研究目的
Investigating the effect of laser texturing on the cutting performance and anti-adhesive properties of textured single-point polycrystalline diamond (PCD) cutting tools in machining Aluminium 6082 alloys.
研究成果
Laser texturing of PCD cutting tools can significantly improve their cutting performance and anti-adhesive properties in dry machining of Aluminium 6082 alloys. Textured tools with grooves perpendicular to the chip flow direction reduced cutting forces by 23% and improved surface quality by 11.8%, making them suitable for finishing applications. Tools with grooves parallel to the chip flow direction reduced adhesion by 59.36% and friction coefficient by 14.28%, making them suitable for roughing operations. Laser manufacturing offers a flexible approach to tailor the geometrical and wear properties of PCD tools for specific applications.
研究不足
The study focused on dry cutting conditions and specific texture designs on PCD tools. The effects of different cooling methods or other texture geometries were not explored. The research also did not investigate the long-term wear behavior of textured tools under industrial conditions.
1:Experimental Design and Method Selection:
The study involved laser micro/nano processing of PCD cutting tools to create different texture designs on the rake face. The effect of these textures on cutting performance was evaluated through turning tests under dry cutting conditions.
2:Sample Selection and Data Sources:
Commercially available PCD cutting tool inserts and Aluminium 6082 alloy cylinders were used. Cutting forces were monitored using a dynamometer connected to charge amplifiers and a data acquisition board.
3:List of Experimental Equipment and Materials:
A 70-W Innolas MMS single mode SPI fibre laser, CNC translation stage, 3D white light interferometer, SEM, EDX, Haas TL-1 CNC lathe, Kistler Kiag Swiss 9257A dynamometer, Kistler 5015 charge amplifiers, Picoscope PC Oscilloscope.
4:Experimental Procedures and Operational Workflow:
Laser processing parameters were optimized to achieve desired groove geometries. Turning tests were conducted under dry conditions, with cutting forces monitored and analyzed. Tool wear and workpiece surface roughness were measured at regular intervals.
5:Data Analysis Methods:
Cutting forces were processed to calculate friction coefficients. Surface roughness and tool wear were analyzed using white light interferometry and SEM/EDX.
