Abstract
There is provided a method and device which extracts as a running operation history a modification made to an NC program for numerical control of machine tools which has already been completed. After making an NC program, modifications are made to the NC program prior to the actual operation so that experience in field work or results of test machining can be reflected. An optimum NC program can be obtained through such modifications, and contents of the modifications are extracted from the NC program as a running operation history to produce a data base. The running operation history data base is reflected in subsequent preparation of NC programs having similar conditions.
