Abstract

The invention discloses a disc rotary type multi-channel electron beam rapid forming method. The method comprises the steps that firstly, three-dimensional part models are placed on a forming zone forslicing; secondly, a polar coordinate system is established, and position information of the three-dimensional part models is determined; thirdly, scanning track points of the three-dimensional partmodels are obtained through calculation; fourthly, powder paving and forming zone positioning are carried out; fifthly, single-layer solid sheet layers are obtained through powder scanning melting; sixthly, the forming zone is reset; and seventhly, a forming base plate is lowered, the processes in the step four to the step sixth are repeatedly executed, and the single-layer solid sheet layers on the forming base plate are stacked layer by layer to obtain a three-dimensional part. By means of the disc rotary type multi-channel electron beam rapid forming method, the polar coordinate system is established on a disc working table of disc rotary type multi-channel electron beam rapid forming equipment to accurately determine the position information of the two or more three-dimensional part models on the disc working table, then scanning melting is carried out, rapid forming of the three-dimensional parts in different materials is realized, and the part forming precision is improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a disk rotating multi-channel electron beam rapid prototyping manufacturing method. Background technique [0002] Electron beam selective melting technology (Electron Beam Selective Melting, EBSM) and selective laser sintering technology (Selective Laser Sintering, SLS) are two kinds of additive manufacturing technologies widely used at present. Hardware control technology can directly convert 3D CAD models into entities. Theoretically, any heat-bonded powder can be used as a raw material for additive manufacturing, such as polymers, ceramics, metal powders, and various composite powder materials. Electron beam selective melting rapid prototyping technology is that the electron beam scans line by line according to the pre-planned path driven by the deflection yoke, melts the laid metal powder, accumulates layer by layer, and manufactures the required m...
