Five-axis NURBS Path Real-time Generation Method in CNC System [PDF]
International Journal of Advancements in Computing Technology, 2010 Abstract A real-time path generation method with Non Uniform Rational B Spline(NURBS) technology in the Computer Aided Design(CAD) field is presented and realized in a five-axis Computer Numerically Controlled(CNC) system. In this method, the tool path was represented into two NURBS curves, tooltip and tool-orientation spline curve, based on the same ...

Modeling and verification of a five-axis laser scanning system
The International Journal of Advanced Manufacturing Technology, 2005Today several new kinds of laser beam sensors appear with high resolution and accuracy and find their applications in reverse engineering and quality control. Due to the incapability of changing their orientations continuously in response to the surface fluctuation of a part to be measured, they are not competent for measuring parts with complicated ...

Development of a five-axis postprocessor system with a nutating head
Journal of Materials Processing Technology, 2007Abstract A postprocessor capable of converting the cutter location data to machine control data is an important interface between the NC programming design and manufacture. Owing to the fact that current research on multi-axis postprocessor methods only deals with machine tool configurations whose linear and rotational movements are orthogonal, this ...

Motion compensation for five‐axis rapid prototyping system
Rapid Prototyping Journal, 1998In view of the “staircase or stepped effect” in the present commercial rapid prototyping (RP) systems, a new approach is proposed, and is currently under development to produce true stepless parts. The new RP system is a combination of five‐axis motion control technology and precision milling.

Five-axis stabilization system for a 2-DOF translational OIS
2017 International Conference on Applied System Innovation (ICASI), 2017This study proposes a novel 5-axis stabilization system for a new two degree-of-freedom (DOF) translational optical image stabilizer (OIS) of cell cameras installed on the mobile phone. The OIS can improves the blurring image caused by the hand shakings when shooting a picture because the OIS stabilize the movements of the lens holder to efficiently ...

Practical Demonstration Of A Learning Control System For A Five-Axis Industrial Robot
SPIE Proceedings, 1989The overall complexity of many robotic control problems, and the ideal of a truly general robotic control system, have led to much discussion of the use of neural networks in robot control. This paper discusses a learning control technique which uses an extension of the CMAC network developed by Albus, and presents the results of real time control ...
