Modular Machine Tool and Process Simulator for Precision Machining

高价值制造的部件至少有25%的加工时间来自机械加工。数控机床被编程为生产几何形状和表面光洁度，加工系统中的误差来源影响成本，质量和交货。这些源分为由机床系统条件引起的源和由工件行为引起的源。该联盟由机器制造商、解决方案提供商、学术机构和最终用户组成，将合作开发一种预测软件工具，该工具独特地集成了机器和加工模型，以提供部件几何形状和表面光洁度的预测和可视化。机器用户将能够模拟在切削周期中机器对零件精度，工作保持和零件灵活性的影响，并相应地设计零件程序，从而减少原型制作和生产停机时间。机器制造商将使用该工具来改进新产品开发的设计和效率。模块化解决方案是控制加工过程精度的全面模型的垫脚石。

At least 25% of the process time for high value manufactured components arises from machining. CNC machine tools are programmed to produce geometry to a nominal form and surface finish, sources of error in the machining system impact on the cost, quality and delivery. These sources are split into those induced by the condition of the machine tool system and those induced by the behaviour of the work piece. The consortium, comprising machine builders, solution providers, academic institutes and end users, will collaborate to produce a predictive software tool that uniquely integrates both machine and machining models to provide prediction and visualisation of component geometry and surface finish. Machine users will be able to model the effects on part accuracy of machine, work holding, and part flexibilities during a cutting cycle, and design their part programs accordingly, thereby reducing prototyping and production downtime. Machine builders will use the tool to improve the design and efficiency of new product development. The modular solution is a stepping-stone to an all-encompassing model for controlling the accuracy of the machining process.
