现今,可转位的车刀刀片,每个切削刃的实际寿命,因切削条件不同,可在10分钟到4小时范围内选用。那么,可转位刀片每一切削刃的经济寿命应该是多少呢?下面介绍刀具经济寿命的计算方法。大家知道,车床的生产费用是由固定费用、加工费用(即每小时的价格)和工装费用(包括刀体的折旧与刀片的损耗)三项费用构成。图1表示这三项费用的单件费(C)(即每件产品的费用)如何随着切削速度的变化而变化
Today, the indexable turning tool inserts, the actual life of each cutting edge, due to different cutting conditions, can be selected within 10 minutes to 4 hours. So, the economic life of each insert edge indexable blade should be how much? Here’s how to calculate the economic life of the tool. As we all know, lathe production costs by the fixed costs, processing costs (ie, the price per hour) and tooling costs (including the body of the depreciation and blade loss) constitute three costs. Figure 1 shows how the unit fee (C) for these three expenses (ie, the cost of each product) varies with the cutting speed
