For finishing jobs, the positive inserts always serve as the best option because they have the ability of creating less cutting forces. Therefore, they can easily get away with low cut depths while eliminating vibration at the same time. The DNMG or Diamond 55 degree insert is one of the most well-known roughing inserts. These inserts come with 55 degree included angle and can effectively be used for shaft turning and recessing. They are preferred over the TNMG inserts mainly because they produce less cutting force.

Abstract: In civil engineering, carbon fibre-reinforced polymer (CFRP) composites have emerged as a promising alternative to conventional materials. The article provides a comprehensive overview of the application of CFRP composites in various building structural elements and their characteristics and properties, such as their fatigue and corrosion resistance, stiffness and high strength, and incorporation of temperature factors. The advantages and disadvantages of CFRP composites and the current trends and prospects for CFRP composites in the construction sector are discussed. In addition, the article compares various studies on CFRP composites to shed light on their performance and potential limitations. This paper aims to provide useful information to researchers and practitioners interested in using CFRP composites in civil engineering applications. In addition, the article discusses emerging materials in CFRP, such as nanostructured carbon fibres, hybrid fibre reinforcement, and self-sensing CFRP. Additionally, the paper outlines how CFRP composites promote sustainability by increasing structural durability and longevity.

The main difference lies in the insert shape. DNMG inserts have a rhombic shape, with a 55-degree angle between the two opposite cutting edges. On the other hand, TNMG inserts have a triangular shape, with a 60-degree angle between the two opposite cutting edges.

In conclusion, while DNMG and TNMG inserts share similarities in their usage for metal turning operations, they differ in terms of insert shape, cutting edge configuration, application, chip control, and size. Understanding the differences between these insert types can help machinists select the most suitable insert for their specific turning needs.

DNMG inserts typically have four cutting edges - two primary cutting edges and two secondary cutting edges. The primary cutting edges are located on the longer sides of the rhombic shape, while the secondary cutting edges are on the shorter sides. TNMG inserts, on the other hand, have three cutting edges - one primary cutting edge and two secondary cutting edges. The primary cutting edge is the longest edge of the triangular shape, while the secondary cutting edges are the shorter edges.

DNMG inserts are commonly used for general-purpose turning operations, suitable for both roughing and finishing cuts. They are versatile and can handle a wide range of materials and cutting conditions. TNMG inserts, on the other hand, are primarily used for medium to heavy-duty turning operations. They are designed for roughing applications and are particularly effective in removing larger amounts of material.

When making the choice of turning insert, going for the right insert of required job is just half the battle done. There are also steps like choosing the best chip breaker and grade that also need to be done. Whether you are going for a DNMG insert or a TNMG insert, the very first thing that you need to consider is whether you are simple going for general turning or for finishing or roughing. Here, it is important to note that the negative inserts tend to be the strongest. Thus, they are the most perfect options for general turning and roughing applications. Thatâs because they make way for deep cut depths and higher feed rates because of thickness and strong insert shapes.

Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal.

Due to their different cutting edge configurations, DNMG and TNMG inserts exhibit slight differences in chip control. DNMG inserts tend to produce shorter and more manageable chips, making them suitable for applications where chip control is critical. TNMG inserts, on the other hand, are designed to handle larger chip loads, making them more effective in heavy machining operations.

DNMG and TNMG inserts are available in various sizes to accommodate different lathe tool holders and machine setups. The size designation typically includes information about the insert shape, cutting edge length, and thickness.
