1、PDM System and Mold DesignTask 1 As the president of a machine company, you may experience the following situations. Match each situation with its corresponding picture. Examining the drawings of a new mold development on computer. Presiding a meeting about innovation of data management. Inspecting

2、the workshop of the company. Discussing the warehousing issues with the warehouse worker.CBADTask 2 The following things are what you usually does for operational and technical management. Arrange them in the order of time and explain.a. Read the articles on application of PDM system in mold design.

3、b. Inspect offices and listen to mold designers advice on PDM system application.c. Observe and study the companys production and operation.d. Hold meetings to discuss what innovative measures the company may take.e. Report to the board innovative measures to be taken._Answer: a-b-c-d-e / a-c-b-d-e

4、/ c-b-a-d-e Task Task 3 3 Before reading the passage, try to answer the Before reading the passage, try to answer the questions about PDM system.questions about PDM system.a) Have you ever heard about PDM? Do you know its full name?b) Have you ever heard about any other computer-based system used in

5、 mold design?ReadingReading Product Data Management (PDM) system, a computer-based system which electronically maintains the organizational data, promises mold makers efficient data management and helps them to save time, control costs and ensure quality. The following tips will help mold makers lea

6、rn how PDM can meet their data management challenges and understand which PDM system is best for them. ReadingReading 1.Distinguish between standard and custom parts In the course of developing molds, mold makers accumulate a range of standard parts, which they purchase from suppliers, and custom pa

7、rts, which are unique and require additional work. However, they want to avoid using a custom part when a standard part will do the job. By using a PDM system, mold makers can use item numbers to distinguish between standard and custom parts, and use that information to maximize their use of more co

8、st-effective, standardized parts. ReadingReading 2. Facilitate design reuse, innovation and adaptation Reusing existing designs and adapting them for new applications is far preferable to starting every mold development project with a blank slate. A PDM system can help mold designers find existing m

9、old designs that are similar to the project at hand, which they can then easily adapt for new jobs, saving time while accelerating estimating and quoting functions.ReadingReading An integrated PDM system can automatically update BOM (bills of materials) information as mold revisions are made. With a

10、n integrated PDM system you can search for and find mold components quickly and easily using a wide range of different properties. In addition to facilitating design reuse, a PDM system encourages innovation because it allows designers to explore what-if scenarios, secure in the knowledge that they

11、can easily roll back to previous versions if a particular idea does not pan out. ReadingReading 3.Automate workflows By creating a foundation for more effective design data management, PDM systems can actually enable mold makers to optimize their development processes through the use ofautomated wor

12、k flows. Because PDM systems eliminate any questions or guesswork regarding the validity and currency of design data, mold makers can create a work flow structure around the data and improve productivity. ReadingReading In sum, no matter what type of molding a mold maker does, data management has be

13、come a necessity for competing successfully in a global market. With these tips, mold makers can not only understand how PDM can meet their data management challenges, but also determine which PDM system can help them manage mold design data most effectively. Task 3 Read the passage. Match each func

A PDM system can help mold makers improve the efficiency of data management. 2. Application of a PDM system in mold desig

16、n can help the users to ensure the quality of their products. 3. In developing molds, custom parts are usually unique and often require additional work.TTT 4. Though the output value of gas compressors was big in 2007, the percentage of the output value of the entire machinery industry decreased tha

17、t year. 5. A new mold development project like a new written book always starts with a blank plate. 6. A PDM system can help mold designers find existing mold designs that are similar to the project at hand. 7. An integrated PDM system can facilitate a new mold development.TTFF 8. Using the PDM system in mold development, you can easily obtain some new ideas. 9. A PDM system can help you to get rid of some doubts and solve some problems in your mold design process.10.To adopt a PDM system is one thing, and to improve the productivity is another thing.TTFTHANK YOU
