Cutting-Tool Materials and Cutting Fluids

The reasons for the availability of a large variety of cutting-tool materials is best appreciated by reviewing the top eight parameters in the first column in Table 22.2 on p. 638. Among various factors, the type of workpiece material machined, the type of operation, and the surface finish and dimensional accuracy required all affect the choice of a cutting-tool material. For example, for inter...

Cake Cutting ∗

In the 2nd world war, if you’re a collection of Polish mathematicians sitting out the war in Lvov, your thoughts naturally turn to ... cake. Or more precisely, how to cut a cake. This is the beginning of what we now call the problem of “fair division”. Fair division algorithms are examples of what we might now call a mechanism, much like an auction. These are protocols designed to allocate reso...

Investigation of Cutting Forces Superalloy Inconel 718

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

LASER CUTTING PARAMETERS The laser cutting parameters are dependent on the beam characteristics, the cutting rate

The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that a...
