DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a method of and an apparatus for monitoring and programming the functioning of a machine for machining workpieces, in particular, a spark erosion machine. The apparatus of the invention is provided with a screen with a window, and the invention also relates to the screen window.
Presently, it is customary to carry out monitoring and programming of the functioning of a machine for machining workpieces by using a control apparatus having a screen with a main window with actual conditions of machining of a workpiece being shown on the window screen. Specifically, with spark erosion machining, defining data such as, e.g., the gap width, tensioning, etc. . . are flashed on the screen in small value fields. It is further customary, in particular with spark erosion machining, to display on the screen separate points of a profile to be cut in the workpiece in accordance with point inputs. The inputs of the points are effected in accordance with desired movement of the wire electrode. When this technique is used, the user should input, next to a respective point, corresponding directional data. Because of such an input, only a limited dialog between the user and the screen is possible. To be able to verify whether the inputs of predetermined points lead to a desired profile, the user should simulate the complete course of the wire electrode along the profiled section. That is why an initial erroneous input of a cutting direction, e.g., often leads to a non-executable profile. However, finding out that the profile is erroneous occurs at a much later time. Because expenditure of time for input of points based on erroneous data is rather considerable, undesirable dead time results.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a method and an apparatus for monitoring and programming the functioning of a machine for machining workpieces, so as to improve the dialog between the user and the apparatus.
This and other objects of the invention are achieved by providing a method and an apparatus for monitoring and programming the functioning of a machine for machining workpieces, in which separate functions are displayed, one after another, in the window of the apparatus screen, and one or more of the displayed functions is/are selected, and/or displayed valuewise in a further window of the screen. Thus, selection of a function and its valuewise display can be controlled. In a further embodiment of the invention, the screen window is provided with a window header section for function identification, a window input section for displaying set up values, a window sketch section for displaying and controlling the influence of the set up values on the function, and a key section with which the process of the function set up is broken or interrupted, or the function is transferred to the main window, or constructional alternatives are supplied.
According to an advantageous embodiment of the method of the invention, only executable functions are released for selection, with the corresponding apparatus having means for blocking selection of non-executable functions. Therefore, the user can never select a function which cannot be executed during the course of machine operation. Thus, an erroneous input of a non-executable function, made consciously or unconsciously, is prevented. Advantageously, executable and non-executable functions are distinguished from each other. The apparatus according to the invention includes at least one activating element, preferably provided with identification symbols and associated with the screen window for selecting at least one of the displayed functions. To this end, the activating element is preferably provided with an icon, advantageously, with an icon menu. More preferably, the activating element is provided with means, specifically, a luminous or color defined section, for observable distinction between the executable and non-executable functions. In this case, the user can immediatly recognize
