Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
Title: Casing Design Using NX Sheet Metal Application
Objective:
The main objective of this project is to design Casing model using NX Sheet Metal by using some of the commands in the PLM software and plot the 2d view in Drafting module of NX.
Introduction:
Sheet Metal is used in various industrial applications and we can also see it in our day to day life frequently.Even in automobiles,aerospace applications sheet metal is used.In this project we have created and explained the procedure of creating Casing Design in NX using different features.
Design Methodlogy:
Description:
After completion of drawing this Casing Design in Nx we will get familiar with user interface of the software and also we can learn some technicals of sheet metal.
Some of the features used in this are:
a)Sketch:
The sketch is the basis for a model. You can create a sketch on any of the default planes or a created plane.
b)Tab:
Tab in sheetmetal is used as similar to extrude option which will make 2d sketch into 3d model by giving appropriate thickness to it.
c)Normal Cutout:
The extrapart of the sheet metal is cutout using this command wherever it has to be trimmed.
d)Flange:
Flanges are the bent part of the base sheet metal which are also called as Web.By using this command we input the angle of the flange,height and draw a shape of it using sketch.
e)Break Corner:
It is nothing but filleting the sharp edges of the sheet metal.This will give a smooth profile at thhe corners which will improve the aesthetics as well as safety.
f)Screw Hole:
We can provie the mounting holes for the sheet using this command by using the standard library of screw holes available as per our requirement.
g)Dimple:
Dimples are the shapes formed on the sheet by using a puch tool shaped as the shape of the dimple.In this first we should draw a sketch of our required shape and give parameters for the dimple depth and radius.Dimples are added in the sheet metal to reduce weight and to increase the rigidity of the sheet metal.
h)Bead:
Bead is similar to dimple but generally beads are round in shape.It is also added to the sheet metal to improve the stiffness.
