Kinematic Reliability Analysis of Five-Axis Machine Tool
Advanced Materials Research, 2011Five-axis CNC machine tool is the top product of numerically controlled machine tool. Kinmatic accuracy is an important index to evaluate the quality of mechanism. Kinematic accuracy analysis of the Five-axis machine tool in previous study ignores the randomness of each input error component, so the conclusions are imprecise.

Tool path optimization in postprocessor of five-axis machine tools
The International Journal of Advanced Manufacturing Technology, 2013Generally, tool path is generated in a computer-aided manufacturing software considering only the geometry of machining parts. It is converted into numerical control (NC) codes in the postprocessor based on the particular machine kinematics. For some special types of five-axis machine tools, e.g., non-orthogonal five-axis machine tools, the generated ...

Machine models and tool motions for simulating five-axis machining
Computer-Aided Design, 2010This paper presents a method of determining the tool motion of a five-axis machine. The method is motivated by the imprint point method, where points on the machined surface are computed based on the tool position and tool motion. While simple linear motion can be used as a coarse approximation to this motion, this paper looks at more accurate models ...

Research on tool path planning for five-axis machining
2009 IEEE International Conference on Industrial Engineering and Engineering Management, 2009Tool path planning of CNC motion controller includes tool path interpolation and velocity planning. Five-axis machine tools have been adopted in mold surface and aerospace part machining. In this paper, the kinematics frame based on dual quaternion D-H representation was applied to define the coordinates of five-axis machines systematically ...

Tool path generation for five-axis machining of impellers
International Journal of Production Research, 1999This paper proposes a new tool path generation method for machining impellers with five-axis machines. Using the geometric characteristics of impellers, the proposed method first computes the tool path in the cylindrical coordinates and then converts it into the cartesian coordinates.

Modeling and Compensation for Five-Axis Machine Tool Errors
Manufacturing Science and Engineering: Volume 2 — Non-Traditional Design and Layered Manufacturing; Rolling Technology; Intelligent Machine Tool Systems; Measurement and Inspection of Products and Processes; Non-Traditional Manufacturing Processes of the 1990s, 1994Abstract A neural network based compensation strategy for five-axis machine tool error correction has been developed. It is capable of significantly reducing geometric, kinematic and thermal errors between the tool tip and the workpiece.

Five-axis CNC machine tool contour error control method
Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence, 2019In the five-axis CNC machining, various errors caused by factors such as geometrical accuracy and dynamic characteristics of the machine tool will eventually appear as the contour error of the part. Therefore, controlling and compensating for contour errors is of great significance.
