Mastercam 2026.R2 CAD/CAM Software Adds GPU-Accelerated Simulation

Mastercam 2026.R2 is a CAD/CAM software update introducing GPU-accelerated simulation and an AI-powered programming assistant, along with multiaxis and probing improvements.

GPU simulation reduces verification time significantly—in testing, a process that took nearly 90 minutes with CPU simulation completed in just over 22 minutes with GPU acceleration. Collision detection and material analysis run at the same accuracy as CPU-based verification.

Mastercam Copilot is an AI assistant that handles programming tasks via voice or text commands. It supports approximately 200 toolpath types and can adjust feed rates and spindle speeds across multiple operations, with confirmation prompts built in. It can also build complete machine groups based on verbal descriptions. A hands-free mode, activated by the keyword "Copilot," enables voice-controlled operation. Copilot also searches the myMastercam video library and returns results with timestamps linked directly to relevant training content.

Multiaxis updates include automatic tilting with bullnose endmills, improved 4-axis Swarf milling, smarter clearance plane calculations, and optimized level-based ordering.

This release adds support for Blum laser tool setters, enabling tool height offsets, wear checks, and breakage detection to be managed within the application. The integration is compatible with Fanuc, Siemens, Okuma, Heidenhain, Mazak, and Makino controls.

2026.R2 is available as a free update to customers on an active Mastercam CONNECT maintenance and support plan.
