PROGRAMMED PATH
To program a 1/2 circle, combine two //_
1/4 circle commands.

(7) When programming G45 to G48, only 01 group G codes (GO0, G0I, G02, G03) can be
programmed. G-code programming other G01 group causes the alarm state.
(8) In the incremental designation mode (G91), since only the motion for the offset is
required, program "0" for movement.
G91 G01 G45 X0 Y0 D10F ...;
The machine moves through the offset distance corresponding to D10 in both the X-
and Y-axes directions.
G91 G00 G46 X0 Dll;
The machine moves only in the X direction through the offset of Dll in the minus
direction.
Giving a sign to "0" is meaningless.
NOTE
1. When G45 to G48 are programmed to effect simultaneous motions on
two axes, the extension or redUction is effective along both axes. If this
is applied to a cutting tool, an overcut or undersize cut will result. This
requires careful attension. See Fig. 4.21.
2. This X, Y position offset can be programmed in addition to the Z-axis
position offset.
3. When G92 isprogrammed in the offset mode, the coordinate system
setting process is executed after the cancellation of the offset in the
designated axis. In principle, specify G92 after restoring the offset
position by programming a reverse offset.
4. Execute a return-to-reference point command after cancelling this
command.
