Abstract
In order to improve the plane quality of the workpiece shape accuracy, a correction abrasive finishing method is proposed. This method is used to achieve the effect of correcting the workpiece surface by changing the finishing conditions of different areas according to the profile of the initial surface, such as feed speed. In previous research, the feasibility and effectiveness of this method were proven. In this research, a theoretical analysis of this method was carried out and the extension of this method to the processing of larger planes was studied. Through a series of experiments on an aluminum plate (A5052), it was proven that the shape accuracy of the workpiece surface can be effectively corrected by accurately controlling the feed speed. The experimental results showed that the extreme difference of the workpiece can be reduced from 4.81 μm to 2.65 μm within the processed area of 30 mm by 10 mm.
Highlights
With the rapid development of electronic technology, optical technology and aerospace technology, the requirements for workpiece surface accuracy in many fields are higher and higher
In order to solve the disadvantage of a weak magnetic force when processing thick tubes, Zou et al proposed a processing method that could improve the magnetic force and made it possible to process the inside of thick non-ferromagnetic tubing [6]
Because the magnetic brush formed in the magnetic field has a certain flexibility and can conform to the shape of the workpiece, it is applied to the processing of various irregular shapes, such as the inner and outer surfaces of a tube, irregular surfaces, and so on
Summary
With the rapid development of electronic technology, optical technology and aerospace technology, the requirements for workpiece surface accuracy in many fields are higher and higher. For these components, their surfaces are required to be smooth, have low roughness, and have high geometric accuracy. The magnetic abrasive finishing (MAF) process is an important non-traditional finishing process [1,2]. Shinmura et al proposed and designed a plane MAF device, analyzed the process principle of plane MAF, and discussed the effect of the supply weight of finishing fluid and magnetic abrasion on the finishing depth and surface roughness [4]. Mulik et al employed ultrasonic vibration in the horizontal direction of the workpiece using an ultrasonic power, a piezoelectric transducer, and a horn device [9]
