CNC Code Generation for Manufacturing
Language model for automated generation of CNC machine control programs.
Challenge
A major manufacturing enterprise was spending significant time on manual development of CNC machine control programs. Each part required custom code accounting for geometry, material properties, and equipment constraints. Human error led to defects, and qualified process programmers were in short supply.
Solution
A language model trained on technical documentation and engineering drawings automatically generates CNC machine control code. The system accounts for part geometry, material properties, tolerances, and specific equipment constraints. Generated code undergoes automated verification before being sent to the machine.
Results
Technologies
Approach
Technical documentation collection and structuring
Digitizing drawings, specifications, and existing control programs to build the training dataset.
LLM training on control programs
Fine-tuning the language model on a corpus of G-codes with consideration for geometry and process constraints.
Code verifier development
Building an automated verification module to check generated code for tolerance compliance and safety.
Pilot and iterative improvement
Testing on a batch of parts, collecting feedback from process engineers, model refinement.
