Development of system of CAD of modular machine tool and research

1 use technology of CAD of modular machine tool imperative
Modular machine tool is to use the special machine tool that the special part that the current part that designs by seriation, standardization and the appearance that press workpiece and treatment craft requirement design comprises, belong to one-time design, one-time those who make is odd a manufacturing product. Accordingly, design amount is large, design work is intricate. In the market economy with current intense competition, the user is advanced to the technology of the machine tool reliability of gender, quality and the cycle that offer money asks very tall, and assuring this key of a lot of element is a design. The sort of backward handiwork designed a method to already cannot satisfy the requirement of products plan in the past, use CAD technology, throw drawing board, already made the trend of current technology revolution, imperative.
CAD of 2 modular machine tool uses the current situation
The research of technology of CAD of foreign modular machine tool begins earlier. At the beginning of 70 time, developed country of a few industry begins to consider in respect of CAD of much axle box above all. Since entering 90 age especially, as the development of computer technology, seesaw pattern plot and the development that the database runs a system to wait and application, make technology of CAD of modular machine tool increasingly practical and scope of application expands ceaselessly, the developed country used CAD technology generally already in design of modular machine tool. Current, to CAD/CAM compositive system develops.
In recent years, be opposite according to us manufacturer of a few main machine tools of American (the company such as BURGMAST, KINGSBURY, INGERSOLL LAMB, CINCINNATI, MILACRON, CROSS) understanding, its CAD technology already got applied generally. Among them the most conspicuous is the environment of soft, hardware that INGERSOLL company has workstation of CAD of 50 seesaw pattern to comprise, made show actually almost 100 percent CAD is changed.
The knowledge that home uses CAD to design of modular machine tool is earlier also. At the beginning of 70 time, institute of Dalian modular machine tool works with respect to the research that began this side. The country labelled CAD of modular machine tool 1978 mechanical industry priority discipline, enjoin institute of institute of modular machine tool of Shanghai traffic university, Dalian, mechanical ministry automation is responsible, the unit such as academy of mechanical and electrical products of college of Dalian grain industry, Tsinghua university, Beijing industry university, Shanghai attends, undertook study to CAD of bore modular machine tool, what unveiled technology of CAD of our country modular machine tool from now on is prelusive. Through effort of more than 10 years, obtained preliminary positive result.
But, system of CAD of modular machine tool is in VAX Ⅱ - 750 with the development on Micro VAX Ⅱ , hardware investment is large, do not popularize application easily. Accept the restriction that hardware condition reachs software environment at that time, software suitable scope is narrow, the user uses inconvenience.
