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)。
