Abstract: A process-orientated design method for machine tool structures comprises the steps of: (A) Defining design conditions including initial configurations, cutting requirements and boundary conditions for the machine tool; (B) Calculating cutting ability to generate information realizing a relationship between a maximum cutting depth and a spindle speed of the machine tool based on the initial configurations and the cutting requirements; (C) Performing an optimization to generate a frequency range for optimization based on the information relating the maximum cutting depth and the spindle speed; (D) Performing structural topology optimization to generate an optimized model based on the frequency range for optimization, the initial configurations and boundary conditions; and (E) Determining whether the optimized model fits the constraint condition; if positive, ends the design steps, and otherwise repeats steps (B)˜(D) until an optimized model fits the constraint condition appears.

Abstract: A method and an apparatus for transmitting real-time streaming data are provided. The apparatus has a first terminal, a second terminal, and a relay server. Real-time streaming transmission paths between the first terminal and the relay server as well as between the second terminal and the relay server are established, and the first and the second terminals can obtain information from each other. Whether the first and the second terminals are directly connectable or tested. When the first and the second terminals can be connected directly, the first terminal alters the real-time streaming transmission path directly to the second terminal without passing through the relay server. When the second terminal can be connected directly to the first terminal, the second terminal alters the real-time streaming data transmission path directly to the first terminal with passing through the relay server.
