Additional and subtraction material composite processing equipment

Abstract

Additional and subtraction material composite processing equipment comprises an additional material manufacturing device, a cleaning device, a subtraction material processing device, a transfer device and a positioning device. The additional material manufacturing device comprises an energy source mechanism and a forming mechanism; the forming mechanism comprises a forming cavity and a forming substrate arranged in the forming cavity; the energy source mechanism is used for forming and repeated forming of powder on the forming substrate; the transfer device is used for transferring the forming mechanism and workpieces positioned on the forming substrate between two optional workstations of an additional material manufacturing workstation, a cleaning workstation and a subtraction material processing workstation; the cleaning device is used for cleaning the workpieces on the forming substrate; the subtraction material processing device is used for processing the workpieces on the forming substrate; and the positioning device is used for positioning the forming substrate. Subtraction material processing can be added between semi-formed workpieces and formed workpieces of additional material manufacturing, subtraction material processing on inner and outer surfaces of the semi-formed workpieces can be implemented accurately in time, the applicability and processing efficiency of the formed workpieces are improved, positioning is accurate, and the quality of the formed workpieces is controllable.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to an additive and subtractive composite processing equipment. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, is a "bottom-up" manufacturing method through material accumulation, which is different from the traditional processing mode of raw material removal, cutting, and assembly. Generally, after the overall molding is made by additive manufacturing, it is necessary to perform subtractive processing processes such as milling off the machining allowance or polishing the surface. However, the inner surface of the workpiece formed by additive manufacturing, especially the molded workpiece with complex structure, is difficult to be processed by subtractive material, which limits the applicability and processing efficiency of the molded workpiece. And if the workpiece moves between the additive manufacturing station and the subtractive m...

Problems solved by technology

However, the inner surface of the workpiece formed by additive manufacturing, especially the molded workpiece with complex structure, is difficult to be processed by subtractive material, which limits the applicability and processing efficiency of the molded workpiece

And if the workpiece moves between the additive manufacturing station and the subtractive processing station, causing the position of the workpiece to change at the same station, the signal sent by the control mechanism will be inaccurate, which will make it difficult to control the quality of the formed workpiece
