Machine Part Work Life
Machine Part Work Life
(OP)
Hello everyone,
I'm trying to determine the work life of various machine parts. I have tried contacting the manufacturer, but they do not have any information on the subject.
So far, I have started a database of dates when parts were changed, and then planning on getting an average amount of days a part was being used before it was changed. So far, my data is having a lot of variation.
Any advice on how to get more accurate data?
Thanks for the help.

RE: Machine Part Work Life
Were they actually replaced because they wore out from use or other factor - e.g. some components break down over time even if the machine is not being used.
What was their duty cycle, 24/7/52 or 8/5/47 or ....
Is their wear even through out use, or at certain stages do they see more wear e.g. at startup/shut down?
Are the machines all being used similarly e.g. a tool operating at 10% capacity may last longer than one working at 100% capacity in any critical spec.
Even if you got a massive amount of data of how long between changing parts, if the relevant usage conditions aren't taken into account, it's difficult to come up with a good life estimate. Best you could take a conservative value e.g. 5th percentile and use this as 'typical life dependent on usage conditions' or something.

RE: Machine Part Work Life
As stated by KENAT tool life can vary greatly depending on many..many factors (variables)..
RE: Machine Part Work Life
It would also help if you told us what type of machines they were. Are you dealing with conveyors, loaders, milling machines, lathes, bearings, motors etc.
The type of machine greatly affects the duty cycle.

You are judged not by what you know, but by what you can do.
RE: Machine Part Work Life
If it is machine tools that would be close to impossible to determine. Why, because too many variables, like are you using the default speed parameters or did you speed them up or slow them down? What kind of loads are you putting on the machine? What kind of materials are you cutting on the machine? What coolants are you using? What are the conditions in the shop? If you want to know how long your machines will last, start calling on other shops that use the same types and brands of machines, and you will get a good idea.
