Micromachining of medical device and diagnostic products often requires fabrication of multiple features on multiple surfaces of a single component. In order to present the work piece to the ablating laser beam, the part must be rotated and translated several times with high precision. Even for small parts this typically results in a cumbersome tooling design and a complicated motion system, adding to the mass needed to be moved. Such high-inertia systems cannot move very fast and this results in throughput loss and higher manufacturing costs.
The U.S. Patent Office recently granted Nashua, N.H.-based Resonetics a new patent (U.S. 9,132,585) “Laser Machining System and Method for Machining Three-Dimensional Objects from a Plurality of Directions.” According to the company, the patent addresses the challenge of switching quickly from one location on the work piece to another by moving the laser beam instead of rotating the work piece.
Beam movement can be enhanced by using small galvo-driven mirrors in the path of the beam. This method replaces the costly scan lens with an inexpensive set of simple lenses. The tooling for this new method need only hold the part steady in one position, making it simpler, lighter and more economical, company officials said.
“The technical team at Resonetics has developed a novel solution to address unmet customer needs for quality, speed and cost-effectiveness,” said Tom Burns, CEO. “This is just the latest example of listening to our customers and finding innovative ways to solve their manufacturing problems.”
