High-Volume Cost-Saving Nano-Precision Stamping of Metal Fuze S&A Components

This proposal describes a Phase II program that will result in a nano-precision manufacturing process to produce low-cost US ARMY S&A Fuze components at high-volume. This technology will be used to design and develop for manufacturability the MEMS Safe and Arm Arming Slider and/or Frame and associated manufacturing process. nanoPrecision Products is pioneering the development of a nano-precision stamping process for metal components with a goal of ± 100 nm form tolerances by combining deterministic micro-grinding (DMG) with computerized modeling, metrology, and optimization of fundamental process materials and mechanics – no such capability exists today. The nanoPrecision Products approach includes development of the key factors and technologies necessary for forming tooling and tooling systems, as well as development of the design of progressive dies, and validation of both die geometry and tooling system through FEA and CAE. Finally, a statistically significant number of S&A MEMs Arming Slider and/or Frame physical parts will be presented to the Army at the end of the contract.
