Modeling and Experimental Analysis of Effect of Tool Geometry on Single Point Incremental Sheet Metal Forming

Article July 11, 2017

Dieless manufacturing process involves progressive deformation of the sheet metal using a punch (or tool). During the incremental deformation process, the sheet may or may not be supported on its back side. There are various factors that affect the process of dieless sheet forming. The objective of this work is to identify the effect of tool geometry on formability of sheet metal components in the case of single point incremental sheet metal forming. For this purpose numbers of experiments have been performed with three different tool geometries, which are spherical tool, elliptical tool tip with straight diameter and elliptical tool tip with tapered diameter. The entire exercise has also been simulated in virtual environment and a good correlation between the simulation and the experimental work is observed. It has been observed that the results of the analysis would help to improve the selection of appropriate tool and obtain better forming limit for a given sheet metal.

Effect of Different UML Diagrams to Evaluate the Size Metric for Different Software Projects

Article January 18, 2016

In Software Engineering, an important activity is measuring of the Software in different ways. For Measuring the Software, appropriate metrics are needed. Using Software metrics we are able to attain the various qualitative and quantitative aspects of Software. To measure the Software in terms of quality, size, efforts, efficiency, and reliability, performance etc. we have different metrics available in Software Engineering and it has been an area of interest for the various researchers. Measures of specific attributes of the process, project and product are used to compute Software metrics. This work proposes a similar approach of measuring software using various UML diagrams and applied Software size metric to evaluate the size of the Software. This paper discusses the proposed approach using two different case studies and their source codes. This paper discusses the different results obtained using different perspectives of the Software size metric measurements and maintainability of the Software.
