Rvm (ASME) – Average Valley Depth per ASME

Rvm is the average valley depth of the roughness profile, as defined in ASME standards. It reports the valley or dale depth excluding noise, dirt, odd scratches, etc., that aren’t part of the surface we care about. The same calculation can be performed on the waviness profile (Wvm) or primary profile (Pvm). Rp, Wp, Pp, … Read more

Rv (ISO), Wv (ISO), Pv (ISO) – Average Valley / Dale Depth per ISO

Rv is the average valley depth of the roughness profile, as defined in ISO standards. It reports the valley or dale depth excluding noise, dirt, odd scratches, etc., that aren’t part of the surface we care about. The same calculation can be performed on the waviness profile (Wv) or primary profile (Pv). Rp, Wp, Pp, … Read more

Rpm (ASME) – Average Peak Height per ASME

Rpm is the average peak height of the roughness profile, as defined in ASME standards. It reports the valley or dale depth excluding noise, dirt, odd scratches, etc., that aren’t part of the surface we care about. The same calculation can be performed on the waviness profile (Wpm) or primary profile (Ppm). Rp, Wp, Pp, … Read more

Rz, Wz, Pz – Average Peak to Valley Height

The Rz surface texture parameter measures the average peak to valley height of the roughness profile. Ra describes the overall surface roughness while excluding extreme points that may be caused by dirt, extreme porosity, etc. The same calculation can be performed on the waviness profile (Wz) and primary profile (Pz).

Rzx, Wzx, Pzx – Maximum Height in Section

The Rzx surface texture parameter is the maximum height of the roughness profile in a section. Rzx helps locate locally bad areas in surface roughness. The same calculation can be performed on the waviness profile (Wzx) or primary profile (Pzx). View more surface texture parameters in our Texture Parameter Video library.
