Week 8 - Challenge 1 - Base Bracket Design
BASE BRACKET DESIGN
1. TOOLING AXIS : Tooling axis means the direction in which core and cavity open and close.Tool is nothing burt mold, tooling axis is created to know in which direction the mold open and close, parts drafts are given along this axis.
2. MATERIAL SELECTION FOR BASE BRACKET AND REASON FOR SELECTING THAT PARTICULAR MATERIAL : Thermoset plastic is the material used for the base bracket. The reason for selecting this material is, they will not melt back into a liquid anymore, nor can they be recycled. These properties make thermoset plastics incredibly robust. They are also highly resistant to heat, chemicals and mechanical strength.
3. DRAFT ANALYSIS : Draft analysis is done to check weather the tooling axis and draft angle are correct or not and to find weather the component is manufactured and ejected or not. Draft Analysis is a tool in CATIA which identifies the zones which deviates from the specified values of angles along a defined draft direction using colour codes.
4.CLASS A SURFACE : Asurface is the aesthetic surface created by the class-A engineer. It is the visible aesthetic surface of any automotive component. class A surface is any of a set of freeform surfaces of high efficiency and quality.
5. CLASS B SURFACE : B surface is the offset of the class A surface. Class B surfaces are Engineering Surfaces which are invisible to the eyes or often on the back side of the Class A surfaces. It is mainly the thickness of the component or Class A.
6. CLASS C SURFACE : C surface is joining surface between A and C. Class C surfaces are connectors between Class A and B surfaces. This surface connects both A and B surfaces along the Tooling Axis. It contains the draft as per the design. Its is basically the thickened surface between both A and B surface.
