Solution Overview

Problem

Machine tools with integrated operator control units face limitations in expanding data availability due to safety and operational constraints, preventing the display of comprehensive information directly on the machine tool, requiring operators to access workstations for machining and workpiece data.

Innovation Solution

The integration of an operator support system that connects to a data network, allowing access to processing and workpiece information, design data, and order information, with a visualization unit positioned adjacent to the machine control unit, enabling direct display of data on the machine tool and allowing for virtual control of machining units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the machine control is expanded to provide more data and information, then the operator can access more processing and workpiece information directly on the machine tool, but the machine control cannot be expanded due to safety and operational constraints

Engineering Contradiction:
Improveavailability of machining and workpiece informationVSAvoidexpandability of machine control
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The system is divided into two independent parts: the machine control unit that maintains safety and operational independence, and the operator support system that provides expanded information access. The operator support system includes a data processing unit connected to the data network and a visualization unit for displaying information, while the machine control unit processes CNC records and generates control commands separately. This segmentation allows each unit to fulfill its specific function without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The operator support system acts as an intermediary between the data network and the operator. It receives machining and workpiece information from the data network via the data processing unit, processes this information, and displays it through the visualization unit. This intermediary role allows the operator to access comprehensive information without requiring the machine control unit itself to be expanded or modified.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the operator accesses information from a data network, then comprehensive machining and workpiece information becomes available, but the operator must leave the machine tool and go to a workstation

Engineering Contradiction:
Improveaccess to machining and workpiece informationVSAvoidtime spent leaving and returning to machine tool
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The operator support system merges the information display functionality with the machine tool interface. The visualization unit is positioned on or near the machine control unit, allowing the operator to view machining and workpiece information directly at the machine tool location. This combining of information access and machine operation in one location eliminates the need for the operator to travel to separate workstations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The operator support system provides self-service information display by automatically receiving and processing data from the data network. The data processing unit continuously accesses machining and workpiece information, and the visualization unit automatically displays this information without requiring the operator to manually navigate to external systems or workstations.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the visualization unit is permanently positioned, then it is always accessible to the operator, but it becomes spatially disruptive on the machine control unit

Engineering Contradiction:
Improveaccessibility of visualization unitVSAvoidspatial arrangement on machine control unit
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The visualization unit is designed with dynamic positioning capabilities, allowing it to be moved between different positions. It can be positioned in an active state where it is accessible to the operator and in an inactive state where it is covered by the machine control unit housing. This dynamic positioning allows the system to adapt to different operational requirements without creating permanent spatial disruption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The visualization unit can be positioned within or adjacent to the machine control unit housing, effectively nesting the display function within the existing structural envelope. When not in use, the visualization unit can be covered by or integrated into the housing structure, minimizing its spatial impact while maintaining accessibility when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The tool has a machine control determining control commands for operations of machining units and controlling a drive of the machining units via a drive control, using the control commands. An operator support system (200) is arranged on the tool, and works independently of the machine control. The operator support system is connected to a data network (350) via which machining and/or workpiece information (352) is accessible. The operator support system comprises a visualization unit (210) for representing the machining and/or workpiece information. An independent claim is also included for a method for machining a workpiece according to a computer numerical control (CNC) machining program package.
