l design personnel through the procedure inquiry function, inquires the ponents information from the sharing database which needs, carries on the interactive technological design. Thus has facilitated the CAPP ponents information acquisition, enhanced the technological design efficiency. When carries on the NC programming using UG, may from the sharing database gain the craft and the manufacture information which needs, carries on various working procedures the knife axle design and the processing simulation establishes an absolute zero spot on the numerical control engine bed, the actual various coordinate axes syzygy pletely position error, makes the curve in order to determined pensates the spot. Attempts l to show is an actual position error curve, (error) carries on this curve ycoordinate take the pulse equivalent as the unit the division, makes the horizontal line, each horizontal line and the curve point of intersection namely pensates the spot for the goal. Chart 1 the center 1 to 6 o39。 clock place position errors for, needs to do reduces the pulse to pensate。 But needs to carry on 6 to 9 adds the pulse to pensate in the chart the shadow partially for to pensate the area. Compensates the range of points these to bee the error The calibration corrections stores the puter, when work table by zero displacement in position, installs sends out the absolute zero point localization signal in the absolute zero point micros witch, later puter as necessary will send out the goal to pensate to pensate the signal, will carry on the position error to the engine bed to pensate. The cosine generator assigns slide guage initiation signal a electricity and by step of transmission. 3. feedbacks pensates the openloop control Chart 2 has produced this kind of system schematic diagram. This system surveys two parts by the openloop control and the induction synchromesh direct position to be posed. Here position examination does not serve as the position the feedback, but is pensates the feedback as the position。
