Life Cycle of Multi Technology Machine Tools – Modularization and Integral Design

AbstractFor reasons of high flexibility but still maximum productivity, machine tools integrating various production technologies have recently received particular attention. Combining and integrating multiple manufacturing techniques into one single system in early stages of the product emergence process is challenging. To keep the effort for implementation to a minimum, an initiation already in the concept phase is being actively pursued. Design guidelines are currently investigated based on the examination of different technology combinations.This approach focuses on systematic conceptual design for such hybrid machine technologies. Product architectures are used to describe the modularity and create a specific delimitation for standardization. Reference product architectures for Multi Technology Machine Tools (MTMT) carry high potential for saving expenses in product development. The main emphasis is on technology and system integration. A technological similarity assessment of the single processes involved forms the basis of this approach to assure potential for synergies. Monetary aspects in early stages of product development are considered. Based on the analysis a generic system model is connected with general product architectures for MTMT.The method introduced is validated by a Multi-Technology Machining Centre with two simultaneously usable workspaces integrating a milling spindle and two laser processing units. The research undertaken is part of the Cluster of Excellence “Integrative Production Technology for High-Wage Countries” and has been funded by German Research Foundation (DFG)
