Deform 3D Simulation and Experimental Investigation of Fixtures with Support Heads

Abstract

Thin-walled aluminium parts are employed in a variety of industries, including construction and aerospace. If they are treated to a greater quantity of milling, they are more resistant to deformation. As a result, the stability of the work parts degrades, and the surface roughness increases as a result of this factor. This work proposes the use of a well-designed fixture with support heads to lessen the deformation produced by square thin-walled aluminium plate milling. The suggested fixture system's support heads are comprised of high-carbon steel. The milling experiment is carried out in a CNC Machining centre under machining settings similar to DEFORM 3D-Simulation. The experimental results are validated by measuring surface roughness with the SURFTEST SJ-210 portable Surface Roughness tester in two scenarios: without and with fixtures used during the milling operation. As a result of employing this fixture with support heads to reduce deformation, surface roughness values are reduced by a minimum of 3% to a maximum of 19%. As a result, it has been demonstrated that the proposed fixture with support head may be used to reduce distortion in thin-walled aluminium plates
