Embodiment 1
[0050] According to the composition of the laminated material, determine the thickness of the workpiece material and the aperture range: the double-layered laminated material is composed of the upper layer of CFRP composite material and the lower layer of titanium alloy, wherein the thickness of the titanium alloy material layer ranges from 5-10mm, and the thickness of the CFRP composite material layer is titanium alloy 2 times the thickness of the layer, the diameter range of the machining hole is 10-20mm, and the ratio of the hole diameter to the tool diameter is 1.5.
[0051] Using a traditional end mill, combined with the helical milling hole end effector under the industrial robot platform, the hole making process of double-layer laminated materials is implemented. The helical milling hole end effector used in the present invention is the prior art, which generally includes a tool The rotation unit, the tool revolution unit, the tool radial offset unit, the axial feed unit...
Embodiment 2
[0062] According to the composition of laminated materials, the thickness and aperture range of workpiece materials are determined: sandwich laminated materials are composed of upper layer CFRP composite material, middle layer titanium alloy and lower layer CFRP composite material. Among them, the thickness range of the titanium alloy material layer is 5-7mm, and the thickness of the CFRP composite material layer is twice the thickness of the titanium alloy layer. The diameter range of the machined hole is 15-30mm, and the ratio of hole diameter to tool diameter is 1.3.
[0063] Using a traditional end mill, combined with the helical milling hole end effector under the platform of the industrial numerical control machine tool to implement the hole making process to the sandwich laminated material, the helical milling hole end effector used in the present invention is the prior art, which generally includes The tool rotation unit, the tool revolution unit, the tool radial offse...
