Abstract: It is important for the CNC machining process of the typical sliding block parts with special shape in automobile mold. The mold structure analysis is developed, and the process schemes and cutting parameters of the mold machine are optimized during producing mold based on the mold structure analysis. The present analysis can solve the difficult processing problems of the complex parts and improve the process quality and production efficiency. is the method has the advangtages of advanced, scientific and practical etc..

Abstract: Recently the technology of the trenchless drilling of road construction is developing fast as a new technology. However the problem of fault diagnosis in the trenchless drilling pneumatic impact device which works under ground puzzles users frequently. Combined the traditional vibration diagnosis technology with the grey relational theory, a novel grey fault diagnosis approach is presented. With the grey relational degree used to make cluster analysis, the on-line monitoring and diagnosis is realized. The experiment results show that this method is highly reliable and the stucture is very simple.
