用电动计算机或小型台式电子计算机计算主轴箱轴孔坐标时,经常遇到开平方根的运算,而在上述二种计算机上没有开方键钮,使得运算麻烦。本文在考虑了充分利用上述二种计算机能迅速完成四则运算的特点之后,提出了一种平方根的逼近求法,供使用电动计算机和小型电子计算机计算轴孔坐标时采用。图1幅。馆藏号：
Calculating the coordinates of the spindle hole of the spindle box by using an electric computer or a small desktop computer often encounters the operation of the square root of the square root, and there is no opening key on the two kinds of computers, which makes the operation troublesome. In this paper, after taking full advantage of the fact that the above two kinds of computers can make full use of the four arithmetic operations quickly, a square root approximation method is proposed for calculating the coordinate of the axial hole using the electric computer and the small electronic computer.
