CNC Milling Machines and Their Basics

CNC milling machines are nothing but cutting tools. These are programmed and managed by Computer Numerical Control (CNC) systems. They accurately remove materials from a workpiece. Using a Computer-Aided Design (CAD) software, the end result which is a specific part or product is achieved.

Design of CNC Milling Machines

A main spindle and three-linear –axes are the components of CNC milling machines. The three-linear-axes are required to position or move the part to be machined. More precise shapes are formed with the help of 4th or 5th rotational axis which is part of advanced forms of milling machines. Also, when varying dimensions and sizes are to be machined these advanced versions are used.

Working principle of CNC machines

Its working principle is very simple and easy to understand. The milling process involves securing a piece of pre-shaped material (also known as the workpiece) to a fixture attached to a platform in the milling machine. A rapidly rotating tool remove small chips of the material until the desired shape for the part is achieved. For machine parts that are not symmetrical from an axial perspective, milling is generally used.

Earlier, milling machines in CNC machining workshops used to be manually operated. Highly skilled operators had to use several machines together to machine a more complex part or product. Even if one machine was used several settings were put to work in order to get the task done. The kind of skills required was complex and only experienced operators were put to work. There were more chances of error always associated even with high precision involved. But thanks to the technology, today with the advancement of technology such a CNC controls and Automatic Tool Changers (ATCs), greater efficiency, flexibility, and speed can be achieved.
