Precision machining with “Vision-in-the-Loop”

Precision machining is often associated with lengthy, highly sensitive, iterative processes, sometime prone to non converging accuracy.

Diamond turning with Dynamic Part Indexing®

For about 10 years, Wielandts UPMT have mastered precision diamond turning to reach sub-micron accuracy for the production of lens masters (incl. freeform) for various industries such as Automotive, Medical imagery, Virtual/Augmented Reality, …

Strong of their expertise, they have developed and patented a unique Dynamic Part Indexing (DPI®) technology allowing the precise manufacturing of high-density arrays of lenses on a single master without compromising on the individual lens nor complete array accuracy.

This unique system brings the best ultra-precision machining technique, i.e. on-axis diamond turning, to produce arrays of all kinds. By shifting the workpiece with respect to the main spindle in a dynamic, balanced and ultra-precise way, each surface of an array can be machined sequentially.

• surface finish
• and geometric freedom

Integrating Machine Vision in the manufacturing process

Beyond the intrinsic performance of the technology (freeform, low surface error, true 100% fill factor,…) Wielandts UPMTmake use of the Euresys Open eVision Libraries to introduce“Vision-in-the-loop”to their process and shorten the control-command cycle of their automated production facility.

Wielandts UPMT have picked among the wide range of Euresys libraries, the ones offering the possibility to capture, analyze and return the necessary parameters to the machining process in order to dynamically and on the fly drive the manufacturing process iterations.
