Abrasive flow machining (AFM) is very effective and widely adopted superfinishing process of internal channel surfaces in industry. There have been high demands for monitoring surface roughness evolution during AFM, as the sensitive to AFM medium variables, such abrasive grain size concentration, well duration. Acoustic emission (AE) known be a promising tool detect microscale deformation mecha...

Knowledge of the hardness of abrasive particles that are used in polishing is a key to the fundamental understanding of the mechanisms of material removal. The magnetorheological-finishing process uses both magnetic and nonmagnetic abrasive particles during polishing. The nanohardnesses of the micrometer-sized magnetic carbonyl iron and nonmagnetic abrasive particles have been measured successf...

As a new manufacturing process, abrasive water jet (AWJ)cutting has been very effective for difficult-to-machine materials. From the point of view of jet generation, abrasive water jets can be categorized as injection jeti or suspension jets. Injection jets are the most commonly used type for practical applications. An injection AWJ is formed by accelerating small abrasive particles through con...

Original scientific paper In this paper, the results of investigations of the temperature field distribution and tool wearing during C60 steel turning are presented. Abrasive wear resistance tests were carried out for cutters made of low-alloy high-speed steel. Steel samples were heat treated, and then were subjected to ion nitriding, TiN coating, or to complex treatment. The influence of cutti...

In the present research work, the effect of several process parameters on the machining characteristics of pure titanium (ASTM Grade-I) has been reported. The machining characteristics that are being investigated are tool wear rate and the quality of the machined surface in terms of the surface finish. The mechanism of material removal was has also been correlated with the machining conditions....

This study concerns the determination of the significant factors for an innovative deburring process: low pressure abrasive water-jet blasting. We firstly classify the abrasive medium aluminum oxide (Al2O3) according to the individual characteristics of different grain sizes. Then, the particle behavior in the air jet is analyzed with an optical measuring method, Particle Image Velocimetry (PIV...

OBJECTIVE To evaluate the air powder abrasive treatment as an implant surface cleaning method for peri-implantitis based on the existing literature. MATERIALS AND METHODS A PubMed search was conducted to find articles that reported on air powder abrasive treatment as an implant surface cleaning method for peri-implantitis. The studies evaluated cleaning efficiency and surface change as a resu...
