Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
Title: Advanced sheet metal design using SIEMENS NX CAD - CASING DESIGN.
OBJECTIVE: To design a CASING DESIGN in Siemens NX Cad with the sheet metal commands.
INTRODUCTION:
SHEET METAL:
Sheet metal is a metal formed by various processes into thin,flat pieces.A metal sheet whose thickness is 6mm is called sheet metal and various processes are carried out on these sheet metal like Blanking,punching or piercing,coining etc.
Usually sheet metal are available in the form of flat sheet plates these flat sheets will undergo different processes based upon the requirement.
NX CAD:
Here in this course we are using SIEMENS NX by which we are going to model some sheet metal parts.
NX CAD has its own advantage over many other CAD softwares in the market,because it is capable of converting the non parametric body into parametric body,can produce sheet metal part from the solid body.
COMMANDS USED:
1.Tab
It used to create a base feature from a sketch extruding along a axis and giving thickness.
2.Flange.
It is used to create an extended feature from the tab feature at an angle and bend radius.
3.Closed corner.
The closed corner command is used to merge the adjacent bends by specifying the Gap.
4.Break corner
The break corner is used to give fillet or chamfers at the sharp ends of sheet metal
5.Unbend
The sheet metal can be made flat by giving the fixed face and specifying the bends.
6.Rebend
The rebend works opposite to the Unbend which is used to bring the original shape of sheet metal.
7.Mirror Body/Feature.
The mirror body/feature is used to mirror the features or body with respect to the plane.
8.Normal Cutout
It works similarly to the extruded cut.
9.Unite
It joins the two bodies along a plane.
10.Datum plane
It creates a plane along an xy,yz,zx at an offset distance.
11.Bead.
It lifts the part of the sheet metal with a given sketch.
12.Dimple.
The Dimple is used to uplift an area and we can specify the direction that simulates a stamping tool.
13.Hem Flange.
It modifies the edges of the sheet metal or folds the edges.Its purpose is for safe handling
14.Flat Pattern
It creates a flat pattern from the formed sheet metal part.
