| Abstract | Rigid tapping is a novel tapping process and is extensively used to produce internal threads on a manufactured mechanical part because of its precise and efficient performances. However, it is difficult in practice to design control gains for controlling rigid tapping processes using systematic approaches because the operational environments in the rigid tapping processes are usually unknown and cannot be predicted or modeled precisely. Tuning a set of control gains that could achieve good tapping results in rigid tapping processes is therefore a great challenge for users. In this study, we investigate the use of the learning automata methodology in optimal tuning of the control gains of rigid tapping processes operated under unknown operational environments. The rigid tapping results achieved on a CNC tapping machine indicate that the developed learning automata tuning method (consists of two tuning phases) can effectively tune the optimal control gains. As compared to tapping results where the control gains are obtained from a manual, the developed tuning method provides optimal control gains so that the CNC tapping machine efficiently and precisely produces internal threads that pass thread gauge tests. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
