Rapid Machining: Importance, Advantages, Disadvantages, and Applications
Rapid machining is the machining of parts and prototypes with an explicit focus on reducing the time taken to make the parts. It usually involves CNC machining (including milling, turning, etc.) but may also include manual machining for simple parts. Machining can be expedited in various ways. Depending on the customer’s requirements, rapid machining may involve increased use of high-torque machines and roughing techniques to speed up material removal. It may also involve easy-to-machine materials like aluminum alloys over materials that require more time to machine. Although not mutually exclusive, rapid machining can be seen as a counterpoint to precision machining, which prioritizes accuracy and detail over speed.
