Auto Feature dialog box - Cylinder
To measure a cylinder with a laser sensor:
Access the Auto Features dialog box and select Cylinder.
From the Inner/Outer box, choose In or Out.
Do one of the following:
Perform clicks on the CAD to give the cylinder location and vector. Manually enter any remaining information.
Manually enter all of the theoretical information for X, Y, Z, I, J, K, Inner/Outer value, diameter, length, depth, and other parameters.
From the Graphic
Display window, use the Laser tab to move
the machine to the cylinder location. Next, from the Feature
properties area, click Read Point from Machine
. Manually enter
any remaining information, such as the Inner/Outer value, diameter,
length, and other parameters.
In the Measurement properties area, enter the Center Offset, Search Length, Start Angle, End Angle and Direction.
The Start Angle and End Angle properties are helpful when you need to measure fractions of a cylinder. This is especially so when:
The Start Angle and End Angle are already defined in the CAD.
The CAD model already defines a complete cylinder, but the actual pointcloud data is not complete.
The CAD model defines the Start Angle and End Angle the wrong way.
To define the Start Angle and End Angle properties, do one of these:
Learn them from the CAD model with a single click.
Use the dialog box to manually enter the values or use the spinners to increment or decrement the values.
You can edit the existing values and select the Direction value in the dialog box.
These parameters are then passed into PC-DMIS to extract the feature.
Enter the necessary information in the Probe Toolbox tabs. Cycle through the Laser Scan, Laser Filtering, and Laser Clipping properties tabs to enter the information.
If desired, click the Test button to test the feature.
WARNING: When you do this, the machine moves. To avoid injury, stay clear of the machine. To avoid hardware damage, run the machine at a slower speed.
Click the Create button and then Close.
The location and direction vector of the feature defines the center axis of the cylinder.
