Meaning:
Trigger for intermediate block:
Corner rounding with:
G641
G642
G643
G644
TLIFT block with:
linear movement of tangential axis and without lift
motion
nonlinear movement of tangential axis
(polynomial) and without lift motion
lift movement, tangential axis movement and lift
movement start simultaneously
lift movement, tangential axis does not start until
certain lift position is reached.
Path segmentation:
programmed path segmentation is active without
punching or nibbling
programmed path segmentation with active
punching or nibbling
automatically, internally generated path
segmentation
Compile cycles:
ID of the compile cycle application that generated
the block
