An improved algorithm for cross-coupling control of multi-axis machine tools

This paper presents an improved algorithm for cross-coupling controlled sys tems. In contrast to the existing algorithms, which must be re-formulated f or different types of curves and may be inconvenient to implement, the prop osed algorithm is adequate for general nonparametric and parametric curves. In addition, the proposed algorithm requires less computational time but a chieves the same performance as compared with the existing ones.
