Week 9 - Project - A pillar Design with Master Section

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. The screenshots are attached belows.

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 boundary is taken on the part left after offset and with the help of mutisection command, patch is fixed and than joined with the main surface.
• The body is than extraploated for extra 2mm.

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 97.5 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 B-surface 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.

Dog House creation :-

• After creation of close body, Master section is extracted for the given position of dog house.
• On the extracted line point is marked and plane is defined.
• On the defined plane with the help of positioned sketch dog house sketch is created of dimension, 30x30mm height and width, wall thickness 2.5mm, edge fillet 1.5 mm outside, base coring is between 3 - 6mm. All the measurement are taken from the master section and than applied to the part body. Drafting operation were pre performed on the master section dog-house.

Tooling axis for dog house :-

• Two lines are extracted from the given master section.
• taking the extracted lines, with bisecting method a bisecting line is taken for tooling axis of the Dog-house.
• On the defined tooling axis draft analsys for Dog-house is performed.

Draft analsys for Dog-house as attached in the figure show green colour on outer faces that indicates the faces can be drafted to 1.4 degrees. Inside faces shows blue colour which indicates the inner faces are less than 1.4 degrees.

Draft analsys is taken on the final closed surface and its shows green colour which indicates the surface can be drafted to 3 degrees with all the engineering features. Front and bottom edges shows both green and blue colour which is analysed under running point and found out to draft above 8 degree for which screenshot is shared.
