6 Coordinate calculation function
This function is for calculating the point group coordinates in one block.
Point groups are such as on a linear line, on a grid and on a circular arc.
By combining such functions as the canned cycle etc., drilling at each point group is available by
one command.
6.1 List of Coordinate Calculation Function
Table 6-1 List of coordinate calculation function
G code Name Function
G36 Bolt hole circle
Coordinate calculation of point group on
circular arc.
G37 Linear (angle)
Coordinate calculation of point group on linear
line by angle designation.
G38 Linear (X,Y)
Coordinate calculation of point group of linear
line by coordinate designation.
G39 Grid Coordinate calculation of point group on grid.

G39
X,Y: Reference point of coordinate calculation
I,J,K,P,Q: Coordinate calculation parameter
(1) Reference point coordinate (X,Y)
This should be commanded by the working coordinate system.
When this is omitted, the current position becomes the reference point.
(2) Coordinate calculation parameter (I,J,K,P,Q)
This should be commanded in the same block as the G36~G39.
This parameter is effective only in the block, and automatically cleared after calculation is
finished.
