  • Material mixing ratio in MIM-based FDM using agar binder               
    ABE Takeyuki; SAKURAI Ayano; KANEKO Jun'ichi; HORIO Kenichiro
    The Proceedings of The Manufacturing & Machine Tool Conference, Volume:2019, Number:0, First page:C14, 2019
    In FDM technology, which is performed by extruding a material from a heated nozzle using an MIM material, generally uses a resin material as a binder. This process requires degreasing and sintering steps to remove a binder after molding. The degreasing process is carried out in a dedicated apparatus using an organic solvent. In this study, using agar as a binder, it was possible to carry out degreasing and sintering processes continuously in the same furnace. In this report, the effect of material mixing ratio of metal powder, agar, and water on the density and hardness of shapes was clarified.

    In this research, I will present a high precision grinding technique of cutting edge of punch. This method performs finish grinding process planning method by simultaneous three-axis control of a conical grindstones on a machining center. Cutting edges of punch are tools used to cut out thin-walled shapes, it is necessary to limit the thickness of the tip of the cutting edge to 10 [µm] or less and to suppress a surface roughness of cutting edge, because the thickness and the surface roughness affect the generation of chips and cutting quality at the time of material cutting. I try to apply to an irregularly shaped cutting edge of punch processing condition of a straight blade that the surface roughness of the edge is suppressed by carrying out truing and the surface roughness can be further suppressed by grinding by a path tilted along the edge. As a result, it became possible to generate cutting edges of punch with complicated shapes by processing condition and tool path.

    In recent cutting processes, 5-axis controlled machine tool has become essential as the shape of the work becomes complicated, and high efficiency by short-time machining under high feed conditions is required. However, in a machining plan based on a CAM system aiming to avoid interference, there is a problem that the actual feed speed does not reach the command value and the machining time becomes longer than expected. In this report, in machines with a trunnion stage type configuration, attention is paid to the jerk value of the turning axis, and propose the tool posture planning that restrain machining speed decrease by correction command value of turning axis.

    When estimating the effect of elastic deformation of a workpiece generated during machining on machining errors in machining of low rigidity objects, it is necessary to continuously carry out finite element analysis in the shape in the middle of machining and increase in calculation time becomes a problem. Then, in this study, was attempted to drastically reduce processing time by forming a data set obtained by making processing conditions and displacement distribution information after processing to two-dimensional image information, to develop a method guessing displacement distribution by machine learning. In this paper, we explain the results obtained for the shape of the blade.

  • Accurate and fast tool path generation method for large-scale discrete shape data

    Sculptured surface on large-scale dies with complex curved surface such as automobile body parts is usually fabricated by ball-end-mill using 3-axis NC milling machines. Normally, toolpath for machining products is generated by geometric calculation between product model and tool. However, if the product has a large and complex surface, number of polyhedrons approximating the product increases, so a calculation time becomes enormous. In past research, methods of geometric calculation using offset surface generation and the parallel processing function of GPU were proposed to solve this problem. However, these methods didn't consider error due to the approximation process and increase in memory usage. To reduce this geometric error and memory usage, we propose a new method for accurate offset surface generation. In this method, the offset surface is generated by vertices of the polyhedron constituting the product and the tool radius. This approach enables accurately calculating a height of the offset surface of the area approximated by the fine polygon shape while suppressing an increase in memory usage.

  • Development of complex shape rough machining system by multi-axis control WEDM               
    TAKAHATA Masahiro; KANEKO Jun'ichi; IRIGUCHI Kenji; ABE Takeyuki; HORIO Kenichiro
    The Proceedings of The Manufacturing & Machine Tool Conference, Volume:2018, Number:0, First page:B10, 2018
    In recent years, new usage of Wire Electric Discharge Machining(WEDM) is expected for rough machining of difficult-to-cut materials such as aircraft parts. Therefore, we are developing new WEDM based on multi-axis control process. So, a new machine tool for multi-axis controlled WEDM process has been developed. The machine tool has 2-axis tilt and rotary tables and it can change the wire posture against workpiece surface. However, it is difficult to plan the path and the posture of wire avoiding the interference with the workpiece while continuously changing the posture. Thus, we propose a new planning method. This method is realized while solving the difficult problem.

