The CNC PILOT
„ inserts the tool in the magazine,
„ takes the specified tool from the magazine,
„ moves to the tool change position,
„ tilts the B axis,
„ rotates the tool to the “normal” or “upside down” attitude (offset
position angle C),
„ calculates the tool data, taking the “orientation O,” the B axis
position and the position angle into account, and
„ adjusts the brake settings.
