Roughness Ra Ry Rz Rq. Rq square roughness Rq is the root mean square average of the roughness profile ordinates. RMS Root Mean Square in micro-inches. RC PC-RC GAUSS and D-P. The PCE-RT 1200 roughness tester has an internal memory.
Root mean square deviation Rq Pq Wq Root mean square deviation indicates the root mean square along the sampling length. PCE-RT 1200 is a portable roughness tester used in many different material surface testing applications. Four wave filtering methods. For the roughness profile Rq is referred to as the root-mean-square roughness while Wq is referred to as root-mean-square waviness for the waviness profile. Rq square roughness Rq is the root mean square average of the roughness profile ordinates. Roughness Tester Ra Rz Rq Rt Parameters 3.

KEYENCEs Introduction to Roughness website introduces parameters and case studies related to such surface measurements. Ra is also known as Arithmetic Average AA or Center Line Average CLA. Rq square roughness Rq is the root mean square average of the roughness profile ordinates. Ra M L Rq Roughness Average Ra is the arithmetic average of the absolute values of the profile heights over the evaluation length. Ry - maximum height of the profile. Rt- Rt Total height of the roughness profile.
