Control Chart

The Control Charts are graphs which is used to check the quality of control of a process. In
Control charts UCL/LCL or USL/LSL will be used to check with the resultant
data.If Measurement data within the range of limits then the process is
OK(GOOD) .If the Measurement data is above or below the Limits
the process is NG(NOT GOOD).

1) OK (GOOD) -> USL <= Measurement Data >= LSL

2) NG (NOT GOOD) -> Upper Range -> Measurement Data > USL

3) NG (NOT GOOD) -> Lower Range -> Measurement Data < LSL
