Повний текст джерелаThe new analytical model, which is developed to predict the distributions of the stress, the strain, the strain rate, and the temperature in the primary shear zone, is based on conceptual considerations, as well as characterization of the plastic deformation process through comprehensive FEM simulations.
Orthogonal cutting experiments at room temperature and preheated conditions were carefully designed. While the cutting tests at room temperature provided the constitutive data encountered in the primary shear zone, the preheated cutting tests were designed to capture the material behavior at the high level of temperature and strain encountered in the secondary shear zone. In these preheated cutting tests, a laser beam was employed. Quasi-static tests were also utilized to identify some of the coefficients in the constitutive equations, in order to improve the convergence to a unique solution for the constitutive law.
Evaluation criteria were developed to assess the performance of constitutive equations. Based on the developed methodology and the evaluation criteria, a new constitutive equation for Inconel 718 has been proposed. This constitutive equation was further validated by Split Hopkinson Pressure Bar (SHPB) tests and cutting tests in conjunction with FEM simulations. The SHPB test data show an excellent agreement with the proposed material model. The cutting tests and the FEM simulation results also proved the validity of the proposed material constitutive law.

Resumo: Normalmente, a utilização de aços ferramenta endurecidos, juntamente com as formas complexas típicas das peças utilizadas na área de moldes e matrizes, oferecem dificuldade na usinagem por fresamento, principalmente nas operações de acabamento que exijam o uso de ferramentas longas. A técnica de fresamento HSM (High Speed Machining - usinagem em altas velocidades, ou ainda High Speed Milling - fresamento em altas velocidades) tem se tornado uma alternativa para realizar este tipo de usinagem, reduzindo, ou às vezes até eliminando operações de eletro-erosão e polimento. Tipicamente, as fresas de pastilhas de metal duro intercambiáveis tem sido usadas em operações de desbaste e semi-acabamento, enquanto nas operações de acabamento ou em usinagem de geometrias que exijam ferramentas com pequenos diâmetros ainda predomina o uso de fresas inteiriças. O objetivo principal deste estudo é avaliar a influência de cinco variáveis de processo de fresamento com alta velocidade de corte, sobre o acabamento da superfície usinada. A influência do desgaste das ferramentas sobre o acabamento superficial, ao longo de 400 minutos de usinagem, também foi avaliado, além de uma comparação entre ferramentas inteiriças de metal duro e ferramentas de pastilha intercambiável montada em corpo de metal duro, a fim de avaliar a viabilidade técnica do uso deste segundo tipo de ferramenta, em substituição às tradicionais fresas inteiriças utilizadas em operações de acabamento. Na maioria dos experimentos realizados, pequenos valores de rugosidade foram mantidos, demonstrando que operações de acabamento em aço ABNT H13 IM com dureza de 50 HRC é possível com vida longa de ferramenta, mesmo utilizando-se valor de 500 m/min para velocidade de corte. Além disto, a análise da influência das variáveis de processo utilizadas neste trabalho mostrou que é possível, sob algumas condições, utilizar tanto ferramentas inteiriças, quanto de pastilha intercambiável montada em corpo de metal duro em operações de acabamento
Abstract: Typically, the use of hardened tool steels, along with complex shapes typical of the parts used in the field of molds and dies, offer difficulty in machining by milling, mainly in finishing operations that demand the use of long tool. The HSM (High Speed Machining or High Speed Milling) has become a possible alternative for making this type of machining, reducing, or sometimes eliminating electric discharge machining and polishing operations. Usually, indexable carbide insert mills has been used for roughing and semi-finishing, while in finishing operations or when the machining geometries that require tools with small diameters the integral tools are used yet. The main objective of this study is to evaluate the influence of five process variables, with high cutting speed, on the finish of the machined surface. The influence of tool wear on surface finish through 400 minutes of milling was also evaluated, as well as a comparison between integral carbide mills and indexable insert mounted at cemented carbide toolholder endmills, in order to evaluate the technical feasibility of using this second type of tool, replacing the traditional integral carbide endmills used in finishing operations. In most experiments, small roughness values were maintained, showing that finishing operations on AISI H13 IM with a hardness of 50 HRC is possible with long tool life, even using the cutting speed of 500 m/min. Furthermore, the analysis of the influence of process variables used in this study showed that is possible, under some conditions, the use either integral carbide tools, or indexable insert mounted at cemented carbide toolholder endmills on finishing operations

Resumo: O principal objetivo deste trabalho é caracterizar a qualidade da superfície gerada no processo de fresamento em acabamento, com fresas de topo esférico, do aço para trabalho a frio ABNT D2, endurecido. Utilizou-se o método do planejamento fatorial e as variáveis de influência foram às condições de contato entre a ferramenta e a superfície usinada, os parâmetros de corte e o desgaste de flanco da ferramenta de corte (VB). O aumento da velocidade de corte muda o mecanismo de formação do cavaco, causando a diminuição da razão entre o aumento dos esforços de usinagem e da deflexão da ferramenta de corte em relação ao aumento da velocidade de corte, decorrente da mudança na distribuição de temperatura entre a ferramenta de corte, a peça e o cavaco. Há interação entre a velocidade de corte, o sobrematerial e o avanço, em relação à deformação, encruamento e conseqüente endurecimento da superfície usinada. O desgaste da ferramenta de corte tem significativa influência na integridade da superfície gerada. A velocidade de corte e o avanço por dente influenciam na segmentação do cavaco
Abstract: The main goal of this investigation is to characterize the quality of the generated surface, in the process of finishing milling, of the hardened steel for cold work ABNT D2. The method of factorial planning was used and the variables of influence were the conditions of contact between the cutting tool and the machined surface, the cutting parameters and the cutting tool wear. The increase of the cutting speed change the mechanism of chip formation, causing the reduction of the ratio of the increase of machining forces and the deflection of the cutting tool in relation to the increase of the cut speed, because of the change in the distribution of temperature between the tool, the part and the chip. There is interaction between cutting speed, feed rate and stock removal, in relation the deformation, strain hardening and consequent hardening of the surface machining. The wear of the cutting tool has significant influence in the integrity of the generated surface. The cutting speed and the feed for tooth influence the segmentation of the chi
