Abstract

Method to define the batchsize and composition of processes in surface treatment V. Osthus, C. Berger & B. Kaiser Institute of Materials Technology, Darmstadt University of Technology, Germany Abstract Manufacturing methods llke turning or milling, whch treat the workpiece individually or in defined numbers, generally allow an accurate allocation of the environmental impact resulting from the process. Due to the changing batch sizes of the normally used batch process in surface treatment, such allocation is only possible after the actual treatment and lacks the required precision. For financial accounting purposes ths situation is unsatisfactory, because important cost factors like energy consumption, fuel costs, costs of sewage water, disposal of wastes and secondary treatment of emissions are among the impacts resulting from the process. If different workpieces are treated within one batch, it is almost impossible to allocate which resulting impacts depend on the single workpiece. The type a
