外企的十大UGNX作图原则

1.  Clear and Clean Assembly Structure:The assembly structure in TCEng and Master Engineering Plan are always corresponding; Each work pack owner is responsible to keep the subassembly clean.

2.   No suppressed Features when saving parts: Suppressed features will lead to corrupt 3D models. Always keep in mind that another team member has to understand the feature tree of a NX model;

3.    Work on TCEng not native: The NX data is always available for the whole team;

4.  Features well organized by Layer settings: Setting layers helps to keep the overview within a solid. Layer categories are defined within NX seedpart for Siemens BT.

5.  Versions are built up by creating revisions: Different design variant of the same parts will be created by using revisions within TCEng;

6.  Set the right Reference Sets: Reference sets define what will be displayed on a upper level in the assembly structure; It is a must to set the 3D-Model which will be displayed in the assembly or on the drawing on reference set called “solid”.

7.  Use Speaking 7 Billion Numbering System: Part numbers used within products are created with speaking 7 billion numbers. For other items like used in test equipment use nonspeaking 8 billion numbers. Do not use PEK-numbers.

8.  Work Tracking: Workpack owners always track running issues regarding parts within a work tracking list.

9.  Dimension on drawings MUST be assotiative: It is forbidden to change dimension on drawing manually by annotation editor.

10.    Follow design rules defined in CHECKDRAW: Checkdraw is available from your superuser.

1. Clear and Clean Assembly Structure:The assembly structure in TCEng and Master Engineering Plan are always corresponding; Each work pack owner is responsible to keep the subassembly clean.

明确和清晰的装配结构:在Teamcenter Engineering里的装配结构要和主工程计划里的始终一致,每个工作任务的所有者负责保持装配的清晰。

这个是与工作环境有关系,研发过程中除了在Teamcenter Engineering里维护了装配结构外,还需要在本地项目的文档里建立装配结构,这一条的意思就是要保持二者的一致。

2.No suppressed Features when saving parts: Suppressed features will lead to corrupt 3D models. Always keep in mind that another team member has to understand the feature tree of a NX model;

保存零件时不准有抑制的特征:抑制的特征会导致3D模型混乱。始终记住另一个团队的成员需要理解NX模型的特征树。

如果在建模时有抑制的特征,会导致其他人看图时不明白这个特征是要还是不要,不利于对模型的理解,如果这个特征不需要了,就直接删除就可以了。

3.Work on TCEng not native: The NX data is always available for the whole team;

基于Teamcenter Engineering工作而不是本地工作;这样整个团队都能获取NX数据。

这也是PDM或者PLM软件的好处,便于数据的共享。

4. Features well organized by Layer settings: Setting layers helps to keep the overview within a solid. Layer categories are defined within NX seedpart for Siemens BT.

特征通过层设置进行组织:层设置便于通过实体来总揽,通过定义NX种子文件设置适用于整个集团的层分类。
在该外企里定义了自己的企业标准,每一类层包含哪些,都有具体的含义,当工程师建完模型后,要进行特征组织,把相应的特征放到相应的层里。这样可以通过调整层的显示,让模型只显示实体,而不显示草图、基准特征等,便于模型的理解。

5. Versions are built up by creating revisions: Different design variant of the same parts will be created by using revisions within TCEng;

通过在Teamcenter Engineering里建立修订版来控制版本:使用Teamcenter Engineering里的修订版来建立同类零件的不同设计想法。

6. Set the right Reference Sets: Reference sets define what will be displayed on a upper level in the assembly structure; It is a must to set the 3D-Model which will be displayed in the assembly or on the drawing on reference set called “solid”.

设置正确的引用集:引用集定义了在装配结构的上一层中零件的显示方式。在装配和工程图上显示的3D模型必须设置为"Solid"引用集。

以下是NX自带的引用集,该公司设置了自己的引用集标准,并且要求设置为"Solid",其实现原理跟第4条一致

7. Use Speaking 7 Billion Numbering System: Part numbers used within products are created with speaking 7 billion numbers. For other items like used in test equipment use nonspeaking 8 billion numbers. Do not use PEK-numbers.

这是企业编码的要求,只解释下 speaking 和nonspeaking 的区别,speaking的编码是结构化的编码,每一位表示具体的含义,non的编码则是一个大流水,没有具体的含义。

这是在使用NX/Teamcenter时的要求

8. Work Tracking: Workpack owners always track running issues regarding parts within a work tracking list.

工作跟踪:工作任务的所有者始终在工作跟踪列表里跟踪零件存在的问题。

这是企业研发流程的需要,Teamcenter只存了3D模型和二维工程图,零件中存在的问题通过项目管理的work tracking list来进行跟踪,并要求工程师保持二者的一致。

9. Dimension on drawings MUST be assotiative: It is forbidden to change dimension on drawing manually by annotation editor.

工程图上的尺寸标注必须关联:禁止通过“注释”来修改工程图上的尺寸标注。

这样可以保持3D模型和工程图的一致,当3D模型做了修改时,工程图的数据会自动更新。同时也便于其他人理解工程图。

10. Follow design rules defined in CHECKDRAW: Checkdraw is available from your superuser.

遵守CHECKDRAW里的设计要求:可以从superuser那获取CHECKDRAW文档。

CHECKDRAW是一个企业规范,定义了详细的作图原则,图纸模板,以及NX/Teamcenter的操作规范。

superuser是部门的NX/Teamcenter负责人,因为superuser更了解业务。在工程师有问题的时候,先向superuser反应,如果superuser解决不了,再由superuser向公司的admin反应,admin解决不了会向总部的支持团队反应,总部的支持团队也解决不了的时候,再向软件的供应商反应。
