SPC and heat-treatment software for the quality engineer
SPC LIVE MACHINE turns your measurements into control charts with Cpk and Ppk. The Heat Treatment Contraction Tracker replaces the handwritten adjustment sheets a plant keeps for each SKU with a library built from the plant’s own measurements.

One-time purchase
Instant SPC visibility while you’re making parts
Manually enter numeric measurements (e.g., dimensions) or categorical checks (e.g., pass/fail) during production runs, and see real-time status as you go. The Operator Screen is designed as a single-screen workspace (no scrolling) with a clear status banner so the operator can stay focused.
Automatic control limits + rule-based alerts
The app automatically calculates control limits using the moving range method and detects key SPC rule violations (e.g., values outside limits, runs like 8 points on one side, sudden changes). Alerts are color-coded for clarity (blue waiting, green OK, amber warning, red critical) so issues stand out immediately.
Built-in actions, traceability, and supervisor-ready reporting
When an alert fires, the operator must acknowledge it and document the action taken (e.g., tool change, process change, material change, operator change, no action, other), with the control chart visible at the moment of decision. Supervisors get a dashboard to review data, view X and mR charts, track events/alerts, and export CSV reports.
Frequently asked questions
What is SPC LIVE MACHINE?
It’s a mobile quality control application for manufacturing environments that supports real-time monitoring using SPC methods for one workstation or device.
What data can operators enter?
Operators can enter numeric measurements (like a dimension) and categorical checks (like pass/fail) during production runs.
How are control limits calculated?
The app calculates control limits automatically using the moving range method.
What triggers an alert?
Alerts trigger when SPC rule violations are detected, including defects, values outside control limits, runs such as 8 points on one side, and sudden changes.
What happens when an alert triggers?
The operator must acknowledge the alert and document what action was taken; the Action Screen displays the relevant control chart and supports deleting the last part if needed.
Can supervisors review results and export data?
Yes—supervisors can review all data, view control charts (including X and mR charts), and export CSV reports from the supervisor dashboard.
How do we set up a job and variables to monitor?
Use the Job Setup Screen to define job parameters (Job ID, Part ID, Machine ID, etc.) and add variables (numeric with LSL/USL limits or categorical with two choices); numeric variables use a dedicated screen to enter spec limits before data entry begins.
Does the operator screen show capability metrics?
Yes—the Operator Screen includes a limits panel showing UCL/CL/LCL and capability indices Cpk/Ppk.
Heat Treatment Contraction Tracking
Track and analyze material contraction through heat treat cycles with statistical precision.
Replace adjustment sheets with a validated contraction library. Protect your institutional knowledge when a 20-year operator retires, material/vendor changes, or a tolerance is revised.

- Before/after normal distribution charts per SKU
- ±3σ percent-change curves for every SKU
- CSV batch processing of historical data
- Replaces handwritten contraction sheets permanently
