Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.

This paper investigates optimization problem of the cutting parameters in high-speed milling on NAK80 mold steel. An experiment based on the technology of Taguchi is performed. The objective is to establish a correlation among spindle speed, feed per tooth and depth of cut to the three directions of cutting force in the milling process. In this study, the optimum cutting parameters are obtained by the grey relational analysis. Moreover, the principal component analysis is applied to evaluate the weights so that their relative significance can be described properly and objectively. The results of experiments show that grey relational analysis coupled with principal component analysis can effectively acquire the optimal combination of cutting parameters and the proposed approach can be a useful tool to reduce the cutting force.

国际贸易结算是银行业中一种必不可少的业务,占据着重要的地位,而且随着电子商务的发展,其重要性也越来越突出。但是,这一业务的计算机化相当困难。主要原因是:操作流程复杂;组合变化太多,对灵活性有很高要求;涉及面相当广,几乎涉及银行的每一个业务品种,是一个压缩版的银行系统。因此,开发这样的系统必须采用先进的而且较为合适的方法和技术。文章提出了以构建半成品构件系统为总体思想的开发方法;在设计和实现上,提出了以数据总线为统一接口,以菜单/功能图标为总控主体框架,以基本业务操作为基本组件,并能把基本组件包装裁剪成可在主体框架控制下运行的功能构件,这样构建的系统可按实际需要进行组装、剪裁、参数设定、重新包装或经少量改写而形成一个实际可运行的系统。并提供了与银行总系统集成的灵活接口,具备了向网上银行和分布系统发展的良好基础。
