Stud

The Stud tool measures the location and radius of a stud.

The tool does not search for or detect the feature. The tool expects that the feature, conforming reasonably well to the defined parameters, is present and that it is on a sufficiently uniform background.

The tool uses a complex feature-locating algorithm to find a hold and then return measurements. See "Stud Algorithm" in the Gocator Measurement Tool Technical Manual for a detailed explanation of the algorithm. The behavior of the algorithm can be adjusted by changing the parameters in the measurement panel.

The location of the stud is defined at either the stud tip or the stud base. The tip is the intersection of the stud axis and the top of the stud; the base is the intersection of the stud axis and the surrounding plane.

The stud shape is defined by the tip height and base height. The base and tip heights specify where the shaft with the nominal radius begins and ends.

Measurements, Features, and Settings

Measurements
Measurement	Illustration
Tip X Determines the X position of the stud tip.
Tip Y Determines the Y position of the stud tip.
Tip Z Determines the Z position of the stud tip.
Base X Determines the X position of the stud base.
Base Y Determines the Y position of the stud base.
Base Z Determines the Z position of the stud base.
Radius Determines the radius of the stud.

Features
Type	Description
Tip Point	The center point of the tip of the stud.
Base Point	The center point of the base of the stud.

For more information on geometric features, see Geometric Features.

Parameters
Parameter	Description
Source	The sensor, or combination of sensors, that provides data for the tool's measurements. For more information, see Source.
Stud Radius	Expected radius of the stud.
Stud Height	Expected height/length of the stud.
Base Height	The height above the base surface that will be ignored when the (truncated) cone is fit to the stud data.
Tip Height	The height from the top of the surface that will be ignored when the (truncated) cone is fit to the stud data.
Region	The region to which the tool's measurements will apply. For more information, see Regions.
Reference Regions	The tool uses the reference regions to calculate the base plane of the stud. Reference regions are relative to the base of the stud.
Tilt Correction	Tilt of the target with respect to the alignment plane. Autoset: The tool automatically detects the tilt. The measurement region to cover more areas on the surface plane than other planes. Custom: You must enter the X and Y angles manually in the X Angle and Y Angle parameters (see below).
X Angle Y Angle	The X and Y angles you must specify when Tilt Correction is set to Custom. You can use the Surface Plane tool's X Angle and Y Angle measurements to get the angle of the surrounding surface, and then copy those measurement's values to the X Angle and Y Angle parameters of this tool. For more information, see Plane.
Radius Offset (Radius measurement only)	The distance from the tip of the stud from which the radius is measured.
Filters	The filters that are applied to measurement values before they are output. For more information, see Filters.
Decision	The Max and Min settings define the range that determines whether the measurement tool sends a pass or fail decision to the output. For more information, see Decisions.

Anchoring
Anchor	Description
X, Y, or Z	Lets you choose the X, Y, or Z measurement of another tool to use as a positional anchor for this tool.

A measurement must be enabled in the other tool for it to be available as an anchor. The anchor measurement should also be properly configured before using it as an anchor.

For more information on anchoring, see Measurement Anchoring.

Measurement Region

The tip and the side of the stud must be within the measurement region.
