Grinding Machine. A grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool.; These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips mm.

A CNC milling machine consists of the machine base and moving axes, a computerized controller, and some form of spindle to rotate the cutter or part. These machines are run from data either programmed in by hand, or created by a CAD/CAM system. There is a lot of variety in the types of machining, and types of machines. One should

Rolling is the most important metal forming process. More than 95% of ferrous and nonferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. and Fig.

Casing Section Milling. One of the main reasons limiting the use of rigless PA operations is poor casing cement or uncemented casing. For conventional practice, a window is section milled and the operation is called section milling. The aim of section milling is to grind away a portion of casing and cement.

ensure that the grains have the optimum moisture content before milling. If the grain is too dry and hard, it is difficult to break down and requires more energy to convert it into flour. If the grain is too moist, the material sticks to the mill. The optimum moisture content varies between cereal types and with the particular mill being used.

The limitations of machining process are as follows. The accuracy of the components produce is dependent on the efficiency of the operator. Consistency in manufacturing is not present. Hence inspection of the component is required. The personal needs of the operator are reducing the production rates.

Regardless of the type of machining operation, some basic types of chips or combinations of these are found in practice (Fig. ). Continuous chipsare formed by continuous deformation of the workpiece material ahead of the tool, followed by smooth flow of the chip along the tool face. These chips ordinarily are obtained in cutting duc
