MT405PC: Machine Drawing and Computer Aided Graphics ME-M Syllabus for B.Tech 2nd Year 2nd Sem R18 Regulation JNTUH

Course objectives:

To familiarize with the standard conventions for different materials and machine parts in working drawings. To make part drawings including sectional views for various machine elements. To prepare assembly drawings given the details of part drawings. To Learn the concept of fluid system and analyzing the applications of fluid systems in power transmission. To prepare CAD 2D and 3D part models using AUTOCAD and Solid works.

Course Outcomes:

• Preparation of engineering and working drawings with dimensions and bill of material during design and development. Developing assembly drawings using part drawings of machine components.
• Conventional representation of materials, common machine elements and parts such as screws, nuts, bolts, keys, gears, webs and ribs.
• Types of sections – selection of section planes and drawing of sections and auxiliary sectional views. Parts not usually sectioned.
• Methods of dimensioning, general rules for sizes and placement of dimensions for holes, centers, curved and tapered features.
• Types of Drawings – working drawings for machine parts. Title boxes, their size, location and details – common abbreviations and their liberal usage.
• Understand the use of hydraulic and pneumatic systems and design of hydraulic and Pneumatic circuits for industrial applications.
• Preparation of 2D Drawings and 3D Basic solid models using CAD.
