Week 8 - Challenge 6 - Core & Cavity Design

    UNDERBODY COATING   Underbody Coating is a sprayable coating, which protects the under surface of the vehicle from corrosion. Underbody coating provides long term protection from corrosion to car's underbody. It also protects parts like internal body panels, frame rails and other inner cavities that are not physically…

Benchmarking   AIM:           To prepare a report explaning what is benchmarking,compare atleast 4 CARS and Provide a proper conclusion for the report ,suggesting a suitable vehicle among the comparison made. What is bench marking?               …

Final project   Door Trim Panel   Aim : To create a CAD model of a  side door trim panel from given class A surface .  Objective:  a) Creation of side door trim panle from given class A surface . Apply thickness to it and use attachment features .  b) Creation of flanges and heat stakes from given master sections . c)…

Project 1 - Door Trim Lower with Engineering Features     TOOLING AXIS: To create the tooling axis, I extracted a surface from class A and created a point in the middle of the surface by using the point command and created a line at that point through the x-axis. Now, I performed a draft analysis check from that…

  Attachment Feature Creation - Challenge 2   Tooling Axis:     The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling…

Attachment Feature Creation (Ribs & Screw Boss)         Tooling Axis creation: It is defined as the direction in which the mould/core and cavity open. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected. By analysing the component the most…

Core & Cavity Design      Tooling axis creation: The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the…

Challenge 4 - Bumper     Tooling Direction : The Tooling Direction is basically the direction that the mold pulls apart. The ejection of the part from mold depends on the draft. A zero draft can result in difficult or no ejection due to shrinkage. It is recommended to add a minimum of 0.5 to 1 degree of…

   Coin Holder Design   TOOLING AXIS CREATION: Generally tooling axis is created using bisecting line method. But in the components where it has a bin, then the tooling axis is considered as a line normal to the base surface of bin. Same is done with this component. A line normal to base surface is created…

  Challenge 2 - Switch Bezel Design    Creation of Tooling direction Considering the Ejection from the cavity of the mould after manufacturing the interior trim (switch bezel) must have the nominal 3-degree draft angle. Hence the tooling direction is created by considering the above factor and bisecting…

 Base Bracket Design     DRAFT ANALYSIS: To perform draft analysis, click on Insert >>Analysis >> Feature Draft Analysis Once the draft analysis toolbar is opened, go to the display block and select the 'Analysis under the running point' command to check the angle for different sides (ribs and inclined plane angles) on…

Aim: Creation of Rankine cycle simulator from given input and reading the data from standard thermodynamic library of steam table. Objective: To create a Rankine Cycle simulator in MATLAB. To calculate the state point using function XSteam. To plot the T-S and H-S curve for given input in Rankine Cycle. To get output in…

     Aim:  To write a code in MATLAB to parse the NASA thermodynamic data file and calculate thermodynamic properties of various gas species. Objectives: Write a function that extracts the 14 co-efficient and calculates the enthalpy, entropy and specific heats for all the species in the data file. You…

Aim: To write the code to calculate the global maxima of the stalagmite function and to explain the syntax for genetic algoritham(ga) in MATLAB. Objectives: To write a code in MATLAB to optimize the stalagmite function and find global maxima of the function. To explain the concept of genetic algoritham and the syntax for…
