Defined cutting edge preparation by 3D form grinding

切削刃的几何形状对确定切削刃几何形状的切削过程中切屑的去除具有很大的优化潜力。它对切削加工的经济性、生产率和工艺可靠性有重大影响。通过三维成形磨削工艺制造复杂形状和精确定义的切削刃迄今为止只是实施不足。考虑到灵活的切削刃几何形状和高再现性，开发用于切削刃制造的三维成形磨削工艺是非常重要的。为了实现可靠和经济的刃口制造工艺，需要对形状磨削的主动机构进行知识汇编。因此，所要求的研究项目的主要目标是开发一种3D形状磨削工艺，用于可转位刀片上复杂切削刃的定义和可靠制造，其中将分析不同切削刃几何形状和切削材料的适用性。进一步分析了影响因素对工作结果的影响，以及对磨具工艺参数和磨损参数的影响。为了对三维成形磨削过程进行工艺分析，选择了适合在几何确定的切削刃上制造特定几何形状的金刚石磨削点。这种加工工艺的选择也证明了几何形状的高灵活性和高再现性。

The geometry of cutting edges has a high potential for the optimization of chip removal in cutting with geometrically determined cutting edges. It has a significant impact on the economy, productivity and process reliability of cutting processes. The manufacturing of complex shaped and exactly defined cutting edges by 3D form grinding processes have been implemented only deficient so far. With regard to a flexible cutting edge geometry and a high reproducibility the development of a 3D form grinding process for cutting edge manufacturing is very important. Knowledge about the active mechanisms in form grinding needs to be compiled in order to realize a reliable and economical manufacturing process of cutting edges. Hence the main goal of the requested research project is the development of a 3D form grinding process for the defined and reliable manufacturing of complex cutting edges on indexable inserts, in which the applicability for different cutting edge geometries and cutting materials will be analyzed. Furthermore the impact of the influencing factors on the work result and the process and wear parameters of the grinding tools will be performed. For the technological analysis of the 3D form grinding process, diamond grinding points were chosen which are well suited for a manufacturing of specific defined geometries on geometrically determined cutting edges. The choice of this machining procedure is also justified by a high flexibility for geometries and a high reproducibility.
