Abstract： The processing precision and efficiency of engraving machine are greatly affected by the feed rate Aiming at the improvement of the engraving machine's work efficiency without decreasing the accuracy， the feedback control techniques of  engraving machine's feed rate adjustment were investigated The vibration signals of axis X， axis Y and axis Z of during working process as well as the influence factors were analyzed. Based on ARM S3C2410 controller, the acceleration sensor A/D sampling technique and the Linux programming language were used， the model of feed rate and vibration signals of axis Z were established Combined with the stepping motor′s  "S" type speed control， a method based on the vibration as feedback signals to automatically adjust the feed rate was presented The results indicate that this method can improve the processing efficiency of the engraving machine， while ensuring the precision
