Lever kind CAPP of spare parts machining

The ADS in 0 above version and AutoCADSQL and its augment ASE occurrence that develops interface, with respect to more high grade and quick implementation CAPP offerred good technical condition. 1.

The principle of 1 system and form 1.

Personnel of technology of complete imitate project designs system of 1 job principle artificially the method of connecting rod process, in the process that has automatic or alternant design in the working procedure card to some line working procedure, complete the design of all craft file that concerns to it. Its flow is shown 1 times like the graph. 1.

2 total constructions this system is comprised by database, library and graphical library, the data between each library is OK and dynamic join, if pursue,2 are shown. The processing of technical data of 2 connecting rod 2.

The treatment craft of the affirmatory connecting rod of 1 standard procedure has very strong regularity, if the connecting rod specific and identical structure presses model to return,be gens, criterion their treatment craft line is same, it is technical data and working procedure dimension differ only. After the model that inputs crankshaft when the user accordingly, the system can call corresponding craft course, tool and device in the database according to this one parameter 3 databases, call corresponding primitive process chart to get stuck from inside graphical library. The warehouse of comprehensive technical data of technical data of workshop of an overall record still was built in the system, get stuck in working procedure with convenient user browse in the design, undertake at the same time supplementary and revise. 2.

Dimension of 2 working procedure consults surely really the slide of connecting rod, dimension of ordinal in the dialog box input and public errand, can get final spare parts measure systematically. According to principle of retrorse process designing, through calling the corresponding surplus in database of working procedure dimension and common difference, computation gives the treatment dimension of each working procedure and common difference, tag in process chart corresponding locally. The data in library of dimension of working procedure conversion can be mixed according to the type of connecting rod size, decide by spot technology division, through database management at the same time subsystem is returned can be revised conveniently or increase data. The trends of 3 technical data joins 3.

1 standard working procedure gets stuck build the working procedure that establishs a standard according to the appearance of connecting rod in Auto CAD to block graphical library, the standard working procedure of each type is file of a graph, the graph layer that the card of each working procedure takes up one is serial number with working procedure date, process chart did not tag dimension. After technical data joins for exterior database trends through ASE, fill in to go up in working procedure card, above all initialization ASE, appoint database of corresponding standard tool, equipment respectively, search a tool according to working procedure date, the data of measure and equipment, the corresponding position in card joins for entity with horizontal division line this one outside data, draw up by command of data to load. Draw up with this kind of method the technical data of all graph layer, save file to disk the form of the to in an attempt to when exiting saves working procedure card and the dynamic join with exterior database. 3.

The modification that 2 working procedure block is in the procedure design process of connecting rod, should undertake probably a few revise. Revise to technical data can command through ASE, want modification data with mouse collect, open exterior database, burden has to data again after revising, such databases and working procedure card get be correctioned likewise. If want to choose the data that does not have in standard library, can enter data to browse module through menu or command, appropriate tool and equipment are searched in the library of comprehensive technical data of the workshop, pass the additions and deletions of database of pair of standard tools, equipment, data to load, of the technical data that finish alter. The modification of process chart can use the operation order of Auto CAD directly, and after the modification of working procedure dimension and public errand also can pass the data of library of dimension of join of change working procedure, new moving program is obtained. The technology of ASE database interface that 4 conclusion use AutoCAD and technology of ADS process designing can realize the dynamic join of all sorts of data in design of connecting rod procedure, the kind that ties interactively through be being mixed automatically, can the design process of procedure of connecting rod of modular personification labour and method. The system shortened greatly not only the design is periodic, reduced labor intensity, and the quality that still can improve craft file. Further progress direction of the system is the design characteristic that the technology of SQL database interface in using AutoCAD replaces general ASE to command combinative crankshaft procedure. Raise systematic adaptability and automation rate further. CNC Milling
