Computer numerical control (CNC) machining is the manufacturing process of using pre-programmed software to control the movement of factory tools and machinery. In precision machining, the automated tools are programmed to efficiently cut metal components into their desired dimensions.
Advantages of CNC Machining
The use of CNC precision machining, compared to manual machining, offers improved accuracy, productivity, efficiency, and safety, due to reduced human interaction with the machinery.
CNC machines are able to run unmanned for extended periods of time and in the event of an error, the CNC software automatically ceases its operation and calls for a supervisor.
CNC production also allows for greater speed of production as parts that would otherwise require multiple steps to manufacture can be produced quickly by the automated equipment.
Types of CNC Machines
CNC milling is a process that is similar to drilling or cutting. Milling can perform these processes for a variety of production needs and utilizes a cylindrical cutting tool that can rotate in various directions.
Unlike traditional drilling, a milling cutter can move along multiple axes. It also has the capability to create a wide array of shapes, slots, holes, and other necessary impressions.
The lathe is the pioneer for being the machine for metal cutting. Lathe machines shape metal materials by cutting in a circular direction with indexable tools. With CNC technology, the cuts are carried out with precision and high velocity. CNC lathes are used to produce complex designs that wouldn’t be possible on manually run versions of the machine.
In a plasma cutter, the material is cut with a plasma torch. The process is foremost applied to metal materials but can also be employed on other surfaces. In order to produce the speed and heat necessary to cut metal, plasma is generated through a combination of compressed-air gas and electrical arcs.
Electric Discharge Machines
Electric-discharge machining (EDM) is a process that molds pieces into particular shapes with electrical sparks. With EDM, current discharges occur between two electrodes, and this removes sections of a given workpiece.
Water Jet Cutters
Water jets are used in CNC machining to cut hard materials, such as granite and metal, with high-pressure applications of water. In some cases, the water is mixed with sand or some other strong substance. Factory machine parts are often shaped through this process.
Water jets are a good alternative to cutting materials that are unable to bear the heat-intensive processes of other CNC machines. Water jets are often used in the aerospace and mining industries.
