ABSTRACT:
The present invention aims at providing a coordinate data converting method, which is adaptable to any coordinate data in different data formats, for converting coordinate data into predetermined coordinate data, and a device thereof. A conversion parameter master table (conversion PMT) is generated in a memory with a maintenance process (process ST1) in advance. In each conversion parameter table (conversion PT) of the conversion PMT, the data of 9 items such as a code format, data format, coordinate system, unit system, offset, flow direction, PCB size, data item, and special command specification are set in correspondence with diversified coordinate data of a CAD system, an NC system, etc. A suitable conversion PT is selected with a process S1; a conversion source file of CAD data, etc., a conversion destination file according to the present invention, a board size, and a flow direction are set with a process S2; and the data of the set conversion source file is read from a memory in a record unit, converted using the conversion PT, and written to the conversion destination file of the memory with a process S3.
Since the conversion parameter master table for which the editing such as an addition, modification, deletion, etc. can be performed for the coordinate data of various systems is prepared beforehand as described above, the coordinate data of another system can be converted into the coordinate data of a local system without generating a dedicated conversion process program, thereby eliminating the need for generating a dedicated conversion process program each time coordinate data different from that of the local system is handled. As a result, both the operation efficiency of the coordinate data conversion process and user operability of a part mounting device are improved.
