speed aircraft. This led to the development of computer-based automatic machine tool controls also known as the Numerical Control (NC) systems. Commercial production of NC machine tools started around the fifties and sixties around the world. Note that at this time the microprocessor has not yet been invented. Version 2 EE IIT, Kharagpur 5
Grinding Grinding is the most common form of abrasive machining. It is a material cutting process that engages an abrasive tool whose cutting elements are grains of abrasive material known as grit. These grits are characterized by sharp cutting points, high hot hardness, chemical stability and wear resistance.

machine tool operator. At the beginning of the job, the operator must move the cutting tool under manual control to some target point on the worktable, where the tool can be easily and accurately positioned. The target point has been previously referenced to the origin of the coordinate axis system by the part programmer. When the tool has

Grinding side 3 Rotate Tool Approx. 15° Grind until sparks just reach tip of tool A B FIGURE 9—Grinding the "Hook" into side 3. When grinding tools by hand, on average, the cutting-tip surface of the tool is going to be .005" to .0010" below the top of the tool. This will leave a .010" to .020" tit on the end of your tool when facing

tool point of the cutter moves with respect to the work measured in feet per minute. Feed is the rate at which the work moves into the cutter measured in feed per tooth revolution. Feeds and speeds affect the time to finish a cut, tool life, finish of the machined surface and power required of the machine.
Abrasive grinding is still a key method of efficiently and accurately shaping workpieces, especially those made of difficult-to-machine construction materials with high hardness and strength, e.g., titanium, magnesium alloys, nickel and cobalt-based superalloys, Inconel, etc. [1,2,3].The increasing requirements for modern manufacturing processes in the field of: dimensional accuracy, surface ...
A machine tool is a machine for shaping or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing or other forms of deformation. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine.

A major problem with aligning machine tools using conventional methods is that many different alignment tools must be used, requiring a lot of time and increased stack-up errors. An alignment is only as good as the tools used to perform it. The machinist level, for example, has a resolution of .0005" per foot, which is not very
