Week 9 - Project 1 - Door Trim Lower with Engineering Features

Report for the above challenge is as follows :-

Tooling axis creation.

• At first tooling axis is to defined to perform draft analsys on given A surface.
• A flat surface is identified and extracted from the given A-surface.
• A point is marked on the extracted surface and a line is created normal to the surface.
• Since the line created is normal to the surface, bisecting line is not requred here.
• With the help of the line draft analsys is performed on the given A-surface.

Draft analsys shows green colour on the given A-surface which indicates the surface can be drafted for upto 3 degees.

After Draft analsys, B surface creation is proceeded :-

• At first given A-surface is offseted to 2.5mm as specified.
• Than the patches are identified and extracted which were left after offset.
• Than with the help of boundry, extrapolate and trim command each patches are extrapolated and trimed with the surface. Process is repeated untill all the patches are cleared.
• Than with the help of measuring tool, fillets are measured from the offset and as per measurement edges are given proper fillet to obtain desired B surface.

Creation of C surface is done after B surface.

• Boundry is taken on the given A-surface.
• On the marked boundry with the help of sweep command surface sweep is created with reference to surface and markded angle is 90 degree, length of the sweep is kept 5mm.
• Same operation is carried out on all edges of the A surface and than joined together to obtain C surface.
• After A and C joined together, B surface is extrapolated so that it can be trimed with the joined (A and C) surface.
• After triming the obtained body is than made closed body with the help of close surface command in surface workbench.

Draft analsys is performed on the obtained closed body which shows green colour that indicates the obtained surafce can be drafted upto 3 degress and blue colour indicates that the draft is less than 3 degress.

For Heat stakes and locators.

• Given A surface with marked points is extracted.
• On the extracted surface and marked point plane is defined.
• On the defined plane using positioned sketch two circles of dia 5,, and 7mm are drawn for heat stakes.
• The drawn sketch is padded and drafted for 0.5 degree and edge fillet given of 0.3mm and height 15mm. on the same point support ribs are drawn for the heat stakes and padded for 1mm thickness and given draft for 0.5 degree.
• Now using point to point translate option the heat stakes are translated to all the marked points on the surface and than added to the main body.
• Than again a point is taken on the surface to form 4 way locators. sketch of 10mm x 10mm is drawn and paded to thickness of 1mm and than draft is given for 0.5 degree, chamfer 2mm, height 25mm, edge fillet given 0.25mm.

Draft analsys is taken on the final formed surface and its shows green colour which indicates the surface can be drafted to 3 degrees with all the engineering features.
