Abstract
A 5-axis processing machine includes a mounting table on which a tool and a work piece are placed; and a control unit; wherein the mounting table is moved relatively by three linear axes and two rotation axes based on NC data, the two rotation axes include a first axis and a second axis, when the control unit calculates a rotation angle of the two rotation axes, the control unit acquires an axis vector Na that specifies an actual first axis direction and an axis vector Nc that specifies an actual second axis direction, the control unit calculates a posture vector K that specifies a posture at a time of processing the work piece with respect to the tool from the NC data, the control unit calculates, as a solution of a following equation (4), an actual rotation angle θ around the first axis of the tool.
