Opis:: Recently, high efficient solar power generation is required because eco-awareness is increasing. High efficient generation becomes possible by focusing sunlight on electric generating element, i.e. CPV (Concentrator photovoltaic). Although the concentrator is used for focusing sunlight, it demands large spherical surface with high solar reflectance, fine accuracy and lightweight. Aluminum is considered as suitable material for concentrator. However, mirror-like processing on large spherical surface is very difficult. Therefore, new polishing technology for aluminum was developed and evaluated in this paper.Main objective is to obtain high solar reflectance by improving surface roughness. As a trial study, workpiece was not large spherical but small and flat. Firstly, the polishing tool which attached polishing cloth was developed.Optimum polishing cloth for tool was investigated by trial and error approach. When workpiece was heated before starting polishing, a number of oxides were adhered to polishing cloth and surface roughness was improved efficiently.Then optimum polishing condition was decided by using design of experiments method. Finally, solar reflectance on polished surface was measured and evaluated. It is concluded from these results that (1) the developed polishing technology was effective for processing the mirror-like surface on the surface of aluminum, (2) 82% solar reflectance was obtained with developed polishing technology by improving surface roughness of workpiece.

Opis:: Recently Taguchi methods are used to decide optimum processing conditions with narrow dispersion for robust design. On the other hand, innovative development with short-term, low cost, labor and energy saving is also required in the world. In this study, the software for development of a product with optimum condition using Taguchi methods is developed and evaluated. There are two trials in the software using Taguchi methods. First trial investigates rough functions regarding all levers of all control factors, then important control factors and meaningless control factors were sorted with the several comments for the second trial. At that time, maximum, intermediate and minimum values for each lever of each of the control factors should be used for pursuit of all possibilities. In the first trial, the relationship between each level value of each of the control factor and the desired property is also decided by the function, then the optimum combination using each level of each of the control factors were calculated for the second trial by using the function. The second trial is confirmed for the best combination using the estimated optimum level values. For example of an application, the optimum design for the paper craft “airplane” was investigated for evaluating this software in the experiment. It is concluded from the result that: (1) The proposed software was useful for developing with short-term and lower cost, (2) This tool could quickly and exactly decide the optimum design condition and (3) The paper craft “airplane“ with most long flying length is manufactured by using the developed software.

Opis:: Recently titanium alloys and nickel alloys have become eminent for making aeronautic and astronautic parts. Since both nickel alloys and titanium alloys have a very small thermal conductivity, the being used tool will suffer from a huge damage by heat generated during cutting process. Therefore, there is a requirement for a durable tool with excellent cooling capacity. In this research, a new electro-deposited diamond tool for high speed cutting of nickel alloys and titanium alloys was developed and evaluated. The new tool is a cup shaped end mill, its body is made from copper (due to its superior heat conduction characteristics) and the platting layer for bonding the diamond grains #120 is nickel. The cooling system is an advancement of the former used heat pipe. Water is supplied from outside through a thin tube, that is integrated in the tool body. Thereby the effect of water evaporation, featuring a very large cooling capacity, could be applied. The assayed materials were Ti6Al4V and Inconel 718. The cutting conditions were investigated by some pre-experiments. It is concluded from the results that; (1) The cooling capacity of the new tool using water evaporation is very effective to maintain the grinding potential of electro-deposited diamond tools, (2) The new tool is effective for high speed grinding of nickel alloys and titanium alloys (3) The new tool and compulsory cooling system are economical and eco-friendly.

Opis:: Recently, many micro structure products are used for compact, high precision and others functions in the field of measuring instruments, medical instruments, information processing devices and so on. However, in the small sliding parts of these products, the surface contact pressure becomes lowered and then, higher adhesive force occurs, resulting larger coefficient of friction. On the other hand, in the field of machine tools, lubrication free sliding parts are also demanded for eco-friendly. In this study, the surface treatment for improvement of coefficient of friction for both light load and heavy load applications are investigated. When laser ray is applied on stainless steel surface, CrO2 layer with small concaves like dimple is generated. This CrO2 layer is used in light load applications. Next, TiAlN and DLC coating are being used on cutting tools for reducing coefficient of friction and cutting heat. Therefore, these coating materials are used for heavy load and oil free applications. The improvement of coefficient of friction and life of coating are investigated by experiments. It was concluded from the results that; (1) Coefficient of friction for light load application can be reduced by coating CrO2 layer. (2) Coefficients of friction for heavy load application were reduced by coating TiAlN and DLC layer. (3) Life of both CrO2 and DLC layers are sufficiently long for practical applications at light load and heavy load respectively.

Opis:: Nowadays, eco-friendly manufacture has become common request in the manufacturing and production. The excessive electric power associated with the usage of large amount of oil for cooling and lubrication during machining can increase the CO2 emission which is considered as large problem for environment. On the other hand, the presence of the unwanted vibration during machine can affect the quality of production. The influence of immersed machine tool in strong alkaline water has been investigated in previous work for normal machine operation when no vibration occurred. In present research, the influence of immersed condition to the vibration of the bench lathe machine was investigated. Thermal deformations of the spindle when operating bench lathe coincide with machine resonances were also measured for evaluation of accuracy. The calculation of CO2 emission using immersed bench lathe machine was done by comparing with the conventional machining. It is concluded from the results that; (1) Excellent cooling efficiency can be achieved by using strong alkaline water added with microbubble, (2) Vibration of machine tool was reduced during immersed condition, (3) Thermal deformation of the bench lathe was very small despite no-forced cooling was used, (4) The large number of CO2 that released annually can be reduced by immersed of machine tool.

