Stainless steel is one material that hardens very easily under cold working, therefore insufficient feed rate or incorrect spindle speed can lead to less than ideal cutting conditions as the work piece will quickly harden and resist the tool's cutting action. Use these charts for carbide tipped milling cutters. Some materials can be cut at a wide range of spindle speeds, while cutting speed is critical to some materials like stainless steel, it’s easy … MADE … Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Feed must be maintained as the tool enters the work-piece. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. It’s easy to run one at what may seem a sane Feed and Speed and have heat gradually build up until the tool is ruined.

Keyseat Cutter Speeds and Feeds. Use higher speeds and feeds for easy-to-machine materials. TIP: Reamers should generally be run at half the spindle speed and twice the feed per revolution of the equivalent sized drill bit. Form turning stainless steel should allow sufficient material to be removed to avoid surface work hardening problems. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated. For general profiling I like Maritool variable flute endmills and his speed feed chart is pretty well spot on. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based … feed per tooth for large cutters in aluminum workpieces. Feeds and speeds are starting recommendations only. Factors such as machine, fixture and tooling rigidity, horsepower available, coolant application and others will affect the performance significantly.
