To automatically recognize the hollows of a turning machining product and to decide a tool that is suitable to the hollow machining.
The finishing shape of a turning machining product is successively defined as segments AB, BC, CD... at a single end A of the finishing shape and traced for each of branch points B, C, D... at and after an intersection point A. If the machining product moves in its axial direction and also in the direction (minus direction of axis Z) opposite to the axial direction, the section set between both directions is decided as an end face hollow. If the machining product moves in the direction perpendicular to its axial line (axis X) and also in the direction opposite to the vertical direction, the section set between both directions is decided as the radial direction hollow. In such a way, the hollows are recognized for the turning NC data.
