A Practical Calibration Checklist

Four situations

Tool frame calibration (required after every tooling change), workpiece or user frame calibration, relative calibration between cooperating robots, and hand-eye calibration for vision.

Verify after calibrating

Check against a known point or master part, confirm the deviation is within tolerance, and record the date and result.

Common mistakes

Too few calibration points, no record after calibration, and forgetting to recalibrate after changing fixtures.
