项目摘要

Within the prior project 'Simulation of tool wear for the machining with geometrically defined cutting edge' a simulation tool for the prediction of tool wear of uncoated cBN inserts in hard turning has been developed. The knowledge and methods of the special case shall be transferred to a broader range of industrial applications in the following, which will be arranged by a close cooperation with the application partners Kennametal and Kistler Automotive.For a useful practical application, the methodology of the tool wear simulation has to be enhanced. Due to the importance of coated tools, a main objective of the proposal is to extend the simulation capabilities to the simulation of the combined wear of the tool's coating and substrate. Within this aspect, further development, calibration procedures and software implementations are necessary. In addition, the simulation methodology shall be tested and validated for a broader spectrum of tool and workpiece combinations. Simultaneously the improvements have to be implemented into a user-friendly software tool. Finally, this tool shall be able to simulate tool wear of coated and uncoated tools effectively. Therefore, the dialog based application will contain calibration data and models for several use cases and a tool wear assistant in order to support the user to calibrate additional tool and workpiece combinations.

在之前的项目“模拟几何定义切削刃加工的刀具磨损”中，开发了一种模拟工具，用于预测硬车削中无涂层立方氮化硼刀片的刀具磨损。特殊案例的知识和方法将在下文中转移到更广泛的工业应用中，这将通过与应用合作伙伴肯纳金属和奇石乐汽车的密切合作进行安排。为了获得有用的实际应用，该工具的方法论磨损模拟必须得到加强。由于涂层刀具的重要性，该提案的一个主要目标是将模拟功能扩展到刀具涂层和基体的组合磨损的模拟。在这方面，进一步的开发、校准程序和软件实施是必要的。此外，模拟方法应针对更广泛的工具和工件组合进行测试和验证。同时，这些改进必须落实到用户友好的软件工具中。最后，该工具应能够有效地模拟涂层和未涂层刀具的磨损。因此，基于对话框的应用程序将包含多个用例的校准数据和模型以及工具磨损助手，以支持用户校准其他工具和工件组合。
