Document Type and Number:
Japanese Patent JP4198861
Kind Code:
B2
Abstract:
In a multi-axis machine tool (M) including an angular dividing head (HD) having a spindle head (9) mounted thereto, the positional correction includes determining an error representative vector componentwise representative of a plurality of positional errors with respect to a plurality of axes of the spindle head at a respective angular position dividable by the angular dividing head, and correcting an arbitrary positional error of the spindle head by calculating a component vector of the error representative vector associated with the respective angular position.
