GLLM is an innovative system that converts natural language instructions into executable G-code for CNC machines, dramatically simplifying the programming process for manufacturing.

Key Innovations:

• Fine-tuned StarCoder-3B model specifically trained for G-code generation
• Implements Retrieval-Augmented Generation (RAG) to access domain-specific knowledge
• Incorporates user feedback loops for self-correction and improvement
• Bridges the gap between human-readable instructions and machine-executable code

Engineering Impact: By automating a traditionally manual and error-prone process, GLLM reduces programming time, minimizes errors, and makes CNC machining more accessible to operators with limited G-code expertise.
