“…Therefore, it is significant to investigate the machinability of stainless steel for optimizing the machining process. Ahmed et al [7] proposed that the reasonable control of built-up edge (BUE) could effectively improve the machining surface quality of stainless steel. Both Özbek et al [8] and Patil et al [9] adopted cryogenically treated cutting tools to turn austenitic stainless steel.…”

The application of AISI 304 austenitic stainless steel in various industrial fields has been greatly increased, but poor machinability classifies AISI 304 as a difficult-to-cut material. This study investigated the tool wear, surface topography, and optimization of cutting parameters during the machining of an AISI 304 flange component. The machining features of the AISI 304 flange included both cylindrical and end-face surfaces. Experimental results indicated that an increased cutting speed or feed aggravated tool wear and affected the machined surface roughness and surface defects simultaneously. The generation and distribution of surface defects was random. Tearing surface was the major defect in cylinder turning, while side flow was more severe in face turning. The response surface method (RSM) was applied to explore the influence of cutting parameters (e.g., cutting speed, feed, and depth of cut) on surface roughness, material removal rate (MRR), and specific cutting energy (SCE). The quadratic model of each response variable was proposed by analyzing the experimental data. The optimization of the cutting parameters was performed with a surface roughness less than the required value, the maximum MRR, and the minimum SCE as the objective. It was found that the desirable cutting parameters were v = 120 m/min, f = 0.18 mm/rev, and ap = 0.42 mm for the AISI 304 flange to be machined.

“…A usinagem de materiais de baixa condutibilidade térmica, como a dos aços inoxidáveis austeníticos, leva a altas temperaturas localizadas e conduz a alta aderência do material da peça na ferramenta de corte, resultando na formação da aresta postiça de corte [8,9]. Este material deformado adere firmemente na interface do cavaco/ferramenta e impede que o material da peça deslize sobre a ferramenta [9, 10,11].…”

“…A formação dessa aresta é um processo instável e é capaz de causar danos na superfície da ferramenta, podendo levar a sua quebra [8,9]. No entanto, às vezes, essa aresta postiça impede o deslizamento na interface, protegendo a ferramenta contra desgaste [10]. Um exemplo da presença de uma aresta postiça de corte está representado na Figura 2 [10].…”

A usinagem é uma operação bastante comum em processos industriais, mas que necessita de cuidado e controle dos seus parâmetros, sobretudo quando se trata dos aços inoxidáveis austeníticos. O objetivo deste trabalho é mapear a literatura disponível sobre a usinagem deste material mostrando um breve resumo sobre alguns dos resultados encontrados. A base de dados utilizada foi a de artigos publicados na plataforma ScienceDirect. Os resultados comprovaram o grande desafio na usinagem do material e revelam que apenas 8,3% dos artigos publicados sobre usinagem de aços inoxidável são da família dos austeníticos. O maior desafio é superar a baixa condutibilidade térmica, característica deste material, que causa a formação de aresta postiça de corte.

Imaging techniques have been widely implemented to study the dynamics of chip formation. They can offer a direct method and a full field measurement of the cutting process, providing kinematic information of the chip formation process. In this article, the state of the art of the imaging techniques reported in the literature has been summarized and analyzed. The imaging techniques have been applied to study the chip formation mechanism, friction behavior, strain/strain rate, and stress fields. Furthermore, the study of surface integrity has been advanced by deriving the thermo‐mechanical loading, subsurface deformation, and material constitutive model from the imaging technique. Finally, achievements in the area of imaging techniques have been summarized, followed by future directions for their application in the study of surface integrity.
