What Is CNC Machining And How Does It Work?
Sep 01, 2021
CNC machining is just one method of a computer-controlled solution that allows engineers, machinists and makers to create a prototype or part from a computer design file.
Another prototyping process is 3D printing, which is also known as additive manufacturing. The key difference between these two processes is that whilst CNC machining is a subtractive process, 3D printing is an additive process.
Since the invention of CNC machines, the manufacturing sector has been drastically altered and the number of machining steps requiring human intervention has been significantly reduced. CNC automation minimised the number of errors and gave CNC operators more time to do other things, increasing overall productivity.
How does it work?
CNC machines are electro-mechanical devices that can manipulate tools around a varying number of axes with high precision, whilst following instructions from a computer programme.
Machining is a way to transform a stock piece of material such as aluminium, steel or titanium into a finished product, prototype or part.
