Introduction
Local Fluctuation Forming and Its Characteristics
Local fluctuation forming is a type of forming technology that is used to deform a workpiece by pressing it with a forming tool at an appropriate speed, achiieving a certain shape. The workpiece is subjected to local forming by the application of simultaneously intermittent forming forces from cutting, bending, stretching and rolling. This technology has many advantages such as 1) rapid prototype manufacturing; 2) greater flexibility in the design; 3) materials can be used for forming process depending upon the particular application; and 4) high-precision parts could be produced.
Discussion
Local fluctuation forming can be used for forming materials such as metals, plastics and composites, depending on the application. It is typically used for producing small- to medium-sized parts, as it requires a high level of precision. The process involves the application of simultaneous intermittent forming forces that result in deformation of the work piece at specific areas. The forces used in local fluctuation forming are based on an analysis of the material, to determine the right intensity and points of application. The design of the forming tool also needs to be taken into account while choosing a forming technique, in order to ensure that the part is being deformed accurately.
The primary benefit of local fluctuation forming is the production of parts with a high degree of precision and accuracy. Since the forces are applied locally, the heat generated during the process is minimal, resulting in a consistent quality of parts produced. It also eliminates the need for subsequent anneling or machining of the parts, resulting in cost savings for the manufacturer.
Local fluctuation forming processes are further characterized by the following properties:
1. High Strength: This process requires the application of strong and simultaneous forces, resulting inhigh strength parts with a long service life.
2. Flexibility in Design: As the forces used during local fluctuation forming can be varied, it allows for greater flexibility in the design process.
3. High Precision:Parts produced using this method have high precision as the forces are distributed evenly during the forming process.
4. Short Cycle Time: Since the forces are applied directly to specific areas of the part, local fluctuation forming involves a short cycle time while ensuring high precision.
Conclusion
Local fluctuation forming is becoming increasingly popular as a forming technology due to its ability to produce high precision parts with a high degree of accuracy and strength. It is also highly flexible in terms of design, as well as being cost-effective due to its shorter cycle times. Considering these characteristics, local fluctuation forming can be a very useful solution for a vast range of applications.
