Final answer:
High-speed machining (HSM) is a machining technique used on the UH-60M helicopter to improve efficiency and part quality. It involves using high spindle speeds and feed rates to remove material at a faster pace.
Step-by-step explanation:
High-speed machining (HSM) is a machining technique that involves using cutting tools with high spindle speeds and feed rates to remove material at a faster pace. This process allows for faster production and higher precision in the finished product. HSM is used on the UH-60M helicopter to improve manufacturing efficiency by reducing machining time and achieving closer tolerances.
By utilizing high-speed machining, the UH-60M can be produced more quickly, allowing for cost-effective manufacturing. The use of HSM also ensures improved part quality as the high-speed cutting reduces vibration, resulting in smoother surfaces and more accurate dimensions.
