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

DOOR HANDLE

TOOLING AXIS CREATION

• find a tooling direction
• select a point on a surface
• make a axis on the point
• make a intersect on the middle plane
• then throught the draft lines make a line between there connecting points
• make a bisecting line from the draft line with the point
• that will be our tooling axis

CLASS A DRAFT ANALYSIS

• do draft analysis wrt the tooling axis so made
• check the draft report

PUBLICATIONS

• Publish class a and tooling axis

CLASS B SURFACE

• extract and untrim every unfilleted face
• extrapolate them to pass each faces
• then trim them accordingly
• offset the final trim
• extract diff fillets and untrim them and measure there fillet values
• add fillets accordingly

CREATE CLASS C SURFACE

• check wheather the class A end positions are perpendicular or parellel
• select each boundaries accordingly
• if the edge is perpendicular to the tooling axis then do sweep with draft direction and with outside draft of 3 deg WRT tooling axis
• if the edge is parellel do sweep with respect to reference surface and with a inward angle of 90 deg
• extrapolated each of them for trim
• then trim those to join as a one surface

JOINING CLASS A WITH C SURFACE

• extrapolated each surface edges to trim
• final trim without any gap

JOIN THE 3 SURFACES TOGETHER

• trim the surface with B surface to get a closed surface

• then close surface in the part body

RIB DESIGN

• add a new sketch wrt the axis system made earlier
• in that draw to straight lines wrt the design rules
• extract the line wrt rib rules
• thicken the surface in both sides on a new body
• union trim that with respect to the main body
• do draft with 0.5 deg on each side
• add fillets of 0.25 mm
• check the root diameter
• the top length
• check each and every parameters according to design rule

SCREW BOSS DESIGN

• then draw two sets of circles of diameter 5.2 and 8.2 (calculated from the design equation of screw boss)
• then pad it on a new body
• trim with main part body
• do draft on inside and outside of the screw boss
• add fillets and check the values according to the given calculations

FINAL DRAFT ANALYSIS

• done draft analysis with respect to tooling axis and values are attached
