You can specify the distribution of points in a probe path using the following parameters:
Points — The Points parameter specifies the number of points to be probed, distributed evenly around the feature.
You can change the number of Slices and Points by incrementing and decrementing the count values in the Parameters dialog.
For features such as lines, slots and rectangles, the UseMargin parameter specifies a Margin between the boundary of the feature and the locations of the probe points. To change the margin, click the box and overtype the current value.
To probe the feature without a margin, deselect the UseMargin check box.
Pitch — The Pitch parameter specifies the distance between points around the circumference of the feature. To increase the point density, enter a smaller Pitch value.
Chordal — The ChordalTolerance parameter controls the number of probe points by specifying the maximum distance that a chord between two probe points can be from the circumference of a circle.
To increase the point density, enter a smaller ChordalTolerance value.
HeadTouch Moves — The HeadTouchMoves method is designed for probe heads that support head-touch moves, such as REVO. It is optimized to take points using the rotary axes of the probe head. For example, this method enables the head to pivot and rotate to take each point inside a circle while the machine remains static.
The following examples show how different calculation methods affect probe paths for a circle:
