4. Inspection Items & SPC Analysis

Once the quality data is fully and automatically collected, all the data is stored in our SPC system, each inspection item can generate a complete SPC analysis report with a single click, including:

• Appropriate control chart selection and subgroup distribution
• Process Capability Analysis Report
• Cpk, Ppk, PPM
• Distribution charts and fitted curves
• Normal probability plots and capability comparison charts
• Normality tests and distribution fitting tests
• Machine-learning-based anomaly detection charts
• Statistical summary tables and capability tables
• Raw data details and rainbow charts
• Historical out-of-control events and corresponding improvement actions

• Identify quality differences across products, machines, lines, or stations

Batch Export of SPC Reports

• Select multiple inspection items at once
• One-click batch export of SPC analysis reports to Excel
• Significantly improves reporting and analysis efficiency

Large Language Model (AI) Support

• Integration with public large language models
• Supports private LLM deployment, such as DeepSeek
• AI-assisted quality analysis, anomaly interpretation, and improvement support

5. SPC Dashboards

As manufacturing digitalization advances, dashboards are widely used on the shop floor to produce production status, such as order progress and workstation load.

Quality management follows the same visualization approach by：

• Deploy real-time SPC dashboards at any production station or line
• Monitor quality anomalies for specific workstations, lines, or orders

Dashboard Capabilities

• Unlimited number of dashboards
• Unlimited charts per dashboard
• Each dashboard has a dedicated URL, ideal for large-screen displays
• Supported visualizations:
• SPC control charts
• Pre-control (rainbow) charts
• Capability histograms
• All charts update in real time

Dashboard Types

1. Real-time dashboards
2. Comprehensive dashboards
3. Statistical dashboards and custom charts

6. SPC Monitoring & Alerts

1）Monitoring Configuration

The anomaly detection item list notification has been upgraded to allow configuration of different notification object groups based on the detection item category.

2）Alert Capabilities

3）Flexible alarm rules

4）Alarm lists and alarm history

5）Email notifications

6）Enterprise WeChat notifications

7. Data Collection Methods

Manual Entry

• SPC control charts are updated instantly in real time upon manual data entry.

Multi-Item Entry

• Enter multiple inspection items simultaneously, even with different data types

Excel Batch Upload

• Batch upload inspection data using a specified template.

Mobile Data Entry

MQTT Data Acquisition

• Collect real-time data from inspection and production equipment via MQTT

HTTP API Integration

• Synchronize data from existing business systems without re-entry

Active JSON Data Collection

SAP Inspection Plan Synchronization

8. Advanced Analysis Tools

We often need to periodically analyze SPC process data for various testing items, or compare process data from different testing items. A fast statistical tool is essential.

SPC Historical Analysis

• Analyze SPC data by configurable time periods

ü  Define start and end dates

ü  Aggregate by year, quarter, month, week, or day

• Select key metrics such as Cpk and number of rule violations
• Compare multiple inspection items
• Export results or visualize using charts

Box Plot Analysis

• Generate box plots for individual data at fixed time intervals

Correlation Analysis

The SPC system stores a lot of testing data. Some testing items from common sources may be correlated. Generally, we organize this testing data and use Minitab or Excel to perform correlation and regression analyses in pairs, adjusting the lag period to find the optimal antecedent effects. However, a more efficient method is essential:

• Perform scatter plots and regression analysis across multiple inspection items
• Align data by inspection dates
• Define lag ranges to automatically identify preceding effects
• No need to export data to Excel or Minitab—analysis is completed within one system
• Traverse N inspection items × M lag periods to identify correlated test items.

Cpk Tool

• Perform SPC control charting and capability analysis without creating inspection items
• Supports individual and subgroup data
• Paste data directly from Excel
• Replaces traditional control chart and capability analysis functions of Minitab

Regression analysis

ANOVA

• Normality tests
• Distribution fitting
• One-sample t-test
• Two-sample t-test

9. MSA Support

• Gage linearity and bias studies
• Gage R&R (nested)
• Gage R&R (crossed)
• Attribute consistency analysis

10. Application Cases

1） Mettler-Toledo Checkweighers

This is an automatic weighing device. Each weighing sends weight data via a TCP server. We developed a small program：

ü  Custom TCP client collects and synchronizes data to SPC system for real-time analysis

2） Bluetooth Micrometers

3） Quality Dimension in Production Scheduling

ü  Different sources (machines A or machines B, shifts, lines, operators, etc.) tracked separately

ü  Cpk comparison across sources

ü  High-priority customers assigned to higher-Cpk production sources (the image below shows machines A and B).

4） Proactive Data Acquisition from DCS Database

ü  Large amounts of data have been collected in the data center. Data is directly linked to the database and synchronized to the SPC software.
