BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an automatic programming method for effectively and accurately creating NC data for combined machining.
BACKGROUND ART
It is known to create NC data (NC program) for operating a combined machining apparatus adapted to perform plural kinds of machining, by the use of automatic programming apparatuses. Since a conventional programming apparatus is a single purpose device having a function of creating NC data for one particular machining alone, plural kinds of programming apparatuses are employed for creating NC data for combined machining.
For example, in the case of creating NC data for combined machining for carrying out turning and milling together, part programs respectively relating to turning and milling are created beforehand. Then, NC data for turning is created based on the part program for turning by the use of a programming apparatus, whereas NC data for milling is created based on the part program for milling by means of another programming apparatus. Further, NC data for turning and milling are so edited as to create NC data for the combined machining.
According to the above conventional method, it requires a great deal of time and labor to create the NC data for combined machining, and an error is likely to occur in an editing operation of NC data such that input sequence of NC data is mistaken.
DISCLOSURE OF THE INVENTION
The object of the present invention is to provide an automatic programming method for creating NC data for combined machining effectively and accurately.
In order to achieve the above object, the present invention comprises the steps of: (a) creating a part program for combined machining which includes first and second part programs respectively relating to first and second kinds of machining; (b) providing a group of translating means which includes first and second translating means for translating the first and second part programs into first and second NC data respectively relating to the first and second kinds of machining; (c) reading the part program for combined machining one block by one block, and automatically determining a kind of the part program of the block thus read; and (d) automatically translating the part program of the read block in step (c) by use of that translating means whose kind corresponds to the result the determination in step (c), whereby NC data for combined machining is automatically and continuously created on the basis of the part program for combined machining.
As explained above, according to the present invention, a part program for combined machining, including the first and second part programs respectively relating to the first and second kinds of machining, is read one block by one block, a kind of the read part program is automatically determined, and automatic translation to NC data is effected by the use of that translating means whose kind corresponds to the kind of the read part program, among the group of translating means including the first and second translating means for translating the first and second part programs into first and second NC data respectively relating to the first and second kinds of machining. Thus, NC data for the combined machining can be automatically and continuously created on the basis of the part program for the combined machining. Accordingly, it is unnecessary to create various part programs, which cooperate to form the part program for the combined machining, separately for kinds of these part programs. This permits efficient creation of the part programs. Moreover, an operation of editing various NC data, obtained by translating the various part programs into NC data for the combined machining, is unnecessary, so that errors attributable to the editing operation never occur. As a result, it is possible to positively and rapidly create the NC data for the combined machining for conducting various types of machining in a desired sequence.
