Usage of CNC Software for Faster Manufacturing Process

CNC stands for Computer Numerical Control. The CNC software helps in performing all the manufacturing works automatically. One can say that CNC software is a computer controlled manufacturing. While many people are unaware of the term CNC, it has actually been helping the manufacturing processes since 1970s. If you have a manufacturing company then you will be dealing with the CNC software every day.

Use of CAM and CAD
CNC program can be developed manually for simple applications. But for more complicated and complex process program writing is difficult. Hence a Computer Aided Manufacturing or CAM system is used. It is a software program that runs on a computer and helps in writing the CNC program. Many companies also use Computer Aided Design or CAD along with CAM system. The CAD drawings are developed by design engineering department of the company which reduces the requirement for redefining the configuration to CAM system.

Advantages of CNC

Faster process: Using CNC along with CAD-CAM programs makes the overall process of receiving models from clients, designing the product, managing the projects and machining it faster. The delivery of products to the clients and market is much faster with the use of this software.
Handling complex process: Managing many complex machines has become easier with the CNC. With CAD-CAM software it has become easier to calculate the machine cycles. Now it is easier to perform any task by setting the tool path.
More control over the process: The CAD-CAM has now made the CNC functionality much better. The control over the whole process is much better with the CAM Tree Manager that tracks the task from beginning to end.
Better benefits: High speed machining enhances the productivity and CNC works towards that. With the new CAD-CAM software, the cycle time is reduced as well as the wear and tear of machines.

Types of Industries which uses CNC
CNC has now become an essential part of almost every manufacturing company. Overall the manufacturing processes have not only become easier but also have improved due to the use of CNC software. There are some fields where the use can be vividly seen. These are:

Electrical Discharge Machining Industry: The process of removal of metal using electrical sparks by burning away the metal is called the Electrical Discharge Machining (EDM). CNC is used in this process in two kinds: vertical EDM and wire EDM. In the vertical EDM an electrode in the shape of the cavity is machined into a mold. The wire EDM is used in fabrication industry to punch and die for die sets.
Metal Removal Industry: Earlier conventional machine tools were used in this industry like milling, tapping, boring, drilling, reaming etc. But now all these processes are controlled by CNC software. All kinds of operations in turning like boring, turning, grooving, knurling, facing, and threading are done on CNC. Grinding operations are also now controlled by CNC grinders.
Woodwork Industry: CNC is also used in woodwork industry just like any metal removal industry. A number of tools and many operations to be performed on wood are done automatically using CNC. Routing and drilling are some common operations in this field that can be automated.
Metal Fabrication Industry: Fabrication of metal refers to the work done on thin plates of metal. All this activity of sheets being reared to size, punched with holes and bend requires a lot of effort. CNC is heavily involved in the overall process of shearing, punching, laser cutting, flame or plasma cutting, forming, and welding.
Other applications: Electrical component manufacturing industry use CNC software heavily for their operations. Many lettering and engraving systems also use CNC in their overall process.

Reasons For The Popularity Of CNC Turning

By Mike On 20:06 In cnc turning

People use lots of products in their day to day lives without even thinking about them. Many of them are unaware of the facts regarding very common things; facts like the material they are made with, how they are produced, what technology has been in use in their production.

Many a times, it is a real wonder that for producing a tiny product, there have been a lot of technology involved and large machineries were utilized in their manufacturing process. Industries and Workshops are places where products are being produced in large scale.

Take the piece of little pawn people play in chess. Making in its entirety can be viewed in YouTube videos. A little piece of machinery is used in producing that chess piece; the basic works done by the machine is cutting and turning. The Long Cylindrical steel piece is being turned continuously and a sharp pointed tool is made to travel on that steel cutting through it repeatedly; this acted like etching out the unwanted portions of steel and slowly the majestic form of a chess piece emerged.

People have to wonder about uniformity of action that took place, limited number of occurrences and already calculated measurements carried out accurately in its minutest detail precisely as planned and programmed. Credit goes to computer numerical control or CNC Turning. This refers the method in which main material is being rotated or turned and a sharp pointed cutting tool is sent parallel on its surface. The machine that does the turning part is known as lathe. This is being used from ancient days onwards. Lathe keeps material intact and spins it and allowing the cutting tool with single point, removes the unwanted portion and shapes the material in desired part. This turning action influences complex shapes including plain, filleted, contoured, tapered, threaded and radius profiles. An operator will be applied and directing cutting tool on that material in olden days.

Nowadays, Computer Numerical Control with its program control operation of cutting tool and lathe part. There is no need for human operators. With this pre-programmed design, exact tolerance, precise turn and any type of shape like curved, straight, conical and grooved is possible.

Advantages of CNC Machining:

Mass production: It is ideal for mass production. Once sample is all right, then producing large quantities of similar parts is easy.
Efficiency: CNC lathe enables simultaneous motion of X and Z axis; making cutting tool move around the very corner of the part so that a fillet can be produced.
Accuracy: Unimaginable accuracy can be obtained through computer programs. Tools can be controlled as accurately as 0.0001 inches. Without changing this tool, cutting at many places can be done.
Speed: No need to elaborate on the speed of computer controlled parts. This tremendous speed has resulted in increased efficiency in overall production.
Cost Effectiveness: Cost of CNC machines is very expensive. However, once it is procured as investment part, then the cost of production will be very less due to its speed and large quantity of production.

Understanding CNC Programming And How It Will Help Your Career

By Mike On 16:59 In CNC Programming

Have you heard of CNC programming, training and how it can change your career and want to know more, then, this article is for you! CNC stands for computer numeric control which involves feeding data into a machine and then operating it. Needless to say that this will require some amount of knowledge and skills for which you must undertake a CNC programming training.

Who can take this training?

This training is for those who wish to become CNC machine operators and also programmers. CNC machines help to produce different components for various manufacturing industries such as aerospace and automobiles. These are operated by computer programs and thus it is obvious that the skill sets required for this job is entirely different from those who work with the manually operated machines.

As with any other job; you have to start in this position also at entry level and then work your way up as you gain experience.

What Does the CNC programming training teach?

These programs focus on training candidates on the basic of:

Manual operations
Milling and lathe operations
Machining center basics
Turning centre basics
Mechanics
Parts and codes
Co-ordinates

All good training programs will include content and information on CNC milling machines as well as several other tools that are often used in industry.

Why Should You Take this Training?

It is quite obvious that you will have an edge over other candidates in the job market. There are plenty of job opportunities for people with such skilled training. Since this is a computer operated machine; you will need to understand to build certain codes too which are quite simple, of course and you do not need an advanced computer science degree for it. Nevertheless, it is not possible for anyone to operate a CNC turning machine without proper training.

Benefits of CNC Programming

Some of the benefits are actually the same that you would get from any kind of machine operations such as less fatigue on the part of the operator, lessor or no mistakes that are often caused due to human errors.
CNC machines are part of precision engineering and hence you can expect the same accurate and precise output after every run. Once the right CNC programming has been put in place; the machine will give consistently give the same accurate output.
A simple change in CNC programming will give you an entirely different product on the same machine and hence you need not spend money on buying a different machine for different parts. This is perhaps the greatest advantage of such machines as they reduce investment cost significantly. To make different pieces; all that one needs to do is change the program.
Automatic control, precision and predictability are some of the features for machines run by CNC programs.

You will be surprised to know that there are quite a few CNC programs that don’t require any kind of human intervention to run a machine. This means greater automation and thus lesser labor cost. Moreover, the risks associated with manually operated machines are almost eliminated too.
