Process Control For Sheet Metal Stamping

The use of process control for sheet metal stamping greatly reduces defects in deep drawn parts and can also yield large material savings from reduced scrap.

Process control for sheet metal stamping.

Process control for sheet metal stamping presents a comprehensive and structured approach to the design and implementation of controllers for the sheet metal stamping process. These designs are then translated into stamping dies by skilled craftsmen known as diemakers. Power press with a fixed barrier guard. The use of process control for sheet metal stamping greatly reduces defects in deep drawn parts and can also yield large material savings from reduced scrap.

Process control for sheet metal stamping allows the reader to design and implement process controllers in a typical manufacturing environment by retrofitting standard hydraulic or mechanical stamping presses and as such will be of interest to practising engineers working in metal working automotive and aeronautical industries. 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. Sheet metal forming is a complex process and most often characterized by partial differential equations that are numerically solved using finite element techniques. Embossing is a process for creating either a raised or recessed design in sheet metal by pressing the raw blank against a die that contains the desired shape or by passing the material blank through a roller die.

These parts achieve their shape through the effects of the die tooling. Sheet metal stamping stamping presses and stamping dies are tools used to produce high volume sheet metal parts. They are commonly developed using computer aided design cad software and analytical programs to create and prove out highly accurate unambiguous designs. Process control for sheet metal stamping presents a comprehensive and structured approach to the design and implementation of controllers for the sheet metal stamping process.

The metal stamping process may involve one or more of the following actions. Once these stamping dies are mounted into presses sheet metal is fed to them. Coining is a bending technique wherein the workpiece is stamped while placed between a die and the punch or press. 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.

Production stamping is generally performed on materials 020 to 080 thick but the process also can be applied to foils as thin as 001 or to plate. Sheet metal forming is a complex process and most often characterized by partial differential equations that are numerically solved using finite element techniques.
