| Abstract | To enhance the efficiency of pocket machining, considerable researches on strategies of tool selection and tool path optimization have been conducted. However, few studies are devoted to tool path planning with consideration of hybrid tool path patterns and multi-cutter selection. This research gap leads to little promotion to industrial application of the available research results. This paper proposes an automated CNC programming approach considering both multiple cutters and hybrid tool path patterns for pockets machining with complex islands and curvilinear boundaries. Firstly, the largest cutter capacity (LCC) of a pocket, which restricts essentially the pocket machining time, is investigated and defined. Secondly, to enlarge the LCC and to generate optimal tool path more easily, the pocket is split into many sub-regions according to the bottleneck lines of its boundary. After subdivision, tool selection and path pattern determination rules for each sub-area are introduced, respectively. Then, several heuristic principles for region recombination are developed to minimize the number of sub-polygons. Besides, based on the soft edges of each sub-area, expansion technique is employed to generate machining bounds for residuals. Finally, to demonstrate the advantages of this approach, two examples are rendered. And, the results show that the presented method performs better than the conventional ways. |

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.
