When manual movement is made along the Z-axis:
(1) A movement is made in the Z direction.
(2) A movement is made in the Z direction.
Fig.13.9 (c) Manual Operation during Three-dimensional Coordinate
Conversion
In manual feed, the same time constant, FL feedrate, and
acceleration/deceleration method as that for the cutting mode are used
for the three axes selected in three-dimensional coordinate conversion.
In manual rapid traverse, the same time constant, feedrate, and
acceleration/deceleration method as that for programmed rapid
traverse (positioning by G00) is used. When manual movement is
made during three-dimensional coordinate conversion, the tangent
feedrate in the coordinate system after conversion (program coordinate
system) is the lowest feedrate among those along the selected axes.
- Absolute position display
The absolute coordinates based on the program or workpiece
coordinate system can be displayed in the three-dimensional coordinate
conversion mode. Specify a desired coordinate system in the DAK bit
(bit 2 of parameter 2204).
NOTE
To enable absolute position display in three-
dimensional coordinate conversion, set bits 2 and 3
(DTL and DCR) of parameter No. 2202 to 0.
