4 Reasons to Choose CNC Machining Over Conventional One

CNC machining is becoming increasingly popular across the manufacturing industry because it can process an extensive range of materials. The manufacturing industry and machining world have seen a huge range of technological advancements over the last couple of centuries.

How CNC Machining can take over the leading position of conventional machining? The following article from TDB Tec will provide the answer.

Principles of CNC and Traditional Machining

CNC Machining, which was known as Computer Numerical Control, is made up of both software and hardware. The operator works with the software to monitor the machine tools, and to create programs. The CNC hardware reads the program including lists of instructions instructing how the machine should work to process parts, and tells the machine tool how to act.

On the other hand, traditional machining is where the operator directly controls all the machine tool’s movements. The operator has a choice of when to move the device without software. The operator also decides which feed, and where and when to stop by using special rulers and gauges, which are embedded in the control levers for better precision.

Here are 5 advantages of CNC machining over conventional:

1. Reduce Labor Costs

Most and foremost, how to maximize profit is always causing major headaches for investors.

In the case of conventional machining, every machine will need a dedicated technician with experience and extensive knowledge over years of practice. 

In contrast, CNC machining is hugely controlled by a software program and requires much less labor to operate systems. 

For CNC machining, one experienced machinist is enough for multiple machines in the factory. Becoming CNC proficient demand less advanced training, which means that CNC machining will reduce labor costs. With the powerful aid of computers, human error was created to nearly zero.

Moreover, the CNC machine operators are safe from any sharp parts behind a protective construction since they can see machine tools via the glass. The operator does not necessarily need to go close to the spindle or mill or come near the cooling fluids. Some fluids that are dangerous to human skin might be produced during processing.

2. Reduce Time-Consuming Tasks 

Traditional machining normally has more than a test part, since prototypes are needed to simulate designs and map their feasibility. Before CNC, the operator must get to know the technology. Every manufacturer has to chalk out actionable prototypes, test-run them, then work on the machining process. This whole routine usually took several days or sometimes even months when done manually.

However, with CNC machining, operators can produce without the prototypes necessary. Using CNC Machining can reduce test run time for producers. 

The advent of CNC machines ushered in software programming wherein you could input your design. There are visualization systems that allow the operator to see what will happen after the tool passes are finished. 

This means the manufacturer can save the extra expenses for prototype development, saving time and labor costs.

If a company is producing parts, then using CNC machining instead of conventional cutting will result in faster production times. The more advanced equipment used in CNC machining allows it to produce parts in less time than conventional cutting due to better accuracy and faster feed rates. Faster production speeds are possible.

3. Large Quantity, Highest Quality in Producing

As TDB Tec mentioned above, because conventional machining requires manual effort, it is mostly set for low-volume, small-quantity projects.

CNC machines, however, are built to provide maximum accuracy whether they are tasked to produce a few dozen metal machined parts or thousands of them. Furthermore, the CNC technique owns the ability to better part replication and to develop extremely complex parts thanks to updated regularly per specifications CNC machining utilizes advanced software. 

In terms of volumes, CNC machines can produce several thousands of 100% identical parts in a record time since they are built to control exact velocity and positioning. That is a feat that is impossible to achieve with handheld or conventional machining. Machines can be programmed to apply the same cut or do the same finishing repeatedly without compromising the quality of the machined part. 

When it comes to quality, CNC machines have high-quality material that gives them resistance to wear and tear, which is common with conventional machining. As a result, they can run 24 hours a day with timely but quick maintenance. CNC machines also come with automated cooling systems, reducing the chances of heat damage. Many advanced machine models come with built-in chip storage and a conveyor belt for chip management. 

Parts can be lighter and stronger, more consistent with the aid of complex geometry. Parts made by CNC machines can much smaller than would be possible for a conventional machine. CNC machines are known for their accuracy and repeatability, which allows for parts to be made quickly and more precisely. 

4. Work Well with Every Material Type in CNC Machining

This is probably the biggest advantage CNC machining has over conventional machining. CNC machines can utilize almost every type of material, including metal, steel, wood, foam, or sensitive plastics. 

The accuracy of CNC systems is dependent on the type of controller used. If a more accurate positioning system is used for the controller, then better accuracy can be achieved. With conventional machining, the degree of accuracy depends on how well an operator can guide the machine.

After machining is complete, the part needs to go through finishing processes such as grinding and polishing to achieve a smooth surface finish. The accuracy of conventional machining is only as good as the operator guiding it through manual movements.

With CNC systems, there is no need for manual inputs from an operator, so the finished product will always be more accurate. One factor that determines the accuracy of CNC machining is a mo
