Tool-path planning for direction-parallel area milling
CAD Computer Aided Design, 2000Abstract Presented in the paper is a tool-path planning algorithm for direction-parallel area milling consisting of three modules: (1) finding the optimal inclination; (2) calculating and storing tool-path elements; and (3) tool-path linking. For the optimal inclination, we suggest an algorithm that selects an inclination by reflecting the shape of ...

Tool Orientation Optimization and Path Planning for 5-Axis Machining
Journal of Systems Science and Complexity, 2020Tool path generation is a fundamental problem in 5-axis CNC machining, which consists of tool orientation planning and cutter-contact (CC) point planning. The planning strategy highly depends on the type of tool cutters. For ball-end cutters, the tool orientation and CC point location can be planned separately; while for flat end cutters, the two are ...

Tool Path Planning for Compound Surfaces in Spray Forming Processes
IEEE Transactions on Automation Science and Engineering, 2005Spray forming is an emerging manufacturing process. The automated tool planning for this process is a nontrivial problem, especially for geometry-complicated parts consisting of multiple freeform surfaces. Existing tool planning approaches are not able to deal with this kind of compound surface.

Tool path planning for 3-axis machining
International Journal of Manufacturing Research, 20063½½-axis machining combines the flexibility of orientation offered by five-axis machines with the ease of programming offered by three-axis machines. In 3½½-axis machining the surface is divided into patches and the tool orientation is locked during the cutting of each patch.

Tool path planning for aspheric five-axis machine tools
AOPC 2019: Optical Spectroscopy and Imaging, 2019Aspheric surfaces are widely used in modern optical systems. At present, five-axis machine tools are widely used for aspheric surfaces grinding and shaping. The technology of milling aspheric surface with five-axis machine tool is studied. According to the B-C double turntable five-axis machine tool, its kinematics model is analyzed.
