Example of Capability Analysis Data
• For some critical dimensions we need to measure more than 1 part • For capability data we usually measure 5 pcs 2 times/hour=100 pcs

–Causes that are implemented in the process
due to the design of the process, and affect all outcomes of the process

• Process Capability is designated by Cp and Cpk
• Process Performance is a measure of the performance of a process to be able to consistently produce components that meet the required design specifications. Process Performance includes special causes of variation not present in Process Capability

Two Types of Processes
• All processes have:
–Natural (random) variability
=> due to common causes
–Unnatural variability
=> due to special causes
These parts are out of spec and could be approved if only one good part was measured
A process capability study would reveal that the tool should not be accepted

Process Capability - What is it?
• Process Capability is a measure of the inherent capability of a manufacturing process to be able to consistently produce components that meet the required design specifications

• All processes have: –Natural (random) variability => due to common causes
Variable: A characteristic measured in physical units, e.g. millimetres, volts, amps, decibel and seconds.
Attribute: A characteristic that by comparison to some standard is judged “good” or “bad”, e.g. free from scratches (visual quality).
