Finite Element Analysis of Deformation of the Multipoint Flexible Clamped Thin-Wall Component during Machining

Abstract:

A study on deformation of multipoint flexible clamped thin-wall components during numerical control drilling in vertical direction downward is presented. The finite element model of multipoint flexible clamped thin-wall component during machining is established with program ANSYS, and a static analysis of deformation of the model is conducted. The laws of maximum deformation under different skin thickness, under different cutting force and on the 3 special machining paths in the cut area are obtained. The results show that the maximum deformation is linear with cutting force and exponential with skin thickness, and the function curves of the maximum deformation on the 3 special machining paths are all different, the function curve 2 is the composite superposition of the function curve 1 and the function curve 3.
