Very hard materials can often be tricky to machine, as larger cutting forces (and thus stronger tools and more powerful machines) are required. The thermal properties of a material are also important when machining - generation of heat during the process can impact the surface finish and dimensional accuracy of the finished part.

Machinability of a metal is influenced by the machine variables (rigidity, power and accuracy of machine), tool variables (tool material, geometry and type of cut), cutting conditions (speed, feed and depth of cut) and the work material properties. How each of these variables affect machinability is discussed below.

Hard rock angle standards are primarily used to control the 90° angle. Angle standards are ideally suited for quick alignment of angles (for example for measuring machines or machine tools). The granite angle standards are made of dark hard stone. Four narrow surfaces of the angle standards are parallel to each other and lapped at right angles.

5. Angles affect success in centerless grinding. The angles at which the centerless grinding wheels contact the part are critical to achieving the proper roundness and tolerance. Generally, the centers of the regulating and grinding wheels are set at the same height on the machine, and the center of the workpiece is situated higher.

Grinding force and temperature prediction models considering grain orientation and phase transformation were established by Zhao et al. [30,31], and the influence of grain characteristics of the machined materials on the grinding properties was analyzed.

The depth of cut refers to the width of material in contact with the tool. In some machines, like the drilling machine, this is related to the speed and feed rates. In other machines, it is also dependent on the position of the tool relative to the work piece. On the grinding-type tools, the width depends on how much of the surface is being ground.

Materials scientists learn about these mechanical properties by testing materials. Results from the tests depend on the size and shape of material to be tested (specimen), how it is held, and the way of performing the test. That is why we use common procedures, or standards.

Mechanical properties may be determined to provide either design data for the engineer or as a check on the standard of raw materials [1]. Mechanical properties may be changed by heat treatment process and the working temperature. Mostly, the strength, toughness and hardness of materials are to be measured after the metal forming process [2].

the grinding machine is GMN HCS120. Some properties of the grinding machine are listed in Table 1. Grinding wheel is the most important type of tool in grinding. It is a porous body prepared by adding a binder to the abrasive, pressing, drying, and roasting. Grinding wheel material used in this experiment is aluminum oxide (Al 2 O 3).

The last category of material is soft and medium hardness materials which are machined by using Aluminum oxide abrasives. The steel is machined by using Aluminum oxide over the silicon carbide because Aluminum oxide is tougher than the silicon carbide so it is preferably used to machine steel having higher tensile strength.
