快速计算图具有使用方便、不易出错等优点,其“数”与“形”相结合的特点还使人们易于了解参数变化对结果的影响。所以,在电子计算器十分普及的今天,快速计算图仍不失为工程技术人员的好助手。近年来,机械设计方面的计算图集陆续出版了多种,而机械制造工艺方面的计算图集目前尚付阙如。本刊征约并发表此文,目的不仅在于推荐几幅计算图,而是希望大力推广计算图在机械制造中的应用。应我们要求,全国图算学培训中心可免费为本刊读者绘制机械制造工艺计算图(需提供简要说明、计算公式、参数范围等)。另外,该中心将于今年8月份在青岛举办第五期计算图设计与绘制培训班。需参加者请直接去函青岛市四流南路74号该中心联系(详见本期第5期第48页报道)。
Fast calculation is easy to use, easy to make mistakes, etc. The combination of “number” and “shape” also makes it easy for people to understand the effect of parameter changes on the result. Therefore, in today’s very popular electronic calculators, rapid calculation of the figure is still a good assistant engineering and technical personnel. In recent years, a large number of computer graphics atlas have been published one after another, while atlas of mechanical manufacturing processes has yet to be paid. This journal requisition and published this article, the purpose is not only to recommend a few figures, but rather to promote the application of computational drawings in machinery manufacturing. At our request, the national figure training center can draw the mechanical manufacturing process calculation chart for our readers for free (provide a brief description, calculation formula, parameter range, etc.). In addition, the center will hold the fifth computing design and drawing training course in Qingdao in August this year. For participants, please write directly to the center of No. 74 SiLiu South Road, Qingdao (Please refer to the report of No. 5 of this issue on page 48 for details).
