切削时间的计算,可通过已知的工作台进给速度进行,用毫米/分表示。工作台进给速度F由所用铣刀齿数n、铣刀每分钟转速R、每齿每转进给量f确定。一般计算公式为,F=f·R·n。本文提供一种计算图表,可快速进行计算,只要已知上述四项参数中的E项,即可确定另一项参数。图表中的每一刻度都标有已知参数数字,用一直尺连接刻度,便可找到未知数。例如:已知铣刀齿数n=12、转速R=400转/分、每齿每转进给量f=0.15毫米,查表如下:
The cutting time is calculated by the known table feed rate in mm / min. Table feeding speed F by the number of milling cutter n, mill speed per minute R, feed per tooth per revolution f to determine. The general formula is, F = f · R · n. This article provides a calculation chart that allows for quick calculation as long as the other of the above four parameters are known. Each scale in the chart is marked with a known number of parameters, with a ruler connected to the scale, you can find the unknown. For example: Known number of milling cutter n = 12, speed R = 400 rev / min, feed per tooth per revolution f = 0.15 mm, look-up table is as follows:
