The paper mainly studied the parametric drawing system of shaft based on feature. Firstly, the shaft was classified, and its characteristic was analyzed. Then, the special menu and image block menu of the system were designed in AutoCAD. And a friendly-interface parametric drawing system of shaft was built with geometry sculpts technology, object-oriented technology and parametric design technology, based on the platform of AutoCAD, with the development tool of Object ARX. It implemented the drawing of hardware working drawing of shaft according to the selected proportion, and improved the efficiency of the shaft design.Overview of shaftShaft is one of the main parts of machinery, depending on the axis shape; shaft can be divided into two categories: direct axis and crank shaft. According to the different load of the nature, direct axis can be divided into three types: spindle, drive shaft and the shaft. According to different shape, direct axis can be divided into two kinds: optical axis and stepped shaft. Optical axis has the following characteristics: simple shape, easy processing, less stress concentration source, optical axis is mainly used for drive shaft; Stepped shaft, in contrast to the optical axis. It is often used in the shaft. The classification of the shaft can be clearly said to use figure 1. In addition, there are some special shaft, such as the camshaft and wire soft shaft, etc.Fig. 1 Classification of the shaftOn the basis of the characteristics, the shaft information model can be considered. Usually a mechanical parts contains numerous features, shape features are the most important characteristics of these, which is the carrier of other information. We can decompose research the shape feature and think that some auxiliary features and the main features combined shape feature of axis, the main characteristics of the spatial position is adjacency relations; Auxiliary features is attached to a primary, auxiliary features can be attached to the main outline of the surface or end[1].Combining with the actual situation of this system, we analyze the features of commonly used straight shaft parts; we obtained the shape of the feature classification results as shown in table1.Table 1 Straight shaft parts classification of shape feature

This paper studies a new approach to developing AutoCAD in MFC with ActiveX Automation technology. It successfully solved the problem that development visions of Object ARX are not correspondent. It analyzed the application of dispatch interface in IDispatch technology and VARIANT type data in depth. In addition, it gave out practical cases in which this approach is used and particularly discussed the method for using blocks and searching through diagram objects. This designing realized the automatic designing of engineering drawing and automatic extracting of information.

The medium-depth blasting design of underground mining needs to do a lot of data- processing of geological survey and graphics rendering. It is repetitive and tedious. This paper introduces a Medium-depth hole blasting design CAD system (MHBD) based on Object/ARX. However, the system of non-pillar sublevel caving can decrease the labor intensity, reduce design time and improve labor efficiency.

With the good ecological functions, the raw-soil structures attract attention of the people all over the world recently. According to surveys, more than 30 million farmers in China still choose to build their house using raw-soil. Since the advent of CAD/CAE techology, it became easier for engineers to design better buildings. However, for lack of adequate research on raw-soil structure, existing domestic and oversea softwares are incapable of solving the detailing work of this structure. In this paper, characteristics of the raw-soil structure and software function requirements are analyzed; the framework, data structure kernel are designed for a specialized detailing CAD information system based on BIM (Bulidgin Information Modeling). Finally the raw-soil software is developed with Object ARX technology and AutoCAD graphics platform, and an example is introduced to show the main functions.

With the wide applications to the fields of petrochemical, military, metallurgy and mining, pumps have to subject to more and more serious working conditions. In order to avoid disaster damage caused by failure of the shaft, it is quite necessary to calculate and examine the shaft strength. A kind of two-dimensional software was developed using the secondary development tool of Object ARX, to achieve the shaft strength calculation accurately and conveniently, and which avoided the disadvantage of the traditional method. The calculation methods of shaft critical rotation speed and the static bending displacement were proposed. Theoretical analysis and calculations on the strength, rigidity, vibration and other aspects of pump shaft were conducted under shut-off condition and best efficiency point using ANSYS APDL software of static, dynamic and transient modal analysis method. The quality of pump shaft was analyzed through the comparisons of numerical results, and further more the accuracy of two-dimensional development software was validated. The practical application indicates that the shaft parts strength calculation software can improve the quality and efficiency, reduce wastage during the pump shaft design. These research achievements will also have a great application prospect.

Currently, manual inspection and off-line inspection play an important role in the inspection methods of machining process, which severely restricts the development of inspecting automation. In the paper, automatic programming system for machining center on-line inspection was developed by secondary development kit object ARX of AutoCAD. Inspecting datum was obtained, inspecting process planning was laid up and inspecting program was made automatically. The inspection can be applied to automatic workpiece setting up, on-line inspection of workpiece, data processing, quality analysis and compensation of machined workpiece errors, which led to increase precision, production efficiency and quality and reduced the rate of rejection and tool damage.

In modern manufacturing, it is urgent to require integrating manufacturing and inspection because manual inspection and off-line inspection severely restricts the development of inspecting automation. In the paper, automatic programming system based on solid driven technology for machining center on-line inspection has been developed by secondary development kit object ARX of CAD. Inspection feature datum and information were gotten by ARX tool in CAD stage, and then inspecting program can be automatically made up through inspecting process planning. On-line inspection automatic programming system based on solid driven technology has been applied in SSK-U6035 machining center. The application result shows that the programming system is simple and effective, which has realized integration of manufacturing and inspection more efficiently, increased precision, production efficiency and reduced the rate of rejection and tool damage.