  • Tool Posture Planning Method Considering with Change of Workpiece Shape with CNC Machining Process               
    KANEKO Jun'ichi; Watanabe Kento; ABE Takeyuki; HORIO Kenichiro
    The Proceedings of Mechanical Engineering Congress, Japan, Volume:2018, Number:0, First page:S1310006, 2018

    This study proposed new automatic planning method for tool posture in multi axis controlled machining process to avoid collisions between the cutting tool and workpiece shape with unremoved volume in rough machining process. The proposed method sequentially judges the likelihood of collision between holder and shank parts of the cutting tool and the workpiece surface, which is changed by machining process. Then, continuous change of tool postures without collision is automatically determined. In the proposed method, an efficient algorithm for settings of tool posture candidates is proposed. By applying the proposed algorithm, it is possible to prevent rapid changes in tool posture at each cutter location, while reducing computation time for geometric calculation. In this paper we conduct experimental estimation about tool path of scanning path. In the planned results, the proposed method can generate continuous change of tool posture within several dozen milliseconds in each cutter location.

    The needs of aluminum joints have grown in recent years. However, as aluminum forms strong oxide layers on the surface in an atmosphere, joining of these materials is di‹cult. This is where we conceived of a new inatmosphere solid phase bonding method which uses high-frequency induction heating and ultrasonic vibration. The effects of ultrasonic vibration and bonding conditions on this new bonding method were investigated. As the results, we were able to confirm the effcacy of ultrasonic waves on bonding. The bonding mechanism of new bonding method was also clear.

    The purpose of this research is to develop the technology for aluminum alloy is weld in short time and a little change shape in atmosphere. It was welded using high frequency induction heating and ultrasonic vibration for it. As a result, when applying the ultrasonic vibration to the bonding portion, the tensile strength increases with junction temperature. When applying the ultrasonic vibration to the bonding portion, it increases in the tensile strength more than the case when isn't applied to the ultrasonic vibration. This is ultrasonic vibration destroys oxide layer of aluminum alloy, and to make a joint surface generate more material flow.

    The direct metal lamination is one of the additive manufacturing processes using the arc welding technology; where the molten metal made by the arc discharge is accumulated successively in this process. In this study, two kinds of dissimilar metal fabrication were conducted. One combination is an aluminum alloy and a titanium alloy. Another is a stainless steel and a Ni based alloy. The boundaries of dissimilar metal structures were investigated. As a result, the potential of the fabrication with more than one kind of metallic material by direct metal lamination is shown.

  • Study on Residual Stress and deformation of Shell Structure Fabricated by Direct Metal Lamination Using Arc Discharge               
    Abe Takeyuki; Sasahara Hiroyuki
    Proceedings of JSPE Semestrial Meeting, Volume:2011, Number:0, First page:936, Last page:937, 2011
    In this research, an arc welding technology has been applied to melt the metal, and the fabrication system for three dimensional metallic parts, direct metal lamination using arc discharge, has been developed. In this paper, the relationship between residual stress in the shell structure and temperature distribution in the shell structure after lamination is investigated. As a result, it is clarified that residual stress is small under the condition that temperature in the shell structure is high. In addition, temperature distribution can be controlled by heat input conditions and cooling method. The residual stress distribution is formed by non-uniform compressive plastic strain distribution. The plastic deformation is caused by temperature distribution.

    Sculptured surface on large-scale dies with complex curved surface such as automobile body parts is usually fabricated by ball-end-mill using 3-axis NC milling machines. Normally, toolpath for machining products is generated by geometric calculation between product model and tool. However, if the product has a large and complex surface, number of polyhedrons approximating the product increases, so a calculation time becomes enormous. In past research, methods of geometric calculation using offset surface generation and the parallel processing function of GPU were proposed to solve this problem. However, these methods didn't consider error due to the approximation process and increase in memory usage. To reduce this geometric error and memory usage, we propose a new method for accurate offset surface generation. In this method, the offset surface is generated by vertices of the polyhedron constituting the product and the tool radius. This approach enables accurately calculating a height of the offset surface of the area approximated by the fine polygon shape while suppressing an increase in memory usage.

    When estimating the effect of elastic deformation of a workpiece generated during machining on machining errors in machining of low rigidity objects, it is necessary to continuously carry out finite element analysis in the shape in the middle of machining and increase in calculation time becomes a problem. Then, in this study, was attempted to drastically reduce processing time by forming a data set obtained by making processing conditions and displacement distribution information after processing to two-dimensional image information, to develop a method guessing displacement distribution by machine learning. In this paper, we explain the results obtained for the shape of the blade.

    In recent cutting processes, 5-axis controlled machine tool has become essential as the shape of the work becomes complicated, and high efficiency by short-time machining under high feed conditions is required. However, in a machining plan based on a CAM system aiming to avoid interference, there is a problem that the actual feed speed does not reach the command value and the machining time becomes longer than expected. In this report, in machines with a trunnion stage type configuration, attention is paid to the jerk value of the turning axis, and propose the tool posture planning that restrain machining speed decrease by correction command value of turning axis.

