CNC stands for computer numerical control. It is a type of manufacturing machine that automates the entire manufacturing process from start to finish. The operator program the machine to perform a specific task. The CNC program directs the machine to cut, drill, or form a certain work piece. After all of the preparation and set-up are complete, the CNC program runs. The result is a customized part. Here are a few ways a CNC machine can benefit your business.

Programming a CNC Machine

Programming a CNC Machine

Programming a CNC machine is easy, but the most challenging part is learning the code. Here’s a brief description of the process: After the setup operator has loaded the raw material into the CNC machine, the machine operator stands by and checks the machine’s progress. The machine will then run and produce the finished parts without requiring a human operator. Some CNC machines can even operate lights-out. When the job is done, the machine will automatically move the finished pieces to their designated area.

Operators Monitor Quality

When the setup operator completes the setup, they hand over the first article piece for quality assurance. Once the setup is complete, the CNC machine is loaded with raw material and the operator stands by to ensure the machine is running. Many machines can run lights-out, but others require a human operator to keep a close watch on it. After the process is complete, the finished parts will be moved to their designated areas.

 Need a Professional to Operate the Machine

Need a Professional to Operate the Machine

The CNC machine needs to be operated by a trained professional. The CNC software communicates with the CNC machine through the G-code language. It is important to understand that CNC machines are not perfect, but that the machine is able to read and interpret the G-code instructions. One of the biggest problems of CNC is the assumption that the computer is perfect. Ultimately, no computer can produce the exact shape that the human eye perceives.

CNC Operator Teamwork

When the CNC operator finishes the shift, he reports to the work center. He gathers supplies for the day. He also talks to the previous shift operator to discuss any problems with the machine or with the part quality. This teamwork allows the CNC operator to plan tool changes and audits. The CNC controller is programmed differently to control the machine’s different behaviors. It uses a CAM or CAD file to perform the desired operation.

Cutting Tools Used in CNC Milling Machines

A CNC machine works by using cutting tools that use various cutting mediums. In most cases, it is the CNC programmer who creates the NC program for the CNC machine. Once the NC program is ready, the operator loads the raw material and tools. Then, he runs a sample piece and measures it with quality assurance tools. This step is necessary to ensure the quality of the finished product. A CNC programmer will send the proper tools and material to the CNC.


A CNC machine can be operated by one operator. The operator will enter a CNC program that tells the machine what to do. The operator will record the results and report back to the quality department. Once the process is complete, the CNC will automatically move the finished part into the designated area. These workers will overlap each other for about 15 minutes. A CNC can be set up for any number of different functions. There are CNC machines with all kinds of functions.
