A numerical study of multi-pass design based on Bezier curve in conventional spinning of spherical components

Abstract

Abstract. Bezier curve has been widely used as the roller path in conventional spinning. In this paper, Finite Element model with parameterized 2-pass conventional spinning tool paths based on quadratic Bezier curve is developed to explore the influence on the wall thickness reduction of spherical components. The results show that the first path has significant effect on wall thickness distribution and the selection of parameter values in tool path is crucial for thickness distribution.

An analytical model integrated with toolpath design for wrinkling prediction in conventional spinning

“…In three recent studies, Li et al (2014) firstly adopted the quadratic Bézier curve to parameterise the toolpath profile design for the first-pass of the multi-pass spinning. Polyblank and Allwood (2015) also used the Bézier curve based toolpath profile parameterisation for the first pass, while Gan et al (2016) worked on the two-pass conventional spinning. However, these studies mainly focused on investigating the effect of the toolpath profiles on the roller tool forces, the accuracy of the spun part geometry and thickness distribution but not aimed at developing an effective wrinkling prediction method for the multi-pass conventional spinning.…”

Texture Evolution of a Rolled Aluminum Sheet in Multi-Pass Conventional Spinning

“…The validity of the FEM model was evaluated by comparing the height and thickness distributions of the workpiece, formed experimentally, with the results calculated by FEM [3][4][5][6]. For designs wherein the workpiece configuration was estimated by FEM, Metals 2020, 10, 793 2 of 10 the height and thickness of the workpiece, obtained due to the roller path, were evaluated [7][8][9][10][11]. Recently, stress distribution in workpieces was reported [12].…”
