the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

Efforts to reduce COx are extremely important, which forces the use of materials and technologies that weight means transport in order energy consumption. Currently, aluminum alloys FRP composites still too expensive for mass industry applications. Presented this study, Litecor is a three-layer composite combines high strength steel with low density plastic. Thanks external covers 0.3 mm thick ...

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...

With a view to improving the surface quality of magnesium (Mg) alloy at warm temperature, ultrasonic-assisted single-point incremental forming (SPIF) is proposed. The Mg during SPIF primarily affected by two parts: orange peel patterns non-contact and scratches adhesive wear contact surface. In this work, AZ31B sheet parts different temperatures ultrasonic amplitudes evaluated examining roughne...

in recent years, in order to reducing die design and manufacturing costs, multi point forming technique has gained an increasing interest because of its high flexibility. in this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. in this paper, the fundamental principles of multi-point forming was described and the possib...

In Incremental sheet metal forming process, one important step is to produce tool path, an accurate path of the main challenge incremental process. Various factors should be considered prior generation i.e. mechanical properties metal, holding mechanism, speed, feed rate and size. this work investigation studies have been carried out find different strategies control twist effect in final produ...
