Machined

The past tense or past participle of the verb 'machine', meaning to shape or process a material, typically metal, with a machine tool. This involves using tools like lathes, mills, and drills to precisely remove material and achieve a desired form, dimension, or finish. The process often entails automated or semi-automated operations to achieve accuracy, efficiency, and consistency in the manufacturing of parts or components. Machining is vital in various industries, from aerospace to automotive, enabling the creation of complex and intricate parts with strict tolerances. The precision involved is critical for functionality and interchangeability.

Machined meaning with examples

• The engineer carefully checked the dimensions of the engine block to ensure the tolerances of the machined surfaces were within specifications. The intricate design required precise machining to create the complex internal passages for coolant flow, ensuring optimal engine performance. Failure to properly machine these surfaces would result in catastrophic engine failure, underscoring the importance of precision.
• After the initial casting, the raw metal component was taken to the machining center where all the external and internal faces were machined to create the required smooth and functional shapes. The CNC machines skillfully remove excess material, leaving behind the desired shape. This included threading and drilling various holes
• The aircraft components, including the wing spars and engine mounts, are meticulously machined from high-strength aluminum alloys to meet stringent weight and strength requirements. Each step of the machining is carefully monitored and measured to ensure conformity of all tolerances and to reduce chances of failure in flight. The processes are highly refined, minimizing waste and optimizing material utilization.
• The prototype gear was machined to a precise tooth profile using a specialized hobbing machine to ensure smooth and efficient power transfer. During this process, the teeth were precisely cut to interlock and the gear was hardened. The final gear has been machined for extreme stress resistance and the highest tolerance is required to ensure that the gear will be able to handle the constant stresses.
• The skilled technician examined the machined finish on the stainless-steel surgical instruments, ensuring that the surfaces were smooth, burr-free, and suitable for their intended use. High levels of care are needed to maintain sterility and facilitate disinfection after each surgery. The use of machine tools enabled the fabrication of finely crafted instruments with exceptional accuracy, allowing surgeons to perform highly advanced procedures.
