Question

The figure below shows a symbolic representation of the surface texture in a perpendicular lay orientation with indicative values (I through VI) marking the various specifications whose definitions are listed below. P: Maximum Waviness Height (mm); Q: Maximum Roughness Height (mm); R: Minimum Roughness Height (mm); S: Maximum Waviness Width (mm); T: Maximum Roughness Width (mm); U: Roughness Width Cutoff (mm).

Correct answer (A) I-R, II-Q, III-P, IV-S, V-U, VI-T Solution According to the standard for surface texture symbols (ISO 1302), the positions around the check-mark symbol correspond to specific parameters: Position I (top left): Roughness value (R in this context). Position II (inside the check): Production method or additional roughness height (Q). Position III (above horizontal line, left): Sampling length or waviness height (P). Position IV (above horizontal line, right): Lay direction or waviness width (S). Position V (right of the symbol): Machining allowance or roughness width cutoff (U). Position VI (below horizontal line): Other roughness values or roughness width (T). Matching these with the provided list leads to the sequence: I-R, II-Q, III-P, IV-S, V-U, VI-T.
