| Abstract | In order to improve the quality of the robot automatic polishing on curved surfaces and ensure the constant polishing pressure during polishing process, the polishing platform was built and the polishing process was studied. According to the Preston equation and Hertz theory, the relation model between removal rate and polishing pressure was established. The importance of constant polishing pressure control was analyzed, and the model of polishing pressure control was established. At the same time, the main factors influencing polishing pressure were discussed and experiments were carried out. The results indicate that the generation algorithm of the position and posture for robot polishing tool, instead of the traditional complex teaching process on the robot, was proposed based on force-position-posture decouple control, which realizes the robot automatic polishing similar to experienced constant pressure manual polishing. Through the force analysis of the sensor measurement, the gravity compensation algorithm of the polishing tool was put forward, which was used to eliminate the interference caused by gravity during machining to accomplish the stable control of polishing pressure. During the automatic polishing process with constant pressure control algorithm, the consistency of polishing pressure was better than that of without force control. Not only is the machining allowance removal uniform, but also the surface quality is greatly improved. The experimental system platform can control the polishing pressure during the polishing process independently, automatically, and in real-time, and accomplish ultra precise, efficient, low-cost polishing on curved surfaces. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
