  • There are a lot of questions about HSM today and many different, more or less complicated, definitions can be seen frequently. Here the matter will be discussed in an easy fashion and from a practical point of view. This article is the first in a series of articles about die and moldmaking from Sandvik Coromant. In a following article HSM will be further discussed. Historical background The term High Speed Machining (HSM) commonly refers to end milling at high rotational speeds and high surface feeds.

  • (BQ) The paper describes the application of the fuzzy logic analysis coupled with Taguchi methods to optimise the precision and accuracy of the high-speed electrical discharge machining (EDM) process. A fuzzy logic system is used to investigate relationships between the machining precision and accuracy for determining the efficiency of each parameter design of the Taguchi dynamic experiments.

  • This paper describes a new hardware algorithm for morpheme extraction and its implementation on a specific machine (MEX-I), as the first step toward achieving natural language parsing accelerators. It also shows the machine's performance, 100-1,000 times faster than a personal computer. This machine can extract morphemes from 10,000 character Japanese text by searching an 80,000 morpheme dictionary in I second. It can treat multiple text streams, which are composed of character candidates, as well as one text stream.

  • (BQ) The study used Taguchi dynamic approach coupled with a proposed ideal function model to optimize a high-speed EDM process for high geometrical machining precision and accuracy. The designed tool electrode including two basic geometries of square and circle as the distinct characteristics of workpiece is employed to help develop a versatile process for wider industrial applications. To enhance the speed and stability of EDM process, large discharge current is applied and aluminum (Al) powder added into the working fluid throughout the experiments.

  • Keywords: Screw Drive, Dynamic Model, Vibration Modes, Ritz Series. Abstract. The ball screw drives are among the most commonly mechanisms used to provide motion in high speed machine tools. The most important factor that affects high speed positioning accuracy is the closed loop bandwidth, which in turn is affected by the structural vibration modes.

  • Flat belts drives can be used for large amount of power transmission and there is no upper limit of distance between the two pulleys. Belt conveyer system is one such example. These drives are efficient at high speeds and they offer quite running. A typical flat belt drive with idler pulley is shown in Fig. 13.2.1. Idler pulleys are used to guide a flat belt in various manners, but do not contribute to power transmission. A view of the flat belt cross section is also shown in the figure.

  • SUMMARY This chapter addresses the design of cam systems in which flexibility is not a consideration. Flexible, high-speed cam systems are too involved for handbook presentation. Therefore only two generic families of motion, trigonometric and polynomial, are discussed. This covers most of the practical problems. The rules concerning the reciprocating motion of a follower can be adapted to angular motion as well as to three-dimensional cams. Some material concerns circular-arc cams, which are still used in some fine mechanisms....

  • The machining of complex sculptured surfaces is an important technological topic in modern manufacturing, namely in the molds and dies sector. Today, this sector, with great importance to automotive, aircraft and others advanced industries, is placed in all industrialized or emerging countries. In the recent past, the traditional technology employed in molds and dies manufacture was a combination of con- ventional milling and electro-discharge machining (EDM) or electrochemical machining (ECM).

  • The years 1945–55 saw the emergence of a radically new kind of device: the high-speed stored-program digital computer. Secret wartime projects in areas such as code-breaking, radar and ballistics had produced a wealth of ideas and technologies that kick-started this first decade of the Information Age. The brilliant mathematician and code-breaker Alan Turing was just one of several British pioneers whose prototype machines led the way. Turning theory into practice proved tricky, but by 1948 five UK research groups had begun to build practical stored-program computers.
