picture into a mathematical model and Mores it in the data base for later use.
Mathematical modelling is considered to be most important feature оf а CADD system. This feature can produce a model of a structure for stress analysis, or it can provide input for automated drafting to produce engineering drawings. CADD systems can be ten times faster than manual drafting.
If CAD/CAM systems are linked, the mathematical model can also be used to create numerical control (NC) tapes for fabricating the part.
The oldest CAM technology is numerical control, the technique of controlling a machine tool with pre-recorded, coded information to fabricate a part. Today, engineers are trying to integrate the technologies of CAD, NC and IR (industrial robots).

CAD/CAM SYSTEM AND FMS
It should be stressed that now it has become necessary to direсd efforts towards the more flexible response of production flow from planning, designing, production engineering to manufacturing.
To solve this problem the Computer-Aided Design/Compuer-Aided Manufacturing (CAD/CAM) and the Flexible Manufacturing System have been and put into practical use, the CAD/LAM system to integrate data for the design of production processes and the FMS to act as a production system.
As is known, the development of these systems has become possible due to increasing application of electronics such as the high speed and compact size of computers which advanced rapidly in recent years.
Previously the FMS and the CAD/CAM system progressed from different directions. This is mostly because the CAD/CAM systems developed from the technological side, i.e. with emphasis laid on design, while the FMS developed from the manufacturing side, i.e. with emphasis put on machining.
In point of fact, however, these two systems are highly corrected with each other in basic areas. In other words, the techno¬logical integration of the CAD/CAM system and the FMS has be¬come ultimately necessary.
For example, the FMS is a system which aims to unman vari- |
ous types of machining operations, inspection and transferring per
plant from the material to the final stages, giving rise to improving productivity of low production volumes in a variety of sizes.
In the design of the FMS, the main objectives are the arrangement of production equipment, machines, computers, warehouses and transfer units.
A definite system of processing a lot of data on plans and design had to be established.
The origin of the CAD/CAM system is generally said to be the interactive computer graphic system. The application of this new computer technology particularly to the design area, i.e. the CAD system, was put into practical use mainly among aircraft builders.
Although CAD/CAM systems were large-scale, based on oversized computers, a small-scale turnkey system was later developed which utilized a minicomputer as a host. This turnkey system rapidly expanded and found its application first in the design of circuits and later machines for diemaking and sheetmetal processing.
The ultimate aim of CAD/CAM systems currently available is common in the design of equipment, including the in-house developed systems and the integration of product design, production design and production control.
If the integration of design and production data is advanced and the combination of the CAD/CAM systems and the FMS which is the desirable production form as a system to turn out products in low production runs in a variety of sizes, is also advanced, automation can be accomplished at a plant level and unmanned operation-oriented FA can be achieved.
In order to apply the CAD/CAM systems on a full scale to machining operations and also forward the application of FA through the integration with the FMS, the most important aim is to raise the level of automation in processing which is connected with machining and production technologies.
For this purpose the advanced FMS, a production system, has been developed to integrate the CAD/CAM systems and the FMS. In fact, the advanced FMS integrates the conventional FMS and the "data flow" such as design and production engineering data.
Thus a FMS consists of two machining centres and one CNC cylindrical grinding machine connected by an unmanned carrier and a super-minicomputer.
The features of the system are as follows:
The task of CAD function is to perform designs necessary in the production stage such as jig and fixture design, cutting tool design, machining and installation drawing preparation. |
