Knurl Inspection System for 155-mm Rocket-Assisted Projectile M549

The objective of his project was to design and fabricate a semi- automated, knurl inspection system to inspect the interface locking knurl surface on the 155-mm rocket-assisted motor body and warhead of the M549 projectile to the design parameters called out in the specifications. The system was designed to have adjustable limits for versatility and the ability to inspect at production rates. A General Automation 1645 computer for operation of the system was not included in the contract however, it was used for test and demonstration. The system has effectively demonstrated the application of the state-of-the-art electric optical technology to the inspection of artillery projectiles.
