Meso-machining of miniature space system components

Many industries in engineering and science are focusing more on producing mechanisms and system components of magnitudes smaller than existing products. One of the major technologies associated with these demands is the development of meso scale precision manufacturing systems. Meso scale fabrication involves the scaling down of conventional machining to incorporate the use of familiar materials, such as aluminum, steel, and even titanium for machining miniature components. New techniques in meso scale fabrication allow for the machining of miniature space system components in an efficient manner to meet certain specifications. A description of the processes used to accurately machine a complex turbo pump assembly as well as an experimental injector nozzle is given. Specific issues involved with the machining of these scaled down components are also addressed in detail. The surface finish of each pump component is also analyzed to develop methods of improvement.
