GibbsCAM is an automated CNC program preparation system that combines ease of use with powerful functionality. The system’s core functionality can be expanded by adding specialized modules. The intuitive user interface provides easy access to functions for managing geometry, tools, toolpaths, verification, and post-processing. Flexible programming methods allow you to quickly create optimal machining programs. Optimized machining processes can be saved and reused using the knowledge base. Simulation features help prepare geometry for machining by creating wireframe, surface, and solid geometry. The built-in material removal simulation accurately depicts the entire machining process, showing both the change in workpiece geometry over time and all possible collisions. The simulation results can be compared with the original model geometry to identify material residues or undercuts. Full associativity between geometry, process parameters, and toolpaths allows you to quickly modify the model and machining parameters and automatically generate updated toolpaths.
