Because of the complexity, large ambiguities and disagreements, and also lack of proper understanding of the mechanism of retardation, no fundamental and universally accepted model is available that would include all the mechanisms and could be applied to all materials.

The material composition of High Speed Steel (HSS) is high carbon tool steel with a typical composition of 18% tungsten, 4% Chromium, 1% Vanadium, 0.7% carbon.
However increasing the rake angle to the large value reduces the tool material available at the tool tip for conducting heat generated, thus increasing the tool tip temperature and this would decrease tool life (Taylor equation).
In order to prove the optimal prediction result, the confirmation test (Real machining) was carried out onto AL6061 with 2mm depth and found 0.01771µm of tool wear References [1] Yung-Chang Yen, Jörg Söhner, Blaine Lilly, Taylan Altan, Estimation of tool wear in orthogonal cutting using the finite element analysis, Journal of Materials Processing Technology 146 (2004) 82–91 [2] P.S.

This study presents a new mathematical model for determining the specific growth rate of biomass in biotechnological production processes, which aims to optimize the production of biotechnological products such as the advanced material polyhydroxyalkanoates.
Especially in research, material consumption, laboratory time and costs can be reduced compared to the established model.

These factors include the parallel capacitance of the converter, depositing dielectric materials on the sidewalls of the converter fingers and increasing the thickness of the converter moving plate.
Finally the effect of combining both increasing the device thickness and depositing dielectric materials on the output power will be explained.
Increasing The Output Power By Depositing Dielectric Materials On The Sidewalls of The Converter Fingers In order to increase the output power, Cpar must increase and α must decrease.
Thus one can conclude that depositing dielectric materials on the sidewalls of the converter fingers increases its output power as it increases its maximum capacitance.
