For complex curved difficult-to-machine parts, a new method based on pneumatic suspension abrasive pool bright finishing processing is proposed, using the mixing of abrasive, workpiece surface, and fluidized to produce relative motion velocity, so that solid particles surface microscopic two-body wear achieve effect precision machining. The experimental test material widely used Q235 steel plat...
This paper proposes a novel magnetic abrasive finishing (MAF) process that uses an auxiliary machining tool for the internal surface of thick-walled tube. The and external poles form closed field circuit. Thus, stronger force can be generated during process. In current study, we focus on analyzing distribution flux density investigating characteristics mixed speed relative revolutions. Based ch...
If one of the surfaces which are in touch is rough and hard, it chips the other surface due to relative motion or touching forces. The wear is called two-body abrasive wear. If there are free abrasive particles between the two bodies, the wear is called three-body abrasive wear. The free abrasive particles may be external material dust or the remains of chipping. Usually, the wear starts as a t...
This study proposed a new magnetic abrasive finishing (MAF) method, in which 6-axis robot with machining tool was used to polish the inner surfaces of curved tubes. We have also developed jig, can be fixed at front robot, rotating freely and suitable for polishing In this study, we focused on investigating parameters initial stage precision stage. Based characteristics parameters, multi-stage M...
the plain carbon steel “ck45” has relatively well mechanical and metallurgical properties and low cost. the purpose of this research was the property evaluation of this steel on abrasive wear and impact for using in plows and other tillage tools. tillage tool should resist in abrasive wear and impact simultaneously. several heat treatments were done on specimens of this steel. a standard test d...
