Week 8 - Challenge 4 - Coin Holder Design

REPORT:

• For the given Coin Holder catpart first we need to make the basic checks i.e. check the continuity of the part ensure that there is no gap between the surfaces we can take the help of surface command for this
• To create the tooling axis create a axis system and form a intersect of Coin Holder Class A Surface with respect to the YZ plane
• Extract the base surface of Coin Holder create a point in centre and create a line normal to the surface and from the point and we would get the Tooling Axis
• For the draft analysis go to Insert-Analysis-Feature Draft Analysis and make sure the view mode is on material
• Inline the compass with the Tooling Axis and lock then click on the Coin Holder Class A Surface we will get the draft analysis for the Coin Holder Class A Surface the minimum draft required is of 3 degrees
• When we click on the Coin Holder Class A Surface it will turn green that means the required draft angle is maintained
• We can change the value of draft angle from the colour scale table and the Class A Surface will change the colour accordingly
• We can also analyse the draft at a particular point on the Class A Surface by moving the mouse cursor on the surfaces
• To generate the Class B surface extract the Class A Surface faces individually untrim them and offset at a distance of 2.5mm
• And finally trim the unnecessary faces and provide fillets we would get the Class B Surface
• To obtain the Class C Surface create boundary for Class A Surface and sweep it till 4mm distance
• To obtain the final solid Coin Holder plastic component trim the needless surfaces and join the class A,B & C surfaces together
• Then use closesurface command to form solid component
• At the end perform the draft analysis on the solid plastic component
• Also publish the Tooling Axis and Class A,B & C surfaces
