Přidat tag | Shrnutí: | The present work contains the characteristics mechanical, physical, chemical and thermal treatments, to know the degree of composition of the materials that allow it to reach high hardness to AISI P20 steel; Therefore, the different materials used in flat milling for high hardness are exposed, with a focus on CAD/CAM software, together with this, the Taguchi methods and the Anova analysis used in the experiment are stable. Subsequently, the factors, the working machinery and the measuring instruments are established for the execution of the thermal treatment of quenching and tempering; it then defines the tool-specific material, technical data, and cutting fluid that is applied to determine the levels of each factor and obtain the orthogonal matrix of 27 machining strategies. The following is the experimental design in the CAD/CAM software, the definition of the Inventor HSM program and the programming of the strategies; after the mechanization, the measurement of the hardness is carried out before and after to know the result of variation that is of +2,07%. Then we proceed to measure the roughness of the faces, resulting in 2D and 3D graphics that help to establish a statistical regression equation to predict the roughness. Finally the Anova method determines the cutting speed factor with greater influence on the surface finish of 66,19% and evaluating the results with the null and alternative hypothesis test an improved strategy of cutting speed is obtained = 25 m/min, Advance = 101,461 m/min, trajectory = ZIG-ZAG and radial depth = 1,29 mm, which allows optimum roughness of 0,11 μm, which is verified within the calculated tolerance range. |
