Circle grid analysis provides very accurate, fast and non-expensive answers how the parts can be formed better, at what stage the problem occurs, how the lubricant and design can be improved, and what factors are the ones affecting the forming process most seriously. It helps greatly to avoid very expensive “trial & error”- process. The results are quantified very precisely, expressed by the major and minor strain values, as well as by the changing of the thickness of the sheet, and presented in a very easy-to-understand graphical form. In order to lower your testing expenses, we definitely can help in designing the experiment and determine how to approach the problem.
The following is a very simplified procedure which presents the major steps of the analysis: Testing procedure
