Abstract
Hybrid process chains lack structured decision-making tools to support advanced manufacturing strategies, consisting of a simulation-enhanced sequencing and planning of additive and subtractive processes. The paper sets out a method aiming at identifying an optimal process window for additive manufacturing, while considering its integration with conventional technologies, starting from part inspection as a built-in functionality, quantifying geometrical and dimensional part deviations, and triggering an effective hybrid process recipe. The method is demonstrated on a hybrid manufacturing scenario, by dynamically sequencing laser deposition (DLM) and subtraction (milling), triggered by intermediate inspection steps to ensure consistent growth of a part.
Highlights
The successful implementation of a newly designed component in the manufacturing chain and the generation of a suitable process plan is a highly complex task, which requires significant human expertise
Novel manufacturing technologies are rapidly emerging and establishing their position in the manufacturing sector. Their emergence is accompanied by the need to create tools and support systems, which will allow for the maximum exploitation of their potential in manufacturing applications, while reducing the necessity for human expertise and increasing the automation levels in the process planning stage [2]
The goal of this paper is to introduce a process planning approach, which, apart from aiding the automation of operation sequencing in a hybrid manufacturing process, will provide a holistic tool for hybrid manufacturing planning
Summary
The successful implementation of a newly designed component in the manufacturing chain and the generation of a suitable process plan is a highly complex task, which requires significant human expertise. Novel manufacturing technologies are rapidly emerging and establishing their position in the manufacturing sector. Their emergence is accompanied by the need to create tools and support systems, which will allow for the maximum exploitation of their potential in manufacturing applications, while reducing the necessity for human expertise and increasing the automation levels in the process planning stage [2]. Direct laser melting (DLM) is gaining interest in the manufacturing value chain as one of the key.
