Tóm tắt

Cáp sợi carbon–polymer (CFRP) và các cụm hợp kim titan đóng vai trò quan trọng trong lĩnh vực hàng không để cải thiện tính chất cơ học của các thành phần lắp ráp. Khoan hỗ trợ rung tần số thấp (LFVAD) có thể thực hiện đặc điểm tiếp xúc và tách biệt theo chu kỳ giữa công cụ và chi tiết gia công, do đó có tiềm năng cao trong việc điều chỉnh khả năng gia công của các cụm CFRP/Ti. Trong nghiên cứu này, hai loại công cụ khoan (công cụ kim cương đa tinh thể (PCD) và công cụ phủ kim cương) được áp dụng, và hành vi mài mòn của công cụ được đánh giá kỹ lưỡng trong quá trình khoan các cụm CFRP/Ti. Đồng thời, các ảnh hưởng cụ thể của mài mòn công cụ đối với hiệu suất khoan cũng được phân tích một cách toàn diện dưới chế độ LFVAD với bôi trơn lượng tối thiểu (MQL). Kết quả cho thấy có sự bám dính titan trên cả hai công cụ khoan. Trong khi đó, gãy cạnh là chế độ mài mòn chính chiếm ưu thế đối với công cụ PCD, và bong tróc lớp phủ là chế độ mài mòn chính đối với công cụ phủ kim cương, với ít bám dính titan hơn. Ngoài ra, với số lượng lỗ khoan tăng lên, công cụ phủ kim cương thể hiện hiệu suất khoan tốt hơn với lực cắt thấp hơn, chất lượng lỗ tốt hơn và số lượng lỗ khoan nhiều hơn. Những phát hiện của nghiên cứu này có thể góp phần cung cấp hướng dẫn trong việc lựa chọn công cụ tối ưu trong quá trình khoan CFRP/Ti bằng hỗ trợ rung tần số thấp với MQL.
