This paper presents the implementation of an internet-based facility for the drilling process simulation, which complies with TCP/IP and is supported by Browser/Server model. The process simulation is one of pivotal technologies and implemental techniques of the internet-based agility manufacturing technology. A network architecture model is developed with the WebServer toolbox of MatLab. The complicated drilling process is studied. Semi-experimental mathematic models of drilling force and torque are established. Users input different machining parameters in client-side and then they will get the simulation curves of cutting forces and torques and can evaluate the simulation results. At last, optimum machining parameters can be chosen by users via internet.
