Page 65: Crosshair Probe Data Collection Parameters
Specifying Collection Parameters Crosshair probe data collection parameters Data collection parameters for crosshair probes include: • Crosshair timeout delay • Motion distance Crosshair timeout delay When the auto-enter function is enabled during feature measure- ment on the LCD Video screen, a point is collected by the sys- tem each time the stage is moved to position the part under the crosshair.
Page 66: Edge Probe Data Collection Parameters
QC-300 Series User’s Guide Edge probe data collection parameters Data collection parameters for edge probes include: • The number of points to be collected for lines, circles and arcs by the multiple edge probe • Edge timeout delay Number of points probed for a line, circle and arc When the multiple edge probe is used, the probe is seeded with a small number of points to define the feature type, and then the remaining points are collected automatically by the system.
Page 67: Collecting Feature Data
Specifying Collection Parameters Collecting feature data Feature data can be collected manually by positioning a probe over a part feature and pressing the Enter key, or collected automatically by enabling the auto-enter function and using the multiple edge probe. Manual probing with crosshairs is useful when part edges are indistinct and feature edge contrast is poor. Automatic probing can acquire many points simultaneously and increases productivity when feature edge boundaries are clear and automatic point entry is possible.
Page 68: Crosshair Probes
QC-300 Series User’s Guide Crosshair probes The crosshair probes consist of two lines crossed at 90 degrees in the video window. Probing is identical for straight and offset crosshairs. Single points can be acquired manually or automatically. Straight crosshairs Offset crosshairs Manual probing (crosshairs) Disable auto-enter for manual probing.
Page 69: Automatic Probing (Crosshairs)
Probing Automatic probing (crosshairs) The process of probing automatically with crosshairs is identical to probing manually with crosshairs except that the user does not press the Enter key to enter points. Enable auto-enter for manual probing. To probe part features automatically: Select the feature to be measured.
Page 70: Single Edge Probe
QC-300 Series User’s Guide Single edge probe The single edge probe consists of a standard crosshair with a small circle at the center for positioning the edge detector. Single points can be acquired manually or au- tomatically. Manual probing (single edge) Disable auto-enter for manual probing.
Page 71: Automatic Probing (Single Edge)
Probing Automatic probing (single edge) The process of probing automatically with the single edge probe is identical to probing manually with the single edge probe except that the user does not press the Enter key to enter points. Enable auto-enter for manual probing. To probe part features automatically: Select the feature to be measured.
Page 72: Multiple Edge Probe
QC-300 Series User’s Guide Multiple edge probe The multiple edge probe consists of a standard crosshair with two small concen- tric circles at the center for positioning the edge detector. Points will be probed manually for some features as they are when the single edge probe is used, and automatically for line, circle and arc features when the probe is seeded.
Page 73: Probing A Line
Probing Probing a line The same basic technique is used to probe a line whether the line is completely within or outside the field of view. To probe a line using the multiple edge probe: Select the Line feature measurement, and then select the multiple edge probe. Seed the multiple edge probe at the two extreme ends of the line.
Page 74: Probing A Circle
QC-300 Series User’s Guide Probing a circle Two techniques can be used to probe a circle using the Multiple edge probe. The first technique is that described earlier for probing lines and arcs and can be used to probe a circle whether the circle is com- pletely within or outside the field of view.
Page 75 Probing The second technique can only probe a circle located within the field of view that is large enough to enclose the center of the Multiple edge probe, but the technique is extremely simple and productive. To probe a circle using the second technique with the multiple edge probe: Select the Circle feature measurement, and then select the multiple edge probe.
Page 76: Probing An Arc
QC-300 Series User’s Guide Probing an arc The same basic technique is used to probe an arc whether the arc is completely within or outside the field of view. To probe an arc using the multiple edge probe: Select the Arc feature measurement, and then select the multiple edge probe. Seed the multiple edge probe at 3 points in sequence from the beginning to the end...
Page 77: Seeding To Avoid Erroneous Data

This is accomplished by: Seeding points very close to, and enclosing the area of anomaly using the single edge probe Switching to the multiple edge probe to complete the measurement by probing the reminder of specified points automatically Normally, the multiple edge probe attempts to collect the specified number...
Page 78: Recovering From Data Errors
QC-300 Series User’s Guide Recovering from data errors Data errors are rare when the part, stage and optical system are clean and well maintained, and the lighting, contrast and brightness are properly adjusted. In addition, the QC-300 is extremely forgiving of typical cleanliness and lighting issues.
Page 79 Probing When the operator elects to continue probing the remaining points, the green arrow points to each missing point which is signified by a large X. When the stage is moved to position the single edge probe and arrow at the X and the Enter button is pressed, the next missing point is shown and the green arrow points to it. When all the remaining missing points are entered, the Finish key is pressed to complete the measurement and store the feature data in the Feature list.

