Dec 09, 2016018332The operation is performed by the face milling cutter mounted on stub arbor of the machine. 2. Side Milling. It is the machining process which produces flat vertical surface at the sides of a workpiece. This operation is performed by using side milling cutter. 3. Plain MillingRead More
the main purpose is effective material removal. Each specific application must of course be looked at sepa-rately. Grinding sharp edges for instance, naturally requires a hard bond that wont be worn out instantly. A softer bond is needed if the material being worked on is soft or malleable. Figure 9 Grain Bonding Porf Workpiece Cuttings ...Read More
Grinding, once considered primarily a finishing operation involving low rates of removal, has evolved as a major competi-tor to cutting, as the term abrasive machining suggests. This is what Milton Shaw, the man who is considered the great pioneer and father of American grinding, said about 10 years ago.Read More
The grinding ratio is the proportion of the volume of removed workpiece material to the volume of abrasive wear, which reflects the cutting efficiency of the grinding wheel. The grinding ratio decreases with the increase in the number of grinding passes, as shown in Figure 9 a. This is attributed to the weakening of the grinding performance of ...Read More
different grinding operations. STOCK REMOVAL RATE When grinding, the amount of chips removed per unit of time can most easily be expressed as mm3s. This is often referred to as the stock re-moval rate, and depends on the ma-chine feed, the composition of the grinding wheel, its cutting speed peripheral speed and in certainRead More
