Dear Sirs,
this is my first time in this forum, and this is my first question.
Let' start. Our plant produce some kind of components for engine chains, one of these components are pins. After two stage of the production process, we check the surface roughness, the first after grinding process and the second after finishing process (tipically superfinish). We have in our STD the reference value for Ra - Rz - Rt, the cutoff and the filter to be use, but is not reported the sampling lenght.
We have pins with several lenght starting from 8mm up to 28mm; the question is: can we use the same sampling lenght for all the pins or is better to use a particular sampling lenght in functions of the lenght?
Thanx in advance.
Dario
