Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

Title         :   Sheet metal casing  design using Siemens NX

Objective :  Design  of casing  using Siemens NX

 Introduction  :

In sheet metal design casing design it   going to design siemens NX I sheet metal user interface where all the tools design   has used such  as   corner , blend and punch operation .

Sheet metal casing design often  involve bends and flanges .  Use the blend  tool  and flange we easily create the  feature . all the design of sheet metal  casing have  with proper  dimensions include bend angle and  bend radius .

Design methodology

 

<!-- [if gte vml 1]> <![if !mso]>

<![endif]> Create  a sketch with 60mm * 50mm dimension with tab option the  tab feature <![if !mso]>

<!-- [if gte vml 1]> <![if !mso]>

<![endif]> From menu button   preference  option  - sheet metal  -  make all the parameter  set to 1mm <![if !mso]>

<![endif]> Normal cut out option create a sketch with 40 mm*5mm length  on the  base  surface of casing <![if !mso]>

<![endif]> <![if !mso]>

<![endif]> Unbend option we flatten the surface of casing and used bend corner  option to make fillet of 1 mm <![if !mso]>

<![endif]> <![if !mso]>

<![endif]> Create a  sketch  plus symbole on the  base surface  with help of line  command with as reference  line                       <![if !mso]>

<![endif]> <![if !mso]>

<![endif]> Create the flange  with 5mm  length  in  4 side of the casing <![if !mso]>

<![endif]> <![if !mso]>

<![endif]> We used  bend command  to make  a flange in both the side of casing <![if !mso]>

Description

Tab command

Tab  command has used to create a sketch 60mm*50mm  rectangle on the base  surface of the casing  make a thickness of 1mm

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Normal cut

In normal cut option we have  create  a sketch o f40mm*5mm dimension with  the help of normal  cut option we cut the  sketch  section from the  casing base surface .

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Bend command

Bend option has used to bend the flange  which we create the sketch on the base surface of casing  is 10 mm  from  the boundary .

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Flange

Flange command has used in all the four side of the casing   corner  with 5 mm set the parameter inside length with corner relief  bend only option .offset  value is  5mm

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Break corner

Break corner command has use to make a blend the corner all the edged of the   casing with 1 mm  .

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Unbend  command

Unbend command has used to  make a flatten the casing surface .

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Dimple command

Dimple command has used after creating the sketch  on the base surface of the   casing   all the parameter set to be 1mm.

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Bead Command:

Bead command has used after creating  a circle on the surface of casing   with 5 mm dia in     4 side of casing .

Conclusion  :

The sheet metal casing design  has been created in NX software  with consider the all design consideration .
