Process capability refers to the ability of a production process to consistently produce products that meet quality requirements under stable and fixed production conditions. To understand process capability, there are at least two key aspects we need to consider: A … Continue reading →

Workingbear has already spent a good amount of time explaining what Cp (Precision) and Ck (Accuracy, sometimes called Ca) mean, and what each represents. We’ve also learned that using Cp or Ck alone can give an incomplete picture when it … Continue reading →

What Is Ck or Ca? Ck, which some people now refer to as Ca (Accuracy), represents how close a process output is to the target value. Using a target-shooting example: if someone fires six bullets and all land near the … Continue reading →

Understanding Cp as a Process Capability Indicator Cp (short for Precision) is a measure of how tightly a process is centered and how consistently it produces results. Using a target-shooting analogy, if someone fires six bullets and they all hit … Continue reading →

Cpk is commonly used as an overall indicator of a factory’s manufacturing process capability. However, it can also be applied across different industries to measure the ability to meet a target. A popular analogy is how well you can hit … Continue reading →
