WebJan 5, 2024 · Jan 20, 2024 #1 Hello Everyone, I need your help regarding the parameters that I need to choose for measuring the surface finish on an inside diameter. The length that the finish needs to be maintained is 12mm and the requirement is Rz5. According to the spec for Rz5 the cut-off length has to be 0.8mm., My question is the evaluation length. WebIn basic terms, a cut-off is a filter and is used as a means of separating or filtering the wavelengths of a component. Cut-offs have a numerical value that when selected will reduce or remove the unwanted wavelengths on the surface. For example, a roughness filter cut-off with a numeric value of 0.8mm will allow wavelengths below 0.8mm to be ...

WebJan 6, 2024 · Surface Finish consists of waviness, lay, and roughness, but it is common for only roughness to be specified on technical drawings. Ra is average roughness, and it under-estimates surface height variations. Rz is mean roughness depth, and it approximates the size of the most severe surface height variations. Ra < Rz in most cases. WebThe sampling length is usually defined as the cut-off length (λc) of the filter used to separate roughness and waviness. For example, using a cut-off length of 0.8 mm and 5 sampling lengths, parameters will be estimated on each segments (Ra1, Ra2, ., Ra5) and the parameter value will be given as the mean of these estimated values.
