[0002] In recent years, the demand for high-strength, high-rigidity lightweight materials in aerospace equipment has been increasing.

[0046] With reference to the accompanying drawings: the technical solutions in the embodiments of the present application will be apparently and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor belong to the scope of protection of the present application.

[0047] The purpose of the present application is to provide an aluminum alloy cylinder additive and subtractive composite manufacturing method, system and equipment to solve the problems of low printing forming precision and low manufacturing efficiency.

[0048] In order to make the above-mentioned purposes, characteristics and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0049] Figure 1 And Figure 4 An exemplary flow of the above-mentioned aluminum alloy cylinder additive and subtractive composite manufacturing method is shown. Each step will be described in detail below.

[0050] Step 1: Obtain a three-dimensional data model of a ribbed plate aluminum alloy cylinder component;

[0051] In one example, the ribbed plate aluminum alloy cylinder component includes an outer ribbed plate component and / or an inner ribbed plate component. Cylinder components in the field of aerospace bear complex axial and radial loads, and it is difficult to meet the design requirements only by the compressive strength of the cylinder itself. The outer ribbed plate component can significantly improve the overall longitudinal stiffness of the cylinder and enhance its bending resistance. The inner ribbed plate component mainly improves the ring and transverse stiffness and enhances the cylinder's compression and wrinkle resistance.

[0052] Step 2: Secondary adjustment of the three-dimensional data model of the ribbed plate aluminum alloy cylinder component to obtain a ribbed plate aluminum alloy cylinder component blank data model;

[0053] Secondary adjustment (secondary design) includes modifying the thickness features and hole features of the three-dimensional data model of the ribbed plate aluminum alloy cylinder component using three-dimensional model design software, and outputting a ribbed plate aluminum alloy cylinder component blank data model.

[0054] The ribbed plate aluminum alloy cylinder component blank data model obtained by secondary design leaves a margin for thin-walled feature areas by reducing the thickness features and eliminating the hole features, which is beneficial to additive forming, facilitates subsequent finishing, and reduces residual stress during printing.

[0055] Specifically, it includes:

[0056] Step 21: Adjust the thickness and holes of the three-dimensional data model of the ribbed plate aluminum alloy cylinder component.

[0057] when the thickness of the three-dimensional data model of the stiffened plate aluminum alloy cylinder component is less than a first threshold value, increasing the thickness to a second threshold value; the first threshold value is less than the second threshold value.

[0058] In one example, the first threshold value can be 4mm, and the second threshold value can be 6-10mm. When the wall thickness of the stiffened plate aluminum alloy cylinder component model is less than 4mm, the wall thickness can be increased to 6-10mm to reduce deformation in the post-processing process.

[0059] Step 3: slicing and layering the stiffened plate aluminum alloy cylinder component blank data model to obtain a plurality of layers of slices;

[0060] Specifically, it includes:

[0061] Step 31: detecting whether the wall plate of the stiffened plate aluminum alloy cylinder component blank data model has a hole;

[0062] Step 32: if there is a hole, deleting the hole data to obtain a stiffened plate aluminum alloy cylinder component blank data model without holes, and then performing slicing and layering processing; to adapt to additive path planning.

[0063] Step 33: if there is no hole, slicing and layering the stiffened plate aluminum alloy cylinder component blank data model. Please refer to Figure 3 .

[0064] Layering parameters; the layering parameters include: layer number, layer thickness, single channel and / or filling parameters;

[0065] The layer thickness includes: average distribution according to the stiffened plate aluminum alloy cylinder component blank data model; uneven distribution according to the stiffened plate aluminum alloy cylinder component blank data model.

[0066] Step 4: planning a robot trajectory according to the surface structure of any one layer of the plurality of layers of slices to obtain a robot additive path planning instruction;

[0067] In one example, the robot trajectory is planned according to the surface structure profile features of any one layer of the plurality of layers of slices, and finally outputs G code instructions (additive path planning instructions) readable and executable by the robot.

[0068] After slicing the stiffened plate aluminum alloy cylinder component blank data model in the additive direction, a group of slice body structures of the stiffened plate aluminum alloy cylinder component blank data model is obtained, according to the profile features of each slice body structure, the printing path of the robot is planned and controlled, the printing process is accurately controlled, and the quality controllable blank is printed out.

[0069] According to the surface structure of the data model of the aluminum alloy cylinder component with a ribbed plate, a robot trajectory planning is performed to obtain a robot subtractive path planning instruction;

[0070] According to the surface structure of the data model of the aluminum alloy cylinder component with a ribbed plate, a robot trajectory planning is performed, first, the hole features and the boss feature region of the ribbed plate are analyzed, the feature parameters of the hole and the boss are confirmed, at least including the diameter and depth of the hole, the height and length-width size of the boss, according to the confirmed feature parameters, a robot subtractive path planning instruction is designed, at least including determining the type and size of the cutting tool, the cutting path, the cutting depth parameters, according to the robot subtractive path planning instruction, the parameters of each step of subtractive machining are converted into code instructions that can be understood and executed by the tool, at least including setting the cutting point, cutting speed, tool feed speed, etc.

