Embodiment 1

[0052] This embodiment takes 316L stainless steel to manufacture metal parts with hollow structures as an example, using such as figure 1 The shown composite manufacturing system of additive manufacturing and laser preheating assisted subtractive cutting specifically includes the following steps (note: the specific parameters involved are only typical values, in order to better express this invention, do not limit the scope of this invention Effective range of use):

[0053] (1) Generate the additive path and the subtractive path.

[0054] (2) Vacuumize the sealed cavity, and then pass argon gas into the sealed cavity, so that the oxygen content in the sealed cavity is lower than 0.3%.

[0055] (3) The control unit 10 switches the additive manufacturing module to the top of the processing substrate 3 through the module switching unit, turns on the powder feeder 1, and the spherical 316L stainless steel powder is ejected from the powder feeding nozzle 2 to the processing subst...

Abstract

The invention discloses a composite manufacturing system and method of additive manufacturing and laser preheating auxiliary subtractive cutting. The system comprises an additive manufacturing module,a subtractive cutting module, a laser preheating module, a module switching unit, a control unit and a workbench. The additive manufacturing module, the laser preheating module and the subtractive cutting module are all mounted on the module switching unit. The additive manufacturing module, the subtractive cutting module, the laser preheating module, the module switching unit and the workbench are all connected with the control unit. The workbench is used for containing a part to be formed. According to the composite manufacturing system and method, by means of the online laser preheating module, the cutting performance of the material can be effectively improved, the service life of cutters is prolonged, and the requirement of a traditional additive and subtractive manufacturing processon an additional annealing heat treatment process is completely eliminated. The additive and subtractive composite manufacturing system including a laser assisted cutting module can produce parts with high complexity and high precision.

Description

technical field [0001] The invention belongs to the field of parts processing and manufacturing, and in particular relates to a composite manufacturing system and method of additive manufacturing and laser preheating-assisted subtractive cutting. Background technique [0002] Traditional subtractive manufacturing methods are gradually unable to meet the increasingly urgent needs of high-end parts design and rapid manufacturing in the industrial field in recent years. The additive manufacturing technology that has emerged in recent years has made up for the shortcomings of traditional manufacturing methods due to its series of advantages, such as speed, flexibility, and low waste, and is suitable for the rapid manufacture of complex parts. However, the method of additive manufacturing also has many insurmountable disadvantages, such as high surface roughness, obvious thermal stress, easy deformation, poor precision, etc., which limit its application in the field of advanced p...
