Page 49: Create Part Skew And Datum References
Measuring a Part Skew Create part skew and datum references 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.
Page 50: Create A Datum Zero Point
QC-300 Series User’s Guide Create 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 the measurement system. 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.
Page 51: Constructing A Datum Zero Point
Creating a Datum 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.
Page 52 QC-300 Series User’s Guide While the point feature is selected touch the X and Y axis Zero buttons to zero the values and establish a datum zero at the probed point. The point will then be shown in blue in the feature list.
Page 53: Measure A Feature

Page 61: Chapter 5 Probes
Chapter 5: Probes Measurements are conducted using crosshairs or (optional) optical edge detection. In either case, point entry can be manual or automatic. In addition, part probing can be entirely manual or assisted by programs that are prepared by the user. Crosshair and edge detection probes are described in this chapter.
Page 62: Probes
QC-300 Series User’s Guide Probes Edge detector and crosshair probes can be used to collect data points for feature measurements. Both probe types include manual and automatic point entry func- tions. Touch the Probe button icon to select a probe. Auto-enter optical edge detection Points are entered automatically when edges are crossed Manual optical edge detection...
Page 63: Automatic Point Entry
Probe Descriptions Automatic point entry When automatic point entry is used to measure features, the point is entered each time the stage is moved to position the part under the crosshair. The automatic point entry is delayed until the stage has been motionless for a short time after the move to ensure that the crosshair is located where the user intended.
Page 64: Preparing To Use Probes
QC-300 Series User’s Guide Preparing to use probes The accuracy and repeatability of measurements depend on the mechanical condition of the system, the condition of the part, system optics, lighting and calibration. System and part condition The measuring system is presumed to be undamaged and well maintained, which implies a recent calibra- tion, and a clean stage with acceptably small amounts of mechanical backlash.
Page 65: Calibration
Preparing to Use Probes Calibration Specification of encoder resolution is the first essential setup step explained in Chapter 10: Setup. NOTE All the essential setup steps described at the beginning of Chapter 10: Setup must be performed before conducting measurements. In some cases, it might also be necessary to perform error correction calibration to eliminate the effects of encoder and machine travel in accuracies.
Page 66: Probing With Edge Detectors
QC-300 Series User’s Guide Probing with edge detectors Points can be probed at light to dark or dark to light transitions using automatic or manual point entry. Automatic point entry To probe using edge detection and automatic point entry: 1 Select the auto point entry edge probe. 2 Teach the edge detector at the beginning of a measurement session, when lighting changes, when magnification changes or when other measurement conditions change.
Page 67: Manual Point Entry
Probing with Edge Detectors Manual point entry To probe using edge detection and manual point entry: 1 Select the manual point entry edge probe. 2 Teach the edge detector at the beginning of a measurement session, when lighting changes, when magnification changes or when other measurement conditions change.

Automatic point entry To probe using crosshairs and automatic point entry: 1 Select the auto point entry crosshair probe. 2 Touch the desired measure icon button and then position the cross- hair over the first target point.
Page 69 Chapter 6: Measuring Measurements can be performed manually or automatically (CNC option) using crosshairs or optional optical edge detection. Measurements can be limited to probing feature points, or can include the con- struction 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 70: Measurement Activities
QC-300 Series User’s Guide Measurement activities QC-300 measurement sessions can include two or more 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 71: Establishing The Measurement Reference
The Measurement Process NOTE When edge detection is used, the edge detection must be calibrated, and the optical system must be clean. The edge calibration is described in Chapter 5: Probes. Establishing the measurement reference A reliable measurement reference must be established before part features can be probed and measured. This reference will be created by the user and ensures a level part surface, precise part alignment and a coordinate origin or datum zero.
Page 72: Skewing The Part
QC-300 Series User’s Guide 2 Touch the Level icon and perform the leveling measurement by probing three or more points that are 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. Press the Finish key to complete the level measurement.
Page 73: Creating A Datum Zero Point

Page 76: Probing And Measuring Features
QC-300 Series User’s Guide 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 77: Probing Specific Feature Types
Probing and Measuring Features 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.

QC-300 Series User’s Guide 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 DRO Finish to complete measurements and View windows Supported feature types The following feature measurements are supported by the QC-300: • Points • Slots...
Page 79: Backward/Forward Annotation
Probing and Measuring Features 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 80: Probing Specific Feature Types
QC-300 Series User’s Guide 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 81: Probing Lines
Probing and Measuring Features 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. In this example, 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 82: Probing Arcs
QC-300 Series User’s Guide Probing arcs A minimum of three probed points is required to measure an arc. There is no practical limit to the number of points that can be probed, and in general accuracy is increased by probing more points. In this example, three points are probed to measure an arc When the arc is less than 185 degrees, Measure Magic will correctly recognize the arc and assign the cor- rect feature.
Page 83 Probing and Measuring Features Probing circles A minimum of three probed points is required to measure a circle. There is no practical limit to the number of points that can be probed, and in general accuracy is increased by probing more points. In this example, four points are probed to measure an circle When 185 degrees or more of the circle is probed, Measure Magic will correctly recognize the circle and assign the correct feature.

Page 143: 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.

Page 145: Applying Tolerances To Features
Applying Tolerances to Features Applying tolerances to features Tolerances are applied to feature measurements using tolerance screens. The method of applying toler- ances to features is diagrammed below and is nearly identical for all tolerance types. In the following example, a true position tolerance is applied to a circle feature. Selecting a feature Touch the desired feature in the feature list to select it.
Page 146: Selecting A Specific Tolerance
QC-300 Series User’s Guide Selecting a specific tolerance Touch the Tolerance menu title and then select the specific tolerance from the drop-down menu. The true position tolerance is selected in this example. Entering nominal, limit or tolerance values In this example, the Nominal and Tol Dia (Tolerance diameter around the nominal position) values are entered by touching the desired data fields and entering a new values using the number keys.

