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.

Recently, in the products through injection molding process, it was manufactured to apply more than two resins according to parts of functionality and aesthetic appreciation and double-injection molding process was for that. Double-injection molding is some kind of technology that two resins was injected in one mold at the same time. Thereby, it is had advantage for productivity. In earlier study, first and second injection molding cycle time was different for each other. Because, each two resins were considered independently in injection molding analysis research that it was drew the conclusions of injection molding process conditions. In this study, the first and second injection molding cycle time was drew conclusions to consider the characteristics of double-injection molding process that has a same cycle time during first and second injection molding. The injection time, packing time and cooling time that were made up the injection molding cycle time, were decided to consider first and second deflection of products, gate part frozen time and whole parts frozen time for each parts.
