Lecture 8. Metal Cutting
for hard, brittle workpieces. Grinding is also used to machine brittle materials (such materials cannot be machined easily by conventional cutting processes, since they would fracture and crack in random fashion). The main uses of grinding and abrasive machining: 1. To improve the surface finish of a part manufactured by other processes Examples:
Metal forming processes - IIT Guwahati
Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process. Plastic deformation: Stresses beyond yield strength of the workpiece material is required.

Screw Spike - an overview | ScienceDirect Topics
A numerical model of the CWR process for the screw spike thread has been designed with the use of the DEFORM-3D v.6.0 software. To shorten the calculation time, it has been assumed that screw spikes are formed with symmetrical tools (such assumption being true if one screw with a left-hand thread and one screw with a right-hand thread are formed simultaneously).

About Thread Rolling: Machines, Materials, and Process
If a thread-rolling machine is used, the unthreaded screw, bolt, or other "blank" is placed (either automatically or by hand) between dies having thread-shaped ridges that sink into the blank, and by displacing the metal, form a thread of the required shape and pitch. The thread-rolling process is applied where bolts, screws, studs ...
Forming Process: Definition, Classification or Types ...
Forming Process also known as Metal Forming is a large set of the manufacturing process by which a raw material converted into a product. In this process, we apply stresses like tension, compression, shear, etc. to deformed the raw material. The example of forming processes are sheet metal manufacturing, forging, rolling, extrusion, wire drawing, thread rolling, rotary swinging, and so on.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
