Method and machine system for controlling an industrial operation

Abstract

A method for selecting optimum operation performance criteria for a metal working process. The method includes the step of developing a process model relating process parameters for the operation with performance variables for said operation, wherein the process parameters and performance variables are retrievable via integrated multiple data sources, and selecting at least one optimization technique to define a function, said function including process parameters. Moreover, the method includes generating the function for optimization by using acceptable tolerances of a product to be machined as a basis to define ranges for performance variables along with ranges for process parameters, and applying the at least one optimization technique to said function, whereby optimum operation performance criteria are calculated for the process model including process parameters and performance variables to obtain a set of requirements to be used for controlling the metal working process.

Description

TECHNICAL FIELD[0001]The present invention relates to a method, an industrial machine system, a computer program product and a non-transient computer-readable medium for selecting optimum operation performance criteria for controlling an industrial machining operation, such as a sheet metal working process.BACKGROUND ART[0002]Industrial machine systems of today typically consist of a machine with an actuator system for providing relative motion between a machine part or operating device and a workpiece. State of the art industrial machine systems are highly specialised to perform operations like for instance beam cutting, milling, turning, drilling, boring, punching, punch pressing, press-breaking, bending, welding and assembly operations. The machine system is a substantial investment to most potential customers, in particular to smaller or medium-sized workshops, why the versatility and productivity that the machine system is to contribute with to the business is a key factor when...
