Numerical control Wikipedia. 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. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD. 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,2 and a tool spindle that moves in the Z depth. 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. DeskProto 3D CAM software offers 3D CNC machining for nonmachinists. Import STL files, create toolpaths, use your 3 4 or 5axis CNC milling machine. 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. Examples of CNC machineseditCNC mills use computer controls to cut different materials. They are able to translate programs consisting of specific numbers and letters to move the spindle or workpiece to various locations and depths. Many use G code, which is a standardized programming language that many CNC machines understand, while others use proprietary languages created by their manufacturers. These proprietary languages, while often simpler than G code, are not transferable to other machines. CNC mills have many functions including face milling, shoulder milling, tapping, drilling and some even offer turning. Standard linear CNC mills are limited to 3 axis X, Y, and Z which allows for 2. D machining, but others may also have one or more rotational axes which allow for advanced 3. D machining3. Today, CNC mills can have 3 to 6 axes.

CNC lathes are able to make fast, precision cuts, generally using indexable tools and drills. They are particularly effective for complicated programs designed to make parts that would be infeasible to make on manual lathes. CNC lathes have similar control specifications to CNC mills and can often read G code as well as the manufacturers proprietary programming language. CNC lathes generally have two axes X and Z, but newer models have more axes, allowing for more advanced jobs to be machined. Plasma cutterseditPlasma cutting involves cutting a material using a plasma torch. It is 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 machiningeditElectric discharge machining EDM, sometimes colloquially also referred to 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. When the distance between the two electrodes is reduced, the intensity of the electric field in the space between the electrodes becomes greater than the strength of the dielectric at the nearest points, which electrically break down, allowing current to flow between the two electrodes. This phenomenon is the same as the breakdown of a capacitor. Chess 7 Serial Key. As a result, material is removed from both the electrodes. Once the current flow stops or it is stopped depending on the type of generator, new liquid dielectric is usually conveyed into the inter electrode volume, enabling the solid particles debris to be carried away and the insulating properties of the dielectric to be restored. Adding new liquid dielectric in the inter electrode volume is commonly referred to as flushing. Also, after a current flow, a difference of potential between the two electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur. Multi Spindle MachineseditA multi spindle machine is a type of screw machine used in mass production. This automated variety of CNC machine is considered to be highly efficient by increasing productivity through automation. This machine is constructed in such a manner that it 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. Wire EDMeditWire EDM came into commercial use in the 1. Also 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.
