Week 9 - Attachment Feature Creation - Challenge 2
The draft angleis given to body inorder to avoid the scratches on the surface due to friction, also it allows for the part to release from the mold easily.
The minimum draft angle is given 0.5 degree and upto 3 degree is accepted.it is given with respect to tooing axis.
Drafting is done on C surface which connects A and B surface.
The Draft Analysis allows the user to easily analyze a part for proper draft angle. A Draft Angle describes the amount of taper for molded or cast parts perpendicular to the parting line.
Initialy we need to make tooling axis. in door side flange is open in one side , so created a line from the base in Y direction which is taked as the tooling axis and changes the thickness , colour and type of line. tooling axis is the direction of motion of core and cavity. in this part, there should be a side core needed to make dog house, thus created a side core tooling axis in X direction. after tooling axis creation need to do draft analysis of class A. open the featured draft analysis then set the colour varient as we required and coincide compass with the tooling axis , then locked it and placed the curson on the class A and analysed the draft is ok or not.
during drawing, Initially we have given the A surface. First step is to draw the tooling axis by finding the most appropriate direction and using the bisection of tooling axes along X and Y direction by intersecting method,if needed. By inersecting the a suface and a plane , we get the line along it. we can give the drat angle on a body if there is large flat surface or on a circular hole if any.Then we have to draw the B surface by seversl steps and tools like
Extract
Untrim
Extrapolate
Trim
Offset
Then we draw a C surface on by selecting the boundary of the A surface and sweaping it.then we join and trim this two with B surface. and get the closed suuface and later fill by close surface.
then changed the surface into solid by using closed surface. then started to creating dog houses. for that created a point on the required surface and made a axis system, from where mad a dog house with the proper ratio of diamension.
