Embodiment 1

[0089] This embodiment provides a processing method based on a synchronous processing device of mechanical subtractive material and laser additive material, on the surface of the workpiece to be processed to additively manufacture a multi-layer metal deposition structure, which specifically includes the following steps:

[0090] 1.1. Set the optimized milling tool 4 processing parameters: milling tool 4 feed speed V 1 , Milling tool 4 speed V 2 , Milling depth H 1 , the height H between the bottom of the suction pipe 5 and the surface of the workpiece to be processed 2 ;Laser parameters: the distance H between the laser focus O and the surface of the workpiece to be processed 3 , laser power, laser moving speed, and the laser moving speed and the feed speed V of the milling tool 4 1 Equal; powder feeding parameters: powder feeding rate and powder particle size, and input the optimized processing parameters into the control program, and determine the chemical composition of ...

Embodiment 2

[0095]This embodiment provides a processing method based on a synchronous processing device of mechanical subtractive material and laser additive material, which is used to additively manufacture a gradient structure metal deposition structure on the surface of the workpiece to be processed. The processing method provided in this embodiment is the same as that in Example 1. The method is the same, the difference is that the last step adopts the following method:

[0096] After the first layer of additive manufacturing is completed, the mechanical subtractive material and laser additive synchronous processing device are lifted by the manipulator 8 to an average height of the deposited layer, and steps 1.1 to 1.3 are repeated, that is, the previous metal additive manufacturing After that, it is necessary to reset the chemical composition of the powder, and adjust the milling tool 4 processing parameters, laser parameters and powder feeding parameters in time until the predetermin...

Abstract

The invention provides a mechanical subtractive and laser additive synchronous machining device and method. The device is suitable for being arranged above a workpiece to be machined, the mechanical subtractive and laser additive synchronous machining device comprises a laser head, a powder feeding head, a fixed base, a milling tool and a dust suction pipe, and the laser head is suitable for emitting laser beams and irradiating the surface of the workpiece to be machined; the powder feeding head is arranged on the side, close to the to-be-machined workpiece, of the laser head, a plurality of powder feeding nozzles are evenly arranged on the side, close to the to-be-machined workpiece, of the powder feeding head in the circumferential direction, and the powder feeding nozzles are suitable for spraying powder to the focus of the laser beams; the fixed base is arranged on one side of the laser head in the length direction of the laser head; and the milling tool and the dust suction pipe are arranged on the fixed base and arranged on the side close to the to-be-machined workpiece, the milling tool is parallel to the center line of the laser beams, and a pipe opening of the dust suction pipe faces the milling tool. The problem that the quality of the to-be-machined workpiece is affected due to the fact that too many chippings exist in the subtractive process is solved.

Description

technical field [0001] The invention relates to the technical field of additive and subtractive material manufacturing of metal parts, in particular to a simultaneous processing device and method for mechanical subtractive material and laser additive material. Background technique [0002] Additive manufacturing technology, as one of the important application technologies of high-end intelligent equipment in the current manufacturing industry, reflects the industrial manufacturing level of a country and effectively makes up for the low efficiency and non-integrated forming of complex parts by traditional subtractive manufacturing technology based on CNC machining. Shortcomings. However, with the further improvement of the forming dimensional tolerance and surface finish of parts by intelligent equipment, parts manufactured solely by additive manufacturing technology methods cannot meet the design accuracy of the product, and usually still need to be further processed by trad...
