AI Technical Summary

Technical Problem

Current machines for processing plasticizable materials face challenges in operating at an optimal working point that balances productivity, energy requirements, and application rate, often requiring manual parameter input and specialist knowledge, which is not feasible due to a shortage of skilled operators and increasing complexity.

Method used

A procedure that determines machine-specific adjustment parameters and machine-independent process parameters through an iterative simulation process, allowing machines to operate at a process-phase-dependent optimal working point without manual parameter input, using machine-related mathematical models and engine characteristics to optimize productivity and energy efficiency.

Benefits of technology

Enables trouble-free determination of optimal machine settings, reducing energy waste and tool wear, and simplifies the operation of machines, allowing for shift operations without the need for skilled personnel, by automatically adjusting parameters for optimal performance.

Abstract

The invention relates to a method for setting up and operating machines for processing plasticisable material, comprising at least one electric motor for at least one machine shaft, the motor characteristics of which, in particular a torque speed characteristic, being present as parts of a machine-related mathematical model (190). In the method, machine-independent process parameter profiles of an ideal filling process are determined from a filling simulation (200) taking into account the domains of tool (10) and material (Mat). In the process, in a simulation, machine-specific setting parameters and machine-independent process parameters of a real filling process are determined in an iterative approach process based on the machine-independent process parameter profiles of the ideal filling process and the machine-dependent mathematical models (190). During setup of the machine, machine-specific setting parameters can be at least partially taught by an operator and the machine is operated based on the determined and optionally taught machine-specific setting parameters and determined machine-independent process parameters without manual parameter input in a process-phase-dependent optimal working point (AP) of a filling process.
