Description

Accurate in-situ measurement of part dimensions during fabrication is of much interest to the manufacturing industry for process automation [1]. This work addresses one such application, with a specific goal to make precise on-line thickness measurements on thin metal parts of rotation: hemispherical shells 100 to 200 mm in diameter. Current manufacturing practice prevents monitoring the thickness before final inspection is performed at a separate metrology station. With the shells held in place by a vacuum chuck in a turning center, part access is restricted to one side for in-process monitoring, suggesting the ultrasonic technique for the measurement.
