CNC Machining

What is CNC Machining?

CNC machining is a term commonly used in manufacturing. CNC stands for computer numerical control. CNC machining is a manufacturing process which typically uses computerized controls and machine tools to remove layers of material from a stock piece to create a custom-designed part.

A CNC machine is a programmable machine that is capable of autonomously performing the operations of CNC machining.

Machining is a manual (non-computerized) manufacturing process of removing material from a workpiece using power-driven machine tools to shape it into an intended design. Most metal components and parts require some form of machining during the manufacturing process. Other materials, such as plastics, rubbers, and paper goods, are also commonly fabricated through machining processes.

 

 

What CNC Machinists Do

  • Measure, examine, or test completed units to check for defects and ensure conformance to specifications
  • Set controls to regulate machining
  • Maintain industrial machines, applying knowledge of mechanics, shop mathematics, metal properties, layout, and machining procedures
  • Calculate dimensions and tolerances using knowledge of mathematics and instruments 
  • Select the appropriate tools, machines, and materials to be used in preparation of machinery work
  • Monitor the feed and speed of machines during the machining process
  • Set up, adjust, and operate all of the basic machine tools 
  • Measure dimensions of finished workpieces to ensure conformance to specifications
  • Remove and replace dull cutting tools
  • Mount, install, align, and secure tools, attachments, fixtures, and workpieces on machines
  • Adjust machine feed and speed, change cutting tools, or adjust machine controls when automatic programming is faulty or if machines malfunction
  • Stop machines to remove finished workpieces 
  • Modify cutting programs to account for problems encountered during operation 
  • Calculate machine speed and feed ratios and the size and position of cuts
