What Is Computer Numerical Control Used For?

Computer numerical control (CNC) machines provide an innovative way to manipulate machine shop tools. CNC technology permits the manufacturing of mechanical parts with the use of software designs. 

CNC machines were originally developed in the mid-20th century. They have vastly improved in terms of power and precision since then.  

How a CNC Machine Works 

A CNC machine provides a way to remove elements from a larger piece of material in order to craft a specific mechanical part. These machines are useful for crafting parts from a range of materials, including metals, plastics, and wood.

A CNC machine communicates with a digital interface to gather the information it needs to form the desired piece. This digital control and design allow engineers to specify the desired dimensions with incredible specificity. 

Benefits of a CNC Machine

Programming a computer to control the specifics of a manufacturing project increases both efficiency and accuracy. This technology also decreases lead times and labor costs significantly. 

Standard machining requires many different tools to realize the desired outcome. With CNC technology, many of these standard tools can be combined.  

Types of CNC Machines

Not all computer numerical control machines are created equally. Early versions of this technology allowed engineers to design along only two axes. At RJM Manufacturing, we are equipped with 3-axis, 4-axis, and 5-axis CNC capabilities. 

3-Axis Machining

This type of CNC involves implementing a three-dimensional design along the X, Y, and Z axes. This type of digital machining is one of the most standard and reliable approaches to parts manufacturing today. 

4-Axis Machining

This advanced technology allows engineers to implement designs along the A axis. This fourth axis rotates around the Z axis. 4-Axis CNC is useful for making adjustments to the side of a piece. 

5-Axis Machining

In addition to the four axes discussed above, 5-axis CNC can implement designs along the B axis. The B axis rotates around the Y axis and allows components to be adjusted from five different sides at once.  

With CNC technology, the engineers at RJ Manufacturing can implement any design with high degrees of speed, efficiency, and precision.
