Accuracy Measurement and Evaluation of Straight Bevel Gear Manufactured by End Mill Using CNC Milling Machine
Journal of Mechanical Design Transactions of the ASME, 2009Co-Authors: Kazumasa Kawasaki, Kazuyoshi ShinmaAbstract:Straight bevel Gears are usually manufactured with various machines and systems, and the tooth profiles are produced by grinding or machining by means of a tool with many cutting edges. In recent years, the straight bevel Gear has been manufactured by an end mill using a computer numerical control (CNC) milling machine because the use of the auxiliary apparatus, special cutters, and special machine tools is not needed. Using this method, the Gear Manufacturing with high accuracy is an important problem. In this paper, the coordinate measurement of the straight bevel Gear manufactured in this method is performed and the Gear accuracy is evaluated. The tooth profiles of the straight bevel Gear generated by a quasi-complementary crown Gear instead of a conventional complementary crown Gear are introduced. For this study, the tooth profiles of the straight bevel Gear were modeled using a 3D computer-aided design system and the Gear was manufactured by an end mill using a CNC milling machine based on a computeraided Manufacturing process. Afterward, the coordinates of many points on the Gear tooth surfaces were measured at random using a coordinate measuring machine. This coordinate measurement provides the information about the factors related to the Gear accuracy such as pressure angle, tooth angle error, workpiece setting angle, apex to back, and so on. Therefore, the values of the above factors were estimated and were compared with the theoretical ones, respectively. Copyright © 2009 by ASME.

Recent developments in sustainable Manufacturing of Gears: A review
Journal of Cleaner Production, 2016Co-Authors: Kapil Gupta, João Paulo Davim, Ryno Laubscher, N.k. JainAbstract:Environment awareness is of the utmost importance to all socially responsible manufacturers. To be competitive on a global scale Manufacturing needs to be aligned with various strict environmental regulations. The Manufacturing industry at large is striving to improve productivity and product quality while maintaining a clean and sustainable environment. This can only be achieved by adopting sustainable techniques of Manufacturing which include minimizing the number of Manufacturing steps by employing advanced and alternative methods, environment-friendly lubricants and lubrication techniques while machining, reducing wastage, active waste management and minimizing energy consumption etc. Gear Manufacturing industries, the major service providers to all other industrial and Manufacturing segments are also focusing on to implement the techniques targeting overall sustainability. Some of the recent developments to achieve sustainability in Gear Manufacturing can be summarized as: reducing the use of mineral-based cutting fluids by employing alternative lubrication techniques i.e. minimum quantity lubrication (MQL) and dry machining; material saving, waste reduction, minimizing energy consumption and maintaining economic efficiency by reducing the number of Gear Manufacturing stages; eliminating the necessity of finishing processes by utilizing advanced methods such as Gear rolling and wire electric-discharge machining (WEDM) and finally increasing productivity by minimizing tool wear at high Gear cutting speeds through the use of alternative tool materials and coatings. This paper reviews and amasses the current state of technology for sustainable Manufacturing of Gears and also recommends ways to improve the productivity and quality while simultaneously ensuring environmental sustainability.

On Micro-Geometry of Miniature Gears Manufactured by Wire Electrical Discharge Machining
Materials and Manufacturing Processes, 2013Co-Authors: Kapil Gupta, N.k. JainAbstract:This article presents the investigations on micro-geometry of fine pitch miniature spur Gears manufactured by wire electrical discharge machining (WEDM). Effects of voltage, pulse-on time, pulse-off time, wire feed rate and cutting speed on total profile and accumulated pitch errors were studied using one-factor-at-a-time approach. The miniature Gears had a module of 0.7 mm, outside diameter 9.8 mm, face width 4.9 mm, and were made of brass. The best quality manufactured Gear had DIN quality number of 6 and 8, respectively, for pitch and profile with average and maximum surface roughness values of 1 µm and 6.4 µm, respectively, establishing WEDM as a superior process for miniature Gear Manufacturing. It was observed that wire-lag and irregular shaped craters produced by high discharge energy parameters are responsible for micro-geometry errors of miniature Gears manufactured by WEDM. Use of low voltage and pulse-on time, avoiding high pulse-off time, maximum values of wire feed rate and cutting speed are ...

Modern Manufacturing of Miniature Gears
Solid State Phenomena, 2019Co-Authors: Kapil GuptaAbstract:This paper explains and demonstrates how miniature Gears of excellent surface quality can be manufactured by modern machining methods. Necessity of Gear finishing by post processes such as grinding, lapping, honing etc. is the major limitation of all conventional methods of miniature Gear Manufacturing. To overcome this limitation, modern machining methods such as wire-EDM, abrasive waterjet machining, and laser beam machining etc. have been explored. It resulted in significant achievements in geometric accuracy, surface finish, and integrity of miniature Gears. Using modern machining methods, it is possible to manufacture Gears equipped with precision finish (average roughness 1 μm), high geometric accuracy (DIN quality 5), and defect-free tooth surfaces at significantly low cost. This paper aims to facilitate researchers by providing information on important aspects as regards to the Manufacturing of miniature Gears by modern machining methods and hopes research and development in this area to establish the field further.

analysis and optimization of micro geometry of miniature spur Gears manufactured by wire electric discharge machining
Precision Engineering-journal of The International Societies for Precision Engineering and Nanotechnology, 2014Co-Authors: Kapil Gupta, N.k JainAbstract:Abstract This paper reports about the analysis and optimization of micro-geometry parameters (i.e. total profile deviation ‘Fa’ and accumulated pitch deviation ‘Fp’) of the wire electric discharge machined (WEDMed) fine-pitch miniature spur Gears made of brass. Effects of four WEDM process parameters namely voltage, pulse-on time, pulse-off time and wire feed rate on the micro-geometry of the miniature Gears were analyzed by conducting the experiments designed using Box–Behnken approach of response surface methodology (RSM). Analysis of variance study found all four input parameters significant. Larger deviations in profile and pitch were observed with higher values of the voltage and pulse-on time, and with lower values of wire feed rate and pulse-off time. Multi-performance optimization of WEDM parameters was done using the desirability analysis to minimize profile deviation and pitch deviation simultaneously. The values of Fa and Fp of the Gear obtained by the confirmation experiment conducted at the optimized WEDM parameters were as 11.5 μm and 9.1 μm respectively. These values categorize the WEDMed Gear having DIN quality number as 7 and 5 respectively for profile and pitch which are better than those obtained by the conventional miniature Gear Manufacturing processes.
