The invention relates to a friction material adding and reducing integrated device and a machining method. The friction material adding and reducing integrated device and the machining method are used for integrating the material adding process and the material reducing process of a workpiece. A friction material adding part, a micro-forging part and a material reducing part are designed as necessary structures. A material adding manufacturing part comprises a position changing machine, a rotary workbench, a rotary tool head and a feeding device and is used for solid-phase material adding manufacturing forming of a part; the micro-forging part comprises forging equipment and a motor and is used for increasing the compactness of the formed part, reducing internal defects and improving the mechanical property; a scanning detection part comprises a laser three-dimensional scanner and three-dimensional model contrastive analysis software and is used for monitoring and scanning the shape of the workpiece obtained after material adding manufacturing, comparing the workpiece with a target part for analysis and determining the area needing material reducing; the material reducing part comprises a rotary tool magazine capable of switching the machining manners of turning, milling, planing, grinding and the like and is used for precision machining of the part obtained after material adding; and a numerical control part is used for material adding-micro-forging-material reducing process control of the formed part.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, and specifically relates to a friction additive integrated equipment and a processing method, which are mainly used for integrating the additive process and the subtractive process of workpieces, reducing the working space and improving the production efficiency. Background technique [0002] Friction additive manufacturing (also known as 3D printing) is to use the computer to generate a three-dimensional solid model of the target part, slice and layer the model according to a certain thickness, and then under the control of the numerical control system, according to a certain path, through the friction tool head and The frictional heat between printing materials (layered or filamentary) is used as a heat source to accumulate printing materials layer by layer to form a three-dimensional part. Friction additive manufacturing is a solid-state additive manufacturing technology that can avoid th...

Problems solved by technology

[0003] The current friction additive manufacturing technology has the following deficiencies: (1) The parts prepared by the current friction additive manufacturing technology generally have defects such as poor compactness, resulting in low mechanical properties of the parts; The side flow leads to rough surface and poor forming quality of the formed parts, so the geometric accuracy and surface quality of the additive parts often cannot meet the design requirements; (3) In order to improve the surface quality of the formed parts, although laser and arc additive manufacturing Additive-subtractive equipment already exists in the field, but it is often necessary to transport the workpiece to another machine tool for milling after the additive manufacturing is completed, which greatly increases the complexity of the equipment and the difficulty of processing

[0004] After searching by the applicant, the applicant found that there is no integrated equipment that can simultaneously complete the functions of material addition-micro-forging-subtraction
