“…Attempts are being made to link the physical parameters of the lubricant, such as film thickness and viscosity, the surface roughness of surfaces in contact, the process parameters (contact pressure, sliding speed), and the elasto-plastic behavior of the interacting asperities with the amount of frictional resistance [28][29][30]. Mixed and boundary lubrication models of contact allow us to determine frictional resistances by considering the effect of load, lubricant properties and changes in sliding speed [31,32]. More complex thermo-mechanical phenomena should be taken into account during friction welding processes [33,34], which are currently of wide interest in the aerospace industry.…”

The concept of Industry 4.0 is defined as a common term for technology and the concept of new digital tools to optimize the manufacturing process. Within this framework of modular smart factories, cyber-physical systems monitor physical processes creating a virtual copy of the physical world and making decentralized decisions. This article presents a review of the literature on virtual methods of computer-aided manufacturing processes. Numerical modeling is used to predict stress and temperature distribution, springback, material flow, and prediction of phase transformations, as well as for determining forming forces and the locations of potential wrinkling and cracking. The scope of the review has been limited to the last ten years, with an emphasis on the current state of knowledge. Intelligent production driven by the concept of Industry 4.0 and the demand for high-quality equipment in the aerospace and automotive industries forces the development of manufacturing techniques to progress towards intelligent manufacturing and ecological production. Multi-scale approaches that tend to move from macro- to micro- parameters become very important in numerical optimization programs. The software requirements for optimizing a fully coupled thermo-mechanical microstructure then increase rapidly. The highly advanced simulation programs based on our knowledge of physical and mechanical phenomena occurring in non-homogeneous materials allow a significant acceleration of the introduction of new products and the optimization of existing processes.

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.

Nowadays, the utilization of natural fiber reinforced composite has increased frequently. These natural fibers have significant features like low cost, renewable, and, more importantly, biodegradable in nature, making them to be utilized for various industrial sectors. However, the massive demand for natural fiber reinforced composites (NFRC), forces them to be machined and operated, which is required for countless areas in multiple industries like automotive, marine, aerospace and constructions. But before obtaining the final shape of any specimen, this specimen should come across numerous machining processes to get the desired shape and structure. Therefore, the present review paper focused on the various aspects during conventional and unconventional machining of the NFRC. It covers the work by exploring the influence of all input variables on the outcome produced after machining the NFRC. Various methodologies and tools are also discussed in this article for reducing the machining defects. The machining of the NFRC is found as a challenging task due to insufficient interlocking between the matrix and fibers, and minimum knowledge in machining characteristics and appropriate input parameters. Thus, this review is trying to assist the readers to grasp a basic understanding and information during the machining of the NFRC in every aspect.
