Week 8 - Challenge 1 - Base Bracket Design

report :

first we will get class A surface as the input from the class A surface we have to create class B surface and class C surface .Before creating the class B surface we have to create the possible tooling axis so that it can be manufactured easily with low cost.the most of the best possible tooling direction is z axis to create a tooling axis in z axis first we have to create a bisecting line in y direction but before creating the bisecting line we have to create the intersection along the y direction to get a bisecting line

after getting the bisecting line on y direction we have to create a dummy geometry along the x direction. after getting the bisecting line of x direction we have to create another bisecting line between the two bisecting lines of x and y direction perspectively and that line will be named as tooling axis.

 the tooling axis

after getting the tooling axis we have check drafting analysis on class A surface so that we can make the component thickken 

drafting analysis method:

go to insert>anlysis>feature draft analysis

after clicking on drafting analysis tool, click on the compass tool and drag it to the tooling axis and lock the compass

after locking the compass cilck the second option on display too bar in draft analysis and then we have to check the drafting angle

the minimum drafting angle should be 3degree.

after completing the drafting analysis we have to create class B surface by extracting each part of the class A surface by ignoring the fillets and then we have to offset each parts separately to the given direction and distance and  untrim the extracted components and then we have to hide the extracted components and then extapolate the untrimmed components to a certain value by using point continuity method so that the component is fully extapolated by all the sides and then we have to use the trim command to trim the the extra components

using the trim command to trim the extra components.

After trimming the extra components we have to make fillets to their value and the thickness of the component for example if the fillet value is 15 and the thickness is 2.5 we have to give the fillet value such asthe value of the fillet +the thickness of the component15+2.5=17.5 for inner surface if the component should be made in reverse direction(oute side of class A ) means we to do the vice versa of it.

After doing all this we have to make a class C surface by creating a boundry on the class a surface which is including the holes and then we have to use the sweep command.

select sweep>profile type>chosose the second type profile>sub type>with draft direction 

and choose the guide curve it is nothing but boundary and select the draft direction(tooling axis)and then give ok to a minimum length but the length should be more than the thickkness of the component so that later we can trim it.

after sweeping the class A surface use the join command to join the class C surface(sweep) with class A and join the both class A and class C surface and un hide the class B surface and use trim command to trim class A nd C (join) with class B surface and we will get the ouput as following

but after doing all this we have got only surface which is hallow inside but we need a solid part so we go to part design and use the close body command to close the surface and make it a solid body.

after finishing all this we have to check the draft analysis for the solid component by selecting compass tool in the direction tool bar and dragging it to the the tooling axis and then locking it there and the using the compass and checking the drafting angles. The drafting angle should be maximum 3 degree and it should not increase more than that after placing the compass we get a red dot in the curser by clicking that red dot in the component the component colour will change and the top face becomes green and the bottom face becomes red.

in which the green colour is saying that the draft is more than 2degree

and the bottom red colour is saying that the draft is less then 0 degree the red colour was not original before it was blue colour but for our reference i have changed it to red colour so that we can find it easily it is has an negative value

after finishing the checking of drafting analysis we have to hide the drafting analysis and then our component is reday for manufacture
