1. Background
As an important tool for the improvement of enterprise management level and information integration, ERP is a new management means combined with IT technology and management. It has been accepted and applied by more and more Chinese enterprises. Considering the long-term development of the enterprise and the demand for rational and efficient allocation and use of the enterprise's internal and external resources inside and outside the enterprise organization, our company began to carry out the ERP project in August 2013. It is expected to provide the enterprise with high quality and efficient data management platform through the implementation of the project and then transform the reliable data into information in order to explore the space for the innovation and development of enterprises. As the key of PDM and ERP system integration, BOM is the core of product structure and product configuration management. The establishment of a perfect and reasonable BOM provides detailed and visual data and graphics data for the production and management of various departments of the enterprise. The optimized storage of BOM can improve the efficiency of the system and keep the integrity and consistency of the whole system data.
2. Design Data and Sorting and Classification of Materials
The problems that many enterprises will encounter in the application of ERP systems are the establishment and maintenance of technology base data and materials, that is to say that the quality of ERP data directly determines whether or not the enterprise informatization construction and various business can develop normally or not, therefore, it is necessary to solve this problem. Starting from the reality, we first collate the products and parts in the design database, combine the ERP import, export demand and the requirements of TC to design data attributes, make TC design part attribute specification; secondly, classify the materials used in the warehouse and production site and make detailed coding rules. Through a period of combing, we have formed a clear classification and detailed coding rules the company's internal materials.
2.1 Code and Attribute Specification of Design Product
2.1.1 Code of Design Product
The product code is composed of multilevel coding. At present, it is executed according to the four-level code, of which the one-level code is identified by CP (BCP), and the two-level code is identification code identified by the English abbreviation of various products (such as: SX). The three-level code is small class coding identified by three digit identification (such as: 001), and the four-level code is flow code identified by flow number 0001 to 9999, when overflow occurs, identify according to A001-A999... Z001-Z999, in order to meet the use.
2.1.2 Product andPartAttributeSpecification
Table 1 classifies the components of products and products in detail. According to the PDM data import scheme in ERP, the properties of each component are optimized several times. Finally, the properties of parts and components that meet the requirements of ERP are planned on the TC platform and the corresponding model and attribute templates are formulated for design and use to standardize the new data and ensure quality of the data.
2.2 Classification and Coding Rules of Materials
We first analyze the ERP material management requirements of the company, formulate the specification of material naming and attributes, and standardize them from the source. Through the material attribute list, the material in the company is classified and the five-level material coding rules are formulated. One-level code is identified by English abbreviations of the large-class material identification (such as DZYHP), the two-level code is the purchase fixed mark, the three-level code is class coding identified by three numbers (such as 001), and the four-level small-class coding is identified by three numbers (e.g. 001), five-level code is flow code identified by flow number 0001 - 9999, when overflow occurs, identify according to A001-A999... Z001-Z999, in order to meet the use.
The above table gives the classification, the first level coding and the name of all the materials inside the company. The code rules and instructions are shown as follows:
For example: DZYHP.XXX.001.00.0001
DZYHP: represents large categories of materials, such as low value and easily consumed products.
XXX: purchase fixed label, such as KMA represents internal purchase, KL is traded purchase fixed logo;
001: material classification, such as taps;
001: the name of the material, such as the lengthening taps;
0001: natural number of material specifications;
According to the above materials classification and coding rules, the author completes the updating of the historical data and import the ERP through training, auditing, special communication, processing practices and the audit process as shown in Figure 1.
3. TC Design Data Can Automatically Generate BOM and Process Route and Import ERP
First of all, the project group has more standardized data through preparation; secondly, the Teamcenter design platform provides us with a good architecture and development interface to facilitate our development.
The application of Java Eclipse program development in the project
Procedure section:
/ / permission verification end

uta=newUtilApi（session）；
thread=newThread（）{

progressbarthread=newORProgressBarThread（"progress", "generating KMA material BOM..."）；

try{
progressbarthread.start（）；
session.setStatus（"please wait a minute"）；
TCComponentItemRevisionrev=bomLine.parent（）.parent（）.getItemRevision（）；//get BOMline version object bomrev=rev；
String[]strPropertyMRevForm={"k2material"，"k2chanpinn"，
"k2type_name"，"k2customer"，"k2chanpinid"}；//customer name, type name, customer number
String[]strProperty MRev Form Values；
Through the use of JavaEclipse development tools, the project group combines the actual application requirements of the company to achieve a large amount of data required by the material list of the TC data automatic generation, BOM list and process route, which not only greatly reduces the workload of the designers, but also enables BOM that needed in the production to be obtained in the shortest time by this development.
Through the above process, we can see that the data that the Designer completes through the conversion of the program into the production ERP process for production, marketing, purchasing storeroom and so on, so that the materials produced by the TC design data are interconnected with the ERP.
4. Conclusion
Through the implementation of ERP, the company has gradually formed a set of methods and processes suitable for the standard design data and material sorting of the company. At the same time, it also provides a reference method for some medium-sized and small sheet metal enterprises to standardize the design data and arrange materials. Through the application of this method and process, we successfully realized the application of history and new data on the TC platform. Through secondary development, we realized TC data generating materials, producing BOM and producing process route on ERP automatically, thus achieving the interconnection of the design data (material) ERP and improving the efficiency.
