Crack extension is critical in determining surface forming process and machined surface quality of hard brittle materials. However, there is still a lack of research on this subject. In this work, the effect of crack extension on surface formation mechanism and surface morphology of silicon nitride ceramics was investigated via longitudinaltorsional composite ultrasonic-assisted mill-grinding, and reconstruction model of machined surface morphology considering crack extension was proposed. This model was quantitatively characterized and evaluated by the average roughness Sa and the kurtosis Sku. It is found that simulation results considering crack expansion were in good agreement with experimental results. Average relative errors in average roughness and kurtosis were found to be 7.95% and 9.46%, respectively. Primary effect analysis was performed to understand the influence of process parameters on machined surface morphology. It is found that ultrasonic vibration leads to changes in shear angle and shear velocity of abrasive grains, thereby changing machined surface morphology. Results presented here provide practical method for predicting and controlling machined surface quality during precision machining of ceramic materials.

“…They also divide the grinding modeling practice into macro and micro models according to the scale of modeling. The above research on conventional grinding is mainly concentrated in the last century, in recent years the rise of composite processing technology ultrasonic assisted grinding has been widely used, there are a large number of scientific research to prove that ultrasonic assisted grinding hard and brittle materials (such as ceramics [11][12][13][14][15][16]) and ductility materials (such as steel [17], nickel-based superalloys [18], titanium alloys [19]) in reducing grinding force, improving surface quality and so on Surface is better than CG. Consequently, it is necessary to develop ultrasonic composite processing technology for ceramics.…”

A longitudinal ultrasound-assisted grinding (LUVAG) alumina ceramics grinding force model and an LUVAG end grinding force model were developed in order to examine the influence of different parameters on the grinding force. Experiments were conducted to determine the effective cutting trajectory of grinding transient single abrasive grains and the effective removal volume of transient material. The experimental results showed that the tangential grinding force was positively correlated with table speed, grinding depth and wheel speed, the tangential grinding force was negatively correlated with ultrasonic amplitude, the forward grinding force was positively correlated with grinding depth and table speed, and the forward grinding force was negatively correlated with ultrasonic amplitude and wheel speed. The calculated results of the theoretical model of grinding force and the differential images showed that the experimental results and the calculated results could accurately reveal the influence of various factors on the trend of grinding force. By performing the extreme difference analysis on the grinding force data obtained from the LUVAG test, it was found that the grinding force was minimized when the ultrasonic amplitude was 12μm, the grinding wheel speed was 3500 r/min, the grinding depth was 5μm and the feed rate was 400 mm/min. Meanwhile, it is proved that the model can assist orthogonal experiments for factor screening and scheme optimization, which has important practical application value.

Many problems of GCr15SiMn high-carbon chromium bearing steel have been found in the ordinary grinding (OG) process. Aiming at the problems of high grinding force, low residual compressive stress and low surface quality, ultrasonic machining technology is combined with OG. The test of ultrasonic vibration assisted grinding (UVAG) GCr15SiMn high carbon chromium bearing steel is carried out. The residual stress, surface roughness, grinding force, and surface morphology are analyzed by changing machining parameters. The research showed that as the grinding depth and feed speed become larger, the grinding force increased, when the spindle speed rises, the grinding force becomes smaller. In the test range, with the ultrasonic amplitude from small to large, the grinding force from large to small. The ultrasonic grinding force is 27.8% lower than that of OG. The surface roughness increases with increasing grinding depth and feed speed and decreases with increasing spindle speed and ultrasonic amplitude, and at an amplitude of 6 μm, the surface roughness is reduced by 27% compared to OG. When the feed speed and grinding depth are lowered or the ultrasonic amplitude is increased, the surface residual compressive stress is increased. Compared to OG, it is increased by more than 13.5% under the same parameters. At the same time, the phenomenon of burrs and surface tears can be reduced, and the surface quality of the workpiece becomes better.
