Hi Paul, Where a manufactured part has 20+ features to be measured on CMM or vision systems. How should you go about implementing a SPC? Should you apply SPC on selective features only? Would you say using production gauges are outdated method for process inspection?

Hi ST - First thing you need to do is understand the Cpk for the 20 features, if the Cpk is good then maybe drop that from your SPC list, only concentrate where there is a risk of making defects. Gauges should be avoided or eliminated where possible...

Sathya - Many thanks for your comment, if you'd like to know more look up my book ' drink tea and read the paper on LULU. COM

Maybe there is nothing wrong with the machine, it could be you changed operators on the machine, human error is the number 1 problem in CNC machining. Process behavior is my operators not my machine, they are the problem as each has there own noise, machines don't have bad days people do, machines don't have fights with their wives or come in with a hangover and lose focus on the job. 40 plus years of experience tells me most problems in manufacturing comes down to the operator not the machine or tooling, its the operator, leave my setting alone and stop putting in the wrong inserts, learn how to read a micrometer and blueprint properly. When I find a process out of control the first thing I look for is something that the operator has done to change the process, 99.9% of the time this is the problem.

Michael - many thanks for the comment. If you've been seeing these problems for 40 years, you're going to take some convincing that you're wrong. But I'm just going to come out and say it, you're wrong, by a million miles, it's never the operator. I have no doubt that if I spent just 5 days with your operators we would eliminate all those problems you describe, for zero cost. Ask yourself, do you expect your operators to remember and know what they are doing? or do your systems of work make sure they always have explicitly instructions of what they should do. if you rely on skill, you're toast! If I turned up tomorrow, could I run your machine defect free with almost no training, because your systems of work are so obvious, I'd know what to do. If I get the chance I'm going make a video of what world class process control looks like....and I'll drop you a line when I've done it....
