Understanding surface finish symbols is vital in ensuring the success of any component outlined within an engineering drawing. The measure of the total space irregularities on the surface metal is known as Surface Roughness. As you know various acronyms are used in machining surface finish symbols including Ra Rsk Rq Rku Rz RMS etc.

The indication of surface roughness values in the surface finish symbols are shown the figure A. The goal of the machinist is to achieve surface finishes on parts that are as good as those required by the designer but not better as that results in the cheapest to manufacture parts. When you search for machining surface finish symbols on your favorite browser you would notice a range of abbreviations.

Post-processing a machined part is easier when you understand the surface finish requirement and specifications needed. An engineering component may be cast forged drawn welded or. Surface Roughness Chart Symbols and Abbreviations.
