DIALOGUE-ORIENTED PROGRAMMING SYSTEM FOR A CNC MACHINE TOOL

摘要

A dialogue-oriented programming system for producing and altering control programs for a CNC machine tool, having a data entry and visualisation device for entering and/or altering and simultaneously displaying data which represent the machining process sequences of the desired function and control sequence of the CNC machine tool, individual processes of these machining process sequences being able to be represented by means of symbols and blocks correspondingly connected to each other and being identified by means of marks and being able to be altered in accordance with the desired function and control sequence of the CNC machine tool, in terms of its sequence with time; a central memory and processing unit, in which the entered data are processed into NC control data for a machine control system of the CNC machine tool and the control data are output as control program for the CNC machine tool, to its machine control system, via an input/output unit; the programming system is further developed by a program editor unit in the central memory and processing unit, in which the entered data are connected to and processed with current parameters and application units to describe the dialogue sequence and the NC control program for the CNC machine tool; a database in which the entered data from the program editor unit are stored together, the database being subdivided into a region for machine control data and a region for dialogue control data of the programming system; a data control unit which carries out the access to the machine control data and the dialogue control data of the programming system in the database and their administration and is equipped for the selection of partial data stored in the database; a synchronisation unit, connected to the data control unit, for the matching of partial systems and for the fixing with respect to time of machining process sequences of the partial systems; sequence data and partial data selected by the data control unit being created, in the control program for the CNC machine tool, in the form of a synchronisation framework which can be supplemented by processing steps or machine program sets; and a feedback unit, connected to the data control unit, accesses the control program for the CNC machine tool and uses state information from a simulation run of the control program for the insertion, deletion or shifting of the marks.
