in forging design the significant parameters are maximum load or energy which are required for the selection of forging press or hammer. these two parameters are varied by the other paramelers such as the geometry of die cavity, flash dimensions, shape of the work piece, friction, mechanical properties of the metal to be forged, temperature, strain rate, and number of the forging operation. the...

Forging is a manufacturing process that consists of shaping the metal using localized compression forces. The blows are delivered with a hammer (often an electric hammer) or a die. In this paper, different methods of forging (multi-directional forging, hot forging, near-beta forging, multi-axial forging, direct powder forging, warm forging and ring forging) are discussed. The main problems that...

Purpose: To predict the minimum value of additional material volume for an acceptable preform product. To predict an acceptable preform product without shape defect such as unfilling in a closed-die forging operation. Design/methodology/approach: In order to reduce the number of experiments, an orthogonal array from the Taguchi’s experimental method will be utilized to design the process parame...

We have been developing a process design CAE system to predict die wear life in the process design stage for the hot forging of steel. Our goal is to reduce production costs by shortening the development period, while maximizing the life of the die. In our system, we use an expression that defines the relationship between die wear, die strength, and friction factors, such as die pressure, slidi...

The study proposes processing animation simulation, FEM analysis, and experimental verification of multi-stage forging of stainless automotive battery fastener. The processing animation simulation can provide the realistic motions for each pass to realize how to work for the front punch and die. Stainless automotive battery fastener requires high dimension precision and narrow tolerance. In ord...
