| Abstract | This paper presents a method of tool posture local collision-free area generation for 5-axis machining point clouds. Considering it is time-consuming and complicated to calculate the entire precise area, in this paper, discrete inclination angles are obtained in its available range, and the precise collision-free rotation angle ranges of each inclination angle are calculated to construct the collision-free area in 2-dimensional configuration space (C-space). In local gouging avoidance, an algorithm is presented to calculate the maximum equivalent tool radius with the local contour line of the point cloud near the cutter contact (CC) point, which defines the local gouging-free ranges of rotation angles and discrete inclination angles. In rear gouging avoidance, if the tool rotates by some specific angles, a rear gouging point will be outside the tool and the gouging is avoided. Based on the way, an algorithm is presented to calculate the gouging-free ranges for discrete inclination angles. Finally, the intersections of local and rear gouging-free rotation angle ranges define the collision-free area. This presented method applies to flat-end milling cutter and torus milling cutter, and two examples are given to illustrate the feasibility. |

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.