Opis:: In the 21st century, as it is important to produce the products with high accuracy, high quality and eco-friendly, the most of manufacturers need several daring plans, unique ideas and new technologies. For example, in machine tool technology, restraint of vibration on the machine tool was required for high accuracy and quality, and several countermeasures using costly equipment and large quantity of electrical energy were used for the restraint, however those countermeasures are not enough. Therefore a countermeasure of vibration for machine tool using alkaline water with polymer was developed and evaluated. Polyethylene oxide was used for the polymer because of the low cost and the safety for health. Relationship between the mixed polymer in the alkaline water and the damping ratio were firstly investigated. And the optimum percentage of the polymer was decided for restraint of vibration on a machine tool. Then the damper structures using alkaline water with polymer were development, and the three dampers were set for restraint of vibration in the small machine tool; those are the support units, the vise and the head stock. Each damper was evaluated regarding noise and vibration on the machine tool and surface roughness on a work piece in the experiment. It is concluded from the results that; (1) the optimum percentage of the polymer for the damper was 6 wt%, (2) the damper structures using alkaline water with polymer were very effective for restraint of both noise and vibration on the machine tool and smoothly surface on the work piece.

Opis:: Establishment and selection of proper cutting condition can improve tool life and final cutting result. Cutting speed, feed speed, depth of cut and selection of tools are conditions of cutting that determined the cutting accuracy. However, when the optimum cutting condition with selected cutting speed coincides with machine resonance frequency, large vibration will occur. Consequently, even small periodic of driving forces can produce large amplitude vibrations. The simple technique to lower resonant frequency of machine tool was developed in previous research by using mixture of water and polymer with 6wt% concentration. As it was difficult to obtain damping ratio when the concentration is larger than 6wt%, therefore, the aim of this paper is to change machine resonant frequency for optimizing cutting condition by improving mixture concentration of water and polymer. It is concluded from the results that (1) By controlling machine tool resonance frequency enable cutting speed to be used for processing at its optimum cutting condition (2) New damping value of polymer mixed with water was presented, (3) Machine vibration reduced as resonance of machine was successfully avoided and surface roughness was also improved.

Opis:: Lapping is an old traditional machining process that has been useful all along in the human history. Uniform surface finishing by manual hand lapping on cylindrical inner and end surfaces are very difficult. Additionally, the geometrical form accuracy and productivity are lower. In a previous study, the new lapping method for outer cylindrical surface using the lathe with linear motor has been reported. However, this method could not be applied directly for the cylindrical inner and end surfaces. Therefore, lapping for mirror-like finish on cylindrical inner and end surfaces using the lathe with linear motor is investigated. In this study, lapping tool was modified from previous study to be suited for the cylindrical inner and end surfaces. Then, lapping methods for inner and end surfaces were developed for uniform mirror-like finish. Surface roughness and geometrical form accuracy improvement were measured for both surfaces. The optimum conditions for high productivity and high quality mirror-like surfaces were investigated. It was concluded from the results that, the developed lapping system was able to process mirror-like surface on cylindrical inner and end surfaces. Moreover, the optimum conditions for the mirror-like surfaces were revealed experimentally.

Opis:: In recent years, the urgency to create environmentally-friendly technologies has dramatically increased. However, these technologies are usually not adopted due to their large cost and low profit. Previously the “Double-ECO model” has been proposed as a methodology that reconciles both “Economy” and “Ecology”, which relies on the exploration of technology alternatives that offer an improved mechanical performance. Here, as mechanical performance, cost and environmental impact were meant to be approached under the same degree of priority, this model was thought to offer the basis for a broader technology development framework. The current research initiates said framework by proposing an evaluation platform, which through a transition from a focus on environmental-friendliness towards an improved eco-efficiency definition lays groundwork for an automated evaluation. This was done by defining a dimensionless evaluation parameter based on existing methodologies and referred as the “DE Index”. This paper applied the proposed evaluation method into a machine tool lubrication technology example. It was concluded that, (1) the platform was able to effectively compare technologies under the proposed eco-efficiency parameter, (2) the developed technology possessed improvements in the environmental pollution output, mechanical performance and cost when compared to conventional technologies.

Opis:: Recently, the use of hard materials has increased for product quality and safety reasons. Consequently, the cutting conditions for these materials become severe resulting in shorter tool life due to higher cutting temperature. In this paper, tool technology to reduce heat generation and its influences during cutting is investigated and evaluated experimentally. The approach for reducing cutting heat generation is considered by changing the tool geometry and reducing the frictiona coefficient between tool and chip. The approach for reducing influence of the generated heat is application of a therma insulator (coating) on the tool material having high thermal conductivity and heat-resistance. The turning process is used in the experiments. The thermal influences are made clear by each experimental parameter and then, the optimum tool parameters were considered from experimental results. It is concluded that; (1) When rake angle was 15 degree, temperature rise on the tool was smallest. (2) Temperature rise on the tools coated with TiAlN or DLC (Diamond Like Carbon) were reduced from 20 % to 30 %. (3) Several tool materials were quantitatively evaluated by consideration of the thermal conductivity, as well as thermal dependency of their hardness.
