Week 8 - Challenge 1 - Base Bracket Design

Aim:

To do create a solide base bracket using a given Class A suface from .igs file adto perform draft analysis .

Report:

• the given file contain multi Class A surface . to perform the analysis all the surface get into a single Class A surface using trim commend.
• now the top view gives the perfort look of tooling position. on that a point was created an using point to direction commend a line created as dummy tooling axis.
• Then with the help of intersection opction a surface layout on thr direction of dummy tooling line was created .
• while analysis the layout we can find the critical slop to achive tooling point/axis.
• now using these angled profile a line between those tow line was drawn using byseting line opction. from now on these line act as Tooling Axis.
• now in insert--->Analysis-->Feature Draft Analysis the draft analysis was done.
• in the analysis the draft angle was checked using Analyis using running point opction.
• Now a geomentrical set has insert to create solide object.
• first a spectic three surface picked and get trimmed. now the surface is get offset of 2.5mm from the main class A surface like wise the other rib surface created
• to do so first the surface get untrimmed and extrapolated for 10 mm. and then get trimmed
• like wise the chanfer part and the outer surface get created and trimmed.Now these surface is called as Class B surface.
• Now from the Main Class A surface the outer Boundries are crated to creare complete class c surface.
• These surface is created using sweep -->sweep with draft direction--> draft Draction-->select curve-->Draft angle-->3 degree.
• noq a surface is created to connect Class A and Class B.
• Noe the Class A and Class C surface got Join using Joint Commend. These surface is get trimmed with Class B surface with trim opction.
• now a full of complect surface is formed.
• now again insert the Draft analysis option to check the createed surface to the tooling axis.
• now jump in to Part work bench to close Surface option to create a solide Base Bracket.
• Now the solide component is created.

Result:

Thus the surface analysis is done using grneractive workbench.
