Abstract
A machining apparatus for making the scroll parts comprising a headstock including a spindle for supporting a workpiece for rotation, a tool holder for supporting a machining tool, a first carriage supported for movement in a direction perpendicular to the spindle (an X-axis), a second carriage supported for movement in a direction parallel to the spindle, and a control device for controlling the movement of the first carriage and the rotation of the spindle according. The control device is so programmed as to calculate the distance between the center of the base circle generating a desired involute curve depicted by the scroll parts and the center of the machining tool and also to calculate the angle of rotation C of the spindle relative to the distance.
