Wear reduction at double face grinding with planetary kinematics

摘要

To machine high performance materials efficient and process safe, innovative tool concepts are required. Double face grinding with planetary kinematics is a process, which can be used to machine workpieces with high demands on flatness. Especially the kinematic of this process leads to an unequal wear shaping, which has a negative effect on the quality of the workpieces. Fulfilling the sophisticated task of ceramic machining, it is necessary to consider the chip formation and the associated wear of grinding tool based on existing approaches under consideration of the radius dependent speed gradient and significantly increased grinding wheel speeds as well. The research is the basis for the development of a tool, which allows predicting wear on the tool for double face grinding with planetary kinematics. Based on the knowledge about the wear, it is possible to design tools with requirements and customized for special processing task.
