Based on the coordinated control principle of two coordinated axes, this instrument has two kinds of work modes which are the text and draw output modes, also this paper introduces the design and realization of some main interface circuits, finally the software design for the two kinds of output modes are described.

Aiming at the problem of track association for 2D radar and infrared,a method has been proposed in this paper,based on the MAP criteria of track correlation events and Nearest Neighbor(NN),with the integration of state information correlation and estimation fusion,which has utilized the radar contacts,tracks and historical mformation.

Two new correlative algorithms are proposed for networking system in this paper, which are track association and estimation fusion based on 2D radar/infrared and 2D Radars, to solve the .

On the hardware environment of the 2-axle link-moving CNC milling machine with impulse turntable and personal computer, the application of the CAD/CAM system of the cylindrical cam is introduced according to the cam profile curve expanding principle and the Pro/E software package.
