We gratefully acknowledge the opportunity to collaborate with the research team at IIT – Madras along with the industrial partner (Micromatic Grinding Technologies – MGTL). This collaboration has resulted in the development of a portable/mobile diagnostic tool for precision grinding processes, in a record time. The tool has been developed at IIT – Madras and has been validated in the industry through MGTL. This tool has also been used as a tool for the past three years, for teaching grinding science for use by practice oriented engineers and managers in leading manufacturing companies in India. We also acknowledge the collaboration with IMTMA – an industry organization. This is an excellent example of Knowledge Integration and development of manufacturing eco-system based on Inter-industry collaboration, promoted by the STIMS Institute as the foundation for Next Generation Manufacturing.

Abstract: This paper presents an approach to develop a diagnostic tool that can monitor the power drawn by the spindle motor using a power sensor and infeed of grinding wheel using a linear variable differential transformer (LVDT) in cylindrical grinding machine. A combination of spindle power and wheel infeed measurement enables the performance evaluation of grinding process. This evaluation suggests the possibility of optimizing the grinding cycle in order to enhance the efficiency of grinding process. The effectiveness of the developed in-process, portable diagnostic tool is demonstrated with a case study.
