The Automatic Compensation of Wheel-cutting's Rotational Speed Based on Metallographic Sample Cutting Machine

During the cutting machine’s work time, the wear of the cutting piece is a constant process of gradually wear. So it is difficult to ensure the accuracy and efficiency of processing. This paper introduces the principles and compositions of a linear CCD diameter measurement system, makes a non-contact automated on-line measurement for the grinding wheel diameter; as for the wear capacity of the grinding wheel piece, it realizes the automatic compensation of rotational speed.
