This lockstitch sewing machine demonstrator was designed by the Luxxo CAD AI from an engineering-challenge request. It has 38 parts, measures 280 × 124 × 229 mm and weighs 9.7 kg, in steel S235. Below you can read the request, the main specifications and the problems the AI flagged, and download the STEP, STL, DXF and A3 drawing for free.

The request

“Design a cutaway mechanical demonstrator of a single-needle lockstitch sewing machine.”

Flagged by the AI

  • The 0.1 mm hook-to-needle clearance is tighter than the general tolerance, so the hook and needle seat need IT6 machining and shim adjustment.
