  • It is unavoidable that the tools you use in the CNC processing process will become worn over time when working with aluminum alloy die castings and mold blanks because of the nature of the material. It is only when a tool has become excessively worn that it is possible to dispose of it completely and permanently. In this way, it is possible to increase tool life while simultaneously lowering the cost of aluminum alloy die casting in a covert manner. This method of manufacturing is particularly advantageous in the automotive industry. To increase the service life of the cutting tools while also improving machining efficiency, the coating technology will be implemented for the current cutting tools. In this article, we will discuss several factors that contribute to tool wear in aluminum die casting operations, as well as strategies for reducing tool wear in these processes.

    Wearable tooling is available in a variety of different designs.

    During the course of a construction project, it is common to encounter the following types of tool wear:

    So far, there have been seven separate instances of catastrophic failures.

    The following factors must be taken into consideration in order to reduce tool wear:

    Hot air and friction are examples of energy manifestations that occur during the metal cutting process for aluminum casting or mold blanks. Hot air and friction are manifestations of energy that occur during the metal cutting process for aluminum die casting parts or mold blanks. The rapid movement of chips along the tool rake face produces a great deal of heat and friction, which makes machining extremely difficult under these conditions. A change in direction and fluctuation in both directions of the cutting force will occur from time to time, and this is primarily determined by differences in operating conditions between the two directions of travel. The hardness, toughness, and wear resistance of a tool are just a few of the fundamental characteristics that a tool must possess in order to maintain its strength even when subjected to high cutting temperatures.

    Through the course of this article, you will learn how to reduce tool wear and increase the longevity of your tools.

    Although there is no widely accepted unified definition of tool life in the literature at the time of writing, factors such as the workpiece and tool materials, along with the cutting process used, are all factors that have an impact on the tool life. One approach is to first establish an acceptable maximum flank wear limit as a starting point, after which the quantitative analysis of the end point of tool life can be initiated, and so on.

    High-speed cutting technology requires the continuous development of optimal tool substrate, coating, and cutting edge preparation technology. This is essential for the successful application of high-speed cutting technology. If you want to reduce tool wear and resist high-temperature cutting applications, this is especially important to consider. It is possible to determine the suitability of each tool for different workpieces and machining tasks as a result of these considerations, as well as the chip breaking groove and corner arc radius that have been implemented on the indexable blade. By utilizing the most effective combination of all of these elements, the cost-effectiveness and dependability of the cutting process can be improved while simultaneously increasing productivity.

    When making your selection, make sure that the coated tools are of the highest possible quality level.

    The coating also contributes to the enhancement of the tool's cutting performance. The coating technologies listed below are just a few examples of those that are currently in use in the coating industry today.

    A variety of TIN coatings are available, as depicted in the illustration in Figure 1. TIN is a PVD and CVD coating that can be used to improve the hardness of tools as well as the oxidation temperature of the materials to which they are applied. It is a universal coating that can be applied to a variety of materials to improve their hardness and oxidation temperature.

    By incorporating carbon into the tin alloy, it is possible to increase the hardness and surface finish of the titanium carbonitride (TiCN) coating, which is used in aerospace applications.

    When cutting at high temperatures, it is possible to extend the tool life by applying an alumina (Al2O3) layer and these coatings, as well as by applying a composite application of an alumina (Al2O3) layer and these coatings. alumina coatings are particularly well-suited for cutting applications that require dry or near-dry conditions, due to their extreme hardness and durability. In contrast to TiAlN coating, which has a higher titanium content but a lower surface hardness, AlTiN coating has a higher aluminum content but a higher surface hardness. TiAlN coating has a higher titanium content but a lower surface hardness. The titanium content of the TiAlN coating is higher, but the surface hardness is lower. Although the titanium content of the TiAlN coating is higher, the surface hardness of the coating is significantly lower. In order to improve the corrosion resistance of titanium alloys, TiAlN coatings are applied to the metal. Because of their excellent wear resistance, aluminum titanium nitride (AlTiN) coatings are the most commonly used in high-speed machining applications.

    Because of its excellent antibonding properties, it has been determined that this coating is the most effective solution for antichip tumor applications currently available in the literature. The fourth step involves the application of chromium nitride (CRN) as a protective coating:

    It is possible to significantly improve the cutting performance of cutting tools when diamond coating is applied to them before they are used in non-ferrous materials. Graphite, metal matrix composites, high silicon aluminum alloys, and other highly abrasive materials are just a few of the materials that can be processed using this technology, to name a few examples. The use of diamond coating when machining steel parts is not recommended due to the chemical reaction that occurs between the coating and the steel during the machining operation, which destroys any adhesion that may have existed between the coating and the substrate during the operation.

    Thus, PVD coated tools have gained market share in recent years, and their prices are now competitive with the prices of CVD coated tools in some cases, as a result. Manufacturers state that CVD coatings have a typical thickness of between 5 and 15 microns, with thicknesses varying according to application and manufacturer. The thickness of the PVD coating varies depending on the application and environment. It can be anywhere between 2 and 6 microns thick. CVD coating will be applied to the tool substrate in this application due to its ability to increase tensile stress, which is important in this application. When a PVD coating is applied to a material after it has been deposited on it, it can result in the formation of beneficial compressive stress in the material being coated. Thick CVD coatings applied to metal surfaces, on the other hand, have been shown in the literature to significantly reduce the strength of cutting edges when applied to metal surfaces, according to the literature. CVD coating cannot be applied to cutting tools that require extremely sharp cutting edges, for example, saws, due to this limitation.
