Under combining the interpolation theory with non - linear capacity and parallel calculation structure of artificial neural network ( ann ) , a software implement technique for fine interpolation of the 1pt + 3tps hmt is researched . the roughing interpolation and fine interpolation algorithm of hmt are introduced in the first . the interpolation controller is constructed by bp neural network and the training with the lm algorithm to the controller is carried on 給出了混聯(lián)機(jī)床粗插補(bǔ)和精插補(bǔ)算法,以bp神經(jīng)網(wǎng)絡(luò)構(gòu)建了插補(bǔ)控制器,用lm算法對(duì)控制器進(jìn)行訓(xùn)練,利用matlab中的神經(jīng)網(wǎng)絡(luò)工具箱進(jìn)行了仿真,驗(yàn)證了其可行性和有效性,為實(shí)現(xiàn)面向制造過程的高速實(shí)時(shí)插補(bǔ)方面,提供了一種新的插補(bǔ)控制器結(jié)構(gòu)。