[0071] The robot subtractive path planning instruction at least includes: subtractive speed parameters, tool feed parameters and subtractive depth parameters.

[0072] Part of the code is as follows:

[0073] First, define the tool parameters;

[0074] T1 D10 (define tool 1, diameter 10mm);

[0075] Then program the profile rough machining of the boss region;

[0076] G00 X20 Y50 (quickly position to the upper left corner of the boss) ;

[0077] G01 Z-2 F100 (cut in 2mm at a speed of 100mm / min) ;

[0078] G01 X40 Y70 F800 (profile machining at a speed of 800mm / min);

[0079] G00 Z2 (quick tool withdrawal);

[0080] Then program the machining of the hole;

[0081] G00 X60 Y40 (quickly position to the center of the hole) ;

[0082] G01 Z-8 F100 (cut in 8mm at a speed of 100mm / min) ;

[0083] G02 X60 Y40 R10 (clockwise interpolation of a hole with a radius of 10mm) ;

[0084] G01 Z2 (quick tool withdrawal);

[0085] Step 5: Obtain the additive and subtractive composite manufacturing instructions for the ribbed plate aluminum alloy cylinder component based on the robot additive path planning instructions and the robot subtractive path planning instructions;

[0086] The additive and subtractive composite manufacturing instructions for the ribbed plate aluminum alloy cylinder component execution process includes:

[0087] The robot additive path planning instructions and the robot subtractive path planning instructions work alternately until the ribbed plate aluminum alloy cylinder component is obtained.

[0088] Step 6: Perform additive and subtractive composite manufacturing on the ribbed plate aluminum alloy cylinder component according to the additive and subtractive composite manufacturing instructions for the ribbed plate aluminum alloy cylinder component to obtain the ribbed plate aluminum alloy cylinder component.

[0089] In one example, in the additive and subtractive composite manufacturing process described above, the core is to reasonably arrange the sequence and number of additive printing and subtractive processing procedures, and make them alternate, and the number of two procedures is from the end of the entire blank to the end of the additive and subtractive. Please refer to Figure 4 , specifically including:

[0090] Use the G code instructions obtained in step 4 that can be read and executed by the robot to perform additive segmented printing of the blank, and the printing height of each segment needs to cover the rib plate feature of the ribbed plate aluminum alloy cylinder component model.

[0091] After additive printing of the first segment of the blank, use the subtractive tool instructions obtained in step 4 to perform subtractive processing to complete the rib plate feature processing of the first segment of the blank, and complete the first round of additive and subtractive manufacturing.

[0092] Based on the first segment of the blank after completing the first round of additive and subtractive manufacturing, perform the second round of additive and subtractive manufacturing in the additive direction until the entire blank additive and subtractive manufacturing is completed.

[0093] Finally, perform blank final state finishing on the entire blank to restore the thickness feature and hole feature of the ribbed plate aluminum alloy cylinder component, and complete the manufacturing of the ribbed plate aluminum alloy cylinder component.

[0094] By alternating between additive and subtractive multiple times, the advantages of the two processes can be fully utilized, and the model size and features of the ribbed plate aluminum alloy cylinder component can be gradually approached, improving manufacturing efficiency and quality.

[0095] To sum up, in the embodiment of the present application, the three-dimensional data model of the aluminum alloy cylinder component with a ribbed plate is secondarily adjusted to obtain an aluminum alloy cylinder component with a ribbed plate blank data model; a plurality of layers of slices are obtained by slicing and layering processing; a manipulator additive path planning instruction is obtained by planning a manipulator trajectory according to the surface structure of any one layer of the plurality of layers of slices; a manipulator subtractive path planning instruction is obtained according to the surface structure of the aluminum alloy cylinder component with a ribbed plate blank data model; an additive and subtractive composite manufacturing instruction of the aluminum alloy cylinder component with a ribbed plate is obtained; and the aluminum alloy cylinder component with a ribbed plate is obtained.

The high efficiency of additive manufacturing is achieved, and precise machining is also achieved by subtractive manufacturing. Compared with single additive or subtractive method, higher manufacturing efficiency and better forming quality can be achieved.

[0096] In the embodiment of the present application, the original product design model of the cylinder component with a ribbed plate is secondarily designed and optimized to generate a product blank model convenient for printing. The product blank model is sliced, a printing path is planned according to the structure of each layer, a manipulator additive path instruction is generated, material stacking is accurately controlled, and a blank with controllable printing forming quality is printed. For the key ribbed plate structure of the blank model, a subtractive machining program is compiled, a tool and a path are selected, and numerical control instruction codes are outputted to accurately realize subtractive forming. The additive and subtractive manufacturing is alternately arranged, and the order of multiple printing and simplification is arranged to gradually achieve the design target. The additive manufacturing is adopted first, and the manufacturing of the precision component is completed through the processes of printing, first-round subtractive manufacturing, second-round printing, final-state subtractive manufacturing and the like.

[0097] The above method organically combines the advantages of additive and subtractive manufacturing, realizes the efficient and accurate manufacturing of the complex ribbed plate aluminum alloy cylinder component through the steps of secondary design of the model, path planning and alternate forming.
