Solution Overview

Problem

Existing NC machine tools cannot individually identify the processing time for each function command within a block of an NC program, making it difficult for operators to analyze and compare performance data effectively.

Innovation Solution

An NC machine tool with a display device capable of showing processing times for each function command, along with a memory section to store and compare data, and a calculating section to automatically calculate and compare processing times, allowing operators to identify individual command performance and detect abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple function commands are arranged in a single block of NC program, then the NC program becomes more compact and efficient, but the operator becomes unable to identify the processing time for each function command individually

Engineering Contradiction:

ImproveNC program efficiencyVSAvoidprocessing time information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent segments the processing time information by function command type, displaying the total processing time for each block along with breakdowns for individual function commands (T code, S code, G code, M code). This segmentation allows operators to see both the aggregated block time and the specific time contribution of each function command within that block, resolving the information loss while maintaining program compactness.

Inventive Principle:

Principle #1Segmentation

2Reliability

If processing time data is stored in memory section, then data can be saved and compared, but the device complexity increases

Engineering Contradiction:

Improvedata accuracyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control device's memory section is designed to serve multiple functions: storing current processing time data, storing reference processing time data, and enabling comparison between them. This multi-functionality allows the system to maintain reliable data without adding separate dedicated storage systems, thereby improving data accuracy while minimizing the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If the display device shows processing time for each function command, then the operator can identify individual command performance, but the display complexity and information overload increases

Engineering Contradiction:

Improvetime measurement detailVSAvoiddisplay structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The display device applies local quality by presenting different levels of information detail in different display areas or contexts. The block processing time is displayed prominently for overall monitoring, while function command-specific times are displayed in a detailed breakdown section. This allows operators to access precise measurement data when needed without being constantly overwhelmed by detailed information, effectively managing display complexity while maintaining measurement precision.

Inventive Principle:

Principle #3Local quality
