在高速精密磨削可转位刀片周边时,由于采用双顶尖油压夹紧刀片,再通过在刀片上产生的摩擦力和油压力来约束刀片的6个运动自由度,造成夹具结构刚性相对薄弱。为此,针对极限夹紧工况时夹具的受力变形进行了分析,通过结构改进与误差补偿,提高了夹具定位精度和磨削加工的可靠性。In high speed precision grinding the peripheral of indexable inserts,due to the double chucks clamping the blade by the oil pressure,and through the friction and the oil pressure produced in the blade to restrain the insert'six movement degrees,all these w ill make the fixture structure rigid become relatively w eak.Therefore,the paper analyses the fixture deformation in the limit w orking condition,and improves the accuracy of the fixture location and the reliability of the grinding process through the structure improvement and error compesation.国家国家科技重大专项(2010ZX04001-162
