Beschreibung
Zusammenfassung:	A PLC-based automatic grinding constant pressure control method, comprising: setting a required grinding rotating speed and a required grinding pressure for an object to be ground; generating a control instruction according to the required grinding rotating speed and the required grinding pressure, such that a grinding wheel mechanism operates according to the control instruction; calculating the actual pressure of the grinding wheel mechanism according to the actual output current of a grinding wheel variable-frequency drive; comparing the required grinding pressure with the actual pressure, and obtaining a pressure compensation value according to the comparison result; when the pressure compensation value exceeds a preset range, carrying out identification according to positive and negative values of the pressure compensation value and the numerical range in which the pressure compensation value falls so as to obtain compensation parameters corresponding to the pressure compensation value, the compensation
