零件制造成本估算是工业企业的一项重要任务。价格评估有助于企业在市场中占据成功的竞争力。实际上，模具制造成本估算主要有三种方法：解析法、类比法和参数法，本文提出了一种基于半解析法的模具制造成本估算系统。所开发的系统使用基于类比方法和分析方法的原理的半分析方法。该原理在将待加工的形状分组为复杂的加工特征之前，求助于类比方法来搜索它们之间的类比[1]。对于每个特征参数，系统生成要用作样本的过程，从而生成加工时间的模型。在第二阶段，通过使用分析方法，切削时间由粗加工的金属单元的去除率（cm 3/min）或精加工表面的去除率（cm 2/min）或两种生产方式确定[1]。通过为每种加工类型[2]开发的方程计算切削后返回时间。
Part manufacturing estimation cost is a critical and important task for industrial firms. Price evaluation helps the enterprise occupy a successful competitiveness in the market. In fact there are three main approaches for the manufacturing cost evaluation the analytic approach, the analogic approach and the parametric approach.This paper presents a cost estimation system of manufacturing dies based on a semi-analytic approach. The developed system uses a semi-analytic approach based on the principle of the analogic approach and analytic approach. This principle has recourse to the analogic approach to search for analogies between the shapes to be machined before grouping them into complex machining features [1]. For each feature parameter the system generates a process to be used as a sample and consequently a model of machining time. In a second stage and by using the analytic approach, the cutting time is determined either by removal rates of metal units for rough operation (cm3/min) or from the finishing operation surface (cm2/min) or by both production ways [1]. The after cutting return time is calculated through the equations developed for each machining type [2].
