Rigid foam with 3D (three-dimensional) molded surface and processing method of rigid foam

The invention relates to numerical control machining of materials, and discloses rigid foam with a 3D molded surface and a machining method of the rigid foam, and the machining method at least comprises the steps of machining position and size design, reserved supporting point design, foam rough blank machining and reserved supporting point cleaning. By means of the specific machining method, molded surface positioning tools used during foam machining can be reduced and omitted, especially for foam machining of complex molded surfaces, meanwhile, the requirement for machining machine tool equipment can be lowered, meanwhile, by adjusting and controlling machining parameters, the precision of the machined shape can be higher, and a target foam product better meets the design requirement. 本发明涉及材料的数控加工，公开了一种具有3D型面硬质泡沫及其加工方法，至少包括设计加工位置和尺寸、设计预留支撑点、泡沫粗坯加工、清理预留支撑点。本发明通过特定的加工方法，能够减少和免除泡沫加工时用的型面定位工装，尤其对于复杂型面的泡沫加工，同时可以降低对加工机床设备的要求，同时通过调控加工参数，能够使所加工形状的精度更高，使目标泡沫产品更加贴合设计要求。
