CELOS DYNAMICpost is computer software that integrates three functions: a post processor, machining simulation, and cutting force optimization. After converting a CAD/CAM-designed toolpath to an NC program on the post processor, the cutting simulation function uses DMG MORI digital twin technology to evaluate the machining shape, performs an interference check, and then estimates machining time. The cutting force optimization function evaluates the cutting load, and automatically generates an NC program with optimized machining conditions.
