12 millimeter or =0.
When 008 millimeter, can achieve the very good imitate result that gets power with the process about cutting bits to form. When the internal stress that analyses workpiece brim area, the flexibility of the material in needing to note cutting imitate procedure especially - plasticity is characteristic. Further imitate analysis is after the imitate that cuts type grinding course squarely. Bear of the machinery on purify workpiece and thermic load, the contact between cancel cutting tool and workpiece, make component refrigeration comes environmental temperature. After this, what withhold inside component is leftover stress and internal stress. What still need to assure experimental data and imitate result here is consistent. Use finite yuan of method is OK more thorough to machining the temperature in the process to produce mechanism to undertake analysis research, and experimental method cannot get these data. Graph the 4 temperature simulation that revealed use cutting tool to cut material of C45E of the cutting below parameter of type grinding craft in different right angle. Highest area gives temperature to pour a circle on same cutting area now generally speaking lesser (R β =0.
01 millimeter) , and cutting ply is bigger (H=0.
02 millimeter) place. Increase gradually as β of R of coefficient of proportionality, temperature is highest area will come from cutting face move the surface (graph 4, the graph reachs right figure in) . Graph the temperature circumstance that blade of 4 different cutting pours a circle to fall passes above the β of positional parameter R that these results can discover apogee of the temperature in the process is relevant. As R β - the accretion of H coefficient of proportionality, more quantity of heat will be passed to workpiece, and the quantity of heat that cuts bits to take away is fewer. Because the size of this cutting tool and form can are opposite,the circumstance brings to bear on influence, adjust then the thermic load that gets on cutting tool. In cutting tool place of development phase cutting tool suffers bear general to decorate the influence with very large generation to the geometry of cutting tool. Finite yuan of auxiliary tool that imitate can regard a kind of effective as, avoid to cost giant experiment to be able to get the case of thermic load and mechanical bear. Graph the bear position that place of the cutting tool below the 5 cases gnawing an edge that showed different in good car process figure accepts. Imitate result makes clear: The old young general that bites an edge affects the stability of cutting tool greatly, and the mechanical negative charge that the geometrical appearance of outside face can drop cutting tool to get. Graph the 3 dimension imitate of process of milling of Nextpage of imitate of bear of cutting tool of 5 horniness turning for have the aid of finite yuan imitate method rebuilds milling process, need builds the 3 dimension model of workpiece and cutting tool above all. Finite yuan of software is medium differentiate automatically reseau function makes the user can undertake differentiating according to special demand. Of milling process build a model to be able to use Deform 3D software to undertake. Graph on 6 indication fixed cutting tool, cutting tool and the part that workpiece contacts undertook more careful reseau differentiates. The model is built as rigid system in the cutting tool in this example. According to the rate that has defined and directional drive workpiece. The contact of workpiece and cutting tool undertook more careful reseau differentiates, such making that the slope of stress and temperature is more dispersive. This is the premise condition that describes cutting force and imitate cutting process better. Calculative result can show detail, use at evaluating output variable. Pursue 6 times the temperature after the graph showed cutting the 3rd times distributings. Graph the high speed milling that the simulator that the above paragraphs of 3 dimension imitate of 6 milling process introduces can use at aluminous simple stuff. Process parameter can be divided for cutting speed, feed and dimension of milling head geometry, the purpose is the cutting force inside area of analytic workpiece brim and stress. Graph 7 showed the process bears the relationship between force and feed. Can discover with the look getting power that gets through the experiment both result is more consistent quite. The change of the in sufferring force to check imitate cutting rate that also can get in experiment of have the aid of additionally and cutting angle. Graph the feed in 7 milling treatment is more thorough to sufferring the effect of force the place on put together of process of geographical solution cutting narrates: Have the aid of of investigation data specification is finite yuan the method can rebuild cutting process. Among them, 2 dimension imitate can be used at analysing right angle to cut type grinding course, and 3 dimension imitate can be used at analysing milling process. Consider to be compared with the experiment, imitate method can analyse thermic load of susceptive of cutting tool place and mechanical bear alone already, OK still analyse further from the angle of time, space. In still can analysing a test cannot the domain of dug, such as temperature distributings. First-rate output is data of test of have the aid of as a result will check imitate result, contrast for example the process suffers force to perhaps cut bits form. Use experimental result to also can check simulative result conversely. Imitate method is OK still and accurate the influence of the joint action that forecasts all sorts of negative charge on cutting cutting tool and workpiece, to cutting the process also will have a more thorough understanding. Current imitate job used coating cutting tool. Result of imitate of have the aid of can analyse the effect of workpiece parameter, such as heat conducts function and heat to conduct correlation coefficient. CNC Milling
