HIGH SPEED CONTACT DETECTOR FOR MEASUREMENT SENSORS |
| 摘要 |
A workpiece is measured by a contact detector. The contact detector is moved relatively towards a workpiece. A characteristic of the contact detector that changes as the contact detector contacts the workpiece is measured at a plurality of times. A projected time when the characteristic of the contact detector will meet a predetermined threshold is extrapolated from the characteristic measured the plurality of times and using a processor of a computer. A trigger is set to measure coordinates of the workpiece at the projected time. Coordinates of the workpiece are measured at the projected time based on the set trigger. |

1. A method of measuring a workpiece using a contact detector, comprising:
moving the contact detector relatively towards a workpiece; measuring at a plurality of times a characteristic of the contact detector that changes as the contact detector contacts the workpiece; extrapolating, from the characteristic measured the plurality of times and using a processor of a computer, a projected time when the characteristic of the contact detector will meet a predetermined threshold; setting a trigger to measure coordinates of the workpiece at the projected time, and triggering a measurement of coordinates of the workpiece at the projected time based on the set trigger. |
