Abstract

A method for the computer-assisted control of a machine or a process using a process computer connected to the machine, installation, or the like via an interface, a monitor connected to the process computer for the graphic display of the machine or process cycle, and an input device, preferably in the form of a keyboard, for programming a control or predetermining set values, the control being based on a machine or process-specific flow chart, is designed to take account of the real-time behavior of a machine or a process such that the programming of the control process or the predetermination of the machining steps proceeds from vectors and/or curves, and that the real-time behavior of the machine or process is considered in that the machining steps and thus the individual movements are converted by including the machine and process-specific data into the form of a process-linked polygonal course.

Dependent claims

A method for the computer-assisted control of a machine cycle using a process computer connected to a machine via an interface, a monitor having a screen connected to the process computer for graphic display of the machine cycle, and an input means for programming the process computer, the method comprising the steps of:

determining a machine specific flow chart for the machine cycle based upon machining steps of the machine, including individual movements and operations of the machine, during the machine cycle, said machine specific flow chart representing time behavior of the machine during the machine cycle;
identifying process specific parameters based upon machining steps to be performed by the machine during the machining cycle for a specific machining process;
determining a first set of values for the process specific parameters, said first set of process specific parameter values being based upon the machining steps to be performed by the machine during the machining cycle for a specific machining process;
generating a plurality of vectors or curves based upon the machine specific flow chart;
converting the plurality of vectors or curves, utilizing the first set of process specific parameter values, into the form of a connected course;
linking the connected course to the machine;
displaying a graph of the connected course on the monitor as a function of at least one of path and time portions of the machine during the machine cycle;
controlling the machine based on the connected course displayed on the monitor during the machine cycle;
determining a second set of values for the process specific parameters based on the controlling step;
and
graphically superimposing the second set of process specific parameter values based on the controlling step on the screen upon the first set of process specific parameter values.
