Rotary table dynamic fixture offset
The rotary table dynamic fixture offset function saves the operator the
trouble of resetting the workpiece coordinate system when the rotary table
rotates before cutting is started. With this function the operator simply sets
the position of a workpiece placed at a certain position on the rotary table as
a reference fixture offset. If the rotary table rotates, the system
automati-cally obtains a current fixture offset from the angular displacement
of the rotary table and creates a suitable workpiece coordinate system. After
the reference fixture offset is set, the workpiece coordinate system is
prepared dynamically, wherever the rotary table is located.
The zero point of the work piece coordinate system is obtained by adding the fixture offset to
the offset from the work piece reference point.
