Abstract With the continuous advancement of computer technology, finite element simulation has been gradually applied to the analysis of plastic deformation of metals. If a strong spinning simulation model of 20 steel cylindrical parts can be established to effectively simulate the stress, strain and surface quality of the metal deformation process, it can provide a scientific basis for the setting of spinning process parameters, thus reducing the number of spinning process experiments to determine spinning process parameters.

In order to study the influence of process parameters on forming quality of printer board with metal-insert,shorten the development cycle,reduce the enterprise cost,the warp trend and reasons of injection process parameters,including packing time,hold pressure,mold temperature,melt temperature,on the warpage of the part were analyzed by means of software moldflow. The results show that warpage amounts decreases with packing time and hold pressure increasing,larger packing time and longer hold pressure is advantageous to the injection parts molding;And warpage amounts increases with mold temperature and melt temperature increasing,the lower mold temperature and melt temperature is advantageous to the injection parts molding;Among the four parameters,the melt temperature had the greatest influence,followed by the mold temperature and the hold pressure,packing time had the minimal influence on the warpage.

Abstract The clinched process of heterogeneous materials is more and more used in automobile, aerospace, and household appliances manufacturing. Traditional spot welding is easy to produce heat influence and damage material itself, which restricts the application and development for the hybrid structure of the vehicle body. This paper is based on the test of clinching. The cross-section morphology of clinched joints is observed. Based on the tensile test data and the requirements of the test die, the finite element model of the steel-aluminum clinched joint forming is established. The model is proved to be effective in the process of clinched forming. Based on the simulation model, the influence of process parameters (forming process parameters, Punch’s geometry parameters, and concave die structural parameters) on the forming quality of steel- aluminum clinched joint is analyzed. The evaluation of the joint after forming includes the critical dimension, deformation, and neck-lock ratio. Then, the strength of the steel-aluminum clinched joint was studied by tensile shear test. The law of strength change and the neck-lock ratio is analyzed. The selection strategy of different process parameters is studied. The results show that the forming process of the joint is predicted by numerical simulation, and the quality of the joint is sound. The neck-lock ratio of the joint with the highest tensile and shear strength is less than one and close to 1, that is, the joint with forming force of 40kN. The tensile strength and shear strength of clinched joint are higher than the design index (shear strength is 1700N, tensile strength is 700N). The tensile strength was increased by 125%, and the shear strength was 62.35%.

Stamping process is a complex system, in the case of determined sheets, whether it can produce qualified parts has a great relationship with the setting of mold process parameters. Therefore, whether it is reasonable, the structure parameters of the parts are directly related to the forming quality of sheets. This paper uses the finite element numerical simulation, by setting different process parameters for single-factor simulation study, combines with the designers’ experience and repeats simulations to find the appropriate range of factors, and to obtain the optimum process parameters, thereby reducing repeated mold testing and repair costs, shorting the development time of new products.

Abstract The steel wheel consists of wheel disc and rim. The wheel disc is manufactured by using power spinning process. The spinning process does not guarantee that the design scheme can be realized accurately. In this paper, the simulation method of the disc spinning process is investigated, and introduced to the lightweight design of steel wheel. Firstly, the power spinning process is simulated, and the validity of the simulation method is verified by test. Then two optimization schemes of the disc are proposed. Finally, the forming quality of the products from the optimization schemes is analyzed by spinning process simulation. The results show that the product from the optimal scheme may not be optimal since the effect of the forming quality in the spinning process. To obtain the optimal performance of product, it is very necessary to evaluate the design scheme by introducing the disc spinning process in the design stage of wheel disc.

This paper is an attempt to assess if the manufacturing process of paper machine is in statistical control thereby improving the quality of paper being produced in a paper industry at the time of process itself. Quality is the foremost criteria for achieving the business target. Therefore, emphasis was made on controlling the quality of paper at the time of manufacturing process itself, rather than checking the finished lots at a later time.  This control on quality will help the industry deduct the small shift in the process parameters and modify the operating characteristics at the time of production itself rather than receiving complaints from customers at a later stage.  This paper describes controlling quality at the time of manufacture itself and helps the industry to concentrate on quality at low cost. The researcher has collected primary data at a leading paper industry during October, 2019.  Though X-bar and Range charges were primarily used, CUSUM charts were used to sense the minor shifts in manufacturing process, to explore the possibility of adjusting process parameters during manufacture of paper.
