 Accuracy data from the machine was combined with tool engagement information from the STEP-NC to predict the deflections, which were tested against actual machining results.In 2014, CAM data exchange using STEP-NC was shown at IMTS 2014 with daily machining demonstrations hosted by Okuma.A base machining process for a mold part was created by Boeing and then sent to Sandvik and ISCAR for optimization, producing a STEP-NC description containing all three process options.
