Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

1. Title: Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

2. Objective: To design a ‘Sheet Metal part for odd shapes’ using Siemens NX Sheet Metal Application.

3. Introduction: To design a ‘Sheet Metal part for odd shapes’ using Siemens NX Sheet Metal Application.

4. the design methodology and approach is explained in the following documentation.

5. Description:

 1. a solid body is created using the given dimensions.

 2. it is then wrapped with sheet metal using the sheet metal from solid command.

 3. faces are selected with the bending edges as input for this command to work. the bottom surface is not selected as exclosure is supposed to be hollow.

 4. features such as flange is added then on one side of the enclosure.

 5. on the other side, first a single line is made on teh surafce and JOG command is used to extend the sheet metal with an angle with respect to this line then again bent over 90 degrees to follow the original parallelism of the parent sheet.

 6. this whole sheet metal structure is then unbent.

 7. more features such as bead are added. two lines are drawn on the surface of the sheet metal which are then specified as 3mm depth and 3mm radius.

 8. another feature added is the holes. total of 6 holes are added.

 9. then this flat sheet is rebend to get the fianl odd shaped enclosure.

 10. a flat pattern of this sheet is created to display the bend radius, bend angle and bend direction for all the bends used to form this enclosure.

6. conclusion: Designed a ‘Sheet Metal part for odd shapes’ using Siemens NX Sheet Metal Application.
