influencing Factors of AZ31B Magnesium Alloy Thermal Incremental Forming Bottom Convex
Keywords:
Magnesium Alloy, Incremental Forming, Precision, Convex.Abstract
Bottom convex is one of the important factors that affects the precision of single-point incremental forming workpiece. In this paper, numerical analysis and experimental verification are combined to study the influence of the bottom side length, forming temperature, interlayer spacing and other factors on the convex, the causes of the convex and the influence rule of each factor on the convex are also analyzed. The results show that the smaller the side length of the bottom surface, the smaller is the convex caused. The smaller is the interlayer spacing, the smaller the convex caused;The convex is affected by the forming temperature through changing the forming property of the material, and the influence of the bottom side length shall also be taken overall consideration for the size of the convex.
