Mailbag:<br>Gaging Improves Automatic Grinder Control
Dear Editor:
I would like to comment on a statement in the article "Gaging Improves Automatic Grinder Control" in April 2002 Quality. The statement deals with the Cpk and is found in the first paragraph of page 34. The statement is:
"A Cpk of 2.0 means that 68% of the parts will be +/- 33 millionths of an inch of nominal."
