CNC machining involves programming a series of movements through coordinates into a computer program and then allowing the machining tools to cut into a substrate according to the plotted path. It is an efficient system that allows for precise automated machining on large runs. Typical CNC machining originally ran on a 3-axis Cartesian system, with an x-, y-, and z-axis allowing for three-dimensional machining. However, with developments in machining technology and improvements in computing, additional axes were introduced to allow for even tighter machining for more intricate physical geometries.
A typical 3-axis machining plot includes an x-, y- and z-axis, accounting for horizontal, vertical and depth movement. This array allows a CNC machine to be programmed according to three axes that encompass a fully three dimensional space. Programmers realized that additional axes could be created to allow the machine a better command of a given area. The five-axis CNC machine was developed to include rX-, rY- and rZ-axes, each of which represents a rotational plot around and parallel to the actual x-, y- and z-axes. These rotational axes allow the tool to tilt from side to side while moving. With these rotational spaces defined, a programmer can enter a much more intricate pattern for a machining tool to follow. Modern 5-axis machines can cut as close as 3 microns, for an almost perfect cut. Suddenly, applications requiring tighter tolerances were possible to machine with fully-automated equipment, a cut to both cost and labor.
With the advent of 5-axis machining, manufacturers could implement the new method in a variety of ways, leading to a diversity of 5-axis machines. There is typically no “standard” make up of 5-axis machines; in fact, many 5-axis CNC machines are designed with a specific application in mind.
Since the invention of 5-axis machining, developers have introduced additional axes to increase functionality, but for more basic automated needs 5-axis CNC machining remains one of the more common CNC arrays.
With five axes of movement possible, the programming needs can look daunting, but there are many basic CAD/CAM programs that can make the process go smoothly. However, simple programming entries are not exclusive when using a 5-axis machine.
One major concern with 5-axis machining concerns the position of the substrate. Because of the degree of movement available with a 5-axis machine, the substrate should be relatively free in space. Many 5-axis machinists will suspend the substrate in order to achieve this physical freedom. When a substrate is relatively free in this manner, the tool has the freedom to move around and cut it from almost any angle, as designed. However, because a 5-axis CNC can operate with a number of different tools, this is not always necessary.
Even though 5-axis CNC machining can provide a high level of freedom for tooling projects, it is not always the best choice for a job. Some jobs do not require the full level of axis rotation that 5-axis machining provides, while others require more. Simple jobs that can be performed by either a 3- or 5-axis CNC require thorough scrutiny to decide which of the two machines would be more cost effective to use in the process.

A Computer Numerical Controlled (CNC) router is a computer controlled machine for composites, aluminum, steel, plastics, wood and foams.
It is a specific version of a CNCtool that are listed below.
Drills are commonly used in woodworking, metalworking, and construction and most “do it yourself” projects. Specially designed drills are also used in medicine, space missions and other applications.
Electric discharge machining (EDM), sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby 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 liquid 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’.
A milling machine (also see synonyms below) is a machine tool used to machine solid materials. Milling machines are often classed in two basic forms, horizontal and vertical, which refers to the orientation of the main spindle. Both types range in size from small, bench-mounted devices to room-sized machines. Unlike a drill press, which holds the workpiece stationary as the drill moves axially to penetrate the material, milling machines also move the workpiece radially against the rotating milling cutter, which cuts on its sides as well as its tip? Workpiece and cutter movement are precisely controlled to less than 0.001 in (0.025 mm), usually by means of precision ground slides and lead screws or analogous technology. Milling machines may be manually operated, mechanically automated, or digitally automated via computer numerical control (CNC).
Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, 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 metal being cut and moves sufficiently fast to blow molten metal away from the cut.
A CNC router machine gives more flexibility to the manufacturing process. It can be used in the production of many different items, such as: door carvings, interior and exterior decorations, wood panels, sign boards, wooden frames, moldings, musical instruments, furniture manufacturing and so on. In addition, the CNC router makes thermo-forming of plastics easier by automating the trimming process. CNC Routers help ensure part repeatability and helps factory output.
The use of a CNC router machine guarantees savings in time and money. The CNC router machine produces each of its elaborately shaped products in a very small amount of time. In addition, the CNC router machine eliminates the need for an employee to stand at the router. A computer controls the operation of the router. Either the computer linked to the router can stand adjacent to the manufacturing devices, or it can sit at the desktop of the operator.
In other words, the operator of the CNC router machine can sit at his or her desk and direct the movement of the device that holds the router bits. The operator maintains control of this device, a machine part that is called a gantry.

The component manufacturing industries are one of the most important sectors in the country’s economy for the past couple of decades. The multiplier effect of the economic output of these industries acts as a catalyst to the economic stability of the country. Therefore these industries should take all the necessary steps to improve their efficiency by inducting the latest in automation technology in their component manufacturing lines. For instance, the Computer Numerically Controlled or CNC machines as they are popularly known as are widely used in many industries to make components that may be used in the final assembly process.
While evaluating various vendors who offer a whole range of CNC machines including the router CNC, the plasma CNC and the plasma cutter, you would have to make your purchase decision based on certain criteria. What are these criteria and how best can you make your evaluation and the purchase decisions? This is what we would be discussing in greater detail here.
The CNC machine that you are evaluating should follow an open architecture standard in the CNC cam software and the CNC router software that come along with the machines. Now what is the advantage that you can get in your manufacturing facility if the router CNC has an open software platform? Each and every machine in the manufacturing industries these days come with their own software based controls.
An open architecture based CNC router software can help in the integration of the various components in your manufacturing system. This would help you plan your production better and also help in minimizing the waste in your manufacturing plant. This could translate into lower input costs and could save quite a bit of money for your manufacturing operation in the long run.
The other criteria that you could use to evaluate the router CNC manufacturers that you are currently considering are the product range that they have. The manufacturer who has a well defined product range can be the best partner for your organization. The CNC machines that you get from these manufacturers will be ideally suited for the manufacturing operations that they are intended for as they would have a product line for each specialized manufacturing activity. This would help you get the best possible finish on the components that you make using these machines.
The laser CNC machine that you buy would therefore improve your manufacturing capacity and improve the precision with which the various processes in the component manufacturing plant are completed. This will result in better revenues which will eventually translate into higher profits for your company.
Once you install CNC machines in your component manufacturing facility, you would start to find that the overall productivity in your plant has improved. Further improvements in productivity could then be brought about by going in for better manufacturing practices like cell manufacturing etc. This would optimize your production capacities to the maximum and allow you to make the most out of the money that you have invested in your manufacturing facility.
