Please note that by downloading you agree to use this calculator entirely at your own risk. The speeds and feeds suggested must be modified to suit the capabilities and limitations of your  own milling machine.

    Calculator in Excel format (for Windows OS and Mac OS)

  

Notes:

The Excel file is in .xls format so should be compatible with older versions of Excel.

This file can also be opened by Apache Open Office, which will work on Windows, Mac and Linux OS.

Apache Open Office is a free download from The Apache Software Foundation. It is “Open Source” software and has been around for a long time under a different name. It is supported across the three different operating systems and platforms listed above.

Apache Open Office can be downloaded from here.

If you need a calculator file in native Open Office format, send me an email (see Contacts page).
