Course Objectives

To equip students with fundamental knowledge of Computer-Aided Design (CAD) tools and techniques for modeling, analysis, and drafting of agricultural machinery and farm structures.

CAD Interface, 2D Drafting and Dimensioning a) Preparation of 2D drawings of agricultural components (shaft, bracket, flange) b) Dimensioning and annotation as per BIS standards
3D Modeling and Parametric Design a) Modeling of components such as plough share, seed tube, sprocket, and pulley b) Parametric modeling of cultivator tine with design modifications
Assembly Modeling of Farm Machinery a) Assembly of seed drill unit (hopper, seed tube, frame, metering device) b) Application of constraints and interference checking
Motion Simulation of Mechanisms a) Simulation of slider–crank mechanism b) Analysis of displacement, velocity, and motion characteristics
Sheet Metal and Surface Modeling a) Modeling of grain storage bin/hopper with flat pattern development b) Surface modeling of tractor hood or curved guard
Finite Element Analysis and Tolerance Study a) Static stress analysis of cultivator shank or plough beam b) Clearance, fit, and tolerance analysis in assemblies

Design and model an agricultural machine component or system (e.g., seed drill unit, cultivator, or hopper) using CAD software, including assembly and basic FEA.
Perform motion simulation of a selected mechanism (e.g., slider–crank or gear system) and analyze its kinematic performance with interpretation of results.
Prepare a report on a real-world agricultural machinery system focusing on design, materials, manufacturing considerations, and scope for improvement using modern tools.

CO1: Develop 2D drafting and 3D part models of agricultural components using CAD tools.
CO2: Create assemblies and perform basic motion/simulation analysis for agricultural engineering systems.
