A clock signal generating circuit includes a crystal oscillator, a phase compensation circuit, a negative resistance compensation circuit, and a high pass filter circuit. The crystal oscillator generates a clock signal. The phase compensation circuit compensates a phase of the clock signal. The negative resistance compensation circuit filters phase noises of the clock signal. The high pass filter circuit filters low frequency noises of the clock signal.

A computer-aided manufacturing system for sheet-metal punching includes client computers (), a server (), and a database (). The client computers are used for transmitting client drawings to the server, and obtaining machining drawings from the server. The database is used for storing the client drawings, punching tool information, turret information, punching tool layout information, relevant production management information, machining drawings of workpieces, and statements for control of machining processes. The server is connected to a production management system () through a network (), and is used for automatically selecting, mounting and laying out punching tools, optimizing turrets, simulating machining of workpieces, and exporting CNC (computer numerical control) code files, types of machines, machining information on workpieces and materials of the workpieces to the production management system in order to have statements for control of relevant machining processes generated. A related computer-aided manufacturing method for sheet-metal punching is also provided.
