1.0 Overview
The goal of this application is to detect the various types of chamfers on the piston rings. To achieve the following results we used a highly diffused backlight mounted on an angle with the camera mounted directly over the ring. With this setup we were able to create enough contrast between the chamfered edge and the top surface to be able to reliably detect whether or not a chamfered edge was present.
We have received samples for the following types of rings:
ID – Inside top chamfer
IR – Inside top chamfer
2X – No chamfer present
R – No chamfer present on our samples (verified this under a microscope even though the documentation states there is an inside top edge chamfer. Can you please verify this?)
2.0 Images and Results
Figure 1 – Non-Chamfered edge
Notice the check marks on the left of the window. The system placed a green check mark next to the non-chamfered edge.
2.0 Images and Results (continued)
Figure 2 – Chamfered Edge present
Notice the check marks on the left of the window. The system placed a green check mark next to the text “Chamfered Edge”.
3.0 Conclusion
Based on our test with the limited samples we feel that this will be a robust application using the method we have described. We would need additional samples of the other types of chamfers to complete the application review. If you have any questions don’t hesitate to contact me.
