Bearing Life Calculation

e = 3.0 for ball bearings, 10/3 for roller bearings; Combined Radial and Thrust Loads. All ball bearings, tapered roller bearings, and spherical roller bearings are capable of taking a significant axial thrust load. The “equivalent bearing load”, P, used in the rating life formula, needs to be calculated when combined radial and axial loads ...

Milling Speed and Feed Calculator

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
