Utilizing spinning, computer-controlled cutting tools like drills, end mills, and turning tools to remove material from solid blocks of material and shape items, CNC machining is a subtractive manufacturing method. Manufacturing companies may begin production considerably faster with CNC machining than with other methods since it eliminates the need to produce expensive molds. CNC machining may be produced during and after business hours with little to no human involvement because it is highly automated. Additionally, many CNC machines can work simultaneously on the same design to make the same part, which reduces production lead times and costs.
