TL;DR: In this article, the authors describe the operation of a gear-like dies in the form of hypoid gears and pinions, which are run in mesh, without substantial relative movement other than rotation, with a honing or polishing tool.
Abstract: Operating gears or gear-like dies in the form of hypoid gears and pinions are finished by running them in mesh, preferably without substantial relative movement other than rotation, with a honing or polishing tool in the form of a mating hypoid pinion or gear, respectively.

TL;DR: In this paper, a simple testing method for mechanical properties of materials in high-pressure hydrogen environments has been developed, which does not require any high pressure vessel but the high pressure hydrogen environment is produced inside the hole in the specimen.
Abstract: A simple testing method for mechanical properties of materials in high-pressure hydrogen environments has been developed. This method does not require any high-pressure vessel but the high-pressure hydrogen environment is produced inside the hole in the specimen. The specimen temperature is easily controlled by outside environment. The effects of hydrogen environment embrittlement (HEE) for SUS304 and 304L at 298, 190, and 77 K were evaluated by the ratio of reduction of area obtained in tensile tests in hydrogen to that obtained in helium. The results of the evaluation by this testing method agreed fairly well with the results by the usual method using a high pressure vessel. The hole in the specimen was machined by electric discharge, wire-cut, and honing. The influence of surface roughness on HEE was compared among these processes and the wire-cut machining was found to be enough for this new method. Changes of HEE with temperature and fracture surface by hydrogen proved the usefulness of this new simple method.

TL;DR: In this paper, the authors describe an ELID tool with a fixed guide and a fixed radius R from the rotation axis to its outer peripheral surface, which is capable of being subjected to a negative voltage.
Abstract: An ELID honing device includes a honing tool 10 positioned above a workpiece 1 having a hollow cylindrical inner surface, and vertically movable and rotationally drivable about a vertical rotation axis while being rockably suspended from an upper end, and a honing guide 20 positioned in proximity to an upper portion of the workpiece to guide the honing tool to the hollow cylindrical inner surface. The honing tool 10 has a fixed guide 12 having a predetermined radius R from the rotation axis to its outer peripheral surface, and honing stones 14a and 14b having outer peripheral surfaces movable in parallel from a diameter-increased position outside the radius R to a diameter-reduced position inside the radius R and capable of being electrolytically dressed. Further, the honing guide 20 has a hollow cylindrical ELID electrode 22 having an inner surface 22a for guiding an outer peripheral surface of the fixed guide of the honing tool and capable of being subjected to a negative voltage.

TL;DR: In this article, a new approach using a pulse YAG laser with rational power density and pulse width to texture desired discrete distribution morphology on the cylinder wall was developed, which reduced the coefficient of friction and wear rate of laser texturing cylinders.
Abstract: Purpose - The purpose of this study was to develop a new approach using a pulse YAG laser with rational power density and pulse width to texture desired discrete distribution morphology on the cylinder wall. Design/methodology/approach - Variational rules of the effects of these three parameters were found by calculating the oil film on the cylinder/piston ring system. The experiment results were compared between laser texturing cylinders and conventional honing cylinders. Findings - It was found that the coefficient of friction and wear rate of laser texturing cylinders were reduced by 50 and 85.7 per cent, respectively, and the piston ring wear rate was decreased by 50 per cent under full lubrication condition. Under starved lubrication condition, the cylinder liner wear was reduced by 34.3 per cent. Originality/value - The effectiveness of which was determined by three control parameters: depth-to-diameter ratio, area density and distribution angle of the dimples.

TL;DR: In this paper, the rotary magnetorheological honing (R-MRH) process was used for internal surface finishing of cast-iron cylindrical workpieces.
Abstract: The cylindrical mold is an essential part used in industries for the manufacturing of various cylindrical products such as beverages canes, domestics appliances, glass beakers, and polyvinyl chloride pipes. These products require features in its surfaces such as defect-free surfaces with high-quality, stable dimensions, the high extent of cylindricity, and functional transparency in glass material products. To acquire such features in the cylindrical products, the rotary magnetorheological honing (R-MRH) process is developed. In this work, the response surface methodology technique is employed for optimizing the process parameters for internal surface finishing of the cast-iron (CI) cylindrical workpieces. With the optimized process parameters, the experiments are performed to find out the effectiveness of the present finishing process for CI cylindrical molds. On the final MR-finished surface after 40 min of finishing, the roughness parameters (Ra, Rz, and Rq) get reduced to 0.05 µm, 0.4 µm, and 0.07 µm from the respective initial values of 0.420 µm, 2.4 µm, and 0.52 µm. The waviness parameters (Wa, Wz, and Wq) achieved on the final finished surface are 0.04 µm, 0.20 µm, and 0.06 µm from the initial values of 0.17 µm, 0.90 µm, and 0.22 µm, respectively. Also, the circularity (C) on the MR-finished cylindrical surface is improved to 0.0437 from the initial circularity value of 0.1207. The significant changes in Ra, Wa, and C values as well as visuals of scanning electron microscopy images reveal a better sense of functionality improvement of the cast-iron cylindrical molds.
