![]() ![]() Quick-return mechanism design and kinematic analysis has received a lot of attention. As the disc rotates the top of the machine, ram moves forwards and backwards, pushing a cutting tool. The gear box last driven gears is used as a rotating disk. The reciprocating motion of the mechanism inside the shaping machine is obtained by using quick return mechanism. The main parts include a gear box, rocker, floating link, ram tool holder, casing, base and a table. However, it can also be used to manufacture gears such as rack and pinion systems and other complex shapes. ![]() It is used to remove material, usually metals such as steel or aluminum, to produce a flat surface. The shaping machine is a simple and yet extremely effective machine. Other machines such as milling machines are much more expensive and are more suited to removing smaller amounts of metal, very accurately. The shaping machine is used to machine flat metal surfaces especially where a large amount of metal has to be removed. Introduction Shapers were very common in industrial production. Key Words: Dynamic, Deformation, Frequency, kinematic & shaper. ![]() Using Virtual Prototyping techniques, engineers are able to shorten the design time and therefore shorten the time needed for pushing to market new products. Finite element analyses of machine parts in static and modal domains are carried out on machine parts and their subassemblies. Kinematic analysis defined position of shaper quick return mechanisms links, motion of ram, end of the rocker and machine crank as well as the displacement, velocity and acceleration of machine ram or cutting tool for different values of crank length and number of strokes per minutes. Several software like Matlab, Excel, Ansys and Solidworks has been used for remodelling and analysis. The structural behaviour under static and dynamic loads is evaluated in order to obtain an optimized design of the shaper machine elements. Shaper machine produced by the Egyptian Machine Tool Factory is selected for this study. This paper presents the current state of virtual prototyping of a shaper machine tool the work focuses on the design of the machine tool structure, main gear box, tool shank and tool holder systems. Shaper machine was remodelled for more static, kinematic and dynamic analyses. Shaper machine has received limited attention regarding their dynamic and static behaviour. Asy Department of Production Engineering & Mechanical Design University of Menoufia Shebin El-Kom, Menoufia, Egypt Abstract: Nowadays, machine tool builders can no longer have enough money to consume time and money building and testing real prototypes of the machine tool model, instead they use virtual prototypes. 1 Dynamic, Kinematic and Static Analysis of a Shaper Machine Prof. ![]()
