Week 4 Challenge
Tooling direction- The Tooling Direction is basically the direction that the mold pulls apart. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dyeline or the Tooling Direction.
Approach to Create Tooling Axis - Take a Point on the surface
Create an Axis System:
Create a Line using Point and Direction method.:
Draft Analysis of Lens Class A surface:
Parting line-
A parting line, in industrial casting of molds, is the border line in which draft angles change direction. One can check the parting line in the mould or product which divides the two half, i.e; the core and the cavity of a molded part. It is sometimes a starting point for the mold parting surface.
Approach to Create B surface
Take an offset of B-surface with 4mm offset value.
Check surface quality and to repair, Extract the boundry and surface:
B surface Join:
Approach to Create C Surface
- Sweep the boundry of Class A surface to create Class C surface
Join of A, B and C surface:
Closed Body of lens:
Draft Analysis of Lens Class A surface:
Closed Body of lens:
Approach to Create Parting Line
- To create the parting line, extract the boundry of thickened body as shown in below image:
6. Once that is done create the welding channel. In order to create the channel we need to have a profile we will create that profile either by offsetting the edge of Class A or by creating sketch and control the profile by giving the distance from the projection and the angle between the horizontal and vertical directions. Once that is done sweep these lines in the tooling direction, trim and join these surfaces together. Then try to control the swept surfaces by adjusting the angle and distances in the sketches. For again modifying the curves on surface use spline and split commands to control the profile
- After that thicken the surface with 1mm to both sides.
- The final result:
