Development Of Process Control In Sheet Metal Forming

Curling is a forming process that involves de burring sheet metal to produce smooth edges.

Development of process control in sheet metal forming.

Companies typically perform bending on sheet metal using either a brake press or similar machine press. Which is forming tool sheet metal blank holder and cnc machine as shown in fig 5. The sheet metal is placed over a die block at which point a punch presses down. Blank holder restricts the movement of sheet metal going inward.

A tool the tool used is hemispherical in design and blank holder is used to clamp the sheet metal. Sheet metal is formed cold. The die at the top is called a punch. Flange development and protection die entry line.

A wrinkling b tearing and c springback 1 2 background to overcome production problems tool and die manufacturers continuously integrate new techniques and ideas in sheet metal forming in their design. 3 in this strategy a measurable process variable e g punch force is controlled by following a predetermined e g punch force displacement reference trajectory through manipulating the blank holder force. Sheet metal forming processes. Joins the punch line to the blankholder with an opening.

The proposed development will be useful in designing and implementing process control in sheet metal forming processes as described in subsequent chapters. This is a commonly used manufacturing process that helps in manufacturing the parts for tons of known and unknown purposes. Read more conference paper. Sheet metal forming process is done on a press and the parts are formed in between two die.

Development of process control in sheet metal forming. Problems of part quality in the sheet metal forming process. By doing so the sheet can be bent or stretched into a variety of complex shapes. Schematic of a sheet metal forming process fig.

Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. Process design is the ensemble of operations leading from the design geometry to. One strategy for controlling sheet metal forming processes through the application of variable blank holder force is process control see fig.
