A numerical control information generating apparatus for automatically determining machining modes of a numerical control machining device based on data denoting a shape of a starting material and a shape of a finished part, comprising:
- means for determining a machining area by comparing the shape of the starting material and the shape of the finished part;
- means for dividing the machining area into a forward end surface machining area which can be cut by a forward end surface machining tool, a reverse end surface machining area which can be cut by a reverse end surface machining tool, a forward longitudinal machining area which can be cut by a forward longitudinal machining tool, and a reverse longitudinal machining area which can be cut by a reverse longitudinal machining tool;
- and
- means for determining the machining modes for each of the forward end surface, reverse end surface, forward longitudinal and reverse longitudinal machining areas.
A method for determining machining modes of a numerical control machining device based on data denoting a shape of a starting material and a shape of a finished part, comprising the steps of:
- determining a machining area by comparing the shapes of the starting material and the finished part;
- dividing the thus determined machining area into a forward end surface machining area which can be cut by a forward end surface machining tool, a reverse end surface machining area which can be cut by a reverse end surface machining tool, a forward longitudinal machining area which can be cut by a forward longitudinal machining tool, and a reverse longitudinal machining area which can be cut by a reverse longitudinal machining tool;
- and
- determining the machining modes for each of the machining areas obtained in said dividing step.
