A slide cover, a core component in the field of machine tool, is substantially affected by dust contaminant, machined chip, and etc. This study developed test equipment for the life test of the slide cover and conducted a preliminary test to investigate the failure mode and mechanism. Thus the life test protocol was established with reflecting the environmental data obtained from the machining software used in the field, and finally some test result for sliding seal degradation was provided.

Eco-robot for collecting recycling products is the machine which collects non-industrial wastes such as cans, PET bottles and etc. to reuse them as recycling resources. This eco-robot is operated in the condition that it should compress and hold various products without knowing their geometric shapes and material properties. For this reason reliability problems like malfunction or failure. comes to emerge, but the reliability test conditions to assess its performance and durability have not been founded yet. Therefore in this research failure mechanism of the eco-robot was analyzed and life test equipment which can reproduce actual usage conditions was developed. The compression levels in the life test were determined by measuring the crushing force acting on test products and . Furthermore the test specimens which have equivalent shape and material properties with those of cans and PET bottles were proposed by simulating the deformation characteristics so that the actual compression conditions were set up in the test.
