Material removal by slurry erosion in the robot polishing of optics by polishing slurry nozzles

Modern optical manufacturing techniques, such as stress disc polishing, bonnet polishing, magnetorheological finishing, and ion beam finishing, suffer from edge effects or low removal efficiency. To solve the above problems, this paper mainly studies dual-axis wheel polishing technology. According to the Preston equation combined with Hertz contact theory and kinematics, a theoretical removal function model of dual-axis wheel polishing is established. Then, the removal function shape and removal efficiency under different revolution-to-rotation speed ratios are simulated. From the simulation results, it can be concluded that the removal function of the dual-axis wheel polishing technology in this paper is Gauss type when the revolution-to-rotation speed ratio is 10:1 or less. With the increase of rotation ratio, the efficiency of the removal function is higher. This paper establishes a theoretical foundation for the design of the dual-axis wheel polishing device.

“…Although some research has been carried out on polishing cutting inserts, no single study exists which provides a batch polishing machine for smoothing ank, nose, and edge simultaneously with nanometer scale surface roughness. Meanwhile, other mainstream polishing methods such as bonnet polishing [37][38], uid jet polishing [39][40] and magnetorheological nishing [41][42] are not suitable for the polishing of cutting inserts due to the high equipment cost and polishing cost. This paper presents a novel method, called 'magnetic eld-assisted batch polishing (MABP)', for automatic batch polishing cutting inserts simultaneously, together with nanometer scale surface nish.…”

To reduce tool wear of inserts in cutting, this study presents an emerging magnetic field-assisted batch polishing (MABP) method for simultaneously polishing multiple ceramics cutting inserts. The wear characteristics are clarified by cutting S136H steel. The surface roughness in regard to mean height (\(Sa\)) at the flank face, edge, and nose has achieved below 2.5 nm, 6.25 nm, and 45.8 nm, respectively after 15 minutes of polishing, and the tool life was extended by 175%. The experimental results indicate that MABP is an effective method for mass polishing the cutting inserts, and the polished surfaces can notably reduce tool wear.

Ceramic cutting inserts are a type of cutting tool commonly used in high-speed metal cutting applications. However, the wear of these inserts caused by friction between the workpiece and cutting inserts limits their overall effectiveness. In order to improve the tool life and reduce wear, this study introduces an emerging method called magnetic field-assisted batch polishing (MABP) for simultaneously polishing multiple ceramic cutting inserts. Several polishing experiments were conducted under different conditions, and the wear characteristics were clarified by cutting S136H steel. The results showed that after 15 min of polishing, the surface roughness at the flank face, edge, and nose of the inserts was reduced to below 2.5 nm, 6.25 nm, and 45.8 nm, respectively. Furthermore, the nose radii of the inserts did not change significantly, and there were no significant changes in the weight percentage of elements before and after polishing. Additionally, the tool life of the batch polished inserts was found to be up to 1.75 times longer than that of unpolished inserts. These findings suggest that the MABP method is an effective way to mass polish ceramic cutting inserts, resulting in significantly reduced tool wear. Furthermore, this novel method offers new possibilities for polishing other tools.
