在产品的最终加工过程中用精磨去除零件中的畸变是一个既费钱又费时的事情。例如 ,仅在 (车辆 )传动技术领域 ,1995年德国用于最后精磨以消除工件的畸变而增加的成本已达 8 5亿欧元。迄今为止 ,行业人士认为在最后的产品加工过程中导致零件产生畸变的主要原因在于淬火过程 ,而今大家普遍认为这个观点不是很对 ,认为淬火过程只是释放了在各个加工环节中积累在工件中的畸变潜能 ,如铸造、车削加工、铣削、淬火、磨削。由不来梅大学创立及DeutscheForschungsgemeinschaft资助的合作研究中心SFB 5 70“畸变工程”的研究方针是从系统导向着手 ,分析零件的畸变。合作研究中心由 12个子项目组成 ,涉及 2 0多位来自材料科学、制造技术、数学及过程控制工程的研究人员。根据系统导向的方法 ,合作研究中心SFB 5 70“畸变工程”认为 ,与优化零件整个生产过程 (工序链 )相比 ,对零件生产过程中的单个过程的优化是第二位的。为了推广系统导向的方法 ,保证SFB 5 70“畸变工程”中集中在不同工序和技术的这 12个子项目间的一个连续、协调的知识和信息交换 ,已成立了一个系统模式工作组。这个工作组的焦点在于详细阐述和进一步发展系统导向的方法以及协调应用于这些子项目中的工序和方法。和其它方法相比较 ,整体方法包?
It is a costly and time-consuming task to fine-remove the distortion in the part during the final machining of the product. For example, only in the field of (vehicle) drive technology, the additional cost of 1995 in Germany for final finishing to eliminate distortion of workpieces has reached 850 million euros. So far, the industry believes that in the final product processing lead to distortion of the parts is the main reason for the quenching process, and now we generally agree that this view is not quite right, that the quenching process is only released in the various parts of the process of accumulation in the workpiece Distortion potential, such as casting, turning, milling, quenching, grinding. Collaborative Research Center funded by the University of Bremen and Deutsche Forschungsgemeinschaft SFB 5 70 The project “Distortion Engineering” is a system-oriented approach to the analysis of part distortions. The collaborative research center comprises 12 subprojects involving more than 20 researchers from materials science, manufacturing technology, math and process control engineering. According to the system-oriented approach, the SFB 5 70 “Distortion Engineering” at the Cooperative Research Center argues that the optimization of a single process in the production of a part is second to none in the entire manufacturing process (process chain). In order to promote a system-oriented approach and to ensure a continuous, coordinated exchange of knowledge and information among the 12 sub-projects of SFB 5 70 “Distortion Engineering” focused on different processes and technologies, a system-wide working group has been established. The focus of this working group is to elaborate and further develop system-oriented approaches and to coordinate the processes and methods applied to these sub-projects. Compared with other methods, the overall method package?
