Week 8 - Challenge 4 - Bumper

BUMPER CHALLENGE REPORT

TOOLING AXIS CREATION AND DRAFT ANALYSIS:

• Initially verified the input given with respective all sides and with repective proper boundry too
• then selected the flat surface through which entier boundry can be seen and selected the flat surface and checked with the partial draft analysis
• and created a line through the flat surface with normal to surface method .
• and done the feature draft analysis with respective the tooling axis created earlier .

CLASS B SURFACE CREATION :

• Used the offset method for the b surface creation
• initially off seted the class a surface overall with repect 3 mm down wards
• some of the surface got missed due to compressive issue mainly edges with small fillet radius got missed in 3 areas
• so filled those areas by usid extrapolate ,sweep(with reference to surface ).multi section surface and checked atlast is there any improper surface finish or boundry CLASS C SURFACE CREATION
• TAKING THE INPUTS FROM THE CLASS A SURFACE CREATED C SURFACE BY USIng SWEEP AND MULTI SECTION SURFACE COMMANDS
• in sweep command used with draft dirction option witg 3 degrees as input and direction outside
• and in some surfaces used with reference to surface command with 93and 90 as input direction outde towards b surface
• in order to join both the surface (a b and c ) used intersect command to check both surfaces are proper getting intersect or not and if not extrapolated the b abd c surfaces by using extrapolate command and sweep
• and trimed join od a and c surface with b surface and checked if theres is any extra boundry or not
• 

final draft analysis

checked surface whether there is any boundry is getting created in the close body or not after confirming applied the draft anlysis found in some area due to improper cross section some c surface areas are not getting cleared so those surfaces with respective a surface need some alternations regarding draft and surface creation

these c surface are not getting created so need some aternations on the a surface to correct these errors

and a and c surface will bw created using cavity and b surface and some part of c surface will be cleared in core
