Conventions & Terms QC-300 refers to any of the QC-300 series of instruments. [. . . ] This reference will be created by the user and ensures a level part surface, precise part alignment and a coordinate origin or datum zero. Reference features are presented in the feature list in blue, other features are presented in black. Leveling the part (optional) When the surface plane of the part is not orthogonal to the measurement axis, small cosine errors can be generated during the measuring process. Additionally, if the depth of field of the lens system is not much less than the level error, no benefit can be gained from leveling the part. 6 Measuring To level the part: 1 TouchtheMeasureSkewiconandthentouchtheMeasureLevelicon. 54 QC-300 Series User's Guide 2 TouchtheLeveliconandperformthelevelingmeasurementbyprobingthreeormorepointsthatare well distributed across the surface of the desired part plane. Use the Crosshair to probe, move the Z-axis of the stage to focus the part surface under the Crosshair and then press the Enter key to enter each point. The level plane feature will be added to the Features list in blue. The four corners of the Metronics QC 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. These errors can be eliminated by creating a skew alignment for the part. The skew alignment includes a precise measurement of the part misalignment. Once the misalignment is known to the system, subsequent feature measurements are automatically compensated to eliminate misalignment errors. Measurement data in the DRO will reflect measurements of a perfectly aligned part. To skew the part: 1 Touch the Measure Skew icon. Establishing a Measurement Reference 2 Perform the skew alignment by probing 2 or more points well distributed along the entire length of the desired part reference edge. The skew line feature will be added to the Features list in blue. Two points are probed on the bottom edge to perform a skew alignment on the X-axis 55 Creating a datum zero point Creating the datum zero point is the final step in establishing a valid Cartesian or polar coordinate system for subsequent measurements. The datum zero point will be used as the origin of Cartesian or polar systems. The datum zero point can be positioned in any location that satisfies the measurement requirements of the user and can be created by probing a point or by constructing a point from parent features. Probing a datum zero point The datum zero point can sometimes be created directly by probing a point. Simple probing is more often possible when the part is precisely aligned in the stage. To probe a datum zero point: 1 Touch the Measure Point icon. 6 Measuring 2 Use the crosshair to probe the desired point for the datum zero, and then press the Finish key. The point will be added to the Features list in blue. 56 QC-300 Series User's Guide 3 While the point feature is selected touch the X and Y axis Zero buttons to establish a datum zero at the probed point. Constructing a datum zero point The datum zero point can be constructed from parent features when simply probing the desired point is not practical. It would not be possible to provide a single description of this process for all measurement applications that require feature constructions to create a datum zero point. However, the concept illustrated by the following example and the construction techniques described later in this chapter can be used to construct a datum zero point for any measurement application. In this example, after the part skew is performed, a datum zero point is constructed at the intersection points of the X-axis along the bottom of the part (skew axis), and the Y-axis along the left side of the part. To construct the datum zero point: 1 Touch the Measure Magic or theMeasureLineicon. Establishing a Measurement Reference 2 Probe two or more points well distributed along the left side of the part, and then press the Finish button. The line feature will be added to the Features list. 57 3 Touch the Measure Point icon, and then touch each of the two lines in the feature list to checkmark them. 4 Press the Finish key to complete the point construction. 6 Measuring 5 While the constructed point is selected, touch the Zero buttons of the X and Y axes to define the point's location as the zero datum. [. . . ] As you're troubleshooting, list the steps that you use to identify and solve your problem. Should problems persist in spite of your efforts, gather the product information listed at the end of this chapter, and your list of troubleshooting steps, and then contact your distributor for assistance. NOTE Confirm that the essential setup steps described in Chapter 10: Setup have been performed before troubleshooting or requesting assistance. 220 QC-300 Series User's Guide Symptoms, probable causes and solutions Some common symptoms of problems are listed in the following pages with probable causes and possible solutions.
