CNC machining is one of the most common and popular manufacturing processes that is widely used in various industries. When the Computer Numerical Control was introduced in the 1960s, the CNC machine is an important part of manufacturing processes, be it industrial or commercial.
The process that uses computers to regulate the tools used in creating different types of products is known as Computer Numerical Control. The most common machine tools that are used in CNC machining are mills, lathes, grinders, and routers. For these machines to function, it needs a specialized console and software, and a customized computer program is required before a machining process can work. The computer program uses a specialized language that helps the user to manipulate the machine tools including other factors like the speed, tool positioning, speed rate, velocity and such.
Advantages of CNC Machining It can run the whole year through.
CNC machine can operate continuously for 24 hours a day and 365 days in a year. The machine can be switched off occasionally for scheduled maintenance.
Lowers the production cost
CNC machine tools allow production of parts faster, which would have taken multiple steps in the conventional manufacturing process. The company can benefit from using CNC with the increase in the rate of production. This, in turn, is helpful in increasing the manufacturer’s profits.
It enhances safety
Since in CNC machines the whole fabrication process is automated, it has kept the operators away from harm, promoting a safer manufacturing environment.
It also enhances surface finish and accuracy
When it comes to accuracy, nothing beats CNC. It is amazing because such attention to details is very difficult and very time consuming if not automated. The precision of the jobs cannot be done by a human being and can only be achieved using CNC machines and tools.
Another advantage that CNC machining can provide is the excellent surface finish necessary in some manufactured goods. Comparing this to a conventional method, the human being’s capability has limitations and can suffer from fatigue and human errors. Since CNC machines are not dependent on the capability of the operators, it can produce a more accurate and smooth surface finished jobs.
It offers superior flexibility
In manufacturing a different set of product in a CNC machine, it only needs a change in the program of the CNC machine of their choice. Since the program is stored in the machine’s memory, this program can repeatedly be used whenever it is required. This also helps in getting the job done faster.
CNC machining is easy to set up whenever it is needed. In a fast-paced environment of manufacturing precision products, this flexibility is very important to cope up with the demands.
A wide range of materials
CNC machining can be used to manufacture products from a variety of materials. These materials may include the usual suspects like steel, aluminum, even gold and silver to polymers like polycarbonate and ABS. All of them create products using the CNC machine.
As a general rule of thumb, CNC machining is good for both low to medium volume productions and one-time jobs. It is highly recommended for prototyping because the price of production is low. You can also use CNC machining for parts that require the higher tolerances.
