Abstract

In this paper, an efficient approach for sheet metal thickness measurement is proposed. It is based on the concept of magnetic field effect resonance commonly called as Hall effect. The combination of magnet and metal tool generates the DC voltage signal. The magnitude of generated signal is inversely proportional to the distance between magnet and tool and hence the thickness of the sheet metal. The proposed idea is designed and implemented successfully using a suitable hardware. Initially, the designed circuit is tested manually using the Hall-effect sensor and the sheet metal of different thickness. Further, the various experimentations are carried out on the complete CNC machine-based incremental sheet metal forming setup to examine the effectuality of the proposed design. Moreover, the evaluation of the manufactured ISF part has been carried out using the image processing technique. It is observed that the proposed approach can be used efficiently in the application such as incremental sheet metal forming (ISF) process in real time for thickness measurement.
