English term
a normal distribution of randomly occurring damage
English to Japanese
Tech/Engineering
Mechanics / Mech Engineering
The phrase appears in an instruction manual of coolant recycling equipment. I have no idea what "a normal distribution of randomly occurring damage" is. Any suggestions and/or hints are welcome.
P.S.
The following is a part of the paragraph which contains the above phrase.
****************************************
In machining, all particles should be filtered that are larger than 10% of the tightest dimension specified. A reduction in the amount of coolant filtered allows tighter filtration. These additional costs are harder to quantify on a general basis but impact each process based on the delta between a plot of a wear line and a normal distribution of randomly occurring damage.
Thank you in advance.

Difficult to explain, but I'll try...
"Normal distribution of randomly occurring damage" means basically any unknown problems that would diminish the health or quality of any object quicker than normal wear. An example of "normal distribution of randomly occuring damage" to a car would be a collision. It's random and unexpected, but may happen regardless.

My client explained to me as follows; their explanation also helped me a lot.
*************************************
Given enough random events, the results can be plotted and will always give
some variation of the normal distribution curve - also known as the bell
curve. For example, if you roll two dice, sometimes you will get a two and
sometimes you will get a 12, but most often you will get a 7.
Mechanical components will exhibit a wear pattern. When the wear surfaces
are measured and plotted, you will have an "break in" period or rapid wear,
a long period of gradual wear, and then accelerated wear to failure.
Therefore, the occurrences of failures between the bell curve and the wear
line is wasted usage due to uncontrolled, random failures - mostly due to
heat in the metal cutting process.
