Chapter Three Programming

Part 1 Programming
If the movement amount from point A to D is increment, the D’ becomes an object point on the
programmed path, and the conversion point D’ becomes point E, and the tool moves to the point E
Y
, because
only Y axis is specified.
* Absolute
If the point D is absolute, tool moves to the point E which is converted by the point D.
(b) Cancel the presetting operation by setting the BIT3 CLER of parameter 007.
G51 turns into G50, if the movement command is increment, the tool moves to the point D’ (refer to the
Fig. A). If the movement command is absolute, the tool moves to the point D (refer to the Fig. B).
3.6.8 Coordinate system rotation (G68, G69)
The specified figure can be rotated in program by this function. For example, the workpiece is
installed rotating the programmed position to a certain angle position, namely, the specification of
rotation command can be modified using the coordinate rotation function. Additional, in the rotation
mode program of a similar figure, this program can be called as a subprogram of the coordinate
rotation. So that, the program time and program length can be shortened.
