Speed and Feed Calculator Kennametal

Speed and Feed Calculator Kennametal

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.
