As regards its importance it is second only to the lathe machines.Holes were drilled by the Egyptians in 1200 B.C. about 3000 years ago by ...
A number of diverse methods can be used for gathering evidence to identify the mechanisms of abrasive-workpiece interactions. One possibility is to examine the grinding debris (swarf) produced by the process in order to theorize how it could have been produced. For this purpose, the scanning electron microscope (SEM) is an invaluable tool.

This machine is based on the mechanism of whit worths return. This model of the multi operational machine may be used in industries and domestic operations, which can perform mechanical operations like Drilling, cutting and shaping of a thin metallic as well as wooden model Or body. Problem Statement
To design a low weight grinding machine that can easily be installed in individual houses mainly in rural sides. To reduce human effort over operating this. To reduce time consumption by the overall process. To use simplicity in the mechanism used, so that rural people can use it with ease.
Grinding is a combination of rubbing, ploughing and cutting (actual chip formation) . A certain level of grit penetration into workpiece is required before chip formation can start. Magnitude of critical grit depth of cut required to initiate cutting becomes less with the increase of grinding velocity.
In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. So when we start the electric motor the motor rotates at a certain rpm (150-15000 RPM, it may change according to the types of grinding machine) with the help of v-belt and cone pulley the grinding wheel also starts rotating and we perform the operation.
important that the part transfer mechanism should work efficiently. For efficient working of the part transfer mechanism, the factors affecting the mechanism and the environment in which it is working should be considered while designing. 1.1 ALFING machine ALFING is an induction hardening machine used to harden crankshafts.
traverse mechanism (see Figure 1). The traverse mechanism allowed the magnetic chuck to horizontally move under the grinding stones, which were mounted directly above the chuck. The grinding stones were adjusted by turning a large wheel on the side of the machine, allowing the operator to adjust the cutting depth to 1/100 of an inch.
Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several

Drilling Machine is the simplest, moderate, and most accurate machine tool used in almost all the production shops and tool rooms. Drilling is basically a single purpose machine tool as its main purpose is to make holes in the workpiece.
Drilling Machine It is a machine which is used to drill the holes on the components or workpiece with the help of drill bits. The drill bits are also called as Multi-point cutting tools which can have their rapid impact on the Material Removal Rate (MRR) i.e. a single-point cutting tool (like the one used in a lathe machine) can remove the material slowly whereas, a multi-point cutting tool ...
Milling Machine Definition The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
