In this work, incremental sheet forming of a complicated shape is investigated experimentally. Two point incremental forming with negative and positive dies are employed for manufacturing of a complicated shape with positive and negative truncated cones. The material is aluminum alloy 3105 with a thickness of 1 mm. The effects of process parameters such as sequence of positive and negative form...

Single point incremental forming (SPIF) that will produce non-symmetric sheet metal parts has been rarely dealt with so far. SPIF of a Francis hydro-turbine vane made aluminum alloy is studied as typical example in this work. At first, concave geometry, encompassing the desired shape designed, from which formed part be ultimately cut out. The necessary toolpaths are created by using CAM softwar...

This paper proposes the exchange market algorithm (EMA) to solve the combined economic and emission dispatch (CEED) problems in thermal power plants. The EMA is a new, robust and efficient algorithm to exploit the global optimum point in optimization problems. Existence of two seeking operators in EMA provides a high ability in exploiting global optimum point. In order to show the capabilities ...

‎we prove the existence of ppf dependent coincidence points for a pair of single-valued and multi-valued mappings satisfying generalized contractive conditions in banach spaces‎. ‎furthermore, the ppf dependent fixed point and ppf dependent common fixed point theorems for multi-valued mappings are proved.

The present paper proposes a numerical-experimental comparative study on the single point incremental forming process. A DC04 steel sheet with thickness of 0.6 mm was used for both numerical simulation using finite element method and experimental research. type trajectory spiral finished part obtained truncated cone-shaped part. analysis program Ls-Dyna. simulations were performed in several va...
