Understanding Key Parameters of Precision CNC Machining

Understanding Key Parameters of Precision CNC Machining

When you engage a machine shop to handle your contract manufacturing and/or prototypes to production manufacturing project, it is a good idea to discuss your expectations while gaining an understanding of the overall manufacturing process. Several parameters must be monitored achieve precision in CNC machining:

Feed Rate

The feed rate refers to the speed at which the cutting tool moves along the workpiece during the manufacturing process. The feed rate must be set at an appropriate level to avoid damaging the workpiece.

Spindle Speed

The spindle speed refers to the rotational speed of the spindle holding the cutting tool. Spindle speed must be set at an appropriate level to achieve the desired surface finish and avoid excessive tool wear.

Cutting Depth

This refers to the amount of material removed per pass. An inappropriate cutting depth can lead to tool wear and damage the workpiece.

Tool Type

The selection of the tool type is essential in achieving precision as different tools have unique properties that must be considered.


Proper Computer-Aided Design (CAD) is essential in ensuring the CNC machine is well-prepared for the manufacturing process. CAD procedures include optimizing the design parameters to match the capabilities of the CNC machine, selecting the appropriate cutting tools, and programming the machine’s correct settings.
