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
具有支撑头的夹具变形三维仿真与实验研究
薄壁铝零件应用于各种行业,包括建筑和航空航天。如果对它们进行更多的铣削处理,它们就更能抵抗变形。结果,工件的稳定性降低,并且表面粗糙度由于该因素而增加。这项工作提出了使用一种精心设计的带有支撑头的夹具来减少方形薄壁铝板铣削产生的变形。建议的夹具系统的支撑头由高碳钢组成。铣削实验在CNC加工中心进行,加工设置类似于DEFORM 3D仿真。实验结果通过使用SURFTEST SJ-210便携式表面粗糙度测试仪在两种情况下测量表面粗糙度进行了验证:在铣削操作中不使用夹具和使用夹具。由于采用这种带有支撑头的夹具来减少变形,表面粗糙度值从最小的3%降低到最大的19%。结果表明,所提出的带有支撑头的夹具可用于减少薄壁铝板的变形
