Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining carried out on a so-called ‘green ceramic’: compact composed powder held with help binder. This difficulty due not only to composition material, but also lack methods that determine optimal parameters. The goal this paper apply method based ductile material behavior fee...

During machining of stainless steels at low cutting -speeds, workpiece material tends to adhere to the cutting tool at the tool-chip interface, forming built-up edge (BUE). BUE has a great importance in machining processes; it can significantly modify the phenomenon in the cutting zone, directly affecting the workpiece surface integrity, cutting tool forces, and chip formation. The American Iro...

In this research work the tool-chip interface temperature is measured experimentally during turning of EN-31 steel alloy with tungsten carbide inserts using a tool-work thermocouple technique. First and secondorder mathematical models are developed in terms of machining parameters by using the response surface methodology on the basis of the experimental results. The results are analyzed statis...

Database system is mainly created for superhard cutting. In the paper, the processing time is considered as the objective function based on the issue needs, the establishing of the mathematical model of the cutting database system mainly takes cutting force, power tools, precision machining and tool life as constraints. And the database develops through the development software VS2008 and SQL S...

High speed machining of hardened steels for manufacturing dies and molds offers various advantages, but the productivity often limited by mainly tool life. This study investigates the influence of edge preparation in cubic boron nitrite (CBN) cutting tools on process parameters and tool performance by utilizing practical finite element (FE) simulations and high speed orthogonal cutting tests. T...

Chatter vibrations, occurring during cutting process, cause vibration between the cutting tool and workpiece, which deteriorates surface roughness and reduces tool life. The purpose of this study is to investigate the influence of cutting parameters and tool construction on surface roughness and vibration in turning of aluminum alloy AA2024. A new design of cutting tool is proposed, which is fi...

Abstract Ceramic matrix composites have high hardness, so their machining requires grinding forces that cause severe wear of the head. To investigate this problem, present study investigated cutting performance conventional (CG) and laser-assisted (LAG) SiC f /SiC ceramic using electroplated diamond heads. Firstly, a three-dimensional transient heat transfer model based on Gaussian source was d...
