Estimating the term…
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.
A running operation history collecting device in NC machining comprising:
Running operation history collecting method in NC machining comprising:
A medium in which a program is recorded to execute a running operation extracting procedure for extracting, every step a work element is machined, running operation performed at the time of a machining operation using an NC program and/or a machining condition modified resulting from said running operation and to execute a running operation storing procedure for generating a know-how database for use by NC machines by storing, every step the work element is machined, in a rewritable manner said running operation and/or said modified condition, either or both of which are extracted.
