Detailed description
2.4 Frames
2.4.7.2 Additive frame in frame chain
Measurements on the workpiece or calculations in the part program and cycles generally
produce a frame that is applied additively to the current complete frame. The WCS and thus
the programming zero must, therefore, be displaced and possibly rotated. This measured
frame is available as a temporary frame and not yet actively included in the frame chain. This
function is used to calculate and possible activate this frame:
INT ADDFRAME(FRAME,STRING)
Programming
Parameter 1:
Parameter 2:
Function value:
The ADDFRAME() function calculates the target frame, which is specified by the STRING.
The target frame is calculated in such a way that the new complete frame appears as a
chain of the old complete frame and the transferred frame, e.g.:
ERG = ADDFRAME(TMPFRAME,"$P_SETFRAME")
