Green Manufacturing Technology

Green manufacturing is the embodiment of the strategy for sustainable development of human society in the field of manufacturing sector. The manufacturing of parts and components can not carry out without mechanical processing. The environmental pollution caused by the traditional mechanical processing technics is very serious, especially the emissions of waste water and waste liquid during the process of machining. This paper discussed several mechanical processing technics geared to green manufacturing which are beneficial to the environmental protection, such as the dry cutting, quasi-dry cutting, low temperature air-cooling cutting, high-speed cutting as well as the near net shape forming, and finally drew the conclusion that the new mechanical processing technics combined with green technology with full consideration of the carrying capacity of resource and environment is an important part of green manufacturing in the future.

Cutting Tool Materials

Modern trends in metal cutting, high speed/feed machining, dry cutting and hard cutting set more demanding characteristics for cutting tool materials. The exposed parts of the cutting edges must be protected against the severe loading conditions and wear. The most significant coatings methods for cutting tools are PVD and CVD/MTCVD today. The choice of the right substrate or the right protective coating in the specific machining operation can have serious impact on machining productivity and economy. In many cases the deposition of the cutting tool with a hard coating increases considerably its cutting performance and tool life. The coating protects the tool against abrasion, adhesion, diffusion, formation of comb cracks and other wear phenomena.

A multi-scale and multi-phase nanocomposite ceramic cutting tool material Al2O3/TiC/TiN(LTN) with high comprehensive mechanical properties has been successfully fabricated by means of adding micro-scale TiC and nano-scale TiN particles. The cutting performance and wear mechanisms of this advanced ceramic cutting tool were researched by turning two kinds of hardened steel 40Cr and T10A respectively. Compared with the commercial ceramic tool LT55, LTN showed a superior wear resistance with certain machining parameters. The machining tests indicated that the new materials tool is suitable for continuously dry cutting of hardened steel with high hardness at high speed.

Tool Wear Mechanisms

An experimental investigation of wear mechanisms in high-speed turning of superalloy GH2132 with Al2O3-based ceramic was conducted under dry cutting condition. The tool wear mechanisms were characterized by observation of tool wear morphology using scanning electron microscopy (SEM) and detection of the element distribution of the worn tool surface utilizing energy dispersive X-ray spectroscopy (EDS). The results of turning experiments indicated that the major wear mechanisms of the ceramic cutting tool were synergistic interaction between abrasive wear and adhesive wear, and meanwhile the micro-chipping was also observed. It is also shown that cutting distance of the Al2O3-TiC ceramic cutting tool at the speed of 420 m/min was higher than that of the speed of 360 m/min and 540 m/min.

Discrete element model of fully sintering dental zirconia was constructed and calibrated. Based on the model, the dynamic process of low-speed milling of zirconia was simulated, and the effects of different cutting speeds, cutting widths and federates on the formation of surface cracks were also analyzed. Results show that residue cracks number and maximum depth increases significantly with increase of the cutting width, while the influence of cutting speed and federates is not distinct. That shows the possibility of high-speed machining on fully sintering dental zirconia with development of coating technology of cutting tool.

Dry Turning

Owing to minimum quantity or no use of toxic coolants, the dry machining technique has been evidenced to be a versatile sustainable method. However, during dry machining of ductile alloys, the severe tool wear and metal adhesion on the rake face of the cutting tool has been a matter of great concern. In the present work, an attempt has been made to assess the improvement in the tribological conditions in dry cutting by providing surface texturing on the rake face of High-Speed Steel (HSS) cutting tool. Dimples were produced on the rake surface of the HSS tool using pulsed Nd: YAG Laser and dry turning of pure aluminium is performed using the textured tool based on Taguchi’s L9 orthogonal array (OA) experimental design. The dry cutting of pure aluminium was also performed using the conventional/un-textured tool and the obtained results are used for comparison purpose. Improved turning performance in terms of material removal rate and surface roughness is found from the conformation tests using optimum process parameter determined by the Taguchi analysis. The ANOVA results suggests the effectiveness of using the textured tools during dry machining is significantly affected by feed and speed.

Using environment-friendly cutting fluid in the process of metal cutting is one of the valid paths to carry out the green manufacturing. Using metacrylic acid ester, castor oil and boride as the main raw materials, a new type of environment-friendly water-base cutting fluid had been obtained. The main components of this cutting fluid are some kind of high molecular polymer and some kind of B-containing castor oil EP agents. The test results show that the cutting fluid has good stability, antirust property and biodegradability. The maximal non-chucking load value (PB) of the cutting fluid, whose consistency is 5%, can be 1068N. In the comparison with dry cutting, cutting force using environment-friendly cutting fluid is reduced by 23% in a certain condition. Using this cutting fluid can raise stock-removing efficiency and cutting quality, and extend the service life of cutting-tool. And this cutting fluid is harmless to operators and free from pollution to the environment. Expansion and application of the environment-friendly cutting fluid are advantageous to promote the development of the green manufacturing.

Research objective: studies of economic and transport infrastructure development in the Arctic and Northern Territories of Russia. Research methodology: analysis of transport infrastructure in the Republic of Sakha (Yakutia) and the types of railways used in Russia. Results: economic development of any region is proportional to the development of the road transport infrastructure and logistics. When a conventional railway is operated in the Arctic conditions, it is not always possible to maintain a cargo turnover that would ensure its efficient use, and transshipment from one mode of transport to another is very problematic. A new type of railway is proposed, i.e. a light railway. Conclusions: the proposed new type of transport offers all the main advantages of narrow gauge railroads (high speed of construction, efficiency, etc.) and helps to eliminate their main disadvantage, i.e. the need for transloading when moving from a narrow gauge to the conventional one with the width of 1520 mm, along with a significant reduction in capital costs.
