What is the processing order of aluminum alloy cnc? What factors affect the cutting efficiency of aluminum alloy CNC machining?
The arrangement of aluminum alloy cnc processing should be considered according to the structure of the part and the condition of the blank, and the need for positioning and clamping has been considered. The key point is that the rigidity of the workpiece is not destroyed. The sequence should generally be carried out according to the following principles.
(1) The processing of the previous process can not affect the positioning and clamping of the next process, and the processing process of the general machine tool interspersed in the middle should also be considered comprehensively.
(2) Carry out the inner cavity and inner cavity process first, and then perform the outer shape processing process.
(3) The process of processing with the same positioning, clamping method or the same tool is well connected to reduce the number of repeated positioning, the number of tool changes and the number of moving the pressure plate.
(4) For multiple processes performed in the same installation, the process with little damage to the workpiece rigidity should be arranged first.
In the process of aluminum alloy CNC machining, the cutting efficiency has a great influence on the quality of precision parts processing, but the cutting efficiency will be affected by human factors, environmental factors and factors of the machine tool itself. What specific factors have an effect on the cutting efficiency of aluminum alloy CNC machining?
The effect of the cutter on the aluminum alloy cnc processing is like the effect of the wheel on the car. The material used to make the tool must have high high-temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical inertness, good manufacturability (cutting, forging and heat treatment, etc.), and not easy to deform. A good tool can improve the efficiency of machining and the accuracy of the workpiece being cut.
Other factors such as power supply, familiar operation, reasonable materials and other factors will affect the processing of aluminum alloy CNC machining center.
Reasonable cutting amount can improve the efficiency of aluminum alloy CNC machining. When the cutting speed is increased by 10 times and the feed speed is increased by 20 times, far beyond the traditional cutting prohibited area, the cutting mechanism has undergone a fundamental change. The result is: the metal removal rate per unit power is increased by 30% -40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, the cutting heat left on the workpiece is greatly reduced, and the cutting vibration is almost eliminated ; The cutting process has taken an essential leap. According to the current situation of aluminum alloy CNC machining, increasing the feed per tooth increases the productivity and tool life.