The following tolerances can be ap- plied to feature measurements: • Bidirectional • True position • MMC • LMC • Runout • Roundness • Concentricity • Straightness • Parallelism • Perpendicularity • Angle • Width...
Page 149: Circles And Arcs
Tolerance Types Circles and arcs The tolerance screens for circles and arcs are identical, and are used to specify the acceptable deviation from nominal positions in the X and Y axes, and from the nominal diameter or radius. The bidirectional tolerance compares the measured location of the center point of the arc or circle to the nominal center point and compares the measured diameter or radius to the nominal.
Page 150: True Position
QC-300 Series User’s Guide True position True position tolerances can be applied to points, lines, circles and arcs. Points and lines The tolerance screens for points and lines are identical, and are used to specify the acceptable deviation from the nominal feature position. The true position tolerance compares the measured location of the center point to the nominal center point.
Page 151: Mmc/Lmc (Material Condition)
Tolerance Types MMC/LMC (Material condition) MMC and LMC tolerances can be applied to bosses or to bores, compare measured center locations to the nominal centers and compare measured diameters to nominal diameters. MMC and LMC tolerances can be applied to circles and arcs. MMC Circles and arcs The MMC tolerance screens for circles and arcs are identical, and are used to specify the maximum mate- rial that can exist within a bore or on the surface of a boss.
Page 152: Lmc Circles And Arcs
QC-300 Series User’s Guide LMC Circles and arcs The LMC tolerance screens for circles and arcs are identical, and are used to specify the minimum material that can exist within a bore or on the surface of a boss. LMC tolerances can generate position bonuses as a result of size tolerance surpluses.
Page 153: Runout
Tolerance Types Runout Runout tolerances can be applied to circles and arcs. The tolerance screens are identical, and are used to specify the acceptable deviation from a circle or arc around the center of the Reference feature axis. Enter the acceptable position deviation into the Tol Zone data field and then enter the number of the reference feature for the runout toler- ance into the Ref Feature data field.
Page 154: Parallelism
QC-300 Series User’s Guide Parallelism Parallelism tolerances can be applied to lines and are used to specify the acceptable deviation from a line perfectly parallel to a Reference feature. Enter the acceptable parallelism deviation into the Tol Zone data field, and then enter the number of the reference feature for the Parallelism tolerance into the Ref Feature data field.
Page 155: Width
Tolerance Types Width Width tolerances can be applied to distances and are used to specify the acceptable deviation from a nomi- nal length. The length can be specified as a vector length (L) or as separate X, Y and Z lengths. Enter the allowed width lim- its into the Limit data fields as +/- ranges or as absolute limits. Touch the Limit data fields to toggle between +/- ranges or ab- solute limits.

Page 194: Slec Screen
QC-300 Series User’s Guide SLEC screen The SLEC screen contains fields for enabling and con- figuring linear error correction (LEC) or segmented linear error correction (SLEC) for each encoder axis. LEC or SLEC, which is right for my application? Any channel input device can include slight nonlineari- ties over its measurement range. LEC compensates for nonlinearities by applying a single linear correction value to the entire range of measurement. SLEC compensates for nonlinearities by applying correction values to the individual non linear segments of the measurement range.
Page 195 SLEC Screen Make sure the Enabled choice field is toggled to Off, and erase any existing data in all the data fields using the methods described earlier in this chapter. Station 0 should be displayed with zeros in the Standard, Observed and MZ Offset fields when this step is com- plete.
Page 196: Slec (Segmented Linear Error Correction)
QC-300 Series User’s Guide SLEC (Segmented linear error correction) SLEC compensates for encoder non-linearities by applying correction values to individual nonlinear seg- ments. These SLEC correction values are created by the QC-300 system using data provided by the user in the SLEC Setup screen. The SLEC setup data provided by the user consists of Standard (certified) and Observed (measured) values of a standard, or standards that cover the entire range of axis motion. The SLEC measurements can divide the axis range of motion into up to 150 segments. The example diagrammed on the next page shows standard values compared to observed values for 6 segments.
Page 197 SLEC Screen Make sure the Enabled choice field is toggled to Off, and erase any existing data in all the data fields using the methods described earlier in this chapter. Sta- tion 0 should be displayed with zeros in the Standard, Observed and MZ Offset fields when this step is complete.

Page 199: Nlec Screen
NLEC Screen NLEC Screen The NLEC screen contains fields for enabling and configuring nonlinear error correction (NLEC) for the X and Y encoder axes. Nonlinear error correction minimizes or eliminates the small inaccuracies in the X-Y measurement plane due to encoder linearity, mounting and ma- chine-travel imperfections. Error correction coef- ficients are obtained by measuring a certified cali- bration grid.
Page 200: Calibrating From Features
QC-300 Series User’s Guide Nonlinear error correction calibration can be performed using one of three methods: • Calibrate from features obtained by measuring the calibration grid using the QC-300. • Edit existing QC-300 calibration values if calibration adjustments are required. • Import calibration values (NLEC text file) collected earlier by measuring the calibration grid using a QC-5000. The first two methods listed above can use artifact calibration files (.acf files) to specify certified artifact calibration grid values.

Page 246: Tolerance Definitions
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.
