Process capability compares the output of an in-control process to the specification limits by using capability indices.The comparison is made by forming the ratio of the spread between the process specifications (the specification "width") to the spread of the process values, as measured by 6 process standard deviation units (the process "width").
A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

Preparation of abrasive and/or super-abrasive grinding wheels includes the following operations: • Ringing. Check the integrity and structural uniformity of a new abrasive wheel. • Mounting. Consists of clamping the abrasive wheel between plane-parallel flanges and the subsequent mounting on a spindle.
Before attempting to select a grinding wheel for a particular operation, the operator should consider the following six factors for maximum productivity and safe results: Material to be ground. If the material to be ground is carbon steel or alloy steel, aluminum oxide wheels are usually selected.
Grinding is a combination of rubbing, ploughing and cutting (actual chip formation) . A certain level of grit penetration into workpiece is required before chip formation can start. Magnitude of critical grit depth of cut required to initiate cutting becomes less …
Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
Place magnetic parallels around the workpiece to ensure the workpiece does not shift during grinding. Turn the magnetic chuck on to secure the pieces onto the bed. Adjust the bed and saddle position to center the stock below the wheel. Lower the wheel an inch above the workpiece. Take a piece of paper and place it between the wheel and the stock.
