CNC stands for Computerized Numerical Control. CNC Machining Method is used in manufacturing tasks that involve the use of a computer to control machine tools. The tools that are controlled in this manner are lathes, mills, routers, and grinders. With the use of Computer Aided Design (CAD) and Computer Aided Machining (CAM), CNC replaced many manual machines.
To the observer, it may look like a normal PC controls the machine, but in actual, computer software and control console sets the system apart from CNC machining.
In CNC Machining, machine tool functions with the help of numeric control. In the CNC machine are programmed with CNC machining language which is also known as G-code. This code controls various feature like feed rate, coordination, location, and speed.
CNC also controls exact position and velocity of the machine. With help of CNC, you can manufacture both metal and plastic parts.
CNC Machining Sydney also uses a computer in which the program is fed for cutting of metal as per the requirement of the job. CNC work like a robot; it exactly knows what to do and carry out all cutting processes efficiently. The main purpose of machines is to remove extra metal to give proper shape to metal.
Basically, these machines are handled by an operator who is an expert in the operating these machines. The operator should be expert enough to make precision jobs. Here the role of the operator is minimized as he just has to fill prom of instructions in the computer.
Here precision engineering plays an important role. This kind of engineering is related to electrical engineering, software engineering, electronics engineering, mechanical engineering and at last, optical engineering. It is concerned with designing machine fixture, and other structures which have a high tolerance, are repeatable and highly stable over time.
The fundamental principle of precision engineering is determinism.
Here system behavior is predictable even to the nanometer-scale motion. Work is done more efficiently and correctly. The machine parts that are made here are highly precise.
