SURFACE MEASUREMENT APPARATUS AND METHOD
A stylus is deflected as a tip of the stylus follows surface variations along a measurement path on a surface of a workpiece. A transducer provides measurement data in a measurement coordinate system. A data processor is configured to: determine a relationship between the data in the measurement coo...

| description | A stylus is deflected as a tip of the stylus follows surface variations along a measurement path on a surface of a workpiece. A transducer provides measurement data in a measurement coordinate system. A data processor is configured to: determine a relationship between the data in the measurement coordinate system and nominal surface data representing the expected surface characteristic of the workpiece in a workpiece coordinate system; simulate a measurement data set for the nominal surface using the nominal surface data and the determined relationship; if a simulated range of the simulated data set does not meet a given criterion, adjust a selected measurement data value for a selected point and repeat the simulation to determine an adjusted data value for which the simulated range meets the criterion; and determine start conditions required for a measurement procedure to provide the adjusted data value for the selected measurement point. |
