CNC machines have come a long way since it’s first introduction back in the 1940’s. Having evolved from its humble beginnings using ‘punched tape’ technology, engineering advancements has seen this ‘electro mechanical device’ become a valuable tool for many manufacturing facilities worldwide.
Basic Overview
CNC stands for Computer Numerical Control and is a highly advanced machining and printing device. The milling machine is operated using a numerical computer (not by hand) – eliminating the need for labour intensive output.
How does it work?
It basically generates prototypes from a digital software file from which it can process, mill and grind raw materials such as plastics, metals and timber. Its ultimate function is to cut these pieces into a desired shape that can be used for individual machinery parts.
The CNC machine receives digital instructions from two main files including Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) to assist in the fabrication process. However, it does not run the machine itself – it simply acts as a gateway for the CNC machine to interpret the design and therefore helps in initiating the automation process.
Unlike other pieces of machinery, CNC machining delivers incredible precision and drastically minimises the risk of human error during operation. Some of the most common industries that implement CNC equipment include the medical sector, aerospace industry, transportation, marine, oil and gas and the military fields.
What is CNC Machining Used For?
Drilling
The CNC machine can drill holes into materials through the action of spinning a drill bit and moving into its desired position. Whatever solid block of material you may be using, CNC drills are ideal for making precision holes with minimal errors.
Lathes
Also known as inverse drilling, lathes primarily make contact with the material through laterally moving the cutting equipment until it slowly touches the spinning function. With timber and metals being the most common materials used, lathes discard all the unwanted bits and pieces, ultimately creating a valuable component that can be used as the finished product for all types of equipment.
Milling
This is the most common CNC machine used in manufacturing today. It delivers a host of different functions such as boring, drilling and cutting. Using rotary cutting tools to remove materials from the unit, milling has the capacity to produce slots for use in a variety of different applications.
What type of materials can be used in a CNC Machine?
CNC Machines are one of the most versatile manufacturing machines on the market today. Depending on the application, almost any kind of material can be safely used in a CNC machine to suit a range of different projects. This includes fibreglass, wood, brass, copper, aluminium and polypropylene plastics.
