How calculate the gripping force on lathe chuck

I have a problem with the calculation of the correct clamping force to tapping the pipe fi=40x6 mounting with lathe chuck in three jaws. The torque to tappe the pipe was 25 Nm and rotation speed was 72 rpm.

if you studied the machining processes then calculate the cutting force which a tool exert on the work part.then there will be friction so adding the both force ,it will be the net force.hence it will be required by the chuck.you can yous pro-e/solidworks 2012 or catia to help out your calculations

You can see how to calculate it on this site:

In my studies I don't have a subject about machinig processes. I never work in Catia, ProE/Solid Work. My work tabel was Autodesk Inventor but this program don't have the function to calculate the gripping force. Thank you for your answer.
