论文部分内容阅读
自从本刊一九七五年第二期发表关于交流组合机床主轴箱传动轴坐标计算方面的经验以来,得到了广大读者的热情支持,许多读者来稿,介绍各种计算方法及其在实际工作中应用这些方法的体会。如上海机电设计院欧式武同志来稿介绍应用电子计算机进行坐标运算的通用程序及使用方法;甘肃工业大学数学教研室古以熹同志介绍在没有计算机的条件下,采用对数计算法;安徽巢湖油泵油嘴厂技术科田岩骞同志介绍应用多位三角函数表的计算方法,等等。总之,由于使用的计算工具不同,主轴箱传动轴坐标计算的方法也随之变化。计算的效果,与采用的计算工具的先进性有直接关系。为了使来稿尽快与读者见面,本刊请佟仆玮、曹明霖等同志协助验证后选择发表两篇,以供读者参考,同时,也作为这次交流的小结。
Since our publication in the second issue of 1975, we have received enthusiastic support from readers, many readers have contributed to the presentation of various calculation methods and their practical work Experience with these methods. Such as Shanghai Mechanical and Electrical Design Institute of European-style comrades to submit the application of computer coordinates of the general procedures and methods of use; Gansu Polytechnic University Department of Mathematics Gu Yixi comrades in the absence of computer conditions, the use of logarithmic calculation method; Anhui Chaohu pump nozzle Plant Technology Mr. Yan Tian Ke Qian introduced the use of multiple trigonometry function of the table, and so on. In short, due to the different calculation tools used, the method of calculating the drive shaft coordinate of the spindle box also changes. The calculated result is directly related to the advanced nature of the computational tools used. In order to make contributions as soon as possible to meet with readers, this magazine please Tong Tongwei, Cao Minglin and other comrades to help verify the choice published two articles, for readers reference, but also as a summary of this exchange.
