    Notes: The present study was undertaken to compare the consumed power in surface grinding ofthree different materials with a vitrified CBN wheel. High speed steel, stainless steel, and naturalgranite were used as the workpiece materials in the experiments. Two different depth of cut andworkpiece velocity were combined to give different material removal rates. The spindle power wasin-process monitored in each pass of grinding. The radius wear of the grinding wheel was alsomeasured and the morphologies of CBN grains were observed during the grinding of high speed steeland granite. The power for the grinding of high speed steel was found to be the lowest under anyoperating parameters. For other two materials, the results became complex. At shallower depth of cut,the power for the grinding of stainless steel was higher in most cases. However, the power for thegrinding of granite was higher under larger depth of cut. It was found that the grinding wheel failedmuch earlier in the grinding of granite as compared with the grinding of high speed steel

    The Effects of Coatings at Diamonds on the Mechanical Behavior of Metal-DiamondComposites (2007)

    Notes: The present study was undertaken to examine the effects of metal coatings at the surfacesof diamonds impregnated in metal bond matrices. Diamonds with or without coatings wereincorporated into same bond matrix to form two metal-diamond composites in order to reveal theeffects of coatings. Diamonds with same coatings were applied to three bond matrices to check theinfluences of matrix properties on the effects of coatings. The transverse rupture strength (TRS) ofthe composites was measured to ssess their mechanical behavior. Circular sawing was also conductedto reveal the contribution of coatings to diamond retention. SEM was used to analyze the fracturedsurfaces of the composites. For same bond matrix, the coatings at diamonds were found to increasethe TRS of the composites. However, it is difficult to compare the effects of coatings in different bondsystems

    An Experimental Study of Specific Energy in Grinding Granite (2004)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 471-472 (Dec. 2004), p. 625-629

    Notes: An investigation is reported of the characteristics of specific energy in grinding of granite using diamond abrasives. The effects of many parameters, such as the types of diamond tools, the types of abrasives, the properties of granite, the conditions of lubrication, and the working conditions of diamond tools, were studied. The power consumed in grinding was measured in order to obtain the specific energy, which is defined as the energy expended per unit volume of material removal. It is found that the specific energy for grinding of granite was closely related to the removal mechanisms of granite, the failure modes of diamonds and the interactions of the swarf with the applied fluid and bond matrix

    Fabrication of Ultra-Fine Diamond Abrasive Tools by Sol-Gel (2004)

    Notes: In this paper, an experimental study was carried out to fabricate a new kind of ultra-fine diamond abrasive tools by means of sol-gel. The physical properties of the new diamond abrasive tools were evaluated in terms of the bulk density and hardness. The ultra-fine diamond tools were then used to polish granite on a vertical spindle grinding machine. SEM and optical microscope were applied to observe the surface morphologies of the diamond tools and granite. No obvious gathering of ultra-fine diamond grains were found in the new diamond abrasive tools, which exhibited a good wear-resistant ability in polishing. The granite surfaces polished by the new diamond tools were found to be basically smooth except few cracks originally existing in the granite

    Neural Network Prediction of Segment Wear in Stone Sawing (2004)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 471-472 (Dec. 2004), p. 485-489 
    Details
    ISSN: 1662-9752

    Notes: An investigation was carried out to predict the wear performance of diamond sawblade segments by using a Levenberg-Marquardt backpropagation (BP) neural network. The wear of the diamond segments were measured in circular sawing of natural gray granite in order to train the network and examine its validation. Since the depth of cut and workpiece speed are two main variables in the sawing of a specific granite material with a fixed diamond sawblade, a 2-5-1 structure of BP network was found to be capable of predicting the wear performance. In spite of the limited experimental data, the average value of relative errors between the simulated and measured results was found to be around 10%. Since experimentally measuring of segment wear is a time-consuming job, the trained network was also used to predict the wear performance under a very wide range of operating parameters, which can provide a useful guideline for the optimization of stone sawing

    Notes: In this study, rock minerals of natural stone were finely polished with loose abrasive andELID technology to study the surface behaviours. After these rock specimens were polished to ultrasmooth surfaces, the surface characteristics were observed with microscope and analyzed withsurface texture analyzer. It was found that the calcite and fluorite minerals could be polished to highsurface quality with fine loose aluminum oxide abrasive. But ultra smooth quartz surface must befinished with superabrasive ELID polishing technology. The weakly acidic coolant might bringchemical damage to calcite and fluorite minerals under the condition of ELID polishing process

    Effects of the Wear Characteristics of Brazed Diamond Grits on Grinding Forces (2007)

    Notes: Grinding forces, protrusion and wear of diamond grit have been studied in grinding granitewith a single-layer brazed diamond wheel. The experiment results indicate that the primary wearprogression of diamond grits in the whole grinding process follows the mode of whole,micro-fractured, macro-fractured and pull-out when grinding granite with the brazed diamond wheel.The proportions of the whole, fractured, pull-out, break flat and the mean height protrusion of grainsare more closely related to grinding forces. The grinding forces decreased with the increasingproportions of whole and break flat grains, and the tangential and normal force components increasedwith the gradual wear of the brazed diamond wheel during a long-time grinding process
