SolidCAM is a market leader in integrated CAM (Computer-Aided Manufacturing) solutions, renowned for its seamless integration with SOLIDWORKS and its revolutionary iMachining technology. However, even the most powerful toolpath strategy is useless without one critical translator: the . A Post Processor (or “Post”) is the bridge
A Post Processor (or “Post”) is the bridge between SolidCAM’s virtual G-code and your specific physical CNC machine (Haas, Mazak, DMG Mori, Tormach, etc.). Without a correct post, your machine might crash, produce scrap, or simply refuse to move.
