Portable position error amendment manner and portable position error amendment verification manner null of NC

摘要

PURPOSE: To make a fine moving position correction into the one with high accuracy and to properly perform a moving position correction even for a moving position error including a dynamic error factor by performing a moving position error correction based on calculated dynamic position error amount. ;CONSTITUTION: NC program execution part 9 of an NC device 7 executes an NC program and outputs a moving command to a driving control part 11. The driving control part 11 controls the rotation control of a servo motor 3. The moving command for the measurement of the moving position of this machine is also outputted to a dynamic position error arithmetic computer 25. The dynamic position error arithmetic part 29 of the dynamic position error arithmetic computer 25 calculates dynamic position error amount by the difference of the machine positional data of a command value data storage part 27 and the measured value data of a measured value data storage part 28. Further, a moving location error correction arthmethic computer 31 calculates the moving position error correction value based on the dynamic position error amount and outputs the correction value data to the correction arithmetic part 33 of the driving control part 11. Namely, dynamic position error amount data is converted into moving position error correction value data.;COPYRIGHT: (C)1996,JPO
