Computer Numerical Control (CNC) of manufacturing machines such as lathes and mills was the next stage of development from Numerical Control (NC). NC control had allowed the machines to be run automatically using a fixed program for the first time. This increased automation of the manufacturing processes led to considerable improvements in the consistency and quality of components. The program was, however, long winded to create and difficult to alter.

The addition of a computer within the machine allowed the program to be viewed and edited making it easy for alterations to be made to what had previously been a fixed program. This allowed operators to write programs directly into the machine and update and optimise them as they went. This required a new breed of machine operators who had the skill and training required to program the machine from engineering drawings in addition to their traditional skills.

The next stage of development was Computer Aided Manufacture (CAM), this allowed the program to be created offline from the machine, not by typing in dimensions from a paper drawing, but by taking the geometry directly from Computer Aid Design (CAD) files. A software package would be used to create the program from 2 Dimensional CAD data of the geometry and then add tool and speed/feed information. This program could then be post processed into a language appropriate to the machine being used. This development further increased the required computer skills of the machinists but made programming of complex shapes just as simple as creating simple shapes. It also reduced the chances of errors within the program as more of the programming was automated.

The current state of the art is 3D CAD/CAM, which allows programs to be created directly from the 3D solid models created by the design engineers. This technology allows parts to be machined without any from of paper drawing, as all the tool paths are derived from the 3D model. The advantages of this process are most obvious when creating development or prototype parts as not only is the programming time considerably reduced but also programs can be simulated and verified offline. Therefore no time consuming line-by-line proving of the program is necessary at the machine. A further advantage to this system is that more complex three-dimensional forms can be easily programed allowing more flexibility to the designers, and where necessary making the creation of more stylish shapes, cost effective even for very low production.

All these developments have completely revolutionised workshop practices within a generation, as machinists have evolved from skilled operators running manual machines, to computer literate programers able to drive complex 3D CAD packages that had previously been the domain of the designers.

Do you know about CNC tube bending machines? These are designed in a fashion to minimize the time of set up and to maximize production. The CNC tube bending machines are available with many companies. Some of the companies have also launched CNC tube bending machines that feature electrical servo-drives on all axes and these are available in single as well as multi stack versions.

CNC tube bending machines with multistack benders facilitate complicated bending without the requirement of tool change. In case, you cannot apply a multistack tool for stability reasons, try to switch over to an automatic clamp die changing system that will easily accommodate up to eight clamp dies.

The CNC tube bending machines feature excellent bending procedures that are programmable and boosting via the transport carriage in conjunction with the boosting in the area of pressure die. The boosting tends to minimize wall thinning towards the outer bend that further facilitates narrow bending. You can easily achieve a radius of less than 1 x OD. Other important features of CNC tube bending machines include the following:

An MMI multicontrol 2020 system
TFT monitor
Touchscreen
Plausibility verification
XYZ coordinate recalculation into bending parameters
Flexible programming
Multitasking
3-D displays
Integrated modem
Access to the world wide web

The integrated modem and access to the internet works towards providing the best of remote maintenance and technology support.

The CNC tube bending machines has a bending template. This helps in bending the pipe as desired. The unbent portion of the pipe is supported on a pipe that supports rail carries. It is also adjustable in height. The adjustment of height can be easily done by a drive and it is best suited for step-less positioning. This easily sets the pipe-supporting rail to a height that is already specified by the CNC control unit. Before bending the pipe, the height to which the pipe has been moved, is determines via a functioning program that is dependent on a full set comprising of tool data that has been input into the control unit.

Here are the features specifications of a CNC tube bending machines:

Industrial PC control
I/O card machine control
Input of all program to industrial PC via touch screen
Input data of Y.B.C.
Input data according to Descartes X.Y.Z coordination to build bending parameter.
The profile of tube will display on the PC as per the built parameter or input data.
Servo-motor control that feeds axis-X as well as rotates Axis-B, and then bends Axis-C that’s derived via hydraulic pressure
Program transmits via flash disc, floppy disc or the World Wide Web.
Adopt windows XP Embed operation system.
Process of the function auto and manually
Operation via Pedal
Single step change via the operator

Automatic bending rebound numerical compensation data s per accurate measured data.

There are many factors to consider when choosing a CNC plasma cutter. Let’s look at some questions you will need to ask and be able to answer.

What is the thickness of the material you will be cutting? Start with the thickness of the materials that you will be cutting most often. A good general rule is to choose a plasma cutter capable of cutting twice your normal cutting thickness. It may seem like you are buying more than you need, but it will provide you with the capability to cut thicker material when needed, and provide you with high quality, high precision cuts.

Does the cut quality meet or exceed your application? The quality of the cut on the finished piece ultimately effects the quality of the part as well as the time spent in secondary operations on clean-up. Modern precision plasma systems provide tight focused arc providing a clean, smooth and straight cut with a narrow kerf, as close to laser quality cut metals as possible.

What are the consumable costs? The manufacturer should readily provide you with details for consumable life. It is important to find a plasma cutter that makes consumables last as long as possible. Always purchase the recommended consumables for your machine. Cheaper brands will not last as long nor will they provide high quality cuts.

What is the reliability of the machine? The best plasma cutters are designed and built to exacting machine tool quality standards. They are built to be strong, heavy duty and durable. A plasma cutter with a fully welded cutting table is capable of handling heavy plate loads (2″ and more) and will withstand rigorous daily usage without any loss of accuracy or quality.

Is it easy to use? For a plasma cutter to provide long-term value, it must be easy to set up and use. Look for one that is simple to learn and operate and which comes loaded with time-saving features such as a large shapes library, import of AutoCad files with nesting possibilities, kerf-on-the-fly adjustment, and auto-gas console integration. A machine that is easy to use and which incorporates cost-saving features will increase your productivity and your bottom line.

How much should you expect to spend? An investment in a CNC plasma cutter must be one that makes sense today and for years to come. A machine that cuts your parts right the first time and without the need for multiple secondary operations will provide a faster return on investment as well as improve productivity. By choosing a high quality plasma system based on it’s intended use, features and capabilities, you will buy a machine that may not be the cheapest or least expensive. If you buy cheap, you will buy your plasma cutter more than once.

You get what you pay for. Be willing to pay for a quality CNC plasma cutter that will make, not cost, you money. Buying quality is never a mistake.
