The TwinCAT?3 function CNC Measurement is an optional package of CNC cycles that supports the measurement of tools or workpieces directly on the machine. The package consists of cycles for the calibration of the measuring system, for measuring the tool or for measuring the position and geometry of the workpiece: calibration cycles measuring probe measuring probe for tool measurement tool measurement length and radius calibrating workpiece zero point 1-, 2- and 3-point measurement circle measurement inner diameter/with 3 points/with obstacle outer diameter/with 3 points groove/gutter groove X/with obstacle groove Y/with obstacle gutter X/Y angle X/Y (C-axis) between 2 holes/tenons (C-axis) between hole and tenon (C-axis) between point in X and hole/tenon (C-axis) between point in Y and hole/tenon (C-axis) Z (A-/B-axis) rectangle measurement inside outside extra measurement 4 holes center of a pitch circle CS measurement manual/semi-automatic/automatic teach-in
