Abstract
An automatic programming system is incorporated in a numerical controller which controls the operation of a machine tool connected thereto in accordance with a numerical control program. The programming system is designed to automatically program the numerical control program based upon machining information which is manually input by means of a data input device in an interactive mode for defining machinings to be effected on a workpiece. The programming apparatus includes means for automatically determining the machining order of a plurality of machinings on a workpiece in such a manner that any machining needing a higher accuracy is carried out later than any other machining needing a lower accuracy.
Claims4
An automatic programming system for automatically programming a numerical control program used in successively machining a plurality of machining portions on a workpiece, based upon machining information input for said machining portions, said programming system comprising:
- data input means for inputting, in addition to said machining information, accuracy data assigned to at least one machining portion which requires a higher machining accuracy than others of said machining portions;
- data storage means for storing said machining information and said accuracy data input by said data input means;
- machining order determination means for determining the machining order of said machining portions so that any machining portion needing a higher machining accuracy is machined later than any other machining portion needing a lower machining accuracy, by reference to said accuracy data stored in the data storage means;
- and
- program preparation means for preparing a numerical control program used in successively machining said workpiece portions in said machining order determined by said order determination means, based on said machining information stored in the data storage means.
