A Look Into The Process Of CNC Machining

July 26, 2018

When it comes to CNC machining, tools operate through computer numerical control. A software program is specifically designed and the machines are pre-programmed with G-code that controls everything, including speeds, feed rate, coordination and location.


CNC machining is a highly complex process, which involves four vital stages!



In this first phase, a Computer Aided Design (CAD) software is used to create the models for the parts to be machined. This can either be a 2D or 3D model, depending on what you need. This design allows for a digital conceptualization that can be read by a computer which can be translated to a machine to physically create it.



It is at this stage where a Computer Aided Manufacturing (CAM) software is used in order to convert the CAD into the language readable to program the machines. This language is also known as G-Code.



At this stage, the machine to be used is set up using the correct tools and materials to create the final parts. This machine varies from project to project, as each project requires a combination of different types of machining processes.



This is the stage where the product is finally created. The machines use the CAD design and the G-Code to machine the components specified. With the process being carried out by a computer program and a machine allows for precise and calculated actions, this results in a high quality product that can be duplicated any number of times.


CNC machining, while complex, has proved to be an immensely powerful and influential tool in the machining industry. With the calculated accuracy that the computer-controlled machines provide, machining shops are capable of producing products at a consistent quality.

When you require CNC machining, we at True Gear & Spline have the CNC expertise and equipment to tackle any gear-related job you may have for us. Whatever gear you need – be it spur, helical, or bevel – we have you covered!
