In Grinding, geometrical irregularities called surface texture and surface integrity are normally controlled. To obtain a good surface texture and better surface integrity, depends to a large extend on choosing the cutting ...

Residual stresses were induced in quanched and tempered ABNT 4340 steel specimens by means of orthogonal turning operation, varying the machining parameters based on a statistical surface response design. The experiment ...

The machining can be considered a great process in the industry. Its development accompanied the evolution of the production engineering and product engineering. In consequence new tools and new machines were created. ...

Machining plays an important role in the manufacturing of mechanical parts. This work analyzes specifically the turning, which is one type of the machining processes. When it is studied the general aspect of turning, one ...

This paper presents a study about the utilization of Response Surface Methodology (RSM) in costs stochastic modeling by a turning process of a hardned steel SAE/ABNT 52100. In function of the random nature of the tool ...

The free-machining steels are known by having a good machinability due to easiness of chip formation. The characteristic of a good machinability is determined, essentially, by the chemical composition of the material ...

In the scope within in the automotive industry the machining processes are widely applied. Among them, the grinding process is widely used for finishing parts that require low roughness and dimensional tolerance, with the ...

The study on the end milling of duplex stainless steel has been gaining prominence due to the challenges encountered in its low machinability. This occurs, therefore, these materials have low thermal conductivity, high ...

Super duplex stainless steels have a mixed microstructure consisting of ferrite and austenite phases and are used especially in the oil and gas industry, but have low machinability. The helical milling process consists of ...

The large elderly population has naturally led to an increase in the number of orthopedic surgeries, such as knee and hip replacements. In developing countries, the growing demand for this type of surgery is already a ...
