Incorporation of tool-life variables in NC path planning

International Journal of Production Research, 1992
An integration of tool-life variables with optimization studies is not evident in present literature. It is our belief however, that such an integration is required to make analytical NC path planning real. A two step process for analysing the tool path planning problem was carried out.

Spiral Tool Path Planning Using Eccentric Parameters

Volume 4: 19th Design for Manufacturing and the Life Cycle Conference; 8th International Conference on Micro- and Nanosystems, 2014
Free-form surfaces can be machined continuously with minimum tool retractions and at the high speed by following a spiral tool path. This paper presents an improved planning method of the spiral tool path using eccentric parameters for machining free-form surfaces. The relationship between a 3D machined surface and the 2D circular region is established

Non-singular tool path planning by translating tool orientations in C-space

The International Journal of Advanced Manufacturing Technology, 2014
This paper discusses the singular problem in five-axis machining of freeform surfaces. At first, the generating mechanism of the singularities is studied on the unit sphere in the P-system. Then a new method is developed to avoid the singularities by translating the tool orientations in the configuration-space (C-space) at the time just after the ...

Smooth Feedrate Planning and Trajectory Generation for Five-axis Tool Path

2019 IEEE 15th International Conference on Control and Automation (ICCA), 2019
This paper presents a real-time feedrate planning method with time synchronization and local corner smoothing algorithms to achieve high-quality five-axis machining. Linear and angular trajectories are planned by sharing motion time rather than curve parameter to realize synchronous motion for five-axis tool path. The maximum feedrate of linear segment

Optimal tool path planning for compound surfaces in spray forming processes

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
Spray 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 surfaces.
