Abstract: When the numerical simulation of spinning forming is carried out by Abaqus finite element software，the wall thickness of spun workpieces can not be obtained quickly and accurately，and the process can not be visua-lized． In order to solve this problem，a method of automatic measurement and visualization of the wall thickness of spun workpieces based on Abaqus numerical simulation was proposed． Automatic measurement of wall thickness of spun workpieces was realized through coding in Python language． Using ＲSG dialog builder to customize menu in-terface，a toolkit for automatic measurement of wall thickness of spun workpieces based on Abaqus was developed．Automatic measurement of wall thickness of conical parts，cylindrical parts with inner ribs and other spinning parts was realized，and the results were displayed in the form of contour． By comparing the measurement results with the automatic wall thickness measurement tool and the three-dimensional software，it is found that the developed toolkit can accurately measure the wall thickness distribution of various kinds of spun workpieces．
