Statistical Process Control Implementation in Weaving
topic
Statistical process control implementation in weaving applies control charts including X-bar-R charts for continuous process parameters, p-charts for defect proportion, and c-charts for defect count per unit to monitor process stability and detect parameter drift before it causes quality failures, with control limits set at three standard deviations from the process mean distinguishing common cause variation that is inherent in the process from assignable cause variation indicating a specific process change requiring investigation.
Role
Provides the statistical monitoring infrastructure for detecting process parameter changes before they produce fabric quality failures, with SPC being the quality management tool that converts the reactive quality management of inspection-and-rejection into the proactive management of parameter monitoring and control that prevents defect generation, requiring both the measurement systems to observe process parameters and the organisational commitment to investigate and respond to statistical control signals before quality failures occur.
