Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
THE CREATION AND DRAFT ANALYSIS OF DOOR TRIM WITH ATTACHMENT FEATURES (DOG HOUSE):
TOOLING AXIS:
- The direction of open and close operations in Molding Machines, basically the Direction of the Mold pulls apart.
- The Mold is built in two seperate pieces. so, you have a Cavity and Core sides.The Core pulls apart from the Cavity is the Tooling direction.
THE CREATION OF TOOLING AXIS:
MAIN TOOLING AXIS
- First Find out the possible directionn of Drafting, in this component select a complete flat surface, The axis is created from that surface (reference).
- Extract the selected surface.
- Create a point in the middle of the Extracted surface .
- Finally create A line with the help of point.
SIDE CORE AXIS
- Side core axis is particularly made for Attachment Feature's (dog house) inner side draft analysis. because It's not feasible for Main axis tooling direction machining.so, Side Core Machining is need for Attachment Features.
- First Find out the possible directionn of Drafting, in this component select a surface, The axis is created from that surface (reference).
- Extract the selected surface.
- Create a point in the middle of the Extracted surface and Create a Axis system for Direction reference.
- Finally create A line with the help of point.
THE DRAFT ANALYSIS TECHNIQUE:
- The draft analysis technique is used to analyse whether our part model created in CAD is manufacturable based on the draft condition applied. Here the part should get easily removed from the panel dies (in case of Sheet metal part) or Mold (in case of plastic).
- No parts can be ejected from the tool if it is having a straight 90-degree profile from its base surface. A small draft angle is provided to each and every area of the component in order to get easy removal of the component from the tool.
- Here we are providing a direction in which components should eject in order to get easy removal of components from the tool. In other words, it also lets us know whether the model is having a draft angle and how much is the draft angle from the tool direction.
DRAFT ANALYSIS OF PLASTIC COMPONENTS:
- The ideal draft angle for the plastic components is 3 degrees. This may vary according to the functional requirement. Apart from the draft angle consideration, the remaining procedures for the draft analysis are similar to the above-mentioned steps. The draft angle provided for the plastic features is 0.5 degrees. This may also get varied accordingly.
THE DRAFT ANALYSIS OF THE CLASS-A SURFACE:
- First Enable The Class A Surface for Draft Analysis. then, select the Material Mode on View Mode Customization.
- Insert a Draft Analysis then, click a Compass and drag into the main tooling axis then fix it in the axis with using lock.
- enable the draft angle colour code dialog box for class A surface
- In this case some CLASS A surface areas are not clear the Draft Analysis, I also tried various refences (axis method, bisecting method tooling axis) to clear the Draft Analysis. It's not clearing the Draft.
- so this is the surface need a rework on it by CLASS A surface Designer.
DOG HOUSE CREATION:
DRAFT ANALYSIS (SIDE CORE AXIS-2.9deg-Inner side):
DOG HOUSE-1
DOG HOUSE-2
DRAFT ANLAYSIS (MAIN TOOLING AXIS-1.49deg-Outer side):
DOG HOUSE-1
DOG HOUSE-2
* Minnimum Draft Angle of Dog House is 1.5 deg.
THE DRAFT ANALYSIS OF THE FINAL PLASTIC COMPONENT:
- First Enable The Final Solid DOOR TRIM WITH ATTACHMENT FEATURE (DOG HOUSE) for Draft Analysis. then, select the Material Mode on View Mode Customization.
- Insert a Draft Analysis then, click a Compass and drag into the main tooling axis then fix it in the axis using lock.
- enable the draft angle colour code dialog box for Door Trim.
