Abstract: PURPOSE:To improve accuracy of numerical control by making information value on a tape greater than the value in the minimum control unit by one digit, and reducing said value to 1/10 in the actual control, and adding the remainder to the value of next tape information. CONSTITUTION:Data of a sensor, an actuator etc. are recorded in an NC tape to a value which is greater than the minimum control value by one digit. When instruction to start an NC controller is sent out, the controller reads the numerical value from the NC tape and adds the remainder (0 when starts) in the buffer to the value in adding process. In dividing process, the value obtained by addition is divided by 10 to make the numerical value a value corresponding to the capability of the sensor, actuator etc. and the remainder is inputted to the buffer. In arithmetic controlling process, an actuator signal is outputted, and the same process is repeated through discriminating process 4. By this way, accuracy of numerical control can be improved without improving the accuracy of the sensor, actuator etc.
