I – 6 Programming POSITIP 880
Chamfer
A chamfer is an angled cut which connects two adjacent line blocks
within a program. The POSITIP 880 calculates the location of the
chamfer. The two lines do not have to intersect or touch, however, if
they do touch, the lengths are calculated from their intersection
points. See Fig. I.55 as a graphic example of a chamfer.
A chamfer usually connects the previous block in the program with the
next block to form a continuous path. It is also possible to have the
chamfer connect the previous block to the first block within the
current continuous path. This “closes” the path.
Intersecting lines – You can insert a chamfer between two
intersecting lines that are adjacent in the program sequence. See Fig.
I.54.
A chamfer step can be specified by:
8 Length 1 and length 2, the angle is blank.
8 Length 1 or length 2 and the angle.
