in this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the sic abrasive slurry and al2o3, use of diamond paste as abrasive tool) in magnetic abrasive finishing process using designing of experiments on the external surface of cylindrical work pieces of stainless steel aisi 440c to get minimum surface roughness has been...

This paper analyses the fracture behavior of the brazed BCBN grain by comparison with brazed PCBN grain through grinding test of Nickel-based superalloy. The self-sharpening effect is created by timing micro-fracture behavior for BCBN abrasive grains, but by macro-fracture behavior for PCBN abrasive grains. During grinding with brazed BCBN abrasive grains, the material is removed together with ...

Magnetic abrasive machining is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible. The aim of this paper is to study maximum efficiency in terms of material removal rate with respect to magnetic flux density ...

The paper solves the problem of the nonexistence of a new method for calculation of dynamics of stress-deformation states of deformation tool-material systems including the construction of stress-strain diagrams. The presented solution focuses on explaining the mechanical behavior of materials after cutting by abrasive waterjet technology (AWJ), especially from the point of view of generated su...

Friction and abrasive surface treatment of engineering steels is the new effective tool for surface material strengthening and improving the resistance to fatigue damage. The specific abrasive machining of medium-carbon steel yields formation of surface hardened layer with super dispersed nanocrystal structure which increase the fatigue damage resistance in times. The present study aimed to est...

In this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. This mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (MAF) process. A permanent magnet which is mounted on a horn has been used as the processing tool. This polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. Ultrasoni...

The axiomatic design theory is applied with the product design knowledge expression of abrasive machine tools, making it possible to convert the implicit knowledge created in the study process into the explicit knowledge that will be shared all over the organization. The design knowledge created in the design and developing processes is divided into functional requirements, design parameters, d...

In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...
