Fast Probing Considerations for On-Machine Inspection of Parts



Alice V. Ling, Neil D. Wilkin


A calibration procedure for on-machine probing is developed. This is necessary if the machine is used as a coordinate measuring machine to measure the absolute part dimensions. This is most crucial in turning machines where the turret is unable to go below the centerline of the part. However, in measurements on turning centers and machining centers where a differential measurement can be achieved on a feature, calibration is not as crucial. On-machine-probing variables, such as the feed rate at which probing occurs, have a proportional relationship to effective errors in the timing of the probe triggering system. Experiments were performed to verify and model machine feed rate during probing with resulting systematic measurement error.
