Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

DRAFT ANALYSIS 

DETAILED REPORT 

STEP 1:  CONNECTIVITY OF CLASS-A SURFACE

• First check the connectivity of the given surface or component
• This is done by creating boundaries or by using Join command
• Ensure that there is no gap between surface connection
• From this image we can see the boundary inside the surface, it indicates there is a gap.
• To solve this gap, use join option to merging the gap (use merging value as 0.003)

STEP 2: TOOLING AXIS CREATION

• First visually analyse the possible direction of Tooling direction.
• Create dummy tooling axis for possible dolling direction.
• Using the Intersection command create intersection line for all X,Y,Z axis direction.

Inter section of X direction:

• If we have a surface with one sided wall, then create a opposite wall with own.
• Make angle constraint for this line with wall.
• Bisecting these X,Y directions tooling axis, the main tooling axis will create, Where the two lines and one point will be selected as inputs

STEP 3 : THICKEN THE CLASS A SURFACE

• Given class a surface thicken 1.5 mm to get the  required part body through the thicken surface comment in part work bench.

STEP 4: DRAFT ANALYSIS

• Draft analysis is done after determine the tooling axis.
• Ensure weather all the surface angles are more than 3 degrees along with tooling axis direction.
• There are some colour codes are used to easily determine the angle value
• If the whole angle is more than 3 degrees, then surface colour turned into Green for one type scale and for another scale it has 5 colour variation.
• Here our surface area has more than 3 degrees.
• Below 0° angle indicated by red in colour, these are has negative angles.

STEP 5: RIBS CREATION

• New geomentry set created & name it ribs.
• line was drawn for making the rip on B surface through the sketch work bench.
• The line was thicken 0.75mm &  height 7.5mm drawn under the rip construction rule.
• Edge radius 0.25mm given.
• And the rip was drafted 0.5deg with respect to tooling axis.
• The completed rip body again drawn for another rip with the distance of above the 2time of thickness of the handle body.

STEP 6: SCREW BOSS CREATION

• New geomentry set created & name it screw boss.
• Circle was drawn for making the screw boss on B surface through the sketch work bench.
• The circle was multipad 0.75mm thickness screw hole wall,2.5mm screw hole &  height 4.5mm drawn under the screw boss construction rule.
• Edge radius 0.25mm given.
• And the screw boss was drafted 0.5deg with respect to tooling axis.
• The completed screw boss body again drawn for another scre boss body with the distance of above the 2time of thickness of the handle body.
