The Development And Application Of Two-dimensional Casting Steel Processing CAD System Based On JPG File

Casting is one of the most important basic industries in our country which plays animportant role in the development of national economy. Casting process CAD systememerged under this atmosphere. Casting process CAD system helps process designersdetermine the casting solution and draw casting process. At present, most of the castingprocess CAD systems are secondary development based on AutoCAD platform with along development cycle. The use of AutoCAD is limited by its version. Once upgraded,casting process CAD system based on the original version has to do the upgrade workaccordingly. At the same time, due to the confidential requirements, communicationbetween most foundry enterprises are based on paper or JPG image file, it takes them a lotof time to diagram the parts before mapping the foundry molding drawing whichobviously reduces the efficiency of casting process design.This subject aims to develop a two-dimensional casting steel process CAD systembased on JPG file. By importing the JPG file of design drawings into casting processingCAD system, we can directly add parting surface, machining allowance, sand core, riser,gating system and chiller on file. Through which the efficiency of process design will begreatly improved. With Microsoft VS2008as its development tools and key technologiessuch as ODBC database development and interactive graphics, this topic has completed aset of casting steel processing CAD system which is relatively perfect function.Through this system the design and drawing of casting process can be facilitated andaccelerated. Process designer can complete the design and drawing of parting surface,machining allowance, draft angle, core, pouring system, riser and various kinds of processsymbols according to the process design flow. Relevant data involve in the design processcan be directly obtained from the Access database. Above all, production efficiency isgreatly improved.
