Development of process control in sheet metal forming.

Development of process control in sheet metal forming. Most problems in sheet metal forming come from a bad control of holding restraining and springback. Fig 5 basic elements of isf 5 cnc machine control the tool movement. A tool the tool used is hemispherical in design and blank holder is used to clamp the sheet metal.

Which is forming tool sheet metal blank holder and cnc machine as shown in fig 5. Schematic of a sheet metal forming process fig. Curling is a forming process that involves de burring sheet metal to produce smooth edges. The die at the top is called a punch.

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. 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 proposed development will be useful in designing and implementing process control in sheet metal forming processes as described in subsequent chapters. Problems of part quality in the sheet metal forming process.

Another common sheet metal forming process is bending. Companies typically perform bending on sheet metal using either a brake press or similar machine press. By doing so the sheet can be bent or stretched into a variety of complex shapes. 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.

One strategy for controlling sheet metal forming processes through the application of variable blank holder force is process control see fig. Blank holder restricts the movement of sheet metal going inward. Flange development and protection die entry line. Joins the punch line to the blankholder with an opening.

Process design is the ensemble of operations leading from the design geometry to. Sheet metal is formed cold. Read more conference paper. This is a commonly used manufacturing process that helps in manufacturing the parts for tons of known and unknown purposes.
