Computer numerical control CNC is the automation of machine tools by means of computers executing pre programmed sequences of machine control commands. This is in contrast to machines that are manually controlled by hand wheels or levers, or mechanically automated by cams alone. In modern CNC systems, the design of a mechanical part and its manufacturing program is highly automated. The parts mechanical dimensions are defined using computer aided design CAD software, and then translated into manufacturing directives by computer aided manufacturing CAM software. The resulting directives are transformed by post processor software into the specific commands necessary for a particular machine to produce the component, and then loaded into the CNC machine. Since any particular component might require the use of a number of different tools drills, saws, etc. In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine.

HistoryeditThe first NC machines were built in the 1. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern CNC machine tools that have revolutionized machining processes. DescriptioneditMotion is controlled along multiple axes, normally at least two X and Y,1 and a tool spindle that moves in the Z depth. CNC_4_axis_Wood_Foam_Mould_Engraving.jpg' alt='Cnc Foam Cutter Software' title='Cnc Foam Cutter Software' />The position of the tool is driven by direct drive stepper motor or servo motors in order to provide highly accurate movements, or in older designs, motors through a series of step down gears. Open loop control works as long as the forces are kept small enough and speeds are not too great. On commercial metalworking machines, closed loop controls are standard and required in order to provide the accuracy, speed, and repeatability demanded. As the controller hardware evolved, the mills themselves also evolved. One change has been to enclose the entire mechanism in a large box as a safety measure, often with additional safety interlocks to ensure the operator is far enough from the working piece for safe operation. Most new CNC systems built today are 1. CNC like systems are now used for any process that can be described as a series of movements and operations. These include laser cutting, welding, friction stir welding, ultrasonic welding, flame and plasma cutting, bending, spinning, hole punching, pinning, gluing, fabric cutting, sewing, tape and fiber placement, routing, picking and placing, and sawing.

Translate programs consisting of specific numbers and letters to move the spindle or workpiece to various locations and depths. Many use G codes Functions include face milling, shoulder milling, tapping, drilling and some even offer turning. Today, CNC mills can have 3 to 6 axes. Lathes. Cut workpieces while they are rotated. Make fast, precision cuts, generally using indexable tools and drills. Effective for complicated programs designed to make parts that would be infeasible to make on manual lathes. Autocad Lt 2009 Update 2018. Similar control specifications to CNC mills and can often read G code. Generally have two axes X and Z, but newer models have more axes, allowing for more advanced jobs to be machined. Plasma cutters. Involves cutting a material using a plasma torch. Commonly used to cut steel and other metals, but can be used on a variety of materials. In this process, gas such as compressed air is blown at high speed out of a nozzle at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the material being cut and moves sufficiently fast to blow molten metal away from the cut. Electric discharge machiningEDM, also known as spark machining, spark eroding, burning, die sinking, or wire erosion, is a manufacturing process in which a desired shape is obtained using electrical discharges sparks. Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric fluid and subject to an electric voltage. One of the electrodes is called the tool electrode, or simply the tool or electrode, while the other is called the workpiece electrode, or workpiece. Master at top, badge die workpiece at bottom, oil jets at left oil has been drained. Initial flat stamping will be dapped to give a curved surface. Multi Spindle Machines. Type of screw machine used in mass production. Considered to be highly efficient by increasing productivity through automation. Can efficiently cut materials into small pieces while simultaneously utilizing a diversified set of tooling. Multi spindle machines have multiple spindles on a drum that rotates on a horizontal or vertical axis. The drum contains a drill head which consists of a number of spindles that are mounted on ball bearings and driven by gears. There are two types of attachments for these drill heads, fixed or adjustable, depending on whether the center distance of the drilling spindle needs to be varied. CNC Automatic Lathe, multi spindle machine. Wire EDMAlso known as wire cutting EDM, wire burning EDM, or traveling wire EDM, this process uses spark erosion to machine or remove material from any electrically conductive material, using a traveling wire electrode. The wire electrode usually consists of brass or zinc coated brass material. Wire EDM allows for near 9. Since the wire is eroded in this process, a wire EDM machine feeds fresh wire from a spool while chopping up the used wire and leaving it in a bin for recycling. Sinker EDMAlso called, cavity type EDM or volume EDM, consists of an electrode and workpiece submerged in oil or another dielectric fluid. The electrode and workpiece are connected to a suitable power supply, which generates an electrical potential between the two parts. As the electrode approaches the workpiece, dielectric breakdown occurs in the fluid forming a plasma channel and a small spark jumps. Production dies and molds are often made with sinker EDM. Some materials, such as soft ferrite materials and epoxy rich bonded magnetic materials are not compatible with sinker EDM as they are not electrically conductive. Also known as a waterjet, is a tool capable of slicing into metal or other materials such as granite by using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance, such as sand. It is often used during fabrication or manufacture of parts for machinery and other devices. Waterjet is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. It has found applications in a diverse number of industries from mining to aerospace where it is used for operations such as cutting, shaping, carving, and reaming.
