Consumer product ( Samsung Camera )

Samsung Camera had been using 2-Dimentional CAD system  by late 90s. but we recommended 3D CAD system for improving design productivity remarkably in 1995.

Before we made the decision, we did bench mark test serveral times in terms of cost-performance. because of specific camera design,we decided to adopt ProE with parametric technology after a number of prototype testing. 

 

Industrial device ( Samsung Chip Mounter )

Samsung chip mounter ( SVP series ) was
designed with AutoCAD R12 by 1998. but
designers have faced serious problem
because assembly is too complicated to do with AutoCAD. so we are in progress doing 3D prototype by ProEngineer.
Chip mounter system consist of a large number of components which means we are required to maintain good hard ware performance. despite high cost of hardware  

 

Samsung FA ( Factory Automation )

 Samsung delivers factory automation systems to the customers such as pallatizer, robot and so on
we adopt 3D cad system as design tool reducing design  time and time-to-marketing and improving product quality
Right example represent 3D modeling

Case study of 3D CAD System in Samsung aerospace Co.ltd

     Overview

It has been known to have a kinds of limitations to design products early step in conceptual stage compare with 3-Dimentaional CAD system in terms of implementing so-called CE( Concurrent Engineering ) concept which means 2-dimentional CAD is just nothing more than a way of communication by designer or drafter without leaving production data such as NC Data,measurement data
It has been reported that 2D-drawing itself might cause mis communication between people involved in engineering process. Vice versa, when it comes to 3D CAD system, with 3D CAD system, from early times on production cycle,Nowadays It's desirable to consider all factors which might affect all engineering process such as assembling,Die design,jig & fictures, so on. Serious problem would be arosed without removing possible problems this is The earlier step the problem found in,the less it cost ,,

 From above point of view, we realized that 2D-CAD couldn't have possible solution any more just with 2-dimentional CAD systems In order to overcome this limitation, we had tried to look for "Concurrent engineering" concept based on 3D-CAD system Which means it's possible for All engineer associated with a certain engineering process to share 3D CAD Model Data, mostly singe data type, allowing them to find all potential problems. When it comes to 3D CAD system. We expected that it's all possible for all related data to be used from 3d geometric Data,once created in production Design state,could be used next process like Die design, NC data generation and so on. We think that it's very important in terms of intergrated information,removing information losses in all CAD related process or redundancy and also we found out CE process can shorten overall production lead time by overlapping process to process. therefore 3D CAD system is enabling technology to achieve this goal. 

Realizing Limitation with 2D CAD system.
Frequent communication error based on un-intergrated process
Necessity of innovation in design and technology

  Problem with 3D CAD system
     loosening lead time due to serial process
     Lack of data consistency between every work group
     Too much cost due to long lead time,bad quality
     Loading too much work on latter process
