SPC (Statistical Process Control) is the statistical analysis of measurement data collected from a manufacturing process to determine its viability and make educated corrections to a process. SPC is an integral step in the production part approval process. Besides requiring a significant number of repetitive measurements (for which DCC-CMM’s are nearly indispensable) complex data compilation, analysis and interpretation are required. Q-PLUS routinely provides statistical results (such as Cpk, Cp, Ppk, Pp, Sigma level, etc.) supported by quantitative measurement data and depicted in a variety of graphical analyses.
Capability Studies provide a greatly enhanced examination and validation of manufacturing processes. These are commonly utilized in high-production applications such as automotive, components and commercial products. Q-PLUS provides many types and degrees of capability studies tailored to any application or special customer requirements.
An important component of any comprehensive capability study is analysis of the measurement process itself. A Gage R & R (Repeatability & Reproducibility) study is a common way to determine what amount of error in a process is due to measurement uncertainty.
PPAP or Production Part Approval Process is a standard requirement in the automotive industry that occurs at the beginning of or after a change to a manufacturing process.
