The laser beam cutting machine integrated NC system is designed by using multiple controllers. The data communication between NC and laser generator is realized by RS485 bus. PIC bus is connected to DSPIC controller, which drives AC servo motor to run. Meanwhile, the design of system hardware circuit is introduced and parts of the circuit diagrams are shown. Design description of the system software is also given, which is to achieve the integrated control of laser and machine.

This paper presents a kind of chip-less pipe cutting machine feeding mechanism and briefly introduces its working principl. With the application of Ansys software, the cutter's under pressure of this tool is deduced. Then calculation of the motor's maximum speed, equivalent load inertia and equivalent load torque by this method , the chip-less pipe cutting machine's AC servo motor is determined and its capacity is checked.

In the field of machining industries it is always required to improve the accuracy of precise products, die and molds. The feed drive system for the machine tools consists of an AC servo motor, an amplifier and rolling elements etc. It is well known that the nonlinear behaviors of the rolling elements influence the motion accuracy of the feed drive system. However, in spite of the analysis of static behaviors have been done, the dynamic behaviors are not so examined. Our special interest is how to control the nonlinear behaviors of the rolling elements and to operate the feed drive system with high accuracy. In order to model the nonlinear behaviors of the feed drive system, we measure the transient response when the step inputs of microscopic displacement are input to the AC servo motor and the detail analysis will be done. Experimental results show that the step responses become slow as the input displacement becomes microscopic. It means that with the ball bearing built into the AC servo motor used to feed driving system have the nonlinear behavior in microscopic displacement range.

Semisolid forging process requires special movement of the ram, until now only achievable with hydraulic presses. The upper die, placed on the press ram, must move fast during forming of the component in order to reduce segregation phenomena, and, once the part is shaped, the die must squeeze the material so that the contraction of the material is overcome and no shrinkage defects are formed. Traditional mechanical presses are not able to reproduce this kind of cycles, only possible with hydraulic presses. The introduction of servo motors in mechanical presses makes possible the achievement of those requirements, and, therefore, the use of these presses for the semisolid forging processes. The main characteristic of this type of machines is the elimination of the flywheel and the clutch; in the solution proposed by the press builder Fagor, the AC servo motor drives the ram of the press by using a transmission based on gears and a crank. This paper presents some of the results achieved during the semisolid forging of A356 aluminium alloy using a 400 tons Fagor servo motor driven mechanical press installed at the University of Mondragon.
