Did you ever have the control limit calculations compress your limits to the point you could barely run the process?  Have you run into Cpk values - either too high or too low, yet you felt the process was just fine?  Did you ever have an operator ask you about a reading that was out of specification, but the mean was in control?  These situations occur in precision machining frequently, and the problem is the distribution is not normal, but people are applying normal statistics and control charts to it and yielding wrong information.  CorrectSPC is a technique that busts the myth of the normal curve in precision machining.  It presents a technique that provides more information that is meaningful to the operator and the quality professional.  No transformations, no defects, no extra cost!
