Researchers have demonstrated a technique that allows people who manufacture metal machine parts with 3D printing technologies to conduct automated quality control of manufactured parts during the finishing process.
The technique allows users to identify potential flaws without having to remove the parts from the manufacturing equipment, making production time more efficient.
After a metal machine part is printed, it requires additional finishing and has to be measured to ensure the part meets critical tolerances. In other words, every aspect of the part must be the right size. Currently, that involves taking a part out of the relevant manufacturing equipment, measuring it, and then putting it back into the manufacturing equipment to make modest adjustments.
To test the performance of the new approach, researchers manufactured a machine part using conventional 3D printing and finishing techniques, and then manufactured the same part using their new process. "All of the hardware we used in this technique is commercially available, and we outline the necessary software clearly in the paper -- so we feel that this new approach could be adopted and put into use almost immediately," McConnell says."And we are certainly open to working with partners who are interested in making use of this technique in their operations."Chicago