Page 81 Chapter 6: Measuring Measurements can be conducted using video edge detection probes or using crosshairs. Measurements can be limited to probing feature points, or can include the construction or creation of new features in addition to probing. However measurements are conducted, the fundamental measurement process and the tools required to perform measurements remain unchanged.
Page 82: Measurement Activities
QC-300 Series User’s Guide Measurement activities QC-300 measurement sessions can include one or all of the following activities: • Establishing a measurement reference • Constructing features • Probing and measuring features • Creating features The measurement process The basic measurement process shown here is identical for all feature types. The details of individual measurement steps are described in the remaining pages of this section.
Page 83: Establishing The Measurement Reference
The Measurement Process NOTE When video probes are used, the stage and optical system must be well maintained, free of scratches and other damage and clean. The optical magnification and part lighting must be prepared as described in Chapter 5: Probes. Establishing the measurement reference A reliable measurement reference must be established before part features can be probed and measured.
Page 84: Skewing The Part
Finish key to complete the level measurement. The level plane feature will be added to the Features list in blue. The four corners of the Metronics quickie slide are probed to perform part leveling Skewing the part When the part is misaligned (twisted) in the X-Y plane, errors can be generated during the measurement process.

Page 89: Probing And Measuring Features
Probing and Measuring Features Probing and measuring features Part features are measured by creating a part datum, and then by probing points that define the feature’s shape and location. Feature points can be probed using Measure Magic or by using a specific measure- ment function such as the line or circle function.
Page 90: Probing Specific Feature Types
QC-300 Series User’s Guide Probing specific feature types When measure magic is not used a measure icon must be touched before each specific feature type is probed. However, a series of features of the same type can be probed by touching the desired measure icon and then touching multiple measurement icon.
Page 91: Probing Process
Probing and Measuring Features Probing process The feature probing process is essentially the same for all feature types. Touch the desired measure icon Probe and enter features, then press Results are displayed in the Finish to complete measurements Video, DRO and View windows Supported feature types The following feature measurements are supported by the QC-300: •...
Page 92: Backward/Forward Annotation
QC-300 Series User’s Guide Backward/forward annotation Forward annotation is used to specify a required number of probed points for each feature type. Backward annotation allows the user to probe any number of points beyond the minimum requirement for any feature type.
Page 93: Probing Specific Feature Types
Probing and Measuring Features Probing specific feature types While the probing process is essentially the same for all feature types, the minimum number of points required and the geometric placement of these points are different. The unique requirements for probing each feature type are described in the remainder of this section.
Page 94: Probing Lines
QC-300 Series User’s Guide Probing lines A minimum of two probed points is required to measure a line. There is no practical limit to the number of points that can be probed, and in general accuracy is increased by probing more points. Three points are probed to measure a line When only two points are probed, Measure Magic will correctly recognize a line and assign the correct feature.

Page 155: Chapter 7 Tolerancing
Chapter 7: Tolerancing Tolerances can easily be applied to position, size, orientation, form, runout and concentricity measure- ments using the tools found in the tolerance screens. CAUTION Discrete point measuring machines estimate the size, position, orientation, and form of geometric features based on points probed. When parts are designed with critical tol- erances, be sure that you have probed sufficient points to calculate a reliable estimate.

QC-300 Series User’s Guide Tolerances The following information is supplemental to the tolerance discussions provided earlier in Chapter 7: Tolerancing. Concentricity tolerance The mathematical definition of concentricity is explained in detail in the ASME Y14.5M-1994 standard and involves “the midpoints of opposing elements” in the determination of actual concentricity. This is not practical in a discrete point measuring system, so the QC-300 uses the center of the feature (determined by the best fit) to estimate the concentricity.
