【摘要】 综合了估价法和对比法两种模具报价方法,针对小型冲压模提出了估算和精确计算相结合的报价思路,建立了相应的数学模型。对数学模型估算部分中的基本参数用最小二乘法进行修正,提高了估算精度,并提供了可用于程序设计的数学模型中的拟合曲线解法。更多还原

【Abstract】 By comparing two common mould quoting methods,estimation and comparative method,the mould quoting method which integrates accurate calculation and estimation is chosen.With the example of mini-type punching mould,the mathematics model is established.The basic parameter modified model is established with the method of least square,so as to improve the precision of estimation and the numerical method of curve fitting on the programming is given.更多还原
