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.

在先前的项目"几何定义切削刃加工的刀具磨损模拟“中，开发了一种用于预测硬车削中未涂覆cBN刀片刀具磨损的模拟工具。通过与应用合作伙伴肯纳金属公司和奇石乐汽车公司的密切合作，特殊案例的知识和方法将被转移到更广泛的工业应用中。为了实现有用的实际应用，必须加强刀具磨损模拟的方法。由于涂层刀具的重要性，该提案的主要目标是将模拟能力扩展到刀具涂层和基体的组合磨损的模拟。在这方面，需要进一步开发、校准程序和软件实施。此外，模拟方法应针对更广泛的刀具和工件组合进行测试和验证。同时，这些改进必须在一个用户友好的软件工具中实现。最后，该工具应能有效模拟涂层和未涂层工具的工具磨损。因此，基于对话框的应用程序将包含用于若干用例的校准数据和模型以及工具磨损助手，以便支持用户校准附加工具和工件组合。
