ABSTRACT

Currently, most of the equipments that have been invested in mechanical engineering in

Viet Nam are not synchronized. There are many NC machines and CNC machines that

have old controllers which can not link computers with integrated CAD/CAM system.

Therefore, it may not able to apply CAD/CAM/CNC technology in such systems. This

article presents a model and research results for integrating CAD/CAM system with CNC

machines using a Fanuc controller and for deploying CAD/CAM/CNC technology

applications in training and technology transfer at Thai Nguyen University of Technology.

* 1. INTRODUCTION

Currently, CAD/CAM technology applications

are becoming common in manufacturing and

process engineering in Vietnam. For training

and transfering this technology, Thai Nguyen

University of Technology has invested in

equipments such as: CAD/CAM design

laboratory, machine center VMC-85S,

Coordinates Measure Machines (CMM) -

C544, Rapid prototyping machine - 3DP,

Computer Integrated Manufacturing -

OpenCIM... However, the machine center

VMC-85S is not able to be connected with the

CAD/CAM system, because the machine

does not have a DNC function and signal

transmission cable. As well, no transmission

software is installed in the parameter

functions of the machine.

To widen the ability of the VMC-85S in

machining 3D surface, to improve the training

process and the transfer of technology at Thai

Nguyen University of Technology, the VMC￾85S machine should be connected with the

CAD/CAM system.

2.1. Methods to connect CNC machine

In order to connect the CNC machine, the NC

code can be delivered from one or more

computers. The process will then compile the

content of the files into the NC code; this code

provides commands for the operation of the

convention in order to determine the orbital.

Popular controllers are Fanuc, Heidenhain,

Siemens, Fagor, Anilam and Hass. Each

controller is the format of parameters and

method of connecting individual through the

software connection. [1, 2, 6]

2.2. Model of integrated CAD/CAM/CNC

Based on some investigated [2, 6, 7], a model

LAN-DNC network to integrating CAD/CAM

system with the CNC machines was

constructed by the authors, and is shown in

Figure 1. This was done in order to connect

the CNC machine with the computer or to
