Rough machining symbol

WebMar 23, 2024 · The basic symbol consists of two legs of unequal length inclined at approximately 60° to the line representing the considered surface. The symbol must be represented by a thin line. The value of roughness is added to the symbols. 1. Roughness ‘a’ obtained by any production process. 2. Roughness ‘a’ obtained by machining. 3. WebMar 17, 2024 · The surface roughness can be smoothed down to a lower Ra with the inclusion of a finishing cutting pass. However, this can increase the price, add extra machining steps, and create a longer production time. Get It Made’s precision machining has surface finishing standards of 3.2μm Ra and 1.6 μm Ra for as-machined parts. ‍.
