  • Machining of Spur Gears Using a Special Milling Cutter
    ISSN 1330-3651 (Print), ISSN 1848-6339 (Online) https://doi.org/10.17559/TV-20171120121636 Original scientific paper Machining of Spur Gears Using a Special Milling Cutter Piotr BORAL, Antun STOIĆ, Milan KLJAJIN Abstract: Spur gears have a wide application in the machine-building industry. Machining process primarily selected for these gears is hobbing method with modular hobs, or with Fellows cutters. Other methods which can be applied are profiling using the pull broaches, while the finishing can be done by gear shaving or grinding by the Maag, Niles or Reishauer methods. Moreover, in small (or unit) production, they may be formed using disc- or finger-type modular cutters. The article presents a method for cutting spur gears using a disc-type mill with a variable cutting plate profile. The influence of the number of blades of the presented milling cutter on the accuracy of the worked tooth profile was investigated. Keywords: disc-type milling cutter; gear machining; surface roughness 1 INTRODUCTION In numerous scientific research centres and manufacturing companies, gear analysis software is being The involute profile in spur gears is commonly used built to assist the design of the geometry and technology and practically adopted by all standards worldwide. The of toothed gears [14-17]. durability and good operating conditions of the toothed gears are largely influenced by the manufacturing accuracy and the structure and roughness of the cooperating surfaces [1-3]. These gears are manufactured using many profiling and hobbing methods [4-7]. They are machined chiefly by the hobbing method with modular hobs or Fellows cutters, or by gear shaving by the MAAG or Sunderland method – Fig.

It includes metal cutting, pressing, and various work holding devices. Metal cutting is the operation in which thin layer of metal is removed by wedge shaped tool. Metal cutting is commonly associated with industries like automotive, aerospace, home appliance, etc. The machining of metal and alloys play a crucial role in the range of manufacturing activities including ultra precision machining of extremely delicate components. Objectives After studying this unit, you should be able to • understand the basics of tool engineering, • classify the tooling and machine tools, and • recognise various types of operations performed on different machines. 1.2 BASICS OF TOOL ENGINEERING Machine tools are very important for any industrialised country because they hold a key position in the technology chain. Machine tools are needed to build the machines and parts with which capital goods and consumer goods of all kinds are manufactured, from cars to airplanes, from glasses to ball point pen. If the creative tool engineers and qualified skilled workers are constantly producing faster, better and more intelligent machine tools for the market, they are helping many industries. This means innovation in machine tool industry have a far-reaching and multiplicative impact.

  • Fabrication of Directly Designed Gears with Symmetric and Asymmetric Teeth Alexander L
    technical Fabrication of Directly Designed Gears with Symmetric and Asymmetric Teeth Alexander L. Kapelevich and Yuriy V. Shekhtman Introduction For Related Articles Search When compared with the traditional gear design approach — based on pre-selected, typically standard generating asymmetric rack parameters — the alternative Direct Gear Design (Ref.1) at www.geartechnology.com method provides certain advantages for custom, high-perfor- mance gear drives. Among them are increased load capacity; efficiency; length-of-service; reduced size and weight; noise/ vibrations; and cost. However, the manufacture of such non- standard gears requires custom tooling and certain alterations of known gear fabrication processes. This paper presents specifics of application main methods of gear fabrication, i.e. — form and generating machining (cutting and grinding); gear forming injection molding technology; net forging; powder metal (PM) processing; die casting; and wire EDM gear prototyping. It also describes tooling profile defini- tion, dependent upon the selected gear fabrication method. It presents the Genetic Molding Solution technique for compensa- tion of differential warpage and shrinkage for plastic injection molding tooling — that enables enhancement of gear accuracy and shortens the process development cycle.
