How do you measure surface finish
WebThe surface profile depth must be compatible with the total coating system thickness; typically, the thicker the coating system, the deeper the surface profile. For example, a 3-coat 15 mil system may require a 2-3 mil surface profile, while a 40-mil coating system may require a 4-5 mil surface profile. The maximum achievable surface profile is ... WebIn general, when measuring warpage or waviness using a coordinate measuring machine, the probe will contact four or more corners on the measured surface of the target. For example, in the case of a plate, generally six to eight points are collected.
