Abstract

The efficiency of a production chain that includes different processes is strongly influenced by the quality of the parts delivered from one production process to the next. In the present case, the machining costs for forged parts in multispindle chucking automatics are strongly influenced by their dimensional variations. Quality assurance of forged parts is challenging because of their complex shape. Acceptance criteria for dimensional variations that can be accepted by production departments succeeding forming are difficult to describe and to measure. Consequently, there exists only little knowledge about process capabilities for forged parts in general. Often, machining and assembly can not even give sufficient information about their requirements and therefore experience disturbance of their production. A discussion and case study about this will be presented in this paper.
