Inspect Every Crankshaft, from the Forge to Final Wash

Add a real-time inspection layer to every crankshaft on the line with Roboflow vision AI for crankshaft inspection. Built for forge shops, machining lines, and engine plants where a fold from forging opens up after hardening, a grinding crack runs across a journal that already carries hours of machining, and a crack at an oil hole is the start of a fatigue failure in the field.

Forging and heat treatment:

Detect surface cracks and folds on forged blanks before machining, when scrapping a part costs the least.
Check for leftover flash, trim damage, and scale after trimming and shot blasting.
Flag cracks at section changes and oil holes after induction hardening.

Machining and grinding:

Inspect main and pin journals for grinding cracks, scratches, chatter, and burn marks after grinding and polishing.
Check oil holes for burrs, chips, and cracks at the hole edge.
Verify fillets, threads, keyways, and drilled features, alongside machined part inspection.

MPI, records, and traceability:

Read MPI indications under UV-A with automated magnetic particle inspection, and put each one in front of a certified inspector.
Keep an image for every crankshaft tied to its serial, with visual inspection traceability.
Trend findings by forging die, grinder, and shift, so a worn die or wheel shows up in the data before it shows up in scrap.

Bring intelligence to every crankshaft today. Stop forging and grinding defects from becoming scrap, rework, and engine failures in the field.

Frequently asked questions

What is crankshaft inspection with Vision AI?

Crankshaft inspection with Vision AI uses cameras at forging, machining, grinding, MPI, and final inspection and a trained computer vision model (opens in a new tab) to find cracks, folds, surface defects, and feature problems on every crankshaft, with an image record tied to its serial. It works with engine component inspection and, for cast iron crankshafts, casting defect detection.

Can Vision AI find fine cracks on ground journals?

Yes. Grinding cracks run as fine lines across the journal, perpendicular to the grinding direction. A detection or segmentation model trained on your own crankshaft images, with high-resolution cameras and lighting set up for the journal surface, picks those lines out against the ground finish, and tiling keeps hairline defects large enough to detect.

Does crankshaft inspection support IATF 16949, ISO 9001, and ASTM E1444?

Crankshaft inspection supports the inspection records and traceability expected under IATF 16949 (the automotive quality management standard) and ISO 9001 (the quality management system standard), and magnetic particle testing under ASTM E1444, with an image and result for every crankshaft.

Roboflow serves as the inspection engine, and your quality and NDT teams own the acceptance criteria, the written procedures, and the release decision.

Can it integrate with our line controls, MES, and quality systems?

Yes. Roboflow writes pass/fail and defect type to a PLC tag over OPC UA or MQTT, so the line can divert a crankshaft, and sends results and images over REST (opens in a new tab) or to a database for MES, SPC, and traceability systems.
