How to reset the parameters of four-axis machining center

1, axis A is the third axis and then added to the fourth axis on the right. When the value of a is positive, it rotates clockwise, and when the value of a is negative, it rotates counterclockwise. The A60 axis can only rotate clockwise, and the A60 axis can only rotate counterclockwise, that is, the direction of rotation is determined by the sign of a.

2. The A axis of the machining center, that is, the 4 axis, also known as the B coordinate, is the axis that rotates around the xy plane. The usage method is to drag the work datum directly, and the angle after dragging is the angle of B coordinate, which is input into the reverse workpiece coordinate system.
