The target of this paper is the development of Web-based monitoring & control system which is for effective and economic management of mold manufacturing process. This system has three module; G-code Control, Monitoring Module and Result analysis module. Also, as the environment of development is based on internet, this system which is possible to the remote site management of manufacturing process works on Web. To be possible to control the manufacturing monitoring by client, each module is made ActiveX control and is based on socket communication. This system makes the foundation which is possible to manage the mold manufacturing process efficiently from remote site by matching real-time monitoring with manufacturing process in factory using G-code control and displaying the result of manufacturing using Ch-CGI.

In this study, the efficiency of ceramic micro cutting tool with abrasive-type was evaluated by basic micro cutting experiments. Generally, micro drill and endmill made of tungsten-carbide which have sharply cutting edge are worn out rapidly. Therefore, ceramic micro tool which has minute bump feature was proposed in this study. In experiments, micro hole and slot shape were fabricated by ceramic micro tool. Finally the quality of fabricated hole and slot were evaluated and tool wear trend was observed by microscope.

In this study, a research on the micro cutting process with the mold core material at low temperature environment was performed. In macro cutting fields, the cryogenic cutting process, mainly turning process, has been applied to cut the refractory metal but, the serious problems may be generated in micro cutting fields by the cryogenic condition. However, if the proper low temperature is applied to micro cutting area, the cooling effect of cutting heat is expected. Such effect can make the reduction of tool wear and burr formation, For verifying this process, the micro cutting experiment at low temperature was performed and SEM images were analyzed.

In this paper, a basic study on micro cutting process with SM20C at low temperature environment was performed. In macro cutting fields, the cryogenic cutting process has been applied to cut the refractory metal but, the serious problem may be generated in micro cutting fields by the cryogenic environment. However, if the proper low temperature is applied to micro cutting area, the cooling effect of cutting heat is expected. Such effect can make the reduction of tool wear and burr formation. For verifying this possibility, the micro cutting experiment at low temperature was performed and SEM images were analyzed.
