In the article the changes associated with construction of machines used in die and die-less sheet metal forming have been presented. The selected future directions of development in new technologies and machines for sheet metal forming taking into account modern blank holding systems in the process of deep drawing have been indicated. Also the tendencies in introduction of new technologies and...

In this paper, Computer Aided Designing (CAD) in conjunction with Rapid Tooling is applied to design and produce forming tools (punch and die) for stretch-formed jewelry (generated on thin sheet metal on top of which jewelry patterns are raised with forming tools by stretching the sheet metal beyond its elastic limit. The work presents a parametric voxel based CAD paradigm for modeling of such ...

The present paper explains a feature recognition module and design advisor system for sheet metal components. In this system features of sheet metal components are extracted automatically from 3-D model. These data are modeled based on object oriented. The proposed system will aid the designer right at the design stage with useful design and manufacturability recommendations that have been gath...

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...

The process of designing new industrial products is in many cases solely based on the intuition and experience of the responsible design engineer. The aid of computers is restricted to visualization and manual manipulation tools. We demonstrate that the design process for conduits, which are made out of sheet metal plates, can be supported bymathematical optimizationmodels and solution techniqu...

INTRODUCTION Slip Mounted Single Point Deformation expands upon the ideas of single point incremental metal forming, using a 6-axis robotic arm, by exploring the possibilities of how sheet metal can be deformed with minimal support bracing. The goal of this technique and research is to develop controlled methods for fabricating precise, double-curved, structural panels. The slip mounted techniq...

Offset curves have many applications in computer-aided design and manufacturing. The paper deals with sheet-metal design, where section curves that lie on a design surface must be offset by one metal thickness. Standard techniques for offsetting curves and surfaces are usually too slow for interactive speeds. The paper presents a simple iterative method for computing offset points which can the...

Bend sequencing and tool selection have long been the main hurdles for achieving automatic process planning for sheet metal bending. In this unique process, the complex shape and position transitions of workpieces make it hard to obtain a collision-free operation plan. The time-consuming involvement of human experts is often required to solve more complex problems. This paper presents a tool se...
