No Intersection Known
This feature of QuickPath Plus lets the programmer define two
intersecting, consecutive, linear paths without knowing the point at which
the actual intersection takes place. Both of these blocks must be linear
blocks and programmed in absolute mode. The angle of both of these
paths must be known.
This is done with a sequence of two linear blocks (in the current plane) in
which QPP calculates the end point of the first block. The start point of
the first block is the current axis position.
Important: The second block of these two blocks must be programmed in
absolute mode. Any attempt to program the second block in incremental
generates an error.
