This document from Sorotec is quite useful: [http://www.sorotec.de/webshop/Datenblaetter/fraeser/schnittwerte.pdf Sorotec Cutting Speeds]. But beware! These values are a rule of thumb and we might not be able to reproduce the results on our machine! | |||
Yet another word to datasheets: The values are usually given for a tool's lifetime of 15 minutes! Yes, you read right only fifteen minutes! If you want to keep for cutters for a longer time, then do not use those values. | |||
A rule of thumb is the following: The lower the Youngs modulus (E-Module) of a material, the sharper the tools must be, a more rigid setup is required, heavy feeds and slow speeds produce better results and abundant cooling is required. | A rule of thumb is the following: The lower the Youngs modulus (E-Module) of a material, the sharper the tools must be, a more rigid setup is required, heavy feeds and slow speeds produce better results and abundant cooling is required. | ||
