Solution Overview

Problem

Existing turret tool selection and command methods lack an efficient and flexible way to set offset numbers for tools mounted on turret surfaces through tool holders, making it difficult to select the required tools for processing.

Innovation Solution

An offset number setting device with a display system that includes turret surface selection, tool holder selection, and offset number setting screens, along with a data processor that processes information input through these screens, allowing operators to easily and freely set offset numbers for tools mounted on turret surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a predetermined tool is mounted on a tool holder mounted on a predetermined turret surface, then the tool can be selected based on tool number and turret surface number, but it becomes difficult to freely set offset numbers for various tools mounted through various tool holders

Engineering Contradiction:
Improveflexibility in offset number settingVSAvoiddifficulty in setting offset number
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically generates the offset number setting screen based on the selected turret surface and tool holder, allowing the interface to adapt to different tool configurations. This enables flexible offset number assignment for various tools mounted through different tool holders on different turret surfaces, resolving the contradiction between adaptability and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple tools are mounted on turret surfaces through various tool holders, then processing requirements can be met, but the complexity of setting and managing offset numbers increases

Engineering Contradiction:
Improveability to mount various toolsVSAvoidcomplexity of offset number setting system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by automatically generating the offset number setting screen with appropriate parameters based on the selected turret surface and tool holder. This preliminary setup reduces the complexity of offset number management by pre-configuring the interface according to the specific tool mounting scenario, allowing operators to focus on selecting offset numbers rather than configuring the entire setting system.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If offset numbers are set for each tool and turret surface combination, then tool selection accuracy improves, but the time required to set up and manage offset numbers increases

Engineering Contradiction:
Improvetool selection accuracyVSAvoidtime for offset number setting
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system uses the selected turret surface number and tool holder information as templates to generate the appropriate offset number setting screen. This copying approach allows the system to reuse and adapt existing configuration data, reducing the time required to set up offset numbers while maintaining accurate tool selection through the structured relationship between turret surfaces, tool holders, and offset numbers.

Inventive Principle:
Principle #26Copying

AI summary

This invention is concerning an offset number setting device that freely and easily sets an offset number for a tool (8) to be mounted on a tool holder (7) of a turret surface (6). A display linkage unit (19) displays a turret surface selection screen (20) on a display (12), displays a tool holder selection screen (29) on the display (12) by selecting the turret surface (6), and displays an offset number setting screen (30) on the display (12) by selecting the tool holder (7). An offset number is therefore set for the tool (8) along with the selection of the turret surface (6) on which the tool (8) is mounted.
