The Adaptive Numerical Control System Based on Cutting Force Restriction

摘要

Precision measurement for cutting force plays an important role in the machining accuracy and efficiency of the numerically controlled machine tools. But the traditional measurement has many deficiencies. A new indirect method of measuring cutting force was proposed in which the current signal of the servo motor was measured instead of cutting force. The relationship was analyzed in detail and the mathematical models were created. The experiment system and the achievement means of the intelligent adaptive control are proposed. Practical experiments have proved that this indirect measurement is reasonable and has an important application value
