Predictive Maintenance Suggestions

[harry]

My question is: just because predictive maintenance is mentioned in the TS documents, does it mean that every body must practice it or show evidence that it is being practiced?

While I understand that it is basically a 'good practice' but at times it may not be applicable in a low tech. environment such as manufacturing of wire harness where simple machines for cutting, crimping and testing are employed. (in other words, traditional preventive maintenance is good enough)

Thanks in advance for sharing your views.

Re: Suggestions for Predictive maintenance

What are the other techniques. The three you listed are the only three that we hear about and it is really not cost effective based on the equipment that we have. We do not have rotating equipment, we don't have hydraulic fluids and very little mechanical equipment.

Sorry. I didn't have time earlier to get back with you.

Some additional methods include dynamic current monitoring of motors, continual monitoring of temperature for gradual increases, continual monitoring of pressure or pressure drop (as filters clog), ultrasonic, and performance trending.

In answer to you question Harry:

The requirement for Predictive Maintenance is a Shall and therefore you must do it.

Section 7.5.1.4 "The Organization shall utilize predictive maintenance methods to continually improve the effectiveness and the efficiency of production equipment."

Therefore the focus should be on production equipment, and you must show evidence that even low tech items have predictive maintenance performed.

It is a good question and did make me look at the specification to ensure I wasn't missing anything.

Couldn't something as simple as visual inspection be a part of predictive maintenance? Between shifts someone goes around and looks at the equipment for signs of wear and tear. Items that are questionable are watched more closely, or are replaced immediately.

I think the system belongs to the owner who runs the business, as such whether Predictive Maintenance is practical for the owner is at his discretion base on his cost and benefit analysis.

I agree that simple routine preventive maintenance's resulta contribute to the predictive maintenance decision. If the components found to fail soon can be replaced readily without causing disruption to quality and delivery to customer, I think it is less critical to practice predictive maintenance here.

I agree, predictive maintenance is good to practice when components of machines are not changed before it fails as it could cause the owner to incur most cost, but not for those with easy replacement of components and quick repaired machines. If this is already acceptable in TS audit, please enlighten me, thank you very much!

As such, I wonder whether TS Standard would consider revising some of the requirements to be more flexible, of course it will then depend on competence of auditor to judge whether the practice of the owner is complying to the intent of the Standard; and I think auditor is and should play this role, instead of follow the standard without critical assessment of the Standard requirement and its applicability.

Please pardon me and correct me for me to learn more, thank you very much!
