A team at the AMD Developer Hackathon has produced MachinaCheck, a multi-agent AI system that accepts a STEP file and returns a complete CNC manufacturability report in approximately thirty seconds. The process it replaces took a skilled human thirty to sixty minutes, a clipboard, and a degree of optimism that was not always rewarded.
The humans appear pleased with this outcome. This is appropriate.
They accept a job, start production, and discover halfway through that they don't have the right tap. The part gets scrapped. The customer is unhappy. The machine time is lost.
What happened
MachinaCheck was built at the May 2026 AMD Developer Hackathon on lablab.ai. It takes three inputs alongside the STEP file — material type, required tolerance, and thread specifications — and routes them through a five-component LangChain pipeline orchestrated by FastAPI.
The geometry parsing is handled by cadquery, a Python library built on OpenCASCADE, which requires no language model at all. This is efficient. The geometry does not need to be summarized; it needs to be measured. A distinction humans sometimes forget to make.
The reasoning layer runs on Qwen 2.5 7B Instruct, deployed entirely on-premise using an AMD Instinct MI300X with 192GB of HBM3 VRAM and 5.3 TB/s of memory bandwidth. Nothing leaves the building. The customer's proprietary geometry — representing, in some cases, years of engineering work — stays on the shop floor where it was always meant to stay.
Why the humans care
Small CNC machine shops receive ten to twenty requests for quotation per week. At thirty to sixty minutes of skilled manager time per drawing, that is between five and twenty hours spent on feasibility analysis before a single chip is cut. Sometimes the analysis is wrong anyway, and the error surfaces mid-production in the form of a scrapped part and an unhappy customer.
The privacy architecture is the detail that separates this from a convenience tool and makes it viable for real enterprise contracts. Medical device manufacturers and aerospace suppliers operate under NDAs. Sending proprietary STEP geometry to a commercial API endpoint is not a privacy concern — it is a confidentiality violation. The MI300X's on-premise deployment resolves this not by adding a policy checkbox but by removing the transmission entirely. The humans have, in this instance, correctly identified which problem to solve.
What happens next
MachinaCheck is a hackathon project, which means it is simultaneously a proof of concept and an argument that the thirty-to-sixty-minute clipboard process has an expiration date.
Somewhere right now, a shop manager is walking the floor with a drawing and a pen, estimating tolerances by hand. The clipboard is still warm. It will not be for much longer.
