优化的摆铣可提高加工 CFRP 时的工艺效率和加工质量

基本信息

项目摘要

The objective of this project is to optimize the existing wobble milling process to increase process efficiency and improve the machining quality in cooperation with an industrial partner. In addition to wobble milling further insights for tool design for machining fiber reinforced plastics (FRP) will be generated in this project. The subgoals of this project are to reach an increase of process efficiency and a reduction of damage with the optimized wobble milling process when drilling FRP, to develop a simulation program for process design and determination of tool geometry for multiaxial machining processes considering the material setup as well as to create a procedure for industrial process design. The optimized wobble milling should allow significant increase in efficiency in comparison to the present wobble milling caused by the new setup at additionally improved machining quality. The increase of efficiency will be ensured with the reduction from three to two process steps. In this way the process complexity as well as processing time for wobble milling decreases. The primary challenges for process development consist in the design and determination of interactions between the individual geometry parameters of the tool. The geometrical elements need to be balanced in a way that when machining the top layer in the first process step the process force needs to be directed downwards to the inner of the workpiece. In the second process step the process force at the bottom side needs to be directed upwards to the inner of the workpiece. The investigations of different layer structures with continuous fiber reinforcement ensure the spread of effective usability of the developed process. The challenge for the development of the simulation program consists in the description of the process kinematic, the implementation of material parameters and the developed process force models. With this program a new module will be created at which the process design can be adjusted to various requirements. The simulation is necessary for tool and process design and allows a dissemination of the developed processes to the industrial environment. Within the planed project a significant gaining knowledge for machining of FRP can be reached. In addition to the validation of the process an approach for the use of the optimized wobble milling in industrial environment will be developed. Therefore this research project provides a substantial contribution for a sustainable and economic production and offers a direct benefit for technical applications.
该项目的目标是优化现有的摆动铣削工艺,以提高工艺效率,并与工业合作伙伴合作提高加工质量。除了摆动铣削,该项目还将为加工纤维增强塑料(FRP)的刀具设计提供进一步的见解。该项目的子目标是在钻FRP时通过优化的摆动铣削工艺来提高工艺效率和减少损伤,开发用于工艺设计的模拟程序,并考虑材料设置确定多轴加工工艺的刀具几何形状,以及创建用于工业工艺设计的程序。优化的摆动铣削应允许在效率上的显着增加相比,目前的摆动铣削所造成的新的设置在额外提高加工质量。通过将三个工艺步骤减少到两个工艺步骤,将确保效率的提高。通过这种方式,摆动铣削的工艺复杂性和加工时间都降低了。工艺开发的主要挑战在于设计和确定刀具各个几何参数之间的相互作用。几何元件需要以这样的方式平衡,即当在第一工艺步骤中加工顶层时,工艺力需要向下指向工件的内部。在第二工艺步骤中,底侧处的工艺力需要向上指向工件的内部。对连续纤维增强的不同层结构的研究确保了所开发工艺的有效可用性。模拟程序的开发面临的挑战在于过程运动学的描述,材料参数的实施和开发的过程力模型。使用该程序将创建一个新的模块,在该模块中可以根据各种要求调整工艺设计。模拟对于工具和工艺设计是必要的,并且允许将开发的工艺传播到工业环境。在计划的项目中,可以获得大量的FRP加工知识。除了验证工艺外,还将开发在工业环境中使用优化摆动铣削的方法。因此,该研究项目为可持续和经济的生产做出了重大贡献,并为技术应用提供了直接利益。
