| Abstract | This paper presents a practical approach to applying variable spindle speed machining (VSM) to noncircular turning process, in which the cutting tool is driven by a fast tool servo and performs dynamic variable depth of cut machining. An enhanced closed loop dynamic model involving strong dynamic feedback between the machining process and the fast tool servo is thus developed. By using the spindle’s angular position as the independent variable and Euler differential approximation, the system dynamics are described as a finite dimensional periodic time-varying discrete system, which in turn is converted to a time-invariant system using the lifted technique. The system stability becomes tractable by spectral radius analysis. Then, a criterion of the VSM stability index is used to evaluate the quantitative effects of VSM on noncircular turning systems and to design optimal VSM trajectory parameters. It is shown that a modest stability increase is obtained with the use of VSM. Experimental machining results are presented, which demonstrate the ability to increase noncircular turning stability using VSM, as well as the proposed VSM trajectory parameters design. |

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.
