Qualifiers
There are seven potential qualifiers used in GPP2 linear motions.
Basic feed-rate linear motions blocks come with no qualifier. Most of the rapid motions come with the fast: qualifier (except cutter length compensation, see below).
Four qualifiers are provided for cutter compensation purposes. They should be used to turn cutter compensation on and off (if relevant to a given procedure).
-
normappr: Normal approach to a contour
-
normretr: Normal retract from a contour
-
ltangappr: Before a tangential approach to a contour
-
ltangretr: After a tangential retract from a contour
There are two cutter length compensation (G43) qualifiers:
-
fastlencomp: Rapid motion where cutter length compensation should be applied
-
lencomp: Feed-rate motion, for the same purpose (see rapid to feed)
GPP2 generates the cutter length compensation as part of the connection process from the safe position (typically takes place after tool change).
Recall the two-level hierarchy regarding linear motions qualifiers:
fastencomp à fast à none
If a block is invoked with the fastlencomp: and the exact block cannot be found in the program, GPP2 will attempt to execute the block with the fast: qualifier. Only if that block is missing too, GPP2 will execute the LINEAR MOTION block with no qualifier.
From Cimatron 2024, there are two new qualifiers for LINEAR MOTION block.
-
Linpausing:
-
Fastpausing:
The LINEAR MOTION block with these qualifiers contains the motions to and from the pausing point, when the function is set to only replace inserts and not for the entire tool.
