Necessity of using of metals in many kinds and shapes in human different activities, has always obliged him by invention of new ways, plods in forming and transfiguration of metal parts field Among the new methods in sheet metal forming, in this research, has been studied a new technique called “Incremental Sheet Metal Forming”.The process locally deforms sheet metal using a moving tool head achieving higher forming limits than those of conventional sheet metal stamping process. The die-less nature in incremental forming provides a competitive alternative for economically and effectively fabricating low-volume functional sheet products. Potential application areas include aerospace industries, customized products in biomedical applications and prototyping in the automotive industry. This new forming method is especially suitable for small batch production and rapid prototyping of sheet metal parts. In this process, sheet metal is inserted on a punch with special shape in order to produce required deformation by incremental movement of forming tool. Therefore, creation of complex shapes from sheet metals is achieved. .In this way, via the incremental movement in the forming tools using Computer Numerical Controlled machine, suitable form in sheet is produced. This project has been surveyed experimental and laboratory approaches of TPIF technique. In other words, one of the important objectives of this project is required equipment preparing and gaining of ability in ISMF performance. Because, always in practical space of a process, there are specific conditions and parameters that, adequate control over these factors and also the ability in performance of fine and full tests of one method, is very important. Experimental tests have been performed .wwwith regard to the aluminum and brass sheets in various thicknesses. Also, in order to ensure from the proper performance of tests, among some of the important parameters in the test results and correlate references, is presented a complete comparison..Moreover, in this research force as important and influential parameter in a forming process is measured. Indeed, depending on the sheet material, thickness and etc, considerable forces can occur. A good knowledge of these forming forces can contribute to the preservation of the tooling and the machinery used in the process. Also has been investigated effect of four parameter, tool diameter, sheet thickness, vertical step down of tool and kind of tool movement on process force and formability of sheet metal.It should be noted that, in this effort the measurement and online observation of process force, has been implemented by two loadcell sensors and LabVIEW software that is new and innovative method.
