AFAB 110 FINAL STUDY GUIDE QUESTIONS AND ANSWERS 100% CORRECT.

Are you taking AFAB 110 (Print Reading / Engineering Drawing) and preparing for the final exam? This comprehensive study guide contains 100% correct questions and answers covering every topic you'll encounter. From assembly drawings, part numbers, and revision history blocks to geometric dimensioning and tolerancing (GD&T), surface texture symbols, thread classifications, section views, auxiliary views, and orthographic projection – this resource is your all-in-one exam preparation tool. What's Inside – Complete Final Exam Domain Coverage: Category Key Concepts & Questions Covered Print Reading Fundamentals Part numbers (each part has a part number – TRUE), casting drawings (multiple variations possible – TRUE), revision history block (effective date column, determines if print is up-to-date), application block (provides larger assembly context), drawing deviation (temporary revision authorizing deviation from print), ECO (Engineering Change Order) Assembly & Detail Drawings Assembly drawings (hidden lines critical for assembly explanation), inseparable assembly drawing (two or more parts assembled as one), welding drawing (appears as assembly drawing), pattern development drawing (dimensions for flat stock before forming), controlled drawing (engineering requirements for purchased parts), mono detailed drawing (one detailed drawing of one part) Basic Parts Lists Unit weight (NOT common on basic parts lists), finish (NOT typically included on basic parts lists), balloons (neatly arranged on drawing to identify parts) Geometric Dimensioning & Tolerancing (GD&T) Concentricity (discontinued geometric control), runout (geometric tolerance measured on datum axis with dial indicator), circularity (NOT an orientation control – orientation includes parallelism, perpendicularity, angularity), basic position (theoretically exact location of feature axis/median plane), feature control frame (surface texture symbol NOT found on it), continuous feature symbol (indicates interrupted surfaces treated as one feature – TRUE), maximum material condition (size limit when most material is present), datum (letter in box attached to views) Surface Texture Flaw (unintentional interruption of surface), italic "f" (indicated surface texture before current symbol), 7 lay symbols ("I" is NOT one of them), surface texture symbol placement (centerline of cylinder is NOT a valid placement choice) Tolerancing & Fits Limits (extreme maximum/minimum dimensions allowed – TRUE), bilateral tolerance (example: +.005"), single limit tolerance (incorporates min or max note), RC3 class fit for 1" hole (basic hole = 1 inch), clearance limits calculation (hole 1.500-1.508" with shaft 1.475-1.485" = 0.015"-0.033" clearance), dual dimensioning (alternate part in brackets following primary value), coordinate dimensioning (most useful for CNC machining), not-to-scale method (heavy line drawn below revised dimension value) Threads & Fasteners Triple thread lead (FALSE), thread classes (1A, 2A, 3A are for EXTERNAL threads – internal threads are 1B, 2B, 3B – so statement FALSE), metric threads (appear identical to inch threads on a print – TRUE), Unified thread (minor diameter), UNS (Unified special – non-standard form), thread class 1A or 1 (loses class), rectangle (NOT a thread form), lead (how far thread advances when part turns), pitch (distance from one point on thread to same point on next thread), NPT (National Pipe Thread), NPS (straight pipe thread designation), regular (standard plumbing pipe thread), "M" (metric designation) Section Views Offset section (essential internal details not on one flat plane), aligned section (cylindrical objects with odd number of features), full section view (cutting plane passes entirely through object), half section view (only one arrowhead on cutting plane line), revolved section, removed section, broken-out section Auxiliary & Orthographic Projection Any view projected from front view shows depth (TRUE), auxiliary view projected from right side (width auxiliary view), auxiliary view common reason (show true size/shape of inclined surface), dihedral angle (angle between two surfaces – TRUE), orthographic projection (parallel lines project 3D object to 2D projection plane), inclined surface (perpendicular to one projection plane, inclined to other two), three principal projection planes (vertical is NOT one – correct: frontal, horizontal, profile), polygon (closed shape of straight lines), spline (defines irregular/freeform objects), perpendicular elements (form right angle to each other), chord (line segment connecting two points on circle not through center), tangency (shared point where line touches circle at one point), primitives (basic forms in CAD to create complex models) Lines & Lettering Hidden line (pattern of thin short dashes spaced closely together), section line (lines on surfaces assumed to be cut), cutting-plane line (identified by arrowheads), center line (line going down middle of assembly), lettering (text on drawing), uppercase lettering required unless lowercase specifically required (TRUE), engineering drawings by hand use gothic double stroke (FALSE – single stroke), CAD output devices (FALSE about vector printing limitations) Sheet Sizes & Formats Engineering sheet sizes are multiples of 8½" x 11" (A-size), zones (aid in locating details on revision notes outside border), standards for sheet sizes/title blocks/lists NOT covered in one ASME standard (FALSE – multiple standards), revision history block (important to read at early stage of examining print) Digital & Historical Concepts Raster image (composed of tiny pixels), diazo (1940s dry process using organic compound-coated paper), blueprints (term meaning "plan of action or detailed procedure"), drafting (general term for creating drawings of objects), vellum, visualization (spatial training increases print reader ability) Assembly Instructions Stamp block (marked on bottom of back cap prior to assembly), screws tightened (in cross front/cross pattern) Key Questions & Answers You'll Master: Question Correct Answer Each part of assembly has a part number?
