Development of a technology orientated programming system for industrial robots
The disassembly of used goods is characterized by strongly varying quantities and a wide range of different kinds and states of products. Furthermore, the requirements of a disassembly system are determined by the disassembly object, by the process as well as by the disassembly system itself. As a result of the high labor costs in industrial countries and the huge amount of used goods, an automated disassembly is favored for the industrial disassembly. New methods for the programming of industrial robots have to be developed because the costs for a programming of small lot sizes are a key factor of the economic efficiency of small and medium sized enterprises (SME). In this paper an off-line programming environment for programming of industrial robots in the field of automated disassembly is presented. The exemplary implementation is realized at a pilot disassembly system, which was built up at the Institut für Werkzeugmaschinen und Fabrikbetrieb (IWF) of the Technische Universität Berlin.
Efficient utilization of production resources in the use phase of multi-technology machine tools
This paper demonstrates an approach to increase operation efficiency of multi-technology machine tools (MTMTs). After discussing the advantages and disadvantages of MTMT designs in general the necessity of simultaneous processing, in order to be competitive in terms of machine hour rates, is derived. Based on the MTMT being built in the Cluster of Excellence at RWTH University the consequences of multiple workspaces for the efficient use of production resources and their influences on overall production times are discussed. Mechanical and thermal effects between the workspaces as well as the complexity of programming multiple processes are discussed with respect to different products and their process chains.
