二、刀具耐磨时间计算公式之 使用说明 利用公式13可以求出正常负荷机床上刀具的计算耐磨时间。 为了化简计算过程,假定一定工段或整个车间所有的机床实际利用率相等(负荷一样)。 关于额定机床上刀具计算耐磨时间的说明前面已经说过。 设将公式 13写成下式:机床每工作一分钟有 Second, the cutter wear time formula for the use of the use of Equation 13 can be calculated out of the normal load on the machine tool wear time. In order to simplify the calculation process, it is assumed that the actual utilization rate of all the machine tools in a certain section or the entire workshop is the same (the same load). As for the calculation of the wear-resistant time of the tool on the rated machine tool, as mentioned earlier. Let equation 13 be written as follows: Machine every minute work there
