Week 8 - Challenge 1 - Base Bracket Design
BASE BRACKET CREATION
AIM ; To create solid body from a given Class A surface.
TOOLING AXIS
Creation of tooling axis is one of the most important procedure of a plastic product designer. Tooling axis plays a vital role in product design.
PROCEDURES FOR THE TOOLING AXIS CREATION -
- In this project by looking the class A surface i created dummy tooling axis in the z direction , z axis will be the most suitable axis to create the tooling axis for this particular given surface .
- First created a point in the centre of the circle , and a dummy tooling axis is created through that point in z direction.
- Then using that poin as refernce created a yz plane and by using that plane created a intersection curve , after that by using poin to point line sidelines were created
- after by using that sidelines as reference created the tooling axis using bisecting method
- Bisceting were used to get the exact tooling axis by using the side lines, as shown in the fig below
DRAFT ANALYSIS
The most commolnly used or nominal value of the draft angle given to a plastic surface are 3 deg , sometimes 0.5 also were used.The first step of draft analysis is by pulling the compas to the tooling axis created and if the colour of the given surface after draft analysis is green the surface is suitable for next stage of design otherwise further modification is required. By using the point in the draft analysis we can measure the angle of the very complex surfaces. The importance of draft analysis is to reduce damage of plastic product during the manufacturing and easy removal of the mold from the cavity during the injection moulding.
