    Milling Speeds and Feeds

    Uploaded by

    irina
    This document provides guidelines for recommended milling speeds and feeds for various materials when using solid carbide end mills, including both coated and uncoated options. It lists materials such as aluminum, steels, cast iron, stainless steel, titanium and others along with their appropriate speed and feed rate ranges based on end mill diameter and the material's hardness. Coatings including TiN, TiCN and TiAlN are recommended as first, second or third choices for certain materials to improve tool life and surface finish.
