Technology Overview

What is CNC Machining

About the CNC Process

CNC, or computer numerical control machining, is a subtractive manufacturing method that leverages a combination of computerized controls and machine tools to remove layers from a solid block of material. The desired cuts in the metal are programmed according to corresponding tools and machinery, which perform the machining task in an automated fashion.

Types of CNC Machining

Depending on the type of part that needs to be machined, there are different types of CNC machines best fit for the job. CNC mills consist of a multi-axis system (three, four, or five axes, depending on the part complexity). Lathemachines generally have 2 axes and cut pieces using a circular motion. Electric discharge machines (EDM) utilize electrical sparks into order to mold work pieces into the desired shape. Hobbing is another type of machining process used for cutting gears, splines, and sprockets. Additional machining types include plasma cutters and water jet cutters.

CNC vs 3D Printing

Compared with parts manufacturing through additive methods, CNC machined parts are functionally stronger and typically have superior production quality and finish. Thus, CNC machining is typically used in the mid to late stages of development when parts are ready to be tested for functional accuracy.

CNC Design Considerations

While most of the details, such as tooling, spindle speed, cutter type, and depth of cut, and taken care of at the machine shop, there are some key things you can do while designing your parts to not only make sure they can be made, but also ensure you develop a lean product that doesn't break the bank.
