Modern various machine and equipment are more than on the gear reducer, generally USES bearing hole processing, and currently 1ta series boring coordinates are in single points, so in mass production to ensure its hole spacing tolerance, and low efficiency.
A fine molding machine is a special machine, when using a series of molding method. Once processed clamping workpiece, hole spacing in design, and when the machine has two of the coaxial when spindle box, while processing by rail, which not only ensures the transmission distance between accuracy, but also guarantee the hole, and greatly improve the coaxial tolerance of machining efficiency. Can realize automation, production line. It meets the modern production accuracy and efficiency.
This paper introduced a series of molding machine structure, working principle and control method, and automatic assembly line control principle and realization method.

AC-frequency parameters of the development of digital multimeter

Abstract

Multimeter use of single-chip control, computing functions, according to the formula of discrete points and discrete Fourier transform, the power system parameters based on a sampling of ideas to exchange, at the same time all the way to achieve the frequency of the alternating current frequency, voltage rms, current RMS measurements. Calculation and analysis software of active power, reactive power, power factor, fundamental RMS voltage, RMS voltage total harmonic parameters such as the use of digital potentiometers, the system self-calibration, automatic conversion range. System to fully exploit the computing power of single-chip software instead of hardware circuits, so that greatly simplify the hardware circuit.
Digital Multimeter-frequency alternating current parameters can be achieved along the way at the same time-frequency alternating current value of the various power, voltage rms, current rms measurement parameters. It uses single-chip control, computing features to the software instead of hardware circuit design, the use of alternating current sampling methods, using a variety of calculation and analysis software, RMS, active power, reactive power, power factor and other parameters, so that greatly simplify the hardware circuit .
The system uses a digital potentiometer to facilitate accurate adjustment, long service life, the impact of the external environment by a small, stable performance characteristics of the circuit design with self-calibration, range can be automatically converted, high measurement accuracy, stable performance and so on.

楼主好狠哪~~~~哎，到学校图书馆查找呗。。。英文 查找，用google什么的在线翻译。。其实，没那么困难滴，，，过关就看个人造化啦~
祝楼主好运~
