Page 50 QC-300 Series User’s Guide...
Page 51 Chapter 6: Measuring Measurements can be performed using single-fixed, star, indexable or friction hard probes or touch probes. Activities can be limited to probing features, 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 52: Measurement Activities
QC-300 Series User’s Guide Measurement activities QC-330 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 53: Establishing A Reference Frame
Establishing a Reference Frame Establishing a reference frame A reliable measurement reference must be established before part features can be probed and measured. This reference frame is created by the user to ensure a level part surface, precise part alignment and ac- curate datum zero.
Page 54: Part Skew Alignment
QC-300 Series User’s Guide Part skew alignment 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 performing a skew alignment on 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.
Page 55: Establishing A Datum Zero Point
Establishing a Reference Frame Establishing a datum zero point The datum zero point is used as the origin of the reference frame. 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, but is probably better created by constructing a point from parent features.
Page 56 QC-300 Series User’s Guide Establish the zero datum point by touching the Zero buttons for the X and Y axes. The datum point will be shown in blue in the feature list and the X-Y values will be zero.
Page 57: Saving The Reference Frame
Establishing a Reference Frame Saving the reference frame Measurements are referred to a temporary reference frame until a new reference frame is saved. Temporary reference frames are indicated by a T in the reference frame icon in the upper-right corner of the screen, and by a T in the UCS (user coordinate system) field of the DRO.
Page 58: Saving Reference Frames Automatically
QC-300 Series User’s Guide Saving reference frames automatically The QC-330 can be configured to save reference frames automatically in the Measure setup screen, as described in Chapter 10: Setup. When configured to auto-save reference frames, the current reference frame is saved each time a new datum operation is initiated.
Page 59: Measuring Features
Measuring Features Measuring features Part features are measured after creating a reference frame by selecting a projection plane (if required) and then probing points that define the feature’s shape and location. Selecting a projection plane Projection planes can be selected by the user or selected automatically by the system and include: •...
Page 60: Probing Features
QC-300 Series User’s Guide Probing features Feature points can be probed using Measure Magic or by choosing a specific feature type such as the line or circle. Measure Magic or measure functions are selected by touching icons in the measure toolbar. Repeat- edly touching the measure tab toggles the measure toolbar between 2D and 3D functions.
Page 61: Probing Without Measure Magic
Measuring Features To probe a feature using Measure Magic, touch the Measure Magic measure icon (if not configured to auto-start), probe points on the desired feature and then press the Finish key. Probing specific feature types without Measure Magic When Measure Magic is not used, a measure icon must be touched before a feature type is probed. How- ever, a series of features of the same type can be probed by touching the desired measure icon and then touching the multiple measurement icon.
Page 62: Probing Process
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 the feature, then press Finish Results are displayed in the DRO to complete measurements and View screens Supported feature types The following feature measurements are supported by the QC-330: •...
Page 63: Backward/Forward Annotation
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 except slots and rectangles. When using forward annotation, the number of remaining required points is shown at the top left of the screen.
Page 64: 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 65: Probing Lines
Measuring Features Probing lines A minimum of two points are 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. When only two points are probed, Measure Magic will correctly rec- ognize a line and assign the correct feature.
Page 66: Probing Circles
QC-300 Series User’s Guide Probing circles A minimum of three probed points are 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. When 185 degrees or more of the circle is probed, Measure Magic will correctly recognize the circle and assign the correct feature.
Page 67: Probing Arcs
Measuring Features 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. When the arc is less than 185 degrees, Measure Magic will correctly recognize the arc and assign the correct feature.
Page 68 QC-300 Series User’s Guide Probing slots and rectangles Five probed points are required to measure a slot or rectangle. The five points must be probed in a clockwise or counterclockwise sequence. As shown here, the correct pattern of points probed is: •...
Page 69: Probing Angles
Measuring Features Probing angles A minimum of four probed points are required to measure an angle. The points must be probed as two lines that form an angle. The number of points on the first leg of the angle must equal the number on the sec- ond leg.
Page 70: Probing Distances
QC-300 Series User’s Guide Probing distances Two probed points are required to measure a distance. Measure Magic can not be used to measure a distance. Measurement results are shown in the Feature list, View screen, and the DRO screen. The View screen shows the feature and the points used to define it, the X and Y axis displacements the distance vector between features,...
Page 71: Probing Planes
Measuring Features Probing planes A minimum of three probed points are required to measure a plane. There is no practical limit to the number of points that can be probed, and in general accuracy is increased by probing more points. A best fit algorithm is used to define the plane when more than three points are probed.
Page 72: Probing Cylinders
QC-300 Series User’s Guide Probing cylinders A minimum of six probed points are required to measure a cylinder. The points must be probed beginning with two sets of three points; one set of three at the top and another at the bottom of the cylinder. After the initial six points, there is no practical limit to the additional number of points that can be probed, and in general accuracy is increased by probing more points.
Page 73: Probing Cones
Measuring Features Probing cones A minimum of six probed points are required to measure a cone. The points must be probed beginning with two sets of three points; one set of three at the top and another at the bottom of the cone. After the initial six points, there is no practical limit to the additional number of points that can be probed, and in general accuracy is increased by probing more points.
Page 74: Probing Spheres
QC-300 Series User’s Guide Probing spheres A minimum of four probed points are required to measure a sphere. The points can be probed in any order. After the initial four points, there is no practical limit to the additional number of points that can be probed, and in general accuracy is increased by probing more points.
Page 75: Constructing Features
Constructing Features Constructing features Features can be constructed from one or more existing features. Existing features used to construct new features are called parent features, and can be features that were measured, constructed or created. Exist- ing features are shown in black, and constructed features are shown in blue in the View screen. Feature constructions are divided into seven categories: •...
Page 76: Extracted Features
QC-300 Series User’s Guide Extracted features Features such as points and lines can be extracted from parent features. In this example, an axis line is extracted from a cone. Select the line feature type... select the parent cone feature... then press the Finish key Intersection features Features such as points, lines and circles can be constructed from the intersections of positional, linear and plain features.
Page 77: Relation Features
Constructing Features Relation features Features such as angles and distances can be constructed by relating one linear feature to another or one positional feature to another. In this example, an angle is constructed between two lines. Select the line feature type... select the two plane features...
Page 78: Perpendicular/Parallel/Tangent Features
QC-300 Series User’s Guide Perpendicular/parallel/tangent features Line features can be constructed that are perpendicular, parallel or tangent to other linear or positional features. In these examples, a line is constructed through a point that is perpendicular to another line and a line is constructed that is tangent to two circles.\ Perpendicular line example Select the line feature type...
Page 79: Gage Line And Circle Features
Constructing Features Gage line and circle features Gage lines and circles can be constructed between to linear features. In this example, a gage line is constructed between two lines. When gage lines and gage circles are constructed, an extra step is required. The user must enter a gage line length or gage circle diameter.
Page 80: Creating Features
QC-300 Series User’s Guide Creating features Features can be created for any feature type by entering position, size and other parameters into feature data fields. The process for creating feature is identical for all feature types: Feature data fields are self-ex- planatory.
Page 81 Chapter 7: Tolerancing Tolerances can easily be applied to position, form, orientation, runout and size measurements 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 97: Chapter 8 Programming
Chapter 8: Programming QC-330 programs are sequences of measurement steps performed on a part by the operator and stored by the system for playback later on other identical parts. Using the programming capabilities of the QC-330 greatly increases productivity by compressing the many manual steps required to measure, tolerance and report part dimensions into a few guided steps which are little more than operator responses to system prompts.
