A computer - matching - material control algorithm arming to minimize the accumulative errors 一種用于減小累計(jì)誤差的微機(jī)配料控制算法
Compared with finite element method , this method is more convenient and there does not exist any accumulative error , and easily to simulate environmental temperature change 相對(duì)通常使用的有限單元法,計(jì)算更加靈活并不存在時(shí)段累積誤差,對(duì)環(huán)境溫度波動(dòng)的模擬也更加方便。
The study , analysis and calculation of accumulative error in chain measurement length are conducted and its rational value accepted commonly by enterprises is determined in this paper 摘要對(duì)鏈條測(cè)試長(zhǎng)度累積誤差值進(jìn)行了研究、分析和計(jì)算,給出了合理的誤差值,可為生產(chǎn)企業(yè)普遍采用。
The paper put forward a new method of machining different top and bottom shaped workpieces based on difference interpolation theory , the method calculated the displacement of prp and psp plane to equivalent accumulated displacements of uv and xy plane , which was of advantages for simplifying programming , reducing accumulative errors caused by traditional calculation method and increasing machining precision 摘要提出了基于差分插補(bǔ)理論的加工上下異型面工件的新方法,把工件的下表面(參考平面, prp )和工件的上表面(第二平面, psp )上的插補(bǔ)運(yùn)動(dòng)位移換算為uv及xy兩平面上的位移疊加,具有簡(jiǎn)化編程、減小傳統(tǒng)計(jì)算方法產(chǎn)生的累積誤差、提高加工精度的明顯優(yōu)點(diǎn)。
