    Notes: The combination of metal cutting theory, computer technology and expert knowledgewas used to study the use of knowledge-based engineering (KBE) for cutting large containers. Thisreport includes information on the acquirement, expression, and inference and management ofKBE. The structure of the KBE system was established by selecting the principles of processingparameters and optimizing the model of machining data and by using the method of expressingknowledge of combining producing type with frame type and by using the software SQL server2000. The inferential mechanism of every functional module in the system was realized by applyingthe software, VC++ 6.0. The KBE technology will help technicians to share expert knowledge andexperience, and to optimize cutting parameters to intellectualize cutting design and machining

    Notes: As machining technology develops toward the unmanned and automated system, theneed for chip-breaking control is considered increasingly important. In this paper, chip-breakinglimit of 3-D complicated groove insert is proposed according to cutting experiments. Themathematical formulation of chip section profile coefficient is established through the analysis ofinfluential effect of 3-D complicated groove on chip section profile. The chip-breaking model isdeveloped to predict the critical feed rate and the critical depth of cut in machining based onanalyzing the restricted effect of 3-D complicated groove on chips. Finally, a full experimentalvalidation of the analytical model is presented for chip breaking when the workpiece is steel, 45.The testing results show the critical feed rate model and critical depth of cut model are reasonableand reliable

    Notes: Based on the milling temperature experiments and researches, we established the millingtemperature mathematical model using dimension analytic method,and the heat density function andsuperficial heat density function of the flat milling insert and the waved-edge milling insert, whoserake face is wave curve plane and created by the authors using the diathermanous theory. Wedescribe the mathematic model of the instantaneous temperature field by the theory of the finitemoving planar sources of heat. At last, a program was done to calculate the heat density functionand the milling temperature field. According to the calculated results and plotted graph, it is proventhat the highest temperature is not on the knifepoint and host edge, in fact, it is offset from the hostedge a certain space. So we can make the conclusion that the waved-edge milling insert’s cuttingcapability is higher than the flat milling insert’s which is consistent with the experimental result.All the studies above are the foundation for accurately describing the 3-D temperature field andoptimizing groove

    Notes: As machining technology develops toward the unmanned and automated system, theprediction of chip breaking is considered increasingly important, especially in continuousmachining such as in cutting aluminum alloys. In this paper, chip breakers with different parametersare designed to produce chips that can be evacuated easily and reliably from the working zone. Theformulation of chip up-curl radius is constructed through analyzing the chips subject to chipbreaker. The predictive model of chip breaking is developed based on chip breaking conditions.Chip breaking strain is obtained by using backward-deducing method and cutting experiments. Inorder to verify the model, PCD tools with chip breakers are used to cut LY12, chip breaking areasare compared with those obtained from the predictive model. Results show the chip breakingpredictive model is reasonable

    Notes: Magnetic ceramic particles (NiFe2O4) and aluminum borate whiskers reinforced aluminum matrix composite was fabricated by squeeze casting technique, which had lower coefficients of thermal expansion (CTEs). The components and microstructure were characterized by X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM). The resultsshowed that the CTE of the composite was lower than that of the composite only reinforced by aluminum borate whisker, and with increasing the number of thermal cycling, the CTE of the composite became low. The results indicated that the lower CTEs of composite resulted from ferromagnetic-paramagnetic transformation of the magnetic ceramic particles

    Notes: The chip-breaking groove of a blade is one of the main factors influencing chip control. Inthis paper, we report the use of a virtual reality technique to optimize the shape of the groove on ablade according to the status of chip formation and breakage. First, by using the software, World ToolKid, the virtual cutting systems were developed to determine the linkages between the moving parts inthe machine tool and display the virtual course of chip formation and breakage. And then, the virtualreality of optimizing the shape of the turning blade groove was carried out, that is, during calculationof loci in dimensional movement and solving mathematical model of the chip breakage, by inputtingthe groove’s parameters and cutting conditions of the blade, and simulating the track in dimensionalmovement of a chip and the restricting relations between the chip and each barrier, the intersectingcoordinates in dimensional points of chips and the breaking manner could be solved. For improperchip-breaking manner, by modifying the model parameters, the blade groove was recalculated untilthe chips could be broken with ease. Based on the shapes of chips, the shape of the blades’ groove canbe optimized to get optimal shape

    Notes: Based on the milling force testing system, we have experimented with the waved-edge milling insert and the great milling insert developed by Harbin University of Science and Technology, the American Metal milling insert, the ISCAR hackle milling insert and the flat milling insert, and then compare the insert milling capability of various grooves milling inserts. We have discussed the dynamic milling force under the incontinuous cutting condition, especially the characteristic of time and frequency. Based on the power spectrum analysis of the five types of milling inserts, we have found that the insert whose groove is formed from the curve or curly planeof the period function has an advantage on minishing the milling force and resisting to vibration. The right insert geometry parameters have great effect on improving the cutting capability. By the power spectrum analysis, we found that the complex 3-D grooves milling insert is superior to the flat milling insert on minishing milling force and vibration. The analysis result proves that using power spectrum analysis in groove optimization is viable
