General Machining Guidelines Using the data tables and the milling formulas below, you can calculate the speeds and feeds of any carbide end mills and diamond end mills. Are you using a Harvey tool?
Cutting speed. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Calculate Speed and Feed for Turning Applications. These calculations are based upon theoretical values and are only intended for planning purposes.
