Grinding is the most common form of abrasive machining processes. It “is a material removal process accomplished by abrasive particles that are contained in a bonded graining wheel rotating at very high surface speeds.” The tool used in grinding is called the wheel and “consists of abrasive particles and bonding material. The bonding material holds…
Contact ratio is average number of gear teeth in contact with one another as the gears are in operation. Gear tooth profiles must be dimensioned in such a way that more than one pair of gears must be in contact with one another. This insures smooth and quiet operation of the gear pair. The formula…
Milling and Turning Basics: Milling is the process of cutting away material by feeding a workpiece past a rotating multiple tooth cutter. The cutting action of the many teeth around the milling cutter provides a fast method of machining. The surface may also be milled to any combination of shapes. There are two main types…
