8.7 Cycles for Coordinate Transformations
Coordinate transformations enable a programmed contour to be changed
in its position, orientation or size. The following coordinate transforma-
tion cycles are available:
7 DATUM SHIFT
Shift contours
8 MIRROR IMAGE
Mirror contours
10 ROTATION
.^
\
Rotate contours in the working plane
11 SCALING FACTOR
Increase or reduce the size of contours
The original contour must be identified as a subprogram or program
section.
Activation of coordinate transformations
Immediate activation: A coordinate transformation becomes effective as
soon as it is defined (it does not have to be called). The transformation
remains effective until it is changed or cancelled.
To cancel a coordinate transformation:
l
Define cycle for basic behavior with new values, such as scaling factor
1 .o
l
Execute miscellaneous function M02, M30 or END PGM block
(depending on machine parameter 7300)
l
Select a new program
