2.4.8.2 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 )
Parameter 1:
Parameter 2:
Function value
The ADDFRAME() function calculates the target frame, which is specified by the STRING.
The target frame is calculated such that the new complete frame comprises a chain of the
old complete frame and the transferred frame, e.g.:
ERG = ADDFRAME( TMPFRAME, "$P_SETFRAME" )
The new complete frame is calculated to be:
$P_ACTFRAME

Type: FRAME
Type: STRING
Type: INT

; 0: OK
; 1: Specified target (string) is wrong
; 2: Target frame is not configured
; 3: Rotation in frame is not permitted
