the map and the model designed by a designer and presented to a manufacturer in the form of a map is the result of his knowledge and innovation. the manufacturer, in turn, uses his best effort to produce a part accordingly. however, because of production problems and raw material, producing a precise part is very difficult and costly. one of the most important problems in this regard is designi...

the use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. laser assisted machining (lam) improves the machinability of high strengt...

this paper presents a mathematical model that could assist in measuring, monitoring and controlling tem-perature variation in cold and ‘red-hot’ metal working conditions of machining. a numerical analysis tech-nique of the temperature distribution, based on the theory of complex applied potential, was carried out using the principles of relationship analysis between the paths of heat supply in ...

machining operation is one of the most applicable processes for the manufacturing of industrial parts. usually, the quality of finished part in turning operation is measured in terms of surface roughness. in turn, surface quality is determined by machining parameters and tool geometry specifications. the main objective of this study is to model and optimize machining parameters and tool geometr...

The effect of cutting tool insert geometry has significant role for surface finish in turning operation. There are many different types of tool inserts with different tool insert geometry are used in turning operation. This paper present a logical procedure to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on three well ...

Nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. Since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. To reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

The main goal of this paper is to compensate the elastic deformations of the technological system in order to achieve maximum cross sectional accuracy and productivity of turning operation with minimum cost. This study was based on developing of mechanical adaptive system (MAS) for accuracy control by dynamic adjustment of the tool position during processing. The dynamic characteristic of compo...
