Using features to aid process planning and resolve manufacturability problems cheng hua wang and david a.

Process planning sheet metal parts. Of course there is always a substantial cost difference when a part is mass produced. Bourne the robotics institute carnegie mellon university pittsburgh pa 15213 usa robotics and computer integrated manufacturing vol. Engineers designing sheet metal parts should understand the importance of bend relief and how it helps avoid torn metal and that features like beads and flanges serve specific purposes. In this domain general purpose cnc machinery and standard tools are being used.

In process planning the cad part data is used to define the number of operations necessary to form the part as well as the operation sequence. Sheet metal forming process is done on a press and the parts are formed in between two die. Also called three view drawing. Quick forming check.

There are a few different ways this can be. Draw the expansion diagram. You can very quickly create alternative process concepts to produce quality and cost effective parts. Guidelines for process planning of sheet metal parts produced on compound die from the critical review of published literature and detailed discussions with experienced die designers some basic guidelines for process planning of sheet metal parts pro duced on compound die are identified 1 9 10 14 18.

Sheet metal processing process according to the difference in the structure of the sheet metal parts the process flow may be different but the total does not exceed the following points. The die at the top is called a punch. An example of a process planning system is given and some areas of special interest are discussed in more detail. Sheet metal forming processes.

Prototypes are actually created using the exact same process as mass produced sheet metal parts. The paper describes process planning for order based small batch sheet metal part manufacturing. 1 blanking blanking way there are various mainly in the following ways 1 shears. Sheet metal is formed cold.

Design and manufacturing of sheet metal parts. Process planning for sheet bending and tolerance reasoning are important and intricate tasks within. The sheet metal technological process may vary but not more than the following stated 10 processes. Which is to expand the parts with complex structure into a flat.

Shears are used to cut strips of simple materials. How is sheet metal cut. This is a commonly used manufacturing process that helps in manufacturing the parts for tons of known and unknown purposes. Its role is to express the structure of sheet metal parts by drawing.
