Test Semi-Dynamic Repeatability
Follow these steps to test semi-dynamic repeatability:
|
In semi-dynamic repeatability testing, the part is fixed in place using a fixture, and the robot, equipped with a camera, moves sequentially to the measurement positions of each feature on the part and takes photos. After completing one round of photo captures, the same operation is repeated to complete the remaining rounds. For example, if a part has 5 features, the semi-dynamic repeatability testing is performed as follows:
|
-
In the Configuration interface of Mech-Metrics, go to the Analysis and Compensation tab and click Dynamic Repeatability.
-
On the Dynamic Repeatability Testing page, select the part to be tested as the currently clamped part, choose the type as semi-dynamic, select the data source as real-time data, set the repeat times to 20, and then click Start Testing.
-
The recommended repeat times are between 20 and 50.
-
-
Run the robot program 20 times on the robot side.
-
After the testing is complete, view the test results on the right side of this page.
-
If an error occurs, follow the prompts provided by the software to troubleshoot.
-
In this software, the default semi-dynamic pass threshold is a repeatability range (R) ≤ 0.15mm. If the project has different pass threshold requirements, you can contact technical support for modifications.
