Development Of Process Control In Sheet Metal Forming

Problems of part quality in the sheet metal forming process.

Development of process control in sheet metal forming.

Sheet metal forming processes. Curling is a forming process that involves de burring sheet metal to produce smooth edges. This is a commonly used manufacturing process that helps in manufacturing the parts for tons of known and unknown purposes. Blank holder restricts the movement of sheet metal going inward.

Development of process control in sheet metal forming. Flange development and protection die entry line. Fig 5 basic elements of isf 5 cnc machine control the tool movement. Joins the punch line to the blankholder with an opening.

Which is forming tool sheet metal blank holder and cnc machine as shown in fig 5. Most problems in sheet metal forming come from a bad control of holding restraining and springback. One strategy for controlling sheet metal forming processes through the application of variable blank holder force is process control see fig. The sheet metal is placed over a die block at which point a punch presses down.

The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. 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. The die at the top is called a punch. Sheet metal forming process is done on a press and the parts are formed in between two die.

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. By doing so the sheet can be bent or stretched into a variety of complex shapes. Companies typically perform bending on sheet metal using either a brake press or similar machine press. A tool the tool used is hemispherical in design and blank holder is used to clamp the sheet metal.
