Case study

Reverse Engineering Sewing Machine

This project started with a damaged sewing machine and required reconstructing the system geometry, identifying missing parts, and producing a complete CAD-based mechanical assembly. The final SolidWorks model integrated recreated components and restored kinematic compatibility across the mechanism.

The brief

Challenge

The source hardware was incomplete and damaged, so geometry and interfaces had to be inferred while preserving realistic mechanical behavior.

Approach

What we made

I documented the physical system, recreated missing components in CAD, and constrained the full assembly iteratively until movement and part relationships were consistent.

  • Reverse engineered the machine from physical hardware condition and known component interfaces.
  • Modeled missing components and integrated them into a full assembly tree.
  • Validated the final CAD assembly for mechanical fit and working motion relationships.

Outcome

Results

Produced a complete SolidWorks assembly that represented a mechanically functional version of the original machine, including reconstructed missing parts.
