the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

today, the development of agricultural industries, especially small and efficient agricultural sector has been paid more attention. the development of rural industries in the country led to job creation and absorption of surplus labor force in agriculture and also resulted in more exports and foreign exchange. this paper evaluates development indicators of process industries and accesses to reg...

in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

this paper presents the results of the assembly process of a gasketed bolted flanged pipe joint for two different bolt tightening strategies, i.e. asme and industrial using torque control of preload method.  the final clamping force is achieved in four and five passes in asme and industrial strategy respectively. axial bolt stress variation, at the end of each pass, individual bolt bending beha...
