Feeds and Speeds Calculator for CNC machine tools
Calculate the feeds and speeds needed for CNC cutting tools, machines and projects with our free calculator below. All you need are the speed RPM, number of flutes, material and tool diameter. CNC Router bits and CNC router tools are effective, only if used in the correct manner. If the material you need is not listed, contact us on 01329 246070 or email@example.com to let us know and we can help you find the right speed and feed for your cutting job.
If you would like any help or advice for using the calculator or what to do with your results, please get in touch with our team. The calculator is intended to be a useful guide for you to use when calculating speeds and feeds. Please remember that if you are using the higher RPM, the friction will give a better surface finish but can create more mechanical wear on the tool edge so you should always be aiming for the lowest RPM for that tool and material. If you are not sure about the result for a new tool, please get in touch with our team and we can help you to make the right decision on what speed to use with your CNC tool.
