Knowledge transfer for the development and optimization of bonded, vibration-damping joints for single-lip drills, extended by aspects of practicality with regard to production and use of tools

粘结是将切削材料应用于基本刀具主体的替代方法与钎焊相比，粘结所需的时间更长。只有当相应连接的工具具有附加功能时，这才是合理的。使用粘接接头，可以根据特定的振动阻尼特性或过载离合器来设计它们，以避免过高的钻削扭矩导致刀具断裂。因此，该研究项目计划的工作是关于粘接接头的设计和性能的研究。以下项目将与项目合作伙伴Guehring KG密切合作：确定适用于单边深孔钻削操作中使用的工具中的阻尼柄-套筒连接的粘合剂系统。设计、开发和制造一种在室温和烘箱温度下连接轴套的装置，同时保持所需的精度要求。胶接工具位置误差量化量测方法之发展。在粘合系统和接头尺寸方面优化连接过程。基于实验和模拟的采集和评估焊接工具与钎焊参考工具的静态和动态行为。机械加工中可用性的调查与评价。评估粘接接头对冷却润滑剂的耐受性，并调查其在涂层工厂中的适用性。该研究项目的目的是深入了解合适的粘合剂系统以及接头的几何设计，以生产具有足够强度的原型阻尼工具样品。应在常规机加工操作的要求下，与铜焊参考工具进行比较，证明粘结工具的操作能力。

Bonding is an alternative approach to apply cutting materials to basic tool bodies Compared to brazing, the time required for bonding is higher. This can only be justified if the correspondingly joined tools have additional functionalities. Using bonded joints, it is possible to design them regarding to specified vibration damping properties or as overload clutch to avoid tool breakage depending on too high drilling torques. The work planned in the research project is therefore concerned with studies on the design and capabilities of bonded joints.The following items will be worked out in close cooperation with the project partner Guehring KG: Identification of adhesive systems suitable for damping shank-sleeve connections in tools used within single-edge deep hole drilling operations. Conception, development and construction of a device for joining shaft-sleeve connections at room and oven temperature while maintaining the required accuracy requirements. Development of a measuring method for the quantification of position errors on tools with bonded joint. Optimization of the joining process with regard to the adhesive system and the dimensioning of the joint. Experimental and simulation-based acquisition and evaluation of the static and dynamic behavior of bonded tools compared to brazed reference tools. Investigation and evaluation of the usability in machining. Assessment of the resistance of the bonded joint against cooling lubricants and investigations into the applicability in coating plants.The aim of the research project is to gain insights into suitable adhesive systems as well as the geometrical design of the joint to produce prototypical damped tool samples with sufficient strength. The bonded tools operational capability shall be demonstrated under the requirements of customary machining operations in comparison to brazed reference tools.
