Figure 8
The image consists of four line plots, designated as (a) to (d), each depicting the main effects of different factors on surface roughness measures Ra, Rz, RSm, and Rku respectively for S3 in micrometres (µm). Each plot features the x-axis representing parameters including HRC, abrasive type, Mohs hardness, and particle size in micrometres, while the y-axis indicates mean values. Data points are connected by lines for clarity, showing fluctuations in mean values based on the varying categories for abrasive types, which include BC, FBC, G, P, WC, and WS. The plots highlight the structured relationship between the variables, with repeated elements across them, making it easy to compare effects across the different measures.Main effects plots of (a) Ra, (b) Rz, (c) RSm and (d) Rku, considering the effect of HRC hardness of the metallic material, the type of abrasive, the Mohs hardness of the abrasive and abrasive particle size
