Automotive Sheet Steel Stamping Process Variation

Iso 9001 2015 certified automotive and custom metal stamping metal fabrication tool and die and welding service company.

Automotive sheet steel stamping process variation.

Simply saying that the stamping shop is through different molds loaded on the stamping machine to press the steel sheet into different sheet metal parts this is the main work of the automotive stamping shop. Withstanding variations in sheet metal propertiesto achieve robust stamping processes. This automotive body development report stamping process variation. An analysis of stamping process capability and implications for design die tryout and process control authors.

Metal stamping is a cold forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. In the same manner a designed sheet metal forming process should also function under worst conditions. Alternatively it can be a solid block of metal in a cubical or lens like shape. When you design a component of an automobile household machines or anything you want to be sure that this part would be safe under worst conditions car crash bad weather higher loading forces etc.

Stamping also known as pressing is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Numerous factors affect the observed variation in a stamping process making stamping one of the more difficult processes to control. Stamping includes a variety of sheet metal forming manufacturing processes such as punching using a machine press or stamping press blanking embossing bending flanging and coining. Characterize stamping variation by short term part to part long term die set to die set and mean bias long term deviation from design nomi nal to better understand process capability.

Pieces of flat sheet metal typically referred to as blanks is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. For automotive metal forming the blank is often made of sheet metal which can be stamped cut or bent into a shape needed for an automobile s body. An analysis of stamping process capability and implications for design die tryout and process control updates ongoing research activities by the body systems analysis team and the manufacturing systems staff at the university of michigan s office for the study of automotive transportation. The blank becomes the workpiece the piece of metal to be reshaped in the metal forming process.
