| Abstract: | The paper introduces the formingprocess, main features and basic construction ofthe first MEM(melted extrusion manufacturing)system in China. Based on the analysis,the wheeldiagram of most factors which influence on theforming accuracy is proposed. According to prac-tice. the major factors which influence on the ac-curacy, including data processing, mechanicaland NC system, materiaI, process planning andcontrolling. are analysed,and the methods to im-prove the accurary are given out, especially fila-ment width compensation, respond delay com-pensation and anticipatory control of the fila-ment feeding. |
