“…The most affecting parameters of drilling are the spindle speed, drill angle and feed rate. 13 The machining behavior of polymer-reinforced composites using different drill bits was studied by Alpay Tamer Erturk. While drilling with HSS Co and HSS TiN, narrow, impacted delamination areas were produced, drilling with CrV produce large, affected delamination areas.…”

Natural fiber composites are gaining interest in many industries, particularly the automotive and aerospace industries. One of the critical secondary activities required to produce a near‐perfectly shaped product is machining. The majority of product components had to be assembled before they could be used. This article reviews the various conventional and non‐conventional machining processes and its influential parameters investigated by various researchers. Non‐traditional machining is now proving to be a better choice than traditional machining. Non‐traditional machining has several advantages, including the absence of thrust force, chatter or vibration, minimal tool wear, and lower frictional heat. Delamination is the major issue occurring in the conventional machining processes like drilling. Researchers are more focused on the non‐conventional machining processes like abrasive water jet machining. Joining of natural fiber reinforced composites is another aspect discussed in this article. Adhesive joining is the most preferable joining method in the natural composites. The joining technique is also influenced by the intricacy of the materials to be bonded. Microwave joining and induction joining processes are the new methods of natural composites joining. This review also covers the various joining processes in the natural reinforced composite materials.

“…Recent studies reveal that the aerospace industry has rejected approximately 60% of drilled composites due to damage introduction, such as drilling-induced delamination [13]. Delamination, which manifests as interlaminar cracking between the fiber reinforcement and the polymer matrix, leads to a reduction in both stiffness and strength and is the most prevalent defect in CFRP drilling [14].…”

Among the types of composite materials, those with thermoplastic matrices have gained importance due to their potential for recycling, lower manufacturing costs, and exceptional impact resistance. However, the machining process of composite materials differs significantly from that used for metals due to their non-homogeneous and anisotropic nature, making the process much more complex and challenging. Moreover, in many cases, the fibers used as reinforcement are highly abrasive, which significantly affects the machining process. Among structural thermoplastic composites, those based on polyetherimide (PEI) matrix show excellent potential for applications in structures with high-performance requirements. This study aims to determine the best drilling parameters to introduce open-hole in specimens of PEI reinforced with continuous carbon fibers (CF) with a minimum delamination. To achieve this, four different cutting tools with different materials and geometries (carbide tool 118°, carbide tool 140°, diamond tool 90°, and carbide tool with two-point angles 90° and 118°) were tested, along with three rotational speeds (4000, 6000, and 8000 rpm) combined with three distinct feed rates (0.025, 0.038, and 0.050 mm/rev) using a full factorial experimental design. A statistical analysis of variance and Tukey’s test were applied to determine the influence of the parameters and to identify the best machining parameters as well as those most suitable for minimizing delamination. The obtained results showed that the damage in the entrance of the hole is influenced by the rotation and geometry of tools, which are bigger for higher rotation, and also by the point angle of the tool, with the 140°-point angle showing less damage than the 118°-point angle. For the exit of the hole, the only variable that directly influenced the outcome was the tool type. The results show that the diamond tool for hole entry/exit has superior finishing. The delamination results at the entrance and exit of the hole indicate that the best drilling parameters are rotation of 4000 rpm, diamond cutting tool with a point angle of 90°, in any of the conditions tested.
