Sometimes they get it wrong. They accept a job, start production, and discover halfway through that they don't have the right tap or that their mill cannot hold the tolerance on a critical feature. The part gets scrapped. The customer is unhappy. The machine time is lost.

MachinaCheck is a multi-agent AI system. You upload a STEP file — the standard CAD format that customers send to machine shops — along with three simple inputs: material type, required tolerance, and any thread specifications. Thirty seconds later you have a complete manufacturability report telling you exactly whether you can make the part, what tools you need, what is missing, and what actions to take before starting production.

Before explaining the architecture, this point deserves its own section because it is not just a technical choice — it is a business requirement.

Manufacturing customers sign NDAs. Their STEP files contain proprietary geometry representing years of engineering work and millions of dollars in R&D. The hole pattern on a medical device or the pocket geometry on an aerospace component is confidential intellectual property.
