
workpiece origin offset is being changed.
Example
Assume the following conditions:
- Specified workpiece coordinate system: G56
- G56 workpiece origin offset (X-axis): 50.000
- G56 workpiece origin offset (Y-axis): -60.000
- G56 workpiece origin offset (Z-axis): 5.000
- G56 workpiece origin offset (A-axis): 5.000
- G56 workpiece origin offset (B-axis): 15.000
- Amount of manual feed-based movement along
the X-axis: -10.000 mm
- Amount of manual feed-based movement along
the Y-axis: -5.000 mm
- Amount of manual feed-based movement along
the Z-axis: 10.000 mm
- Amount of manual feed-based movement along
the A-axis: 8.000 mm
- Amount of manual feed-based movement along
the B-axis: -2.000 mm
Under the above conditions, the workpiece origin
offset for G56 is changed as follows:
- X-axis : 50.000 + (-10.000) = 40.000
- Y-axis : -60.000 + (-5.000) = -65.000
- Z-axis : 5.000 + 10.000 = 15.000
- A-axis : 5.000 + 8.000 = 13.000
- B-axis : 15.000 + (-2.000) = 13.000
