摘要

基于固定弯曲尖端工具的磁流变精加工技术在精加工外圆柱形表面时效果较差。因此，利用工件和工具的旋转，开发了基于三旋转平尖工具的磁流变精加工工艺，以解决现有方法的问题。此外，还建立了一个进给机构，以提供工件的纵向运动。用开发的和现有的方法对一个低碳钢工件进行了精加工。结果表明，静刀加工1小时30分钟后，表面粗糙度值Ra、Rq和Rz分别降低了69.29%、64.41%和61.26%。而在相同参数和条件下，三种旋转扁头刀具加工完成后，表面粗糙度值Ra、Rq和Rz分别降低了85.38%、84.51%和82.7%。

A novel magnetorheological finishing process based on three revolving flat tip tools for external cylindrical surfaces

The magnetorheological finishing technique based on a stationary curved tip tool is found less effective in finishing external cylindrical surfaces. Therefore, three revolving flat tip tools-based magnetorheological finishing process which utilises the rotation of both workpiece and tools have been developed to address the issues of the existing method. Also, a feed mechanism has been built to provide the longitudinal movement to the workpiece. A workpiece of mild steel has been finished by both developed and existing methods. It has been observed that after finishing 1 hour 30 minutes with a stationary curved tip tool, surface roughness values Ra, Rq, and Rz decrease by 69.29%, 64.41%, and 61.26%, respectively. Whereas, the reduction in the surface roughness value of Ra, Rq, and Rz by 85.38%, 84.51%, and 82.7%, respectively, have been noted after finishing with the three revolving flat tip tools process at the same parameters and conditions.
