<p>In the economical CNC lathe, the slender shaft of 6061 aluminum alloy is prone to deformation, bending and chatter. Therefore, we have developed a comprehensive strategy that combines cutting force strain analysis, tool geometry angle selection, adjustment of tool center height, optimization of cutting three elements, and compensatory cross-cutting sequence research. Real-time strain measurement connects the operating parameters with the workpiece deformation, thus achieving predictive parameter selection. The experimental results show that the tool width is reduced by 26 %, the peak strain is reduced by 44 %, the straightness is increased by 33 %, the cylindricity is increased by 92 %, and the surface roughness is significantly reduced.

摘要

In the economical CNC lathe, the slender shaft of 6061 aluminum alloy is prone to deformation, bending and chatter. Therefore, we have developed a comprehensive strategy that combines cutting force strain analysis, tool geometry angle selection, adjustment of tool center height, optimization of cutting three elements, and compensatory cross-cutting sequence research. Real-time strain measurement connects the operating parameters with the workpiece deformation, thus achieving predictive parameter selection. The experimental results show that the tool width is reduced by 26 %, the peak strain is reduced by 44 %, the straightness is increased by 33 %, the cylindricity is increased by 92 %, and the surface roughness is significantly reduced. This method provides a practical way for small and medium-sized enterprises to realize the production of precision slender shaft without high-end equipment.
