Programming technological functions (cycles)
10.6 Further cycles and functions
The retraction mode is modal. When a tool is changed or after a block search, the retraction
mode last set is used.
Risk of collision
You must select a retraction position that avoids a collision between the tool and workpiece
when swiveling.
Tool
To avoid collisions, you can use the 5-axis transformation (software option) to define the
position of the tool tip during swiveling.
● Correct
The position of the tool tip is corrected during swiveling (tracking function).
● No correction
The position of the tool tip is not corrected (not tracked) during swiveling.
Swivel plane (only for G code programming)
● New
Previous swivel frames and programmed frames are deleted and a new swivel frame is
formed according to the values specified in the input screen.
Every main program must begin with a swivel cycle with the new swivel plane, in order to
ensure that a swivel frame from another program is not active.
● Additive
The swivel frame is added to the swivel frame from the last swivel cycle.
If several swivel cycles are programmed in a program and programmable frames are also
active between them (e.g., AROT ATRANS), these are taken into account in the swivel
frame.
If the currently active WO contains rotations, e.g., due to previous workpiece measuring
operations, they will be taken into account in the swivel cycle.
