These effects have a direct bearing on the fatigue life. In this investigation the effect of grinding conditions on the fatigue life of titanium 5Al-2.5Sn was studied. This alloy is used in ground form in the manufacturing of some critical components in the space shuttle's main engine. It is essential that materials for such applications be
2016-11-12 The grinding performance is defined significantly by grinding wheel preparation. Besides the required grinding wheel profile, the dressing process must produce appropriate wheel topography. Resultant wheel topography influences the workpiece surface roughness and surface morphology by the number and shape of the kinematical edges, the pore volume, and the wear behavior of the abrasive layer

2018-9-1 The material ground was 4340 hardened steel. The wheel was intentionally thrown out of balance by adding weights to one side of the wheel hub. The vibration due to wheel unbalance was measured at 0.00019-inch displacement. The first test involved grinding three slots at “Conditions 1,” as shown in Figure 3.
2018-6-10 The effect of grinding-induced damage, on the strength of a yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) and a zirconia-tough-ened alumina (ZTA) was investigated. The four-point flexure test was used to measure fracture strength as a function of grinding conditions.
2019-2-15 Grinding is a challenging and rewarding job, no double about it. While it takes lots of practice to master it, there are several hazards associated with it. Even the expert can’t escape it unless taken good care. Grinding hazards involves eye-injuries, affected lung, and even the danger of fire! But that only happens ONLY when Grinding
2012-12-1 Fig. 2 shows the effect of porosity on the grinding efficiency of the wheels. When the porosity is lower than 40.5%, the average time to grind a PCD blade decreases remarkably with an increase in the porosity. When the porosity reaches 40.5%, the grinding time changes little with the porosity.

The condition of grinding wheel active surface was analyzed using an advanced observation measurement system based on stylus/optical profilometry, as well as confocal and electron microscopy. The obtained results confirmed the correctness of introduction of the impregnating substance into the grinding wheel structure, and it was possible to
2020-3-23 Immediate monitoring of the conditions of the grinding wheel during the grinding process is important because it directly affects the surface accuracy of the workpiece. Because the variation in machining sound during the grinding process is very important for the field operator to judge whether the grinding wheel is worn or not, this study applies artificial intelligence technology to attempt
2013-1-22 Wheel surface condition plays an important role in the grinding operation. Grinding wheel loading, meaning chip accumulation in the space between grains, leads to deteriorating wheel cutting ability and causes excessive force and temperature. This paper presents an analytical model of wheel loading phenomena as a function of cutting parameters, wheel structure, and material properties. The
