CAD/CAM system Hypermill

Annina Schopen,

Additive and subtractive processing simultaneously

At Formnext, Open Mind will be presenting the benefits of the Hypermill CAD/CAM system for users of additive manufacturing processes. The Best Fit concept will also be explained: a technique for reducing the effort involved in post-processing.

Hypermill Additive Manufacturing opens up the possibilities of 5-axis simultaneous machining for the Direct Energy Deposition (DED) process and Wire Arc Additive Manufacturing (WAAM). NC codes can be programmed and automatically simulated to avoid collisions. As an end-to-end software solution, this enables efficient hybrid machining with additive and subtractive machining on one machine.

Support structures and surfaces that show the layered structure make it necessary to finish additively manufactured workpieces during machining. Except when using hybrid machines, post-processing requires the alignment of an almost finished raw part with a small allowance in the machine tool. With Hypermill Best Fit, Open Mind replaces time-consuming and error-prone manual alignment with an automatic process. Instead of positioning additively manufactured parts for post-processing in the milling machine so that the zero point and axes match the NC code, Best Fit adapts the code to the real position of the workpiece in the machine's workspace, which is imported as a digital twin via measurement and simulation.
