The purpose of this chapter: web version tolerance analysis software written mission statement, making clear design task.
Right when he wrote his.
1. The purpose of making tolerance analysis software
1.1 to engineer a good design habits
Tolerance Analysis thing to do is not absolute, but it will do a lot better.
There is a tolerance analysis software, you can develop a good habit.
1.2 improve the mechanical design environment, reduce the difficulty of designing methods used
I let a mechanical engineer working environment a little better, I think what tools, on a page can have readily available.
I know there are issues of data security and the like, but network engineers to solve such problems, when the convenience of the desktop web client software can not be replaced, especially when it was very young.
In short, I want to do a set of small industrial software, database can be common, this is the first.
1.3 to do a complete analysis of tolerance aid
This is also a good habit!
A product to do a complete tolerance analysis, too much effort for structural engineers.
Author did a small water pump complete tolerance analysis, calculated at 130 times or more.
But only focus on tolerance analysis, it is difficult to improve the quality of products produced. How many will feel a little structural engineer.
So I hope to make tolerance analysis software like a Web page, complete with tolerance analysis written tutorials, can reduce the workload of engineers to speed up the progress of the project, but at the same time can improve the quality of product design.
2. Status
2.1 lack of Software Industry
Domestic software industry status quo mechanical design scarce, we do not pay attention.
Large industrial software, such as 3d mapping software, are foreign, such as CATIA, proe, SolidWorks, UG and so on; 2d graphics, such as caxa but added the country, but has been somewhat behind the times.
Small industrial software are scarce, several slightly complex operation and requires a fee.
The tolerance analysis software are all desktop software, and ninety percent is required fee, the use of poor reflect, not better form.
2.2 intellect and consciousness
Do not do these software industry software, mechanical design and not because it would not make money.
Do not do these mechanical design software industry, because not aware of its role and do not write their own software.
2.3 Status of lazy fall
Details now tell tolerance analysis, other design methods are also similar.
Domestic structural design engineer in the 3d era already less emphasis on tolerance analysis of this design approach.
One is because it will push the slow progress of the project;
Second, because of acute tolerance analysis is difficult to produce a significant effect (particularly incomplete tolerance analysis under);
Third, the domestic atmosphere, a lot of responsibility is limited to engineers to solve problems after an error, it can be a good way to prevent problems in advance - Tolerance analysis, but something is broken engineers of the future.
Therefore, the reliability level car below the level of mechanical industries, such as home appliances, consumer electronics, small-scale test equipment, with few means of analysis of tolerance, of more or less asked peers, know something.
The vehicle reliability rating level or the same level as some of the medical industry, and more focus only tolerance analysis. If the appeal of participating in product design, done in 20 130, it has been considered important to complete tolerance analysis. But it is difficult for good early in the product, the last mostly filtered by detecting substandard products.
Instant success, and had quick success, the machinery industry is now considered a phenomenon.
Many mechanical engineers say do not have access tolerance analysis, the reason is probably the most honest he did not go to good use, doing 100 or more tolerance analysis, it is useful to know. But there is no software assistance, really hard.
3. some effort to change the status quo
Thoughts articles: 8) Imagine a mechanical engineer on the Promotion of the Status of structure
Already written too much. This right when it wrote its own.
These small software industry do indeed make the wheels. Or training wheels.
4. The software interface requirements
I met tolerances software and tables, this form to give people the best experience. (Original form by NOK * A company)
But this is just a form for a tolerance analysis.
If it is a tolerance analysis for the entire product, you need a summary table below.
And, two tables of data must be linked to do the job. This is on an excel spreadsheet lack.
And I want to support a variety of analysis functions, such as micro-channel public interface of the same number.
Public micro-channel number and the number of blog site's functionality and interface, can really be applied directly on the software industry.
The authors also know that many of these analysis functions have a direct plug-in module. For the software industry can do for them on the page is very useful.
5. Web page software functional requirements
Write this section is to get hold of the software ready to do later, probably to write their own, or may be directly handed over to someone else. To be considered a just,
5.1 Login
Reference numbers refer to the public micro-channel interface.
5.2 CRUD an entire project
Tolerance analysis is to divide the project, rather than a single tolerance, the authors hope to CRUD tolerance of the entire project.
As shown below.
5.3 Adding a whole project, there is part tolerance input table
This chapter represents the tolerance existing parts.
// It would also have a serial number.
建立一整个项目后，有一个页面是这个零件公差输入表界面。
这个界面的功能有：
1）增删改查零件。
2）增删改查零件下的尺寸和公差。
后面的具体公差分析页面的输入数据就直接从这种表中调用，数据的联动和数据库的通用。
3）分析：零件的尺寸公差在后面公差分析中的使用数目。
4）分析：柱状图显示结果（其他的也行）
5）若是重要的分析中的尺寸，可以显示红色（这个先不加）
5.4 添加一整个项目后，就有公差分析目标汇总表
这一章代表了一个项目公差分析的要求
建立一整个项目后，有一个页面是这个公差分析目标汇总表界面。
这个界面的功能有：
1）增删改查公差分析目标。
2）分析功能：暂时未定。
后面的具体公差分析页面的输入数据就直接从这种表中调用，数据的联动和数据库的通用。
5.3 生成具体公差分析的界面
5.3.1 界面
其实这章界面就挺好。
界面的模块可以调换顺序一下，避免专利打架。后期也可以追加调整。
界面上的数据都取决于上两张表格，这就是作者常说的数据的联动。
界面上公差分析公式后期可以撸下来
5.3.2 界面的个数
具体公差分析的界面个数和《公差分析目标汇总表》中添加的公差分析个数有关，添加一个公差分析的目标尺寸，就自动生成一个公差分析界面。删除一个，就删除一个界面。
这才是作者最想要的。
5.3.3 界面的提示
当公差分析不合格时候，公差分析汇总表和公差分析具体见面会有提示，如显示红色等。
6.本网页版软件优点
1）不需要公差分析去链接必要的3d软件；
2）网页端软件，系统负载小，数据库在服务器，查询方便；
3）贴合实际使用情况，可以做几个重要的公差分析，也可以做完整的。
4）公差分析是机械设计最常用的工具，适用方便。
7.优化与可能
后期希望零件名称以及尺寸能直接从BOM表中的数据库导入，而不需要一次次的输入。
