Given A surface Given A surface is analysed for any surface irregularities by Boundry command Creation of Tooling axis : Opening Direction of moulding machine is called tooling direction or tooling axis. Tooling direction is known as primary direction.…

Aim : To create a solid Coin holder component using Surface Modeling with given A surface and perform draft analysis on both. Given A surface Tooling axis : As our A surface contains walls which are at 90* with the bottom so we can directly create a tooling axis on the base which is perpendicular to the base. B surface…

Aim : To Create Class B and Class C Surface with the tooling axis of a base bracket. Given A surface Tooling Axis Extraction Ribs  B Surface C surface Final Joining Geometrical Set Draft analysis Solid part  

Aim : To Create B Surface & C surface from the Given A surface. Given A surface Tooling Direction Extracted Surface B Surface C Surface Joining All the surfaces Together Draft Analysis Geometrical set Solid Part

Aim : To design the back door by using the reference surface. Introduction :             The backdoor of a car is the rearmost part of the vehicle which gives access to the trunk space of the vehicle. The rear door also supports the reinforcements and added weights of the wiper motor, Gas…

Roof Design OBJECTIVE- To create an assembly by developing the essential flanges for the outer roof and creating reinforcements. Provide appropriate dimensions and check for draft analysis. To do curvature study on the roof. DESING CONSIDERATION:- Visibility Criteria Head Clearance Curvature Study Hear Distortion &…

Fender : Fender is the american english term fro the part of an automobile, motorcycle or other vehicle body that frames a wheel well(the fender underside). its primary purpose is to prevent sand,mud,rocks,liquids, and other road spray from being thrown into the air by rotating tyre. it also plays important role in preventiing…

Aim : To obtain the section modulus of the designed car hood & further obtain further improvized Section and compare section modulus of both the hood. Theory : Section modulus is a geometric property or a value given for cross-section used in the design of flexural members. There are two types of section modulus Elastic…

Aim : To design the hood of a car provided with outer panel and master section.  A car hood or bonnet is the hinged cover that rests over the engine of a front-engine vehicle. its purpose is to provide access to the engine for repair and maintenance. Components of hood : hood consists of several parts but as per the…

Wheel Arch:  wheel arch is the semi-circular part positioned above the wheel of a vehicle. while designing arch it should be in mind that wheel should be inside the fender. if not it may causes harm to pedesterians & it may damage car parts also. Regulation Of Wheel Arch: the regulations are decided with respect…

What is Underbody coating? Underbody coating is usually a dense cladding applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the vehicle is just out of the dealership & is clean. Need of under body coating? In indian road conditions, a cars under body is prone to corrosion.underbody…
