GPU‑Accelerated Toolpath Simulation: Faster, Safer Manufacturing in Fusion

Experience revolutionary GPU simulation with the new GPU‑accelerated toolpath simulation in Fusion. Slash verification times from minutes to seconds for faster, safer manufacturing.

Elevate Your Design and Manufacturing with Autodesk Fusion

In computer‑aided manufacturing (CAM), GPU simulation is redefining how we verify toolpaths. Traditional CPU‑based simulations can take minutes—or even over 20 minutes on a high‑end Intel® i9‑12950HX—especially for complex, multi‑axis programs. This delay hampers iterative design, prolongs lead times, and can mask collision risks that lead to costly machine damage.

GPU‑based simulation harnesses the massive parallelism of modern graphics processors, turning hours of computation into seconds. Our new “Fast mode” feature, available on Fusion for Windows, delivers the following performance gains:

• With an NVIDIA RTX A1000 Laptop GPU, a complex program that previously required 23 minutes now verifies in under 15 seconds.
• Using a high‑end NVIDIA 4080 Super‑Ti GPU, verification completes in less than 10 seconds, and real‑time visualization occurs in under one second.

These speed improvements not only accelerate workflows but also empower engineers and machinists to iterate more freely, test advanced cutting strategies, and reduce material waste.

1. Speed: GPU acceleration dramatically shortens simulation times, enabling rapid verification and faster production cycles.
2. Efficiency: Fast, accurate simulations unlock new opportunities for innovation, allowing teams to refine toolpaths and optimize machining processes.
3. Scalability: Performance scales with GPU capability—higher‑end GPUs deliver even greater speed and flexibility.

The Future of CAM with GPU Simulation

Autodesk and the Fusion team continue to push GPU simulation to new heights, integrating speed, precision, and scalability into a single platform. This breakthrough is a pivotal step toward digital manufacturing that is faster, safer, and more efficient.
