Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing machines, such as grinding machines, face difficulties in specifying complex delivery functions due to the need for precise numerical input, which requires user experience and is prone to errors, limiting the ability to achieve desired workpiece accuracy.
Innovation Solution
A method and input device that utilize a graphical representation to define and modify delivery functions, allowing users to input and adjust feed curves using a computer mouse or similar pointing device, simplifying the process and reducing the risk of errors by enabling visual manipulation of the machining process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If numerical values are entered to define delivery function parameters, then manufacturing precision can be achieved, but ease of operation deteriorates due to complexity and error-proneness
Solution Approach 1:
The patent replaces manual numerical input (mechanical/digital entry) with graphical interaction using a mouse to manipulate visual elements. Users drag and drop graphical representations of delivery function parameters instead of typing numbers, substituting complex data entry with intuitive visual manipulation while maintaining precision through the system's underlying numerical processing.
Solution Approach 2:
The patent introduces graphical elements as intermediaries between the user and the numerical delivery function parameters. These visual representations serve as mediators that users can easily manipulate, which then automatically translate into precise numerical values for controlling the movable tool, bridging the gap between user-friendly interaction and precise control.
2Manufacturing precision
If complex delivery functions are specified using numerical input, then manufacturing precision can be maintained, but device complexity increases due to programming requirements
Solution Approach 1:
The patent replaces programming-based configuration with graphical interaction. Instead of requiring users to write or edit code to define complex delivery functions, the system allows users to visually construct and modify delivery functions by manipulating graphical elements, eliminating the need for programming while maintaining full functionality.
Solution Approach 2:
The patent uses graphical copies or visual representations of delivery function parameters that can be manipulated without affecting the underlying numerical data structure. Users work with visual copies that automatically update the actual control parameters, separating the complexity of numerical processing from user interaction.
3Adaptability or versatility
If numerical values are manually entered, then flexibility in specifying delivery functions is limited, but ease of operation improves by avoiding graphical interfaces
Solution Approach 1:
The patent makes the delivery function specification dynamic and adaptable through graphical manipulation. Users can easily modify parameters by dragging graphical elements, adding or removing control points, and adjusting curves visually, allowing the delivery function to adapt flexibly to different machining requirements without being constrained by fixed numerical input formats.
Solution Approach 2:
The patent introduces graphical elements as intermediaries that enhance flexibility. These visual representations allow users to easily experiment with different delivery function configurations by manipulating graphics rather than rewriting numerical data, making the system more adaptable to various machining scenarios while maintaining ease of use.

AI summary
The method involves displaying an initial feed function in the form of an initial feed curve (30,30') on a monitor (11). A feed function is calculated from the initial feed function and from inputs effected by a pointing device. The feed function is displayed as a modified initial feed curve on the monitor. Control commands are produced for moving the tool from the feed function. Independent claims are also included for the following: (1) an input device for implementing a method for controlling a movable tool by a feed function (2) a machine tool with a measuring device for acquiring measured variables during machining of a workpiece (3) a computer program for running the method on a computer (4) a data medium for storing the computer program.
