Week 8 - Challenge 4 - Bumper
Aim:
This project aims to create a switch bezel plastic component using the given class A surface following the OEM standard. and perform the draft analysis.
Objective:
- Ensure Proper Tree Structure.
- Geometrical sets should have a proper name based on the sketches present inside them.
- All the sketches should be created under the Geometrical set.
- Use the Close Surface feature to make a solid body from the surface.
- To publish the Tooling Axis, Class A, B, and C surface.
Tooling Axis:
The Dummy tooling axis is created to creat the main tooling axis.Take the intersection of the bracket body and make the lines in the deficult area in the bracket.Then Bisect the lines to create the tooling axis.
CLASS-A SURFACE:
The class-A surface is used in the automotive design industry. it describes the final production surface data for the aesthetic parts.
CLASS-B SURFACE:
The class-B surface is the second surface that has a certain thickness from the class-A surface. this surface contains engineering aspects of a model. These must be smooth and "error-free" as well but are not held to the standards that class A surfaces are.
CLASS-C SURFACE:
The Class C finish allows more imperfections than Class A or B. Class C is often specified for interior surfaces not readily visible, surfaces that will be covered by another part when assembled, or surfaces. Join class-A and class-C surfaces. Make sure that there is no unnecessary boundary present, if there is then increase the merging distance to not more than 0.003mm. and even after there is some unwanted boundary, extrapolate class-A by a small distance and trim it with class-c instead of joining them.
Draft Analysis:
The Draft analysis is performed based on colour ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values. Here I am taking the draft angle 0 to 3 degree. Value obtained less than 3 will be highlighted in red, These regions Drafting is not possible .Hence Tooling axis should be changed or additional process is to done to produce the part.The drafting are been performed in both the core and cavity side of Class A Surface. The Green colour Implies the draft angle are in the positive region. if The draft angle are been inverted the colour of the surface are imled as Blue colour.
3 DIMENSION PART AND ORIENTATIONS:
- Front View
- Side View
- Top View
- Isometric View
Conclusion:
- The Base Bracket Plastic Part Component using the Class 'A' surface are Created.
- The Tooling axis for a class 'A' Surface, which meeting the requirement of the draft angle are analysed and perfrmed.
- The solid model from the surface are created by using the Closed Surface Feature.
- The detailed report which explains the Draft analysis and Tooling Axis cration are explained.
- The 3D part Model with various orientations are attached.
