Detroit, Michigan. In Detroit, Norton had gotten idea to expand the grinding machine's capabilities so that it could utilize a wider abrasive wheel. In 1990, Norton founded the Grinding Machine Company at Massachusetts. In 1919, cylindrical grinding machine had become a standard machine tool .
Grinding is the machining processes which improve surface quality and dimensional accuracy of work piece.  There are various process parameters of a cylindrical grinding machine that include grinding wheel speed, work piece speed, table feed, depth of cut, material hardness, grinding wheel grain size, no. of passes and material removal rate.

assumption that a speciﬁc grinding process instability is present. Some researchers (2–4) have considered the general problem of the stability of the cutting process using a model based only on the variation of the uncut chip thickness as a result of the elastic deformation of the machine tool and workpiece system.

Fig. 5 Cross section of the uncut chip in tangential turnmilling. Line 12 represents the initial position of the tool whereas line 13 represents its final position after a rotation of degree around the workpiece.
In peripheral wheel grinding, uncut chip thickness is a function of wheel diameter, depth of cut, feed rate ( ratio of wheel speed to table surface speed), and grit spacing. ... and amplitudes given by the dynamic performance of the machine.
In the dry grinding process, as there is no coolant lubricant to transfer the heat from the contact zone, minimizing the grinding specific energy and grinding forces is a matter of importance. Some of the results of the systematic research works, based on a novel concept to make a step forward for pure dry grinding, are presented.

We named this book Handbook of Machining with Grinding Wheels because the borders between grinding and other operations such as superfinishing, lapping, polishing, and flat honing are no longer distinct. Machining with grinding wheels extends from highremoval rate processes into the domains of ultrahigh accuracy and superfinishing. This book

Grinding is most productive when all the elements of the system have been selected to work well together. Some of the elements to be considered are the grinding machine, the grinding wheel, the workpiece, the grinding fluid, the atmosphere, and the grinding swarf. Another is the wheel dressing tool. Figure Elements of a basic grinding system.
Grinding Wheel Speed If we increase the grinding speed the uncut chip thickness experienced by a grit decreases. increases the grinding ratio. . Naturally the grit will remain on the grinding wheel till the force is high enough( after some wear) to pull out the grit. Thus increasing the wheel speed. Hence the forces coming on the grit decrease.
