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.

An interpolation method based on tool orientation fitting in five-axis CNC machining
2016 IEEE 14th International Conference on Industrial Informatics (INDIN), 2016The currently existing five-axis CNC machining systems tend to employ linear interpolation algorithm in machining, which will result in nonlinear errors and abrupt tool orientation changes due to ignoring tool orientation interpolation. To overcome those disadvantages, a tool path interpolation method that takes tool orientation interpolation into ...
