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:
