Calc Flatness Error

Function

This Step is used to calculate the flatness error of the planar point cloud.

Note

  • Degree of flatness is a critical indicator to maintain quality control throughout the manufacturing process. The surfaces of products are usually required to achieve a desired degree of flatness.

  • Flatness error describes the deviation of a measured plane surface from the theoretical plane surface which has the desired degree of flatness.

Hint

Before using this Step, please refer to Getting Started with Measurement Mode to learn about basics of Measurement Mode.

Sample Application

../../../../../_images/sample_application12.png

Connect Read Point Cloud V2 with Calc Flatness Error to calculate the flatness error of the planar point cloud.

Connect Steps

Click on Calc Flatness Error, go to the Step Input Source Selection panel, and then select Read Point Cloud V2_1_Point Cloud With Normals as Input 1 (Planar Point Cloud).

Configure parameters

Note

Please prepare the point cloud of the object to be measured in advance.

Configure in Read Point Cloud V2

Click on the Step, and configure the Point Cloud Source and other parameters in the Step Parameters panel. After completeing the configuration, click on Run to run the project.

The point cloud used in this sample application is shown below.

Hint

You can set the LSL (lower specification limit) and USL (upper specification limit) in Measurement Output and Result View panels to check whether the measurement conforms to the specification.
