CNC Up Close

What exactly does the acronym CNC stand for and what is the function of a CNC machine? CNC machining is a term widely used in manufacturing and industrial applications. The term CNC means “computer numerical control.” The definition of CNC machining is that it is an extractive manufacturing process that typically uses computerized controls and machine tools to remove layers of material from a stock piece, known as a blank or workpiece. The result is the production of a specially designed part. This process is suitable for a wide variety of materials, including metals, plastics, wood, glass, foam, and composites. When talking about the machine itself, the definition of a CNC machine represents the actual programmable machine that is capable of performing the operations of CNC machining independently. 

Overview of the CNC Machine Process

CNC machining, which evolved from the numerical control (NC) machining process that used punched tape cards, is a manufacturing process that uses computerized controls to operate and manipulate machine and cutting tools to shape stock material (e.g. metal, plastic, wood, foam, composite). 

Basic CNC Stages

While the CNC machining process offers a variety of capabilities and operations, the fundamental principles of the process remain largely the same throughout. 

  • Designing the CAD model
  • Converting the CAD file into a CNC program
  • Preparing the CNC machine for the process
  • Executing the machining process

Let's not forget that choosing the right CNC machine is crucial for the correct progress of the process.