    In this research, I will present a high precision grinding technique of cutting edge of punch. This method performs finish grinding process planning method by simultaneous three-axis control of a conical grindstones on a machining center. Cutting edges of punch are tools used to cut out thin-walled shapes, it is necessary to limit the thickness of the tip of the cutting edge to 10 [µm] or less and to suppress a surface roughness of cutting edge, because the thickness and the surface roughness affect the generation of chips and cutting quality at the time of material cutting. I try to apply to an irregularly shaped cutting edge of punch processing condition of a straight blade that the surface roughness of the edge is suppressed by carrying out truing and the surface roughness can be further suppressed by grinding by a path tilted along the edge. As a result, it became possible to generate cutting edges of punch with complicated shapes by processing condition and tool path.

    In FDM technology, which is performed by extruding a material from a heated nozzle using an MIM material, generally uses a resin material as a binder. This process requires degreasing and sintering steps to remove a binder after molding. The degreasing process is carried out in a dedicated apparatus using an organic solvent. In this study, using agar as a binder, it was possible to carry out degreasing and sintering processes continuously in the same furnace. In this report, the effect of material mixing ratio of metal powder, agar, and water on the density and hardness of shapes was clarified.

    This study proposed new automatic planning method for tool posture in multi axis controlled machining process to avoid collisions between the cutting tool and workpiece shape with unremoved volume in rough machining process. The proposed method sequentially judges the likelihood of collision between holder and shank parts of the cutting tool and the workpiece surface, which is changed by machining process. Then, continuous change of tool postures without collision is automatically determined. In the proposed method, an efficient algorithm for settings of tool posture candidates is proposed. By applying the proposed algorithm, it is possible to prevent rapid changes in tool posture at each cutter location, while reducing computation time for geometric calculation. In this paper we conduct experimental estimation about tool path of scanning path. In the planned results, the proposed method can generate continuous change of tool posture within several dozen milliseconds in each cutter location.

    In recent years, new usage of Wire Electric Discharge Machining(WEDM) is expected for rough machining of difficult-to-cut materials such as aircraft parts. Therefore, we are developing new WEDM based on multi-axis control process. So, a new machine tool for multi-axis controlled WEDM process has been developed. The machine tool has 2-axis tilt and rotary tables and it can change the wire posture against workpiece surface. However, it is difficult to plan the path and the posture of wire avoiding the interference with the workpiece while continuously changing the posture. Thus, we propose a new planning method. This method is realized while solving the difficult problem.

    In this research, an arc welding technology has been applied to melt the metal, and the fabrication system for three dimensional metallic parts, direct metal lamination using arc discharge, has been developed. In this paper, the relationship between residual stress in the shell structure and temperature distribution in the shell structure after lamination is investigated. As a result, it is clarified that residual stress is small under the condition that temperature in the shell structure is high. In addition, temperature distribution can be controlled by heat input conditions and cooling method. The residual stress distribution is formed by non-uniform compressive plastic strain distribution. The plastic deformation is caused by temperature distribution.

    In additive manufacturing utilizing wire material and arc discharge, a magnesium alloy, which is a lightweight and high specific-strength metal, can be applied for fabrication with high precision by active cooling with solid block contact to the supplied molten metal. Furthermore, on the surface layer, the possibility of deposition of dissimilar metals such as Ti alloy and Al alloy, which have superior heat resistance, corrosion resistance and wear resistance compared to Mg alloy, was investigated. The metallographic state and bond strength at the interface were also clarified. Although the metallurgical bonding strength of these combinations is low due to the formation of intermetallic compounds at the interfaces between dissimilar metals, the additive process itself is feasible.

    We proposed a new processing method that simultaneously performs metal additive manufacturing, which melts and deposits wire materials by arc discharge, and finishing processing using a rotary tool. The proposed method improves the shape accuracy of the accumulates, and at the same time suppresses the anisotropy of the microstructure of the accumulates by the stirring action and plastic strain given by the rotary tool. The microstructure of the accumulates after finishing with a cutting tool and FSB tool was evaluated, and the feasibility of the proposed method were shown. It was also clarified that the relationship between the solidification state of the accumulates and the anisotropy.

    A quality of casting product is influenced by the pouring process in the casting industry. Therefore, it is required to develop the automatic pouring machine replicating the skilled pouring work. In this study, we developed the assessment system of pouring skill and the pouring control system which replicates the pouring flow rate obtained from the assessment system as the teaching data. As the results in this study, the manual pouring works were scored by the developed assessment system. And, we realized the pouring control system which refers the pouring flow rate obtained from the assessment system.
