ur thhe spécific for shear, u, and the specific heat of the material. Hence, temperature risc ene machining materials with high strengt cates. The temperature rise at the tool-chip interface is, of course, also a fiu cocfficient of friction. Flank wear (see Section 8.3 and Fig. 8.20a) isction of source of heat, caused by rubbing of the tool on the machined surface. those of the workpiece. generated in the shear plane is a functioll UI material. Hence, temperature rise is...

Composites are materials that are made by embedding a fiber, such as glass or carbon, inside a matrix, such as a metal or a ceramic. Composites are used in engineering structures, and their degradation when subjected to wheather conditions is an important issue.. In an experiment to investigate the effect of the moisture on a certain kind of composite, the weight gains of a collection of n=25 samples of composite subjected to water diffusion were obtained. The sample mean is...
