Solution Overview

Problem

There is no existing method for automatically generating a control program exclusively for diagnostic purposes for production machines or machine tools to determine mechatronic parameters of their feed axes, which are crucial for assessing machine performance and maintenance.

Innovation Solution

A method and device that automatically generate a control program using an algorithm based on freely selectable and machine-specific parameters, defining a travel profile with measurement runs to excite the machine axis, allowing for the determination of mechatronic parameters such as rigidity, friction, and backlash, creating a database for comparison and analysis.
