Week 8 - Challenge 3 - Coin Holder Design

OBJECTIVE

AIM:Developing the coin holder plastic model design from the giving input class A surface by creating class B and C surface.

TOOLING AXIS:Tooling axis is the movement direction of the mould and cavity so it is very important to creat the tooling axis for the plastic product model while design to analiys the draft angle effect for the product for this model the tooling axies is created by suing normal to surface method there are different type to creat tooling axies which is mention below

• normal x,y,z
• point and direction
• normal core axies
• bisecting method

first we have to analys the model and find the suitable surface where the tooling axies can creat then next extract the surface and by using normal to surface option in line creation tool, creat the tooling axis for the model.

once the tooling axis is created we need to do draft analysis for the given class A surface

DRAFT ANALYSIS: It id very important to give draft angle to the plastic product to avoid damage or defective product output from the mould the draft angle using in industries are 3 degree. Drag the compus to the tooling axisand kept in center and then click on the compus icon on draft analysis dialogue box the compus will active again need to alingn along with tooling axis

once the compus alingned with tooling axies click on the model to do the draft analysis the model is convert into green colour then its indicate model is perfect for modeling and if it is showing red in color then click on the draft analysis dialogue box in reverse icon and the model willget turn into green color after click on reverse icon still the model in red color the dont proceed futher snd revert back to class A surface engineer.
