Method for removing supports of thin-walled ring-shaped structural parts manufactured by laser additive manufacturing, its applications and support removal aid

Abstract

The present application relates to the field of laser additive manufacturing, in particular to a support removal method for laser additive manufacturing of thin-walled ring structure parts and application and a support removal auxiliary device. The support removal method for laser additive manufacturing of thin-walled ring structure parts provided by the present application can monitor the deformation amount of the part in real time during the support removal process, can find deformation in time and inhibit large size deformation of the part through air cooling, and greatly improve the forming quality. In addition, the deformation amount of the part is collected in real time through a piezoresistive sensor, and the cooling process is synchronized, which is simple to operate, simple in structure, low in equipment cost, good in applicability, effectively solves the deformation and cracking problem of laser additive manufacturing of thin-walled ring structure parts, and greatly improves the manufacturing efficiency and forming quality. At the same time, the piezoresistive sensor, the position, size and shape of the air outlet hole of the temperature control system are designed, so that the processing amount is minimized and the use of materials is minimized while the function is fully exerted.
