Exercises
- The importance of Engineering DrawingExplanation of the scope and objectives of the subject of Engineering Drawing Its importance as a graphic communication -Need for preparing drawing as per standards – SP-46 -1988 -Mention B.I.S – Role of drawing in -engineering education – Link between Engineering drawing and other subjects of study.
- Engineering drawing InstrumentsClassifications: Basic Tools, tools for drawing straight lines, tools for curved lines, tools for measuring distances and special tools like mini drafter & drafting machine – Mentioning of names under each classification and their brief description -Scales: Recommended scales reduced & enlarged -Lines: Types of lines, selection of line thickness – Selection of Pencils -Sheet Sizes: A0, A1, A2, A3, A4, A5, Layout of drawing sheets in respect of A0, A1, A3 sizes, Sizes of the Title block and its contents – Care and maintenance of Drawing Sheet, Drawing plate: Lay out of sheet – as per SP-46-1988 to a suitable scale – Simple Exercises on the use of Drawing Instruments. Importance of Title Block.
- Free hand lettering & numberingImportance of lettering – Types of lettering -Guide Lines for Lettering – Practicing of letters &numbers of given sizes (7mm, 10mm and 14mm) -Advantages of single stroke or simple style of lettering – Use of lettering stencils
- Dimensioning practicePurpose of engineering Drawing, Need of B.I.S code in dimensioning -Shape description of an Engineering object -Definition of Dimensioning size description -Location of features, surface finish, fully dimensioned Drawing -Notations or tools of dimensioning, dimension line extension line, leader line, arrows, symbols, number and notes, rules to be observed in the use of above tools -Placing dimensions: Aligned system and unidirectional system ( SP-46-1988)-Arrangement of dimensions Chain, parallel, combined progressive, and dimensioning by co-ordinate methods-The rules for dimensioning standard, features “Circles (holes) arcs, angles, tapers, chamfers, and dimension of narrow spaces.
- Geometric ConstructionDivision of a line: to divide a straight line into given number of equal parts -Construction of tangent lines: to draw interior and exterior tangents to two circles of given radii and centre distance -Construction of tangent arcs: -i) To draw tangent arc of given radius to touch two lines inclined at given angle (acute, right and obtuse angles)-ii)Tangent arc of given radius touching a circle or an arc and a given line-iii)Tangent arcs of radius R, touching two given circles internally and externally -Construction of polygon: construction of any regular polygon by general method for given side length, inscribing circle radius and describing/superscribing circle radius – Conics: Explanation of Ellipse, Parabola, Hyperbola, as sections of a double cone and a loci of a moving point, Eccentricity of above curves – Their Engg. Applications viz., Projectiles, reflectors, P-V Diagram of a Hyperbolic process – Construction of any conic section of given eccentricity by general method -Construction of ellipse by concentric circles method, Oblong Method and Arcs of circles method -Construction of parabola by rectangle method and Tangent method -Construction of rectangular hyperbola – General Curves: Involute, Cycloid and Helix, explanations as locus of a moving point -their engineering application, viz., Gear tooth profile, screw threads, springs etc. -their construction
- Projection of points, lines and planes & solidsClassification of projections, Observer, Object, Projectors, Projection, Reference Planes, Reference Line, Various angles of projections -Differences between first angle and third angle projections -Projections of points in different quadrants -Projections of straight line -(a)Parallel to both the planes (b)Perpendicular to one of the planes (c)Inclined to one plane and parallel to other planes – Projections of regular planes – (a) Plane parallel to one of the reference planes – (b) Plane perpendicular to HP and inclined to VP and vice versa -Projections of regular solids – (a) Axis perpendicular to one of the planes (b)Axis parallel to VP and inclined to HP and vice versa.
- Auxiliary viewsNeed for drawing auxiliary views -Explanation of the basic principles of drawing an auxiliary views explanation of reference plane and auxiliary plane -Partial auxiliary view.
- Sections of SolidsNeed for drawing sectional views – what is a sectional view – Hatching – Section of regular solids inclined to one plane and parallel to other plane
- Orthographic ProjectionsMeaning of orthographic projection -Using a viewing box and a model – Number of views obtained on the six faces of the box, – Legible sketches of only 3 views for describing object -Concept of front view, top view, and side view sketching these views for a number of engg objects – Explanation of first angle projection. – Positioning of three views in First angle projection – Projection of points as a means of locating the corners of the surfaces of an object – Use of miter line in drawing a third view when other two views are given -Method of representing hidden lines -Selection of minimum number of views to describe an object fully.
- Pictorial DrawingsBrief description of different types of pictorial drawing viz., Isometric, oblique, and Perspective and their use – Isometric drawings: Iso axis, angle between them, meaning of visual distortion in dimensions – Need for an isometric scale, difference between Isometric scale, and ordinary scale difference between Isometric view and Isometric projection – Isometric and non-Isometric lines -Isometric drawing of common features like rectangles, circular – shapes, non-isometric lines – Use of box and offset methods.
- Development of SurfacesNeed for preparing development of surface with reference to sheet metal work-Concept of true length of a line with reference to its orthographic projection when the line is (i) parallel to the plane of projection (ii) inclined to one principal and parallel to the other -Development of simple solids like cubes, prisms, cylinders, cones, pyramid and truncation of these solids-Types of development: Parallel line and radial line development -Procedure of drawing development of funnels, 900 elbow pipes.
