Vericut 7.3 CNC software from CGTech includes enhancements that significantly improve performance and simplify the process of simulating a CNC machine. Changes to how users interact with Vericut improve the workflow. Vericut enables users to eliminate the process of manually proving out NC programs, thus reducing scrap loss and rework. The program also optimizes NC programs to save time and produce a higher quality surface finish. It simulates CNC machine tools from manufacturers such as DMG-Mori Seiki, Mazak, Makino, Matsuura, Hermle, DIXI, and Chiron. Vericut runs stand-alone but can also be integrated with CAM systems such as Catia, NX, Creo Parametric (Pro/E), MasterCAM, PowerMill, EdgeCAM, hyperMILL, Esprit, and GibbsCAM. Compared to the previous version, collision checking speed is at least 5-10x faster when the NC program moves the simulated machine into potential collision conditions.
