ABSTRACT:
A numerical control information generating apparatus generates numerical control information within a short period of time, since it extracts a machining portion from the input blank shape and the input machining shape and automatically divides the machining portion into first and second machining portions at the right point. The present apparatus controls a numerical control lathe with two headstocks, and includes: a divider for extracting a machining portion from an input blank shape as well as an input machining shape and for dividing the machining portion into an outer diameter machining portion which is to be machined by an outer diameter machining and an inner diameter machining portion which is to be machined by an inner diameter machining a determinator for determining divisional candidate positions which are positional candidates for respectively dividing the outer and inner diameter machining portions into a first machining portion to be machined by a first head stock and a second machining portion to be machined by a second headstock, and an automatic divider for selecting a divisional position from among the divisional candidate positions wherein a ratio of a cutting area of the first machining portion with respect to a cutting area of the second machining portion is selected to be closest to an output ratio of an output of a spindle motor of the first headstock with respect to an output of the spindle motor of the second headstock and for automatically respectively dividing the outer and inner diameter machining portions into the first machining portion and the second machining portion according to the divisional position.
