Grinding performance of AISI D6 steel using CBN wheel vitrified and resinoid bonded

Grinding Wheel Loading Evaluation by Using Acoustic Emission Signals and Digital Image Processing

“…As shown, some metal loading debris and abrasive grains are misjudged, so a step of overlap processing is used to overcome this problem. For this step, three images in steps (1), (2), and (3) are overlapped into another image, as shown in Figure 7e. Having done so, a simple morphological operation followed by a particle filtering procedure is performed to remove any noise and segment the metal loading debris from the overlapped image, as shown in Figure 7f.…”

“…In machining operations, for cutting hardworking materials and precise gears, grinding process is a standard and dominative process due to its intrinsic and efficient machining mechanism [1]. Grinding process is also used as the final machining step to produce a precise workpiece with good surface finish and accurate sizes [2]. It means that the failure of the grinding process may lead to irreparable result for the ground workpiece and increase extra manufacturing cost [3].…”
