Computer-Aided Engineering Drawing (CAED) Lab is utilized by undergraduate students for software-aided drafting of 2D drawings. CAED is a technique where engineering drawings are produced with computer assistance, serving as a graphical means of representing a drawing or design.
Engineering drawing is the global graphic language used by engineers and technologists. It involves the graphic representation of physical objects and their relationships, conveyed through drawings using straight and curved lines to denote shape, size, and specifications. Understanding the theory of projection, dimensioning, and conventions related to working drawings is crucial for professional efficiency.
CAED involves preparing drawings of objects on a computer screen, supporting various types of drawings across engineering and science fields. Mechanical or aeronautical engineering focuses on machine component drawings and layouts, civil engineering involves building plans and layouts, and electrical engineering deals with power distribution system layouts. In all engineering fields, computers are utilized for drawing and drafting, with CAED offering enhanced graphics capabilities allowing designers to conceptualize ideas, modify designs easily, perform animations, make design calculations, and use colors, fonts, and other aesthetic features.

Introduction to Modelling and Design for Manufacturing Laboratory is used by UG students for software aided drafting of machine parts and assembly drawings. This involves study of conventions in drawings that are widely adopted in engineering practice.
Introduction to Modelling and Design for Manufacturing is representation of a machine component or machine by lines according to certain set rules. A machine drawing generally gives all the external and internal details of the machine component from which it can be manufactured. Machine part is presented through a number of orthographic views, so that the size and shape of the component is fully understood. Part drawings and Assembly drawings belong to machine drawing. Part drawing is a detailed drawing of a component to facilitate its manufacture. A drawing that shows the various parts of a machine in their correct working locations is an assembly drawing.
The machining symbols, tolerances, bill of material, etc. are specified on the drawing. GD&T, short for Geometric Dimensioning and Tolerancing is used to define the nominal geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features. GD&T uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation.

Introduction to python Laboratory is used by UG Students. Python is an interpreter, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.
Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn’t catch the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python’s introspective power. On the other hand, often the quickest way to debug a program is to add a few print statements to the source: the fast edit-test-debug cycle makes this simple approach very effective.
The Lab is well equipped with 20 number of high-performance computers. Software packages such as having IDLE (short for Integrated Development and Learning Environment) is an integrated development environment for Python, which has been bundled with the default implementation of the language campus-wide it is free license available from python website, and the same has been installed in the system.

Lathe: Lathe machines are used widely in all mechanical industries and workshops to carry out various operations on the mechanical parts. Turning, step turning, Knurling, thread cutting, center drilling, and cutting are very common operations performed on the mechanical parts. The main function of Lathe machine is to remove excess material in the form of chips by rotating the work piece against a stationary cutting tool. This is accomplished by holding the work securely and rigidly on the machine and then turning it against cutting tool which will remove metal from the work. To cut the material properly the tool should be harder than the material of the work piece, should be rigidly held on the machine and should be fed or progress in a definite way relative to the work.
Following operations can be performed by using lathe machine for fabrication purpose i.e Turning, facing, grooving, parting, threading, drilling, taper turning, boring, knurling, and tapping.
Milling: A milling machine is a machine tool that removes metal as the work is fed against a rotating multipoint cutter. The milling cutter rotates at high speed and it removes metal at a very fast rate with the help of multiple cutting edges. One or more number of cutters can be mounted simultaneously on the arbor of the milling machine. This is the reason that a milling machine finds a wide application in production work. Milling machine is used for machining flat surfaces, contoured surfaces, surfaces of revolution, external and internal threads, and helical surfaces of various cross-sections.
Following operations can be performed by using Milling machine for fabrication purpose i.e
Plain Milling Operation, Face Milling Operation, Side Milling Operation, Straddle Milling Operation, Angular Milling Operation, Gang Milling Operation, Form Milling Operation and Gear Milling
Drilling: The drilling process is an important process in industry because it is used to drill holes in metal, wood, and other materials. The drilling machine uses a drilling tool with a cutting edge at its tip. The cutting tool is fixed in the drilling machine through the taper of the chuck (sleeve), and rotates at a constant speed and is fed into the work piece.
Following operations can be performed by using Drilling machine for fabrication purpose. i.e. Drilling, reaming, lapping, boring, counter-boring, counter-sinking, Spot facing, and tapping
Shaper: A single point cutting tool will be used in shaper machine tools. During the forward stroke of the tool, job will be machined and during the backward stroke of the tool, the tool will be idling. To achieve this, the cutting tools are mounted over an arrangement called clapper box. The mechanism used in Shaper Machine is Whitworth Quick Return Mechanism.
Following operations can be performed by using shaper machine for fabrication purpose i.e. Machining horizontal surface, Vertical surfaces, Angular surfaces, Cutting slots, grooves, and keyways.
