“…As described above, the primary efforts have been mainly focused on discovering appropriate approaches to generate sufficiently high cooling efficiency through the direct contact of cryogenic liquid nitrogen [11][12][13][14][15][16][17][18] and produce cooling that results in uniform mechanical properties of the products [19,20].

As nitrogen is nonreactive and non-flammable, it can provide a quick and simple medium of cooling and environment protection. One disadvantage of nitrogen cooling is its lower heat transfer coefficient than water. Despite its lower cooling capacity, nitrogen cooling can produce cleaner products, thereby eliminating the need to wash the parts and dispose of the contaminated water. In this study, an innovative nitrogen cooling system was developed for an accelerated and eco-friendly cooling of metallic parts. The dry nitrogen gas, transported via the nozzle of a cryogenic liquid nitrogen tank, is passed into the cooling chamber and exchanges heat with the workpiece. The heated nitrogen gas is forcibly transported to the chiller, where the heat is reduced, and the cooled gas is circulated again. The performance of this nitrogen cooling system has been evaluated with cooling experiments of sintered tungsten heavy alloys. The nitrogen-cooled product shows a clean surface with improved mechanical properties. Furthermore, nitrogen induces less distortion compared to water cooling, thus reducing the post-machining costs.

“…M. Dhananchezian [64] described the machinability characteristics of turning Hastelloy C-276 with a Physical Vapour Deposition (PVD) coated nano-multilayer TiAlN carbide cutting tool using dry turning and liquid nitrogen cooling methods. The improvement of cutting tool performance was achieved under liquid nitrogen cooling by the control of the wear mechanisms, which in turn reduced the wear rate.…”

The Critical Raw Materials in Cutting Tools for Machining Applications: A Review

et al. 2020

A variety of cutting tool materials are used for the contact mode mechanical machining of components under extreme conditions of stress, temperature and/or corrosion, including operations such as drilling, milling turning and so on. These demanding conditions impose a seriously high strain rate (an order of magnitude higher than forming), and this limits the useful life of cutting tools, especially single-point cutting tools. Tungsten carbide is the most popularly used cutting tool material, and unfortunately its main ingredients of W and Co are at high risk in terms of material supply and are listed among critical raw materials (CRMs) for EU, for which sustainable use should be addressed. This paper highlights the evolution and the trend of use of CRMs) in cutting tools for mechanical machining through a timely review. The focus of this review and its motivation was driven by the four following themes: (i) the discussion of newly emerging hybrid machining processes offering performance enhancements and longevity in terms of tool life (laser and cryogenic incorporation); (ii) the development and synthesis of new CRM substitutes to minimise the use of tungsten; (iii) the improvement of the recycling of worn tools; and (iv) the accelerated use of modelling and simulation to design long-lasting tools in the Industry-4.0 framework, circular economy and cyber secure manufacturing. It may be noted that the scope of this paper is not to represent a completely exhaustive document concerning cutting tools for mechanical processing, but to raise awareness and pave the way for innovative thinking on the use of critical materials in mechanical processing tools with the aim of developing smart, timely control strategies and mitigation measures to suppress the use of CRMs.

“…Cryogenic cooling with liquid nitrogen provided less tool wear and surface roughness and researchers concluded the cryogenic cooling as a clean technique because liquid nitrogen easily evaporates after penetration that agreed with previous described review results. Dhananchezian [109] studied the mechanical characteristics of difficult to cut metal Ni based Hastelloy C-276 under cryogenic cooling and dry turning. This cooling technique reduced cutting zone temperature 61~68%, cutting force and surface roughness by 8-33% than dry turning.…”

Various types cooling/lubrication techniques are used in machining processes for enhancing machining performances. Conventional way of cooling/lubrication requires higher coolant cost, waste and disposal cost. Not only has that it had many negative impacts on environment and operators health. For attaining highest efficiency of cutting fluids with minimum quantity, different sustainable strategies are tried to develop. In recent decades researchers are worked out on different cooling/lubrication strategies alternative to conventional cooling. This paper represents a comprehensive review of all presently practiced cooling/lubrication strategies and their effects on different aspects such as surface quality of machined component, tool wear, tool life, cutting temperature, cutting forces etc. through analyzing selected papers. The influence of different cutting fluids such as solid lubricants, nanofluids, ionic liquids etc. with their positive and negative impacts is also discussed. The research gaps are also identified for further research works. From review it is clear that the machining performance is highly affected by cooling techniques and coolant types. Selection of proper cooling technique with suitable cutting fluids depends on work material, tool material and cutting variables.
