Week 9 - Challenge 1 - Base Bracket Design
INPUT
BASE BRACKET CLASS A SURFACE.
ANS:
TREE STRUCTURE OF GEOMETRIC SETS
STEP 1: First we have to check the connectivity of the Class A Surface.Ensure that there is no gap between the component, using join command.We can visually check it or by clicking boundary command.It has 3 boundaries one outer and two inner circle boundaries.Therefore first check completed.
STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens. Check visaully which is the best possible tooling axis.Check all three axis. Along x it possible but expensive and y is not possible. z is the best possible tooling axis.
Creating a Tooling axis along z:
Therefore the main tooling axis is along z axis.
Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.
Then after opening the draft analysis tool box go for the compass and place the compass alinged to tooling axis and click on the lock symbol after alinging and further click on the surface.
Creating Class B Surface:
First extracting the right side rib using the extract option from Class A surface.Then perform Extrapolate in order to increase the length.Now trim the surfaces to the required surfaces.Then Offset the surface in order to get the required thickness.Similarly, create the left-side rib.Now Similarly get the slanted as well as the flat surface and offset it to the desired value.And now trim in order to get the required surface.Now fillet the surface to the required amount.
Creating Class C Surface:
Class c surface by using extract method . first extract the boundary of the class A surface. Then by using swipe command swipe the extracted boundary with draft direction.
Draft analysis :
Draft angle is mainly provided to the surface in order to ease the ejection of component through the mould . it maily lies between 3 to 5 degrees. Draft analysis is used to validate the draft angle of all surface of class A. draft analysis have 3 indecators mainly green, red and blue . after analysis Class A surface should always show green appereance.
Draft analysis of Class A surfsce:
