Teaching Video Edge Recognition Default edge detection parameters are adequate for most applications. However, poor contrast images can make multipoint probing with the edge detection probes difficult or impossible. The edge detection parameters can be changed to optimize probing. Please refer to the Manual Teach Procedure for the MeasureLogic Probe discussed earlier in Section 3: Probes for detailed instructions. Establishing a Reference Frame While a reference frame might be unnecessary for quick checks of part features in prototyping or similar environments, a reliable measurement reference must be established before part features can be measured as part of a formal manufacturing or inspection process. The M3 measurement reference frame can consist of: • Part leveling (a primary datum plane) • Skew alignment (secondary alignment) • Part Datum (measurement coordinate system origin) Part Leveling When the surface plane of a part is not orthogonal to the measuring axes, small cosine errors can be generated during the measurement process. These errors can be eliminated by leveling the part. NOTE This might not be required in most well-maintained systems. Additionally, for VED measurements, if the depth of field of the camera system is not less than the level error, no benefit can be gained from leveling the part. Part leveling of 15° or more is not permitted.
To measure a primary datum plane: 1 Select the desired probe from the probe menu.
Measure toolbar > Probe menu > Desired probe
2 Press the Datum Plane button of the Datum menu.
Measure toolbar > Datum menu > Datum plane button
3 Probe a minimum of three points evenly distributed across the surface of the part. Probing more than three points increases the accuracy of the measurement. 4 Press the Done button to complete the measurement and enter the datum plane into the Feature List. Measure toolbar > Done button NOTE Previously measured or constructed plane features can also be leveled by manually zeroing the theta angle coefficient and the Z position coefficient. Pressing the label buttons to the left of these coefficients in either the feature detail screen or the DRO viewports will set the corresponding values to zero.
