I’m looking to develop a focused CAM application that generates reliable multi-axis toolpaths for CNC mills. My priority is toolpath generation rather than full 3D modeling or high-end simulation, so the core of the work is an engine that can: • Import common CAD formats (STEP, IGES, or STL). • Let me define cutters, holders, and basic machining parameters. • Produce collision-aware 4- and 5-axis roughing, finishing, and drilling paths. • Post-process to standard G-code for popular controllers (Fanuc, Haas, Siemens, etc.). • Offer a simple UI—or command-line interface—where I can load a part, pick strategies, and export code. I’d like a functional prototype that I can run on Windows, macOS, or Linux—cross-platform via C++/Qt, Python, or a similar stack is fine as long as it stays performant with larger models. If you have experience integrating open-source kernels like OpenCascade, CGAL, or using libraries such as libfive or OCC’s CAM add-ons, let me know; leveraging them to speed things up is welcome. Deliverables: 1. Executable prototype with installer or clear build instructions. 2. Source code in a clean repository with comments. 3. Sample project files showing a successful multi-axis program from import to G-code. 4. Brief user guide covering workflow and any dependencies. I’m happy to iterate on strategy selection and post-processor tweaks along the way. If this initial phase goes well, we can extend the project to include simulation or more advanced optimization later.
