7.10 G112 PROGRAMMING IN IMAGINARY CO-ORDINATES

Function G112, used to program on the front surface, transforms the real co-ordinates into imaginary co-

ordinates.

The imaginary axes are obtained by interpolating real axes X and C. Therefore with G112 active, the

control calculates the feed and the points needed to move the real axes along the imaginary components

X C.

It therefore results that every movement of imaginary X and C moves the two real axes.

Example of work trend in imaginary co-ordinates:

Function G112 is programmed in a block without any other instructions.

In imaginary co-ordinates G112 the co-ordinates of C are radial whereas the co-ordinates of X are

diametrical.

NOTE: After function G112 has been activated no further rapid traverses are allowed (G0), the origin

cannot be moved(from table G54-G59 and program G52) and no corrector change is allowed
