【正文】 起停誤差等都會影響定位精度。 On the other hand this instruction pulse supplies the induction synchromesh the measurement system (namely digitally, cosine generator), as position demand signal a by. The work in the warning way induction synchromesh this time not only is the position sensor, also is the parator, it by, The cosine generator assigns slide guage initiation signal a electricity and by step of transmission. 4. conclusions Under the CIMS environment the technology which develops unceasingly based on characteristic ponents information modeling, how enhances the ponents order of plexity which the characteristic design can plete。 The size table, the shape position table of limits, the surface roughness table saved all ponents characteristic data message. In the characteristic level, using characteristic ID, geometry principal linkage and so on essential factor ID, size ID, mon difference ID, roughness ID carries on the data retrieval. We apply this ponents information model database under the factory environment some module CAD in the AM integrative system, has realized CAD and the CAPP characteristic information sharing well. Main use readymade CAD/the CAM software (Unigra phics 1I) carries on the product design and the NC programming in this system, and through carries on two times of developments gains ponents to this software the size information。英文文獻翻譯： 原文： The open system merit of Computer Numerical Control The open system merit is the system simple, the cost low, but the shorting is the precision is low. The reverse gap, the guide screw pitch error, stop inferiorly can affect the pointing accuracy by mistake. Following several kind of improvements measure may cause the pointing accuracy distinct improvement. 1. reverse gap error pensates The numerical control engine bed processing cutting tool and the work piece relative motion is depends upon the drive impetus gear,the guide screw rotation, thus the impetus work floor and so on moves the part to produce moves realizes. As traditional part gea
