A surface finish of 0.4 mm Ra is exactly equivalent to 16 uin CLA. Rt, which is the total height of the profile. There is no mathematical relationship between Ra and Rt.... The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.

the roughness chart. The distance between the peaks and valleys of the sampled line is measured in the y direction. The value is expressed in micrometerr(O m). A section of standard length is sampled from the mean line on the roughness chart. The mean line is laid on a Cartesian coordinate system where in the mean line runs in the direction of the x-axis and magnification is the y-axis. The
