Week 8 - Challenge 3 - Coin Holder Design

Coin Holder

Draft Analysis

As from the isometric view the following Fan Surface is analyzed with x,y and z axis.

X axis tooling direction analysis - It can be seen that extra side core is required to clear the part hence the x axis based tooling cannot is not considered.

Y axis tooling direction analysis - It can be seen that all portion of the part is cleared through this tooling direction and hence the y axis is considered for tooling.

Z axis tooling direction analysis - It can be seen that inner portion of the coin holder cannot cleared and may require additional tooling to clear hence the z axis is not considered for tooling.

Further, the bisecting method is not used to create tooling axis along y axis.

Class A Surface draft analysis

TOOLING CLEARING X DIRECTION

A cross section intersection along x direction is taken. Further the edges that are parallel and the slant edge is negligible. Hence no axis is created for tooling axis.

TOOLING CLEARING Z DIRECTION

A cross section intersection along Z direction is taken. Further the edges that are parallel and doesnot intersect with tooling axis.

TOOLING AXIS

The tooling axis is created by extracting the bottom surface and a midpoint is created at the center of the surface. The line command is used and a vertical axis is through the point created along y direction. Therefore the tooling axis is created.
