As the printing machinery industry in China the first joint venture, the company mainly engaged in printing and packaging of the production equipment, in order to improve the precision, speed of appearance and development of new products, ensure that the company's leading position in the domestic market, the company introduced the firstcomputer workstations Pro / E CAD / CAM system.Been installed since the end of 1996, Pro / E software is widely used in company products, and greatly improved the speed and quality of work and achieved certain results.The following is the application of our experience of the past few years, I hope for your reference.
Selection
The basic principle of our selection:
Software system functions must meet the company designs, manufactures needs.
Software technology must be consistent with future CAD / CAM and CIMS technology trends.
Solid modeling with complex parts and surfaces design capabilities.
To have a large assembly capacity and assembly inspection capabilities.
Can generate engineering drawings in line with national standards.
Can be translated into the introduction of products CAD system resources.
Variant design and quick.
Reverse link coordinate measuring functional design.
Software company must have a good business-like conditions and market share.
Design and analysis software must have high processing and management system integration, and to ensure that data is unique.
Good service, application engineers to master the software features.
In the selection process, PTC's sales staff and engineers has been to demonstrate and explain my company, my company leaders and technical staff understand the Pro / E's role in the determination to strengthen the implementation of CAD programs, and establish the use of CADconfidence.Doing the test Pro / E functionality, PTC engineer responsible company, through the night to complete the task, and in the presentation to explain, on the spot to answer questions.Their rigorous work attitude and good professionalism make us the introduction of technical training and support after the confidence.It is for these reasons have prompted us to use Pro / E, as our implementation of the CAD design software.
The end of 1996, my company CAD / CAM system basic configuration in place, the test results, early on a large scale.
System SGI workstations were equipped with 3 sets, 2 sets of NT, 2 sets plotters and tape drives can read and write CDs and other external devices.All the equipment component two systems, that CAD systems and CAM systems.By the network connection between systems, enabling file transfer and peripheral sharing.Applied for the appropriate number of Pro / E Software License, to ensure system management and operation.
Applications
The initial period, our first task is to our partner companies - American Bo Naier Company 36 "rack-conversion and re-design.First of all, Bo Naier Internet in the United States through its two-dimensional drawings came, and then we will use of Pro / E model, a map into a drawing for our standard for manufacturing.At the same time, Bo Naier selection of software platform is also implemented.
After 12 months of hard work, we have completed all parts of the modeling and product assembly modeling and drawings, not only the product with the virtual model shown perfectly, and assembly simulation, the first increase in the drawings into three-dimensional view,expression of the parts is more intuitive and clear.
Drawings during the conversion process, we found that two-dimensional drawings of the U.S. design errors or multiple components view is inaccurate and other defects.To this end, we made a number of errors in three-dimensional drawings, Deputy marked, reached the United States put forward our views, and drawings and calculations by the United States, acknowledged the error.Also asked in detail about the application software platform.Today, the Bo Naier company also ordered a considerable number of Pro / E software platform for product design and development.
Now, our company and the cooperation of the United States Bo Naier production company, product by the Pro / E model, the use of Internet to send to my company, I just have to do is: to re-set the frame, placed into line with our standard viewadding the necessary requirements and Chinese translations, you can put into production, which greatly reduces my company's production costs, improve production efficiency, as our cooperation has opened a new shortcut.
Successful completion of this work, greatly mobilized the enthusiasm of other engineers, who have called for training; this time, PTC received tremendous support from the company, arranging a number of their engineers for training; the same time, the company also organized aapproved personnel in other school under the guidance of learning Pro / E Software.
Through training and learning from each other, most designers have mastered the modeling method, able to use Pro / E to complete their work, which fully shows the Pro / E features easy to learn and easy to use, but also to start with a full technical staffnew ways of thinking to design, develop products.
Literacy training, our main task is for the company's music products for large-scale modeling.8 months, we completed a 5 song products, thousands of parts on the model, and a complete virtual model of the product demonstrated.In this process, we found some never pay attention to the deficiencies were corrected in time.
Practical example
1.Preliminary design for product development
In the large-scale modeling, we carried out an automatic stamping machine products a significant improvement of local structure.By way of the past, a lot of competent engineers to design plans to be drawn to provide a lot of calculations for discussion, and to demonstrate, modify, and then repeatedly argument can be finalized.Today, engineers in addition to providing the necessary calculations, the remaining parts are stored in the computer and printed drawings of the virtual assembly model, for field use.
Seminar at the scene, according to the requirements of the participants will each structure, each layer assembly relationships are clear, intuitive display, but also to make modifications on the spot and the need to increase the simulation shows the relationship between part models and assembly to ensurethe revised structure of the reasonableness and accuracy.
2.Assembly instructions for the preparation of
Assembly instructions as a guiding document processes is an important job and the key process for the standardization of the operator guidance document on music products in our modeling and virtual model shows, the main job is to direct the production ofservices, in order to change the system for decades has always been written description of the assembly process, we have several engineers and Technology Branch MW1050 automatically start a new book to guide cutting production:
Components -> Department of sleeve -> machine
Components
1), having individual functions
2) in accordance with the true assembly sequence, an explosive chart display
3) The label assembly requirements and the requirements of process control
4) the self-self-test and process parameters
5) The label part of the drawing number and quantity
Department of sleeve
1) The label assembly sequence, localized to an explosion graph display
2) The label assembly requirements and the requirements of process control
3) to emphasize self-self-test and process parameters
Machine
1) The label assembly sequence
2) multi-display
3) The requirements of the whole machine assembly
4) the requirements of the whole machine assembly
After the re-establishment, the new assembly to standardize the format of the book, a clear view of the detailed technical requirements to give people a fresh feeling, by the manufacturing sector, workers at home.
3.Product design for the variant
Changes in product design, our company is to adapt to different market requirements, and the introduction of a regular job.
Simulations show that in the established on the basis of product, according to the different requirements of customers, or modify, or add, or remove various structures and components, based on parametric modeling of the Pro / E software, which enables us to more quicklyeconomical completion of the work to be carried out, and Pro / E assembly inspection powerful, but also can avoid the design of the previous variant of the collision prone to irrational structure, so changing the design of products more perfect.
With the continuous expansion of application fields, we feel that Pro / E system is very suitable for our printing machinery industry, product development and manufacturing, Pro / E based on parametric modeling approach for our modeling, mapping, processing and data transfer, reducethe possible errors, in order to establish high quality, efficient products lay the foundation, and gives us a very clear economic benefits.
