| Abstract: | The machining accuracy for typical measuring and control system(numerical control lathe) is analyzed by the concept on uncertainty for entropy method.With the mathematical model for knifepoint-position servocontrol established,the uncertainty for entropy method about B class and A class of knifepoint position are gained,then dynamic entropy-method patulous uncertainty formula is educed.The precision theory and its application based on entropy concept is expressed concisely and concretely by this formula. |
