“…It is found that cutting speed and feed per tooth are important factors affecting the residual stress on the surface [93]. When AISI H13 steel is hard milled by coated cutting tools, the investigated result of in-depth residual stress distribution showed that microstructural changes deeply affect the residual stress and that they have to be accurately taken into account during the process design [94]. Wang et al [95] studied the effects of cutting parameters, cutting fluid, and spindle angle on residual stress during milling of Inconel 718 alloy.…”

It has been proved that surface integrity alteration induced by machining process has a profound influence on the performance of a component. As a widely used processing technology, milling technology can process parts of different quality grades according to the processing conditions. The different cutting conditions will directly affect the surface state of the machined parts (surface texture, surface morphology, surface residual stress, etc.) and affect the final performance of the workpiece. Therefore, it is of great significance to reveal the mapping relationship between working conditions, surface integrity, and parts performance in milling process for the rational selection of cutting conditions. The effects of cutting parameters such as cutting speed, feed speed, cutting depth, and tool wear on the machined surface integrity during milling are emphatically reviewed. At the same time, the relationship between the machined surface integrity and the performance of parts is also revealed. Furthermore, problems that exist in the study of surface integrity and workpiece performance in milling process are pointed out and we also suggest that more research should be conducted in this area in future.

“…In the field of milling of hardened steels, in contrast to others, Zhang and Guo [20] studied the relations between the chip morphology, phase transformation, and oxidation and milling of final finishing milling of these. Also, in different studies carried out on both the same material and powder metallurgy steels, it is observed that now the tension and surface conditions are being studied [6,7,21,22]. Cui et al [23] studied the tool wear occurring during the milling of hardened AISI H13 steel with CBN tips, cutting forces, and chip formation.…”

In this study, surface roughness, tool wear and cutting force have been investigated in milling of Böhler K390 cold work tool steel with coated carbide inserts. Test specimens were tempered at different three temperatures after quenching. Milling tests were performed at four different cutting speeds and feed rates. Surface roughness Ra and cutting forces were measured for further evaluation. Besides, images of cutting inserts were taken from electron microscope (SEM) for determining the wear types and mechanism. Analysis of variance (ANOVA) was used to determine the most influencing cutting parameters on the milling performance. According to the experimental results, they have been low cutting force, value of Ra (0.031 µm), and minimum tool wear in a specimen tempered at high temperature. Due to intermitted cutting, pressure and high temperature, there are more chipping and attrition on cutting insert. Surface qualities of milling surfaces were obtained by grinding operations. According to the analysis of variance feed rate levels, the most effective parameters are Ra and Fm.

“…Estudos específicos relacionados aos fatores aqui estudados da maneira como foram agrupados não são comuns. De um modo geral encontra-se estudos direcionados ao processo de torneamento, [13 e 18], fresamento, [19,20,21,22], furação, [23], entre outros. Uma boa fonte de literaturas relacionadas ao tema pode ser encontrada em trabalhos que buscam predizer o comportamento da tensão residual para os diversos processos de usinagem.…”

RESUMO Dentre os diversos processos de fabricação destaca-se a usinagem. Dentre suas operações tem-se a de fresamento que, confere características à superfície gerada que influem no desempenho do componente ou peça em trabalho. Uma destas características é a tensão residual induzida pelo processo. Dependendo de seu caráter, trativo ou compressivo, intensidade e profundidade afetada, pode ser benéfica ou deletéria. Neste trabalho foi investigado o efeito dos parâmetros, velocidade de corte, ângulo de posição da fresa e condição do material, aço ABNT 4340, obtida pelos tratamentos térmicos de recozimento e normalização, sobre a tensão residual induzida na superfície. Para isto, foi realizado um planejamento fatorial 2x3x2 com três réplicas. As tensões residuais foram medidas pelo método do furo central. Os resultados obtidos foram organizados e analisados sob os aspectos qualitativo, perfil ao longo da profundidade, e quantitativo. Os resultados indicaram que o aumento da velocidade de corte fez com que a tensão residual induzida na superfície fosse compressiva ou menos trativa. A variação do ângulo de posição exerceu efeito discreto sobre a tensão residual. O material fresado na condição normalizado apresentou tensões residuais compressivas enquanto que na condição recozido, trativas. Para avaliação do aspecto quantitativo foi realizada uma análise de variância para os dados referentes às tensões residuais induzidas na profundidade de 17µm abaixo da superfície. O resultado demonstrou que os dados seguem uma distribuição normal e que os fatores velocidade de corte e tratamento térmico se mostraram significativos ao nível de confiança de 95% tanto isoladamente quanto nas interações de segunda e terceira ordem.
