The following options in the BASICSCAN dialog box (Insert | Scan | Circle) apply to this method. For more information about this dialog box and the circle basic scan, see "Performing a Circle Basic Scan".
Type
The Type list has these options:
IN: A hole
A
- Starting point
B - Initial vector
C - Angle
OUT: A stud
A
- Starting point
B - Initial vector
C - Angle
PLANE: A plane circle executed on the plane that the circle is lying on.
Angle
The Angle box displays the angle (in degrees to scan) from the start point. Both positive angles and negative angles can be used.
Positive angles are considered counterclockwise.
Negative angles are considered clockwise.
The CutVec is considered the axis about which the angle rotates.
Diameter
The Diameter box displays the diameter of the circle.
Depth
The Depth box displays the depth value that is applied against the CutVec direction. Both positive and negative values can be used.
If the circle has a center of 1.0,1.0,3.0, a CutVec of 0.0,0.0,1.0, and a depth of 0.5, the circle center is set to 1.0, 1.0, 2.5 during execution. If a depth of -0.5 is used for the same circle, the centroid is shifted to 1.0,1.0,3.5 during execution.
Conical Scan
The Conical scan check box allows for proper scan compensation on cones or spheres. This check box lets you scan more quickly when not perpendicular to the part surface. PC-DMIS continues to monitor the probe force as needed.
