Both the aerospace industry and the military industry are subject to strict specifications and standards regarding the design and construction of the parts and products used in their applications. For example, aerospace components must meet AS9100 standards, while military components must meet Mil-spec standards. These requirements and restrictions help ensure components will perform reliably and safely in critical situations or extreme conditions. For these reasons, aerospace and military OEM manufacturers often specify advanced manufacturing techniques and technologies—e.g., precision machining—to ensure the components they utilize fully meet strict guidelines.
Precision machining is an umbrella term covering many high-precision subtractive manufacturing processes (i.e., processes that remove material from the workpiece to create the desired component), including CNC Swiss machining. Compared to other manufacturing methods, there are many advantages to using precision machining to produce aerospace and military components, such as:
