Cp vs Cpk vs Pp vs Ppk: choose the right variation estimate
Worked capability examples explain centering, within-subgroup versus overall spread, and the checks needed before interpreting an index.
Industrial AI
Machine learning and AI applied to manufacturing and process data.
Vibration condition monitoring: from sensor placement to fault frequencies
A practical guide to vibration monitoring — accelerometers, mounting, ISO 10816 zones, envelope analysis, and the fault frequencies that name the failure.
Statistical process control: control charts that catch drift early
Apply SPC where it works — control chart selection, rational subgrouping, capability indices, and the reaction plans that turn charts into control.
Predictive maintenance starts with signal quality
Sampling, timestamps, operating context, labels, and work-order feedback matter more than choosing a sophisticated model too early.
Industrial AI pilot checklist: from promising demo to useful shift tool
Choose the decision, build a baseline, validate data and labels, design the human workflow, and measure whether the pilot changes plant outcomes.
Edge versus cloud analytics in industrial operations
Use latency, availability, bandwidth, data gravity, and governance to decide which analytics belong beside the machine and which can travel farther.
The predictive maintenance data stack, end to end
From vibration sensor to work order: sensing, transport, context, models, and the analytics layer where predictions become decisions.
Machine vision on the factory floor: the basics that decide projects
Optics, lighting, and pass/fail discipline matter more than the algorithm. A practical map of inspection, guidance, and identification.

Terms in this topic
- Control limits
- Statistical boundaries calculated for a control chart under its chosen sampling model.
- Rational subgroup
- A sampling group designed so within-group variation represents the short-term variation being studied.
- Sample standard deviation
- A measure of observed spread using squared deviations from the sample mean and an n−1 denominator.
