Embodiment 1
[0050] Determine the thickness and aperture range of the workpiece material according to the composition of the laminated material: the double laminated material is composed of an upper layer of CFRP composite material and a lower layer of titanium alloy. The thickness of the titanium alloy material layer is 5-10mm, and the thickness of the CFRP composite material layer is titanium alloy. 2 times the layer thickness, the diameter of the machining hole is 10-20mm, and the ratio of the hole diameter to the tool diameter is 1.5.
[0051] Using traditional end mills, the spiral milling hole terminal actuator is used under the industrial robot platform to implement the hole-making processing of the double-layer laminated material. The spiral milling hole terminal actuator used in the present invention is an existing technology, which generally includes a tool Rotation unit, tool revolution unit, tool radial offset unit, axial feed unit, etc., can realize the control of various paramete...
Embodiment 2
[0062] According to the composition of the laminated material, determine the thickness of the workpiece material and the range of the pore diameter: the sandwich laminated material is composed of the upper layer of CFRP composite material, the middle layer of titanium alloy and the lower layer of CFRP composite material. Among them, the thickness of the titanium alloy material layer ranges from 5 to 7 mm, and the thickness of the CFRP composite material layer is twice the thickness of the titanium alloy layer. The diameter range of the machining hole is 15-30mm, and the ratio of the hole diameter to the tool diameter is 1.3.
[0063] Using traditional end mills, the spiral milling hole terminal actuator is used under the industrial numerical control machine tool platform to implement the hole-making processing of the sandwich laminated material. The spiral milling hole terminal actuator used in the present invention is an existing technology, which generally includes Tool rotatio...
