Title:
MULTIAXIAL ERROR CORRECTING DEVICE FOR MACHINE TOOL
Document Type and Number:
Japanese Patent JPH09230916
Kind Code:
A
Abstract:
To make adequate corrections on the whole by eliminating the influence of the movement of one axis upon an error of another axis.
When plural axes X and Y of movement are provided, this device divides the entire movement range S formed by the axes X and Y into plural areas R(R1-1-R1-n, R2-1... Rm-1-Rm-n) which are sectioned in the mutual relation of respective axis coordinates. A correction data storage means 29 is provided which stores correction quantities δx and δy for the axes X and Y by the areas R. When a moving body 7 is positioned in an arbitrary area R, an error correcting means 28 corrects movement quantities according to the correction quantities δx and δy corresponding to the area R.
