Abstract
A calibration system and method for a multi-toolhead machine. A calibration device is installed onto the machine. When a first toolhead is calibrated with respect to the calibration device, based upon the change in position between the first toolhead and a predetermined reference on the calibration device, all of the remaining toolheads are automatically calibrated. The system is set up by calibrating each toolhead with respect to the calibration device and determining an offset between the calibrated position of each toolhead and the calibration of the first toolhead.
Claims26

- a multi-toolhead machine having a worktable,
- a calibration device having a predetermined reference installed on the worktable,
- a number one toolhead having a first adjustment variable relative to the predetermined reference, and
- a calibration program whereby a plurality of toolheads on the multi-toolhead machine are calibrated based on the first adjustment variable.
