近年来人们在购置特种刀具和大量昂贵的标准刀具时愈来愈多地考虑到经济性计算结果的影响。因此,下面将通过刀具参数和切削条件对经济性计算的基本概念和影响程度加以说明。1、生产成本的计算在一般情况下,生产成本K_F 由工作地点费用求得。前者由计时工资(包括工资——额外费用在内)K_(LH),单件机器时间的成本K_(MH),其他项目所需总成本K_(XH),在刀具耐用度期间的刀具成本K_((?)T),以及单件工时t_e,切削机动
In recent years, people have increasingly considered the impact of economic calculations on the purchase of special tools and a large number of expensive standard tools. Therefore, the basic concept of economy calculation and the degree of influence will be explained by the tool parameters and cutting conditions. 1, the calculation of production costs Under normal circumstances, the cost of production K_F obtained by the cost of the workplace. The former is composed of hourly wage (including salary-extra cost) K_ (LH), cost per piece of machine time K_ (MH), total cost of other items K_ (XH), tool cost during tool life K_ ((?) T), and a single piece of work t_e, cutting maneuvering
