<font color=#0011dd>Could some body explain how is it possible to have a good Cp and Cpk values in this condition.</font>

From Cpk.pdf in the FTP portion of this site:

Calculation of predictable process capability indices is dependent on the statistical control of the process. If the process is not in statistical control, then the results of the study are subject to fluctuate unpredictability.
