Abstract: Grinding is the machining processes which improve surface quality and dimensional accuracy of the work piece. Various process parameters, which affect the cylindrical grinding operation, are depth of cut, material hardness, work piece speed, grinding wheel grain size, number of passes,

waviness) of machined parts are directly determined by these characteristics, as well as by the machining regimes/parameters selected, machine tool dynamics, cutting-tool material and geometry, and cooling fluid. As revealed, out of these variables, adequate and optimal cutting parameter selection plays the most significant role.

The cylindrical grinding machine i.e. CGM faces a no. of various types of disturbances for example; temperature drifts, tool wear, path control deviations and much more factors and due to these factors there will be losses in productivity as well as there will be dimensional deviations also in work piece.

However the machining of ceramics is very expensive and time consuming operation representing from 50 to 90% of the total cost of the part. The main parameter of the efficiency of a machining operation is the Material Removal Rate (MRR) indicating the volume of the material removed from the workpiece surface for 1 min.

PARAMETERS OF GRINDING OPERATION Major process parameters which are most commonly used in grinding process are machining speed, feed rate and depth of cut. 9.1. Cutting Speed It is the comparative peripheral angular velocity of the abrasive grinding wheel with respect to the work material.

There is a need to investigate on component based process. To analyse several machining operations like facing, grooving, threading and turning.

Different Types of Machining Operations. "Two primary machining processes are turning and milling – descried below. Other processes sometimes dovetail onto these processes or are performed with standalone equipment. A drill bit, for instance, may be installed on a lathe used for turning or chucked in a drill press.

1. Cannot be used unless the machine has a backlash eliminator and the table jibs have been tightened 2. Cannot be used for machining castings or hot rolled steel, since hard outer scale will damage the cutter. Grinding Grinding is the most common form of abrasive machining. It is a material cutting process that

effectively machine all materials whether they are electrically conductive or insulator. For an effective cutting operation, the following parameters need to be carefully considered: The machining tool must be selected to be highly wear resistant, such as high-carbon steels.

Influencing parameters include all those parameters that can directly or indirectly influence the machining operation. Thus all process parameters are influencing parameters. Apart from velocity, feed and depth of cut, there are many other parameters that can influence performance considerably; however, they are not inherent to machining process.

Figure 2 shows the grinding of a specimen when it is fitted on chuck subjected to high speed grinding wheel which is assisted with coolant system to meet better accuracy and finish.

For example, the machining center chip-breaking peck drilling cycle (G73) has a parameter that controls retract amount between pecks. The larger this value, the more time it will take to machine a hole. In similar fashion, the deep-hole pecking cycle has a parameter that controls the clearance amount between pecks.
