摘要
Abstract
The arc temperature of plasmna arc is twice as high as that of common arc,while the arc divergence is very small,and HAZ is very small in plasma arc welding,so the molding precision of the parts made by plasma arc welding is very high.And there is no defect in the high costs of laser and electron beam equipments,therefore,the use of plasma arc as heat source for material manufacturing has become a research hotspot.According to the main characteristics of metal rapid prototyping and technological process,a plasma arc metal rapid prototyping equipment control system is designed with CP1H-PLC as the control core,and is equipped with the MT8070iH3 touch screen and MY2NJ-OMRON intermediate relay unit.This control system is adopted in a test under suitable conditions,the forming parts meet the design requirements,which proves that the control system is reliable and stable in performance.The results show that the appropriate molding process parameters of the PTA material manufacturing are preliminarily grasped.关键词
