    Notes: Laser processing of super-abrasive grinding wheel is paying a role in a truing/dressingtechnique to complement mechanical methods recently. However, normal dressing/truing is difficultowing to the toughness of metal-bond materials and high hardness of diamond abrasive. Bothgeometric and mathematic models were developed to improve laser processing quality and predictvarious processing parameters, such as focal offset, and incident power, and power density toperform material removal during laser processing a metal-bond diamond grinding wheel. Varioustrends of the geometrical features of dressing zone in terms of the varying focal offsets wereanalyzed. Discussions were also given on dressing-zone geometry control. Experimental studieswere carried out using different processing parameters to test the effects of laser poweres ondressing quality. Further grinding-force measurement determined the laser dressing parameters withrespect to the wheel surface conditions. The normal force FN reduces up to 20%, while tangentialforce FT decreases to 7% too.The outcomes were shown well agreement with predicted results

    Notes: Electrochemical abrasive belt grinding (ECABG) technology, which has the advantageover conventional stone super-finishing, has been applied in bearing raceway super-finishing.However, the finishing effect of ECABG is dominated by many factors, which relationship is socomplicated that appears non-linear behavior. Therefore, it is difficult to predict the finishing resultsand select the processing parameters in ECABG. In this paper, Back-Propagation (BP) neuralnetwork is proposed to solve this problem. The non-linear relationship of machining parameters wasestablished based on the experimental data by applying one-hidden layer BP neural networks. Thecomparison between the calculated results of the BP neural network and experimental results underthe corresponding conditions was carried out, and the results indicates that it is feasible to apply BPneural network in determining the processing parameters and forecasting the surface quality effectsin ECABG

    Notes: We have developed the laser nanoprocessing technique by the integration of the fs laserand near-field scanning microscopy (NSOM). The second harmonic femtosecond laser working inthe optical near-field with the assistance of NSOM equipment was applied to expose thephotosensitive polymer material. The nanopatterns with feature size smaller than the laserwavelength can be fabricated. The optical diffraction limitation is therefore broken through by thenear-field nanoprocessing. It was found in our experiment that the nanofabrication feature sizedepends strongly on the gap between the fiber probe tip and the substrate surface, as well as thelaser coupling efficiency. The approach offers the advantages of high precision, speed andselectivity in nanopatterning, and is promising to be used in data storage device manufacture forhigher density recording

    Laser Truing and Dressing of Small Vitrified CBN Grinding Wheel (2007)

    Notes: This paper aims at the development of an alterative technique for truing and dressing asmall vitrified CBN grinding wheel used for the internal finishing of small holes measuring severalmillimeters in diameter. In conventional truing and dressing, a single-tip diamond dresser or a rotaryGC cup wheel dresser is employed. This levels off the improvement in the wheel truing accuracybecause the stiffness of the grinding wheel shaft with an open-sided structure is low, and the shaft isthus deformed easily due to the truing force. In the present work, a new truing and dressing techniqueis proposed in which a Nd:YAG laser beam is employed as the dresser. Experiments were carried outwith respect to the effects of the laser beam conditions (amplitude, width and frequency of pulse, andfocus offset) and the relative motion between the laser beam and CBN wheel. It was found that therun-out of the CBN wheel was decreased significantly, and the wheel surface condition was improvedgreatly after laser truing and dressing

    Notes: By analysing the change of the anodic surface topography in Electrochemical AbrasiveLapping (ECAL), the influence of the lapping action and the electrochemical action on the anodicsmoothening velocity is studied. In electrochemical finishing, the micro-peaks on the anodic surfacecould be smoothened quickly by electrochemical action and the surface topography presents theprofile wave, but in ECAL, the profile wave after electrochemical action could be divided intomicro-peaks renewedly by lapping action and the alternation of electrochemical action and lappingaction makes the surface topography before electrochemical action present profile micro-peaks,which will increase the anodic smoothening velocity. The influence of machining parameters, such asabrasive grain sizes, tool’s pressure, abrasive content, frictional velocity and current density etc, onthe anodic smoothening velocity is discussed in detailed

    Notes: Hydroxyapatite(HA) nanoparticles with hydrophobic surface have been synthesizedusing mono-alkyl phosphate (MAP) as modifier by hydrothermal synthesis method. Thedrug-loaded nano-HA/ Poly(ε-caprolactone)（PCL）composite microspheres and drug-load PCLmicrospheres were fabricated by an S/O/W emulsion solvent evaporation method. The microspheresmorphology was investigated by scanning electron microscopy (SEM). Drug distribution inmicrosphere matrix was studied by confocal laser scanning microscope (CLSM). The resultsshowed that the drug distributed evenly in the drug-HA-PCL microspheres, but only around thesurface of the drug-PCL microspheres. The drug release profile showed that the nano-HA/PCLhybrid microspheres had low initial burst and could release continually for 90 days. This kind ofhybrid microspheres can be used as a promising long-term drug delivery system in the bone

    Notes: A precipitation-pyrolysis process was developed for the synthesis of MgO nano-particles with diameter of 20~100 nm by using organic reagent, glycol, n-butanol and N,N-Dimethylacetamide, as shape and size controller. XRD and TEM were used to study on composition, morphology and size of the as prepared MgO nanoparticles. The results indicate that organic crystal controller is one of the key factors affecting the sizes and shapes of the nano MgO particles. When using glycol as a crystal controller, the dispersion of nano MgO particles is better and olive-shaped particles with sizes of 20~40 nm are prepared. When nano MgO particles are synthesized by MgCl2 and Mg(NO3)2, their particle sizes are smaller and their particles with olive shape. During chemical reaction process, Mg(OH)2 particles are already formed to be nano scale. Calcination process at the temperature of 650ºC can change the crystal shape slightly. FTIR results show that nano MgO particles have abnormal infrared absorption behaviors compared with that of micron scale

    Notes: The behaviors of trace element Er on binary Al-Mg and ternary Al-Mg-Mn alloys havebeen investigated through optical microscopy, x-ray diffraction, scanning electron microscopy withenergy dispersive spectroscopy and transmission electron microscope. It was found that Er additionsmore than 0.4% (wt%) produced a remarkable refinement in grain size of Al-Mg and Al-Mg-Mnalloys castings. Er can enhance the tensile strength of the two group experimental alloys significantlybut not greatly decrease the elongation due to the formation of many fine like spherical and dispersiveprimary and precipitation Al3Er particles during casting and heating process. Al3Er particles have L12crystal structure (space group Pm3m) with a lattice parameter of 0.42119nm, and have a coherentrelationship with the matrix phase α-Al (mismatch only 4.1%), which can be acted as theheterogeneous nucleus during solidification to increase the rate of nucleation, and the other hands itcan strongly pin up dislocations and subgrain boundaries and retard the recrystallization of alloys
