What is CNC machining?
Machining is a method of removing excess material from a workpiece to give it a specific shape, dimensions and surface properties. It is one of the fundamental manufacturing methods in the mechanical engineering industry, used for metals, wood, plastics and composites alike.
CNC (Computer Numerical Control) machining is an advanced industrial process in which cutting tools are controlled by computers. In this process, a computer program precisely controls the movements of the machines, enabling the creation of complex cuts and shapes. This process is carried out using various machines and cutting tools. There are several basic types of machining:
- milling – a process involving the removal of material using a rotating tool – a milling cutter. It is a versatile method allowing for the creation of complex shapes and high precision,
- cutting – involving the separation of a part of the material from the whole, usually using saws or other cutting tools,
- turning – a machining method in which the material is rotated around its own axis, and the cutting tool removes excess material, giving the workpiece the desired shape,
- grinding – a machining process used to achieve very smooth and precise surfaces by abrading the material with a grinding tool,
- drilling – i.e. creating holes in the material using a special drill bit.
CNC machining – what does it offer?
An innovative technology in the manufacturing industry, significantly increasing production capabilities thanks to its precision, efficiency and adaptability – this is what characterises CNC machining. What is the secret behind its success and why has it revolutionised the manufacturing industry?
- Precision and repeatability. The CNC method allows for highly precise machining of materials whilst maintaining high repeatability. CNC programmes can be used repeatedly, ensuring that the parts produced are identical.
- Complex shapes and designs. Thanks to computer control, CNC machining enables the creation of even highly complex and detailed shapes that would be difficult or impossible to produce by hand.
- Automation. CNC processes are largely automated, which reduces the need for constant human supervision, increasing production efficiency and reducing the risk of errors.
- CAD/CAM software. CAD (computer-aided design) and CAM (computer-aided manufacturing) software are frequently used for the design and programming of CNC machine tools, facilitating the creation of complex designs and their implementation.
- Versatility. CNC machines are versatile and can be used for various types of machining, including milling, turning, drilling, threading and grinding.
The use of CNC machining in mass production
CNC machining plays a vital role in mass production, offering numerous benefits and increased efficiency compared to traditional manufacturing methods. The use of CNC machines primarily ensures the aforementioned precision and repeatability, which is crucial in mass production. Thanks to computer programming, every part is identical, which is unachievable with manual machining.
Such machines can also operate quickly and continuously, which significantly speeds up production processes. Automation allows machines to run continuously, even outside operators’ working hours. Furthermore, CNC machine tools can be quickly and easily reprogrammed to produce different parts, enabling flexible adaptation to changing production requirements without the need to invest in new equipment.
Precise cutting and the minimisation of errors in CNC machining also help to reduce material waste, which is beneficial from both an economic and environmental perspective.
Where is machining used?
CNC machining is used in many sectors and fields of industry. Here are some of the sectors where this technology is widely used:
- the automotive industry – e.g. in the production of car parts: from engines to gearboxes, i.e. where high precision and repeatability are required,
- the aerospace industry – for the production of complex aerospace components that must meet stringent safety and precision standards,
- machine and equipment manufacturing – for the production of advanced machine and equipment components for various industrial sectors,
- the medical sector – including the production of precision medical instruments, implants and diagnostic devices,
- electronics – in the production of electronic components and housings, where micro-scale precision is required,
- energy sector – in the production of turbine parts, generators and other key energy components,
- carpentry and woodworking – for the precise cutting and shaping of wood in the production of furniture, decorative items and structural elements,
- construction industry – in the production of precision structural elements, moulds and tools,
- the education and research sector – e.g. at universities and research centres for teaching and developing new production techniques (including prototyping).
