“…This method can polish irregular surface efficiently, but the direct impact of diamond powder during blasting easily causes defects, such as work hardening, superficial embedment of abrasive grains and excessive scratches [5]. Aero Lap is a trial using flexible medium wet soft balls to polish workpiece, in which process the wet soft balls can help to absorb excessive striking energy of the abrasive grains and thus reduce damages [6], but the wet balls may block in the nozzle during the jetting and result in a low efficiency of polishing [7].…”

Surface polishing is an important technique in the precision/ultra-precision process, especially in the optical industry. This paper introduces a new polishing method named Flexible Polishing by Compound Diamond Powder (FPCDP), in which the polishing abrasive grains are made of a kind of compound particles with flexible base and abrasive diamond powder. In FPCDP process, the compound abrasive grains are jetted onto the workpiece surface with an accelerated speed at an incident angle, and the micro irregularities on the workpiece surface are removed during the scratching, rolling and ploughing by the compound abrasive grains. The mechanism of polishing process is analyzed and the machining condition is optimized by experiments, which shows that FPCDP is an efficient method to improve the glass surface roughness.

“…Mechanical polishing processes such as edge honing, aero-lap polishing, and microblasting are widely applied to cutting tools. 13 Owing to the complex geometry of the ball nose end mill, the present polishing processes are time consuming. As the cutting edge of a tool needs to be featured with a residual compressive stress, no previous attempts were made to use any thermally dominated processes for the cutting edge polishing.…”

Electro-polishing was used as an alternative to mechanical polishing for the cutting edge preparation of tungsten carbide (WC) ball nose end mills. High-quality cutting edge surfaces with roughness of magnitude 0.3-0.35 mm was achieved using the electro-polishing process. A direct current of 0.96 A was passed through an electrolytic cell containing the electrolyte sodium hydroxide with a concentration-2.5 mol/dm 3. The ball nose end mill was suspended as the anode and a stainless steel (SS304) as the cathode. The ball nose end mill was electro-polished using the optimized parameters which was obtained through performing the preliminary experiments on tungsten carbide coupons of size D6 Â 20 mm. The effects of electro-polishing on the surface texture of the ball nose end mill were determined using surface texture examinations. Machining tests were conducted on Ti6Al4V alloy to understand the growth of flank wear on the electro-polished ball nose end mills. After every 5 m of cutting distance, flank wear measurements were done for both the regular ball nose end mill and the electro-polished ball nose end mills. The results revealed that the electro-polished ball nose end mill reached a flank wear of 0.15 mm after a cutting distance of 550 m. This was significantly more than the cutting distance of the standard ball nose end mill of magnitude 350 m for the same amount of flank wear. This showed an increase in tool life of over 50%.
