Week 8 - Challenge 3 - Coin Holder Design

TOOLING AXIS

• After analysing the class A surface, due to the presence of the large cavity,it was understood that it woud be better to place the tooling axis with reference to the cavity.
• An axis system was placed in the middle of the cavity and was used to intersect the A surface in 2 mutually perpendicular planes.
• The inclined surfaces were projected in to lines and these lines were bisected to form 2 tooling axis respectively.
• The 2 tooling axes thus formed were further bisected to form the actual tooling axis.

DRAFT ANALYSIS CLASS A SURFACE

• After preparing the tooling axis, the A surface was analysed for draft.
• The compass was moved to align with the tooling axis.
• The color code option was enabled and on clicking the surface, the surfaces having angles greater than 3 were highlighted in green.
• The running point analyser were used to check the draft angle values.

DRAFT ANALYSIS END PRODUCT

• On completion, the end product was analysed in the same manner.
• The compass was moved to align with the tooling axis.
• The color code option was enabled and on clicking the end product, the surfaces having angles greater than 3 were highlighted in green and those having negative angles were highlighted in red.
• The running point analyser was used to know the angle of draft.
