In order to improve surface polishing quality and efficiency for hard and brittle components, a novel nozzle with specifically designed shroud was proposed for an abrasive jet polishing process. The removal mechanism of the abrasive jet under such a nozzle was investigated by simulating the jet flow in the interaction area of the nozzle shroud and workpiece. The simulation results show that the speed of the abrasive jet increases greatly by the shroud and the direction of the jet is aligned near parallel to the workpiece surface to minimize impact damage to workpiece surface. The constrained abrasive jet polishing (CAJP) experiments were conducted on the quartz glass component, a typical hard and brittle material, showing that the material removal mainly relied on the shearing and scratching of the workpiece surface rather than the mechanical shock impacts, which is consistent with the simulation findings.

Correction of remounting errors by masking reference points in small footprint polishing process

et al. 2013

The remounting accuracy of optical components between measurement and polishing affects the polishing results, especially for small polishing footprint processes such as magnetorheological jet polishing (MJP). In this paper, two important remounting errors (translation and rotation errors) are discussed, and a masking method is proposed to correct these errors. A mathematical model that describes the relationship between remounting errors and reference points is constructed. A mask is created to provide reference points on a sample because such points are important for identifying remounting errors. The remounting errors are then used as bases in correcting the parameters used for actual polishing. Experiments are conducted on a K9 optical sample to validate the proposed approach. After the reference points are obtained by measuring the mask on the sample, the remounting errors are derived. The translation errors are 5.61 mm in the X direction and 6.08 mm in the Y direction; the rotation error is 4.1°. Deviations from the desired positions are eliminated and the desired surface smoothness is obtained after parameter correction. Results indicate that the proposed method is suitable for high-precision polishing.
