In the field of aluminum alloy processing, especially for lightweight and high-strength materials such as honeycomb aluminum, resistance control and machine tool load optimization during cutting are crucial. High cutting resistance not only affects processing efficiency, but may also lead to accelerated tool wear and increased machine tool vibration, thus affecting processing accuracy and workpiece surface quality. Therefore, the key to improving processing performance and economic benefits is to reasonably design and use aluminum alloy tools honeycomb aluminum drill bit to reduce cutting resistance and reduce machine tool load.
First of all, the selection of tool materials is the basis. In aluminum alloy processing, carbide tools are widely used due to their high hardness, high wear resistance and good thermal stability. For the cutting of honeycomb aluminum, the use of carbide tools with coating treatment, such as titanium nitride (TiN) or aluminum titanium nitride (AlTiN) coating, can effectively reduce the friction coefficient between the tool and the workpiece, thereby reducing cutting resistance.
The optimization of tool structure is equally important. Reasonable design of the drill core thickness and drill tip chisel edge shape of the drill bit can not only improve the cutting performance of the drill tip, but also reduce the axial cutting force. For example, by increasing the drill core thickness of the working part of the drill bit and thinning the drill tip chisel edge, the cutting resistance can be reduced while maintaining cutting efficiency.
The selection of cutting parameters has a direct impact on cutting resistance and machine tool load. The reasonable matching of cutting speed, feed rate and cutting depth is the key to reducing cutting resistance. In aluminum alloy processing, the use of higher cutting speeds can generate greater centrifugal force, promote the smooth discharge of chips, and reduce friction and heat accumulation during the cutting process. At the same time, appropriately reducing the feed rate and cutting depth can reduce the contact area between the tool and the workpiece per unit time, thereby reducing cutting resistance.
Cutting fluid plays a role in cooling, lubricating and cleaning in aluminum alloy processing. Selecting a suitable cutting fluid, such as an emulsified anti-friction cutting fluid or a low-viscosity cutting oil, can effectively reduce the friction coefficient and cutting temperature during the cutting process, thereby reducing cutting resistance. The lubricity and cooling performance of cutting fluid are particularly critical to reducing the load of machine tools. It can help reduce tool wear, extend tool life, and thus reduce the burden on machine tools.
The planning of tool paths also has a significant impact on cutting resistance and machine tool load. When processing honeycomb aluminum, sudden changes in direction or emergency stops of the tool on the workpiece should be avoided as much as possible to reduce the impact load of the machine tool. At the same time, the use of layered multiple processing methods or symmetrical processing methods can evenly distribute cutting forces, reduce workpiece deformation and machine tool vibration, and further reduce cutting resistance and machine tool load.
By optimizing tool materials and structures, adjusting cutting parameters, using special cutting fluids, and rationally planning tool paths, the resistance of aluminum alloy tools honeycomb aluminum drill bit during cutting can be significantly reduced, the machine tool load can be reduced, and the processing efficiency and workpiece quality can be improved.
