CNC Machine Types Advantages & Disadvantages
Computer Numerical Control (CNC) machines are automated milling devices that can manufacture industrial components without direct human assistance. They use coded instructions that are sent to an internal computer, which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines, ranging from drills to plasma cutters, so they can be used to make a wide variety of parts. The most common CNC machines are milling machines, lathes, and grinders. Milling machines automatically cut materials, including metal, using a cutting spindle, which can move to different positions and depths as directed by the computer instructions.
As the world becomes increasingly automated, there is a growing demand for machines that can produce intricate and precision objects. This demand has led to the development of computer numerical control (CNC) machines, which are highly specialized machines that can create products using a variety of cutting and grinding techniques. CNC machines have many industrial applications, including the production of parts for automobiles, aircraft and medical devices.
The advantages of using CNC machines over traditional hand tools are too many to count. From increased accuracy and speed, to reduced scrap and manufacturing costs, there is a reason why so many manufacturers are switching to CNC technology. In this article, we will explore some of the benefits of CNC technology.
Advantages of CNC Machine
CNC Machines have following advantages –
CNC machines can be used continuously 24×7 throughout the year and only need to be switched off for occasional maintenance.
CNC machines are programmed with a design which can then be manufactured hundreds or even thousands of times. Each manufactured product will be exactly the same.
Less skilled/trained people can operate CNC machines unlike manual lathes / milling machines etc. which need skilled engineers.
CNC machines can be updated by improving the software used to drive the machines
Training for correct use of CNC machines is available through the use of ‘virtual software’. This software is like a computer game that allows the operator to practice using the CNC machine on the screen of a computer.
Modern design software allows the designer to simulate the manufacture of his/her idea. There is no need to make a prototype or a model. This saves time and money.
One person can supervise many CNC machines as once they are programmed they can usually be left to work by themselves. Only the cutting tools need replacement occasionally.
Disadvantages of CNC Machine
The use of CNC machines has many advantages, but it also has some disadvantages. For one, the machines can be very expensive to purchase and operate. They also require a lot of training to use properly. Additionally, CNC machines can be dangerous if not used correctly.
CNC machines are more expensive than manually operated machines, although costs are slowly coming down.
The CNC machine operator only needs basic training and skills, enough to supervise several machines. In years gone by, engineers needed years of training to operate centre lathes, milling machines and other manually operated machines. This means many of the old skills are being lost.
Fewer workers are required to operate CNC machines compared to manually operated machines. Investment in CNC machines can lead to unemployment.
Many countries no longer teach pupils / students how to use manually operated lathes / milling machines etc… Pupils / students no longer develop the detailed skills required by engineers of the past. These include mathematical and engineering skills
