Full documentation ownership

The assignment covered the complete drawing package, translating an optical measurement concept into manufacturable system documentation.

System purpose

  • Scanned across a moving plastics-extrusion web without contact.
  • Used infrared measurement to evaluate thickness, composition, and uniformity.
  • Provided timely process information for production adjustment.
  • Integrated the scanner frame, optical head, electronics, controls, and line interfaces.

Engineering contribution

  • Developed the complete CADAM drawing set.
  • Documented optical-sensor packaging and mechanical interfaces.
  • Prepared parts and assemblies for manufacturing release.
  • Maintained consistency across the full documentation package.

Representative circa-1989 public-safe reconstruction. Exact optical paths, calibration methods, electronics, dimensions, and proprietary process interfaces are not reproduced.

Industrial spectroscopy

Placed precision infrared measurement into a working production-line instrument.

Complete release package

Connected parts, assemblies, interfaces, and drawing control into one manufacturing baseline.

Process value

Turned measurement data into timely production adjustment.
