achieving optimal production cycle time for improving manufacturing processes is one of the common problems in production planning. during recent years, different approaches have been developed for solving this problem, but most of them assume that mean quality characteristic is constant over production run length and sets it on customer’s target value. however, the process mean may drift from ...

Monitoring, control and improvement of quality are  important  for companies.  Process capability indices (PCIs) are tools widely used by the industries to determine  the quality of their products and the performance of their manufacturing processes. Classic versions of  these  indices were constructed for processes whose quality characteristics have  a  normal distribution. But, many of these ...

Aimed at overcoming the disadvantages of traditional selective assembly and improving the manufacturing processes of mating parts, a new approach of information-based manufacturing for the mating parts of selective assembly via a coordinated statistical tolerancing (ST) and SPC model is presented. On the basis of studies on quality indices and process capability index (PCI), particularly, the m...

Manufacturing companies today face fierce global competition and volatile and rising prices on an ever more restricted natural raw material supply market. Customers demand high quality of the purchased products and supplying companies have to find ways to fulfill these customer requirements. In general, there are two ways how companies can meet specific requirements when material properties are...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...

Abstract: We present the optimization of the manufacturing process of the 5nm bulk-FinFET technology by using the 3D process and device simulations. In this paper, bysimulating the manufacturing processes, we focus on optimizing the manufacturingprocess to improve the drive current of the 5nm FinFET. The improvement of drivecurrent is one of the most important issues in ...
