Adaptive nonlinear tool path optimization for five-axis machining

International Journal of Production Research, 2000
Current tool path computation in the CAM algorithms approximates the surface by piecewise linear interpolation. In the case of three-axis machining on a CNC machine the tool will exactly reproduce this computed tool path. However in the case of five-axis simultaneous machining the real tool path on the CNC machine will not follow the linear ...

Inverse solution optimization of universal five-axis machine tools

Proceeding of the 11th World Congress on Intelligent Control and Automation, 2014
Inverse solution of five-axis machine tool is that given the excepted point of tool-tip and the excepted vector of tool-axis to solve the G codes of five axes, it is the key step of five-axis machining. Based on the exponential product method, this paper proposed the inverse solution which is general and applicable to any form of orthogonal and non ...

A Machining Test to Reflect Dynamic Machining Accuracy of Five-Axis Machine Tools

Advanced Materials Research, 2012
NAS (National Aerospace Standard) 979 is the only standard well known in industry describing a five-axis machining test for measuring kinematic errors of five-axis machine tools. As it cannot reflect the tool path characteristics of typical ruled surface machining, five-axis machine tools which passed the NAS test may not have the ability to satisfy ...

Machining accuracy improvement of five-axis machine tools by geometric error compensation

International Conference on Advanced Technology of Design and Manufacture (ATDM 2010), 2010
In five-axis machining, geometric error of the machine tool is an important error source reducing machining accuracy. Through geometric error compensation, the machining accuracy can be improved. A software-based error compensation strategy is discussed in this study.

High speed contouring control strategy for five-axis machine tools

CIRP Annals, 2010
Abstract Accurate contouring of five-axis tool-paths with CNC machine tools is important in high speed machining of dies, molds and aerospace parts having sculptured surfaces. This paper presents a new control approach where all five drives of the machine tool are controlled simultaneously with an objective of minimizing contouring errors. Contouring

Five-axis milling machine tool kinematic chain design and analysis

International Journal of Machine Tools and Manufacture, 2002
Five-axis CNC machining centers have become quite common today. The kinematics of most of the machines are based on a rectangular Cartesian coordinate system. This paper classifies the possible conceptual designs and actual existing implementations based on the theoretically possible combinations of the degrees of freedom.
