A Brief Introduction to CNC Machining
A Brief Introduction to CNC Machining
August 17, 2021

With the advent of advanced computer programming, automation is the name of the game in almost all industries, and manufacturing is no exception. In the world of manufacturing gears and other highly specialized mechanical parts, automation has given rise to the increasing use of CNC machining

 

From its meaning to how it actually works on the shop floor, learn all about the basics of CNC machining here. 

 

An Overview of CNC Machining

 

CNC stands for computer numerical control, meaning a machine is controlled by a processor to do tasks that require extreme precision such as drilling, cutting, milling, lathing, and a lot more. The accuracy is achieved by feeding exact instructions to the computer, so that the machine may operate with little to no manual intervention. Now, how instructions are fed to the processor will be discussed in the next section. 

 

Basic Operational Procedure

 

First, the exact dimensions of the object to be manufactured must be determined. To perfect this process, computer-aided design or CAD software and computer-aided manufacturing or CAM software are used. Once the specifications are set, the machine must be fed programming commands which will help it perform its desired action. For movements along the well-defined axes of the machine, such as the X and Y axis, a language called G Code is used. Essentially G Code takes care of most of the machine functions on a linear scale. But for random movements which don't fall under the machine's conventional line of motion, a language called M Code is used. Both programming languages are generally used in tandem for most CNC machining processes. 

 

Advantages

 

Since the machines are operated by a computer, the accuracy and speed of the process are unmatched. The cumbersome labour and significant errors of manual manufacturing are easily eradicated by CNC machining. A complicated, bulky machine that might require multiple hands at work can now be monitored by just one operator. 

 

Moreover, it can also significantly lower the cost of machinery on the floor. Most CNC-operated devices have multiple functionalities such as drilling and sawing, built into a single, seamless unit, eradicating the need for different, specialized machines. And although no machine is infallible, CNC machining is one of the best, commercially viable manufacturing processes in the market today.
