【正文】 kind of gap existence, when movement direction change, starts the section time to be able to cause inevitably actuates the part wasting time, appears the instruction pulse to push the motionless functional element the aspect. This has affected the engine bed processing precision, namely the instruction pulse and actual enters for the step does not tally,has the processing error therefore, the splitring numerical control system all establishes generally has the reverse gap error pensatory function, with by makes up which wastes time the step reverse gap difference pensates is first actual reverse enters for the error, converts the pulse equivalent number it, pensates the subroutine as the gap the output, when the puter judgment appears when instruction for counter motion, transfers the gap to pensate the subroutine immediately, pensates the pulse after the output to eliminate the reverse gap to carry on again normally inserts makes up the movement. 2. often the value systematic characteristic position error pensates A kind of storehouse by transfers for the designer. Like this in the ponents design stage, the designer only must input the characteristic the parameter, the system direct production characteristic example model: We must save the related characteristic class in the database the structure information, the database table collection are use in saving this part of related information. According to the characteristic type definition need, we defined the characteristic class code table, the characteristic class edition information have outstanding shown the characteristic type。 Defined the characteristic class structure outstanding to reach the characteristic class the structure。 The characteristic size table, the characteristic shape position table of limits, the characteristic surface roughness table has recorded the characteristic pro
