Week 9 - Project - A pillar Design with Master Section
Class A surface is a Styling surface or aesthetic surface get it from the styling team. we will design the plastic component by using the Class A surface as input Check all the views of the given class A surface that can help us to understand and get more understanding of the component Connectivity of the class A surface and that there is no gap between the component, by using joining command or boundary command we can check
CREATING THE CLASS B SURFACE
Class B surface is to be creating the engineering features and offsetting the surface of class A. Firstly we will extract surfaces by using the extract command from the class A surface. And if there are any patches we have to make it a smooth surface and finally get the complete boundary.
CREATING THE CLASS C SURFACE\
Class C surface is connected the Class A and Class B, For the class C surface, we need to create the entire boundary of the component by using the boundary command And also create the best way for the tooling direction to manufacturing easily in an effective way By using the sweep command we can combine them and trim the surfaces so we can get the completed closed surface body and draft angle given as min 3 degrees Before trimming the most important things join them all After the body has to be closed by using the closed surface in part modeling
FINAL CLOSED BODY
TOOLING DIRECTION & BISECTING
The tooling direction would be at the axis at that direction it is very easy to manufacture and all and all faces and the entire surface are to be covered in that direction without adding any other equipment Bisecting, an articular surface is a tool or not we intersect the surface with the respective plane and get a sketch which consists of two lines, and with the help of bisecting line option, we bisect the line which creates a line at the midpoint of the two lines Likewise, we create a tooling clearing axis for x and y which will be used to create the main tooling axis using the bisecting line option in the line command
DESIGNING OF THE DOG HOUSE
The dog house is an engineering feature used in the plastic trim design. Dog houses are used as supporting features. Sometimes other engineering features like snaps; locators, etc. are mounded on them to increase their strength. The dog house is mostly used in automotive plastic and its main purpose is to help to avoid sink marks and save of wall thickness
There are many design factors considered into the design of a dog house:
Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ) The height of ( B ) should be between 3.0 – 6.0 mm Extract the base of Class A Surface and offset it with a part thickness of 2.5 mm Draw a sketch of the open rectangle and extrude the rectangle at some height of 30 mm Close the upper surface face by offsetting the below-extracted surface and then after trimmed it applying part thickness as 2 mm Give the draft to the inside surface of 0.5 degrees Now to create the C and B sections as shown in the design rules, offset the base surface between 3 to 6 mm.
