“…Cutting speed and feed are mainly studied [ 9 , 10 , 11 , 12 ], but only a few authors also include depth of cut [ 13 ] since most of them think that its influence on delamination is not as relevant as cutting speed and feed. Fiber orientation angle respect to machining direction is as well evaluated, with the aim of determining orientations to avoid or decrease delamination [ 14 , 15 , 16 ].…”

Delamination is one of the main problems that occur when machining fiber-reinforced composite materials. In this work, Types I and II of delamination are studied separately in edge trimming of basalt fiber reinforced plastic (BFRP). For this purpose, one-dimensional and area delamination parameters are defined. One-dimensional parameters (Wa and Wb) allow to know average fibers length while the analysis of area delamination parameters (Sd) allow to evaluate delamination density. To study delamination, different tests are carried out modifying cutting parameters (cutting speed, feed per tooth and depth of cut) and material characteristics (fiber volume fraction and fiber orientation). Laminates with a lower fiber volume fraction do not present delamination. Attending to one-dimensional parameters it can be concluded that Type II delamination is more important than Type I and that a high depth of cut generates higher values of delamination parameters. An analysis of variance (ANOVA) is performed to study area parameters. Although delamination has a random nature, for each depth of cut, more influence variables in area delamination are firstly, feed per tooth and secondly, cutting speed.

“…That is to say, the conventional cutting tools is usually not the best choice to machining good quality features in CFRPs unless using some certain methods. A effective approach to improve machining quality is that making the single cutting thickness in the reasonable range [8,9]. On the other hand, applying internal coolant holes at speci c position and using minimum quantity lubrication (MQL), the tool wear is also effectively reduced and hole surface quality is greatly improved [10].…”

Carbon fibre reinforced polymer (CFRP) composites are widely used in high-tech industries like the automobile and aerospace sectors, but the wear resistance of tools is one of the most significant restrictions in machining CFRP. In this study, bionic cutting tools based on surface microstructures of blood clams were fabricated to improve the dry cutting performance of CFRP. Three types of bionic cutting tools with different size parameters were applied in dry cutting test. The three-axis cutting forces and the cutting temperature of the processed workpiece were measured. The average friction coefficient between the rake face and the chip was calculated, and the morphology of the tools wear were observed. The results showed that bionic microstructures with appropriate size parameters can extremely improve the cutting performance of CFRP for tool in turning.

“…Respecto a la profundidad de pasada que ha sido mucho menos estudiada, Kim M. [87] afirma que profundidades de pasada pequeñas por debajo de 1 mm, aceleran el desgaste del flanco, debido al aumento de la distancia de fricción sobre la cara de incidencia.…”

“…Recientemente, algunos autores han estudiado el efecto sobre el desgaste de algunas características del material como la orientación de la fibra como Kim M. [87] y Nguyen N. [82]. Ambos comprueban que el mecanizado de materiales compuestos a se realiza por la fractura de las fibras y esto provoca dos tipos de desgaste: el desgaste de la arista o borde de la herramienta y principalmente desgaste en la cara de incidencia o de flanco.…”

“…El desgaste en la cara de incidencia o de flanco causado por la fuerza de fricción con la superficie mecanizada. Kim M. et al [87], concluyen que el desgaste de la herramienta está fuertemente influenciado por la orientación de la fibra. En su trabajo, con una longitud mecanizada de 7 metros, el desgaste de flanco es mucho mayor con una orientación de fibra de 0º, esta orientación coincide con la dirección paralela entre la fibra y la cara de incidencia.…”

Fiber reinforced composites are widely used in diverse fields such as aeronautics and automotive. After their shaping, these materials require machining processes to remove excess material and facilitate joining between parts. Due to the heterogeneous nature and anisotropy of these materials, their behavior when being machined is different from metallic ones. Abrasive fibers trigger fast tool wear and delamination appearance can cause piece reprocessing or discard. Delamination is a defect which induces the separation of composite layers and makes the piece present a frayed appearance on the machined edge because the tool bends the fibers instead of cutting them, in addition to producing surface damage to the piece.
