Week 8 - Challenge 6 - Core & Cavity Design
TOOLING AXIS CREATION
From the class A surface, we can see flat surfaces facing along the z-axis.
For creating tool clearing y direction, create a new axis system at centre point of flat surface. Then create a sketch in yz plane of new axis system and intersect the class A surface with YZ- plane. Then we got an intersecting line. Choose the line which consider for making tooling axis from intersect lines and create y directional tooling axis by using bisecting line option.
For creating tool clearing x direction, create sketch in yx plane of new axis system and intersect the class A surface with XZ plane. Then we got an intersecting line. Choose the line which consider for making tooling axis from intersect lines. here we can see that only one slope line. Then we create X directional tooling axis by making angle with the slope line and angle must be suitable for making the required draft. Here i used angle as 6 degrees to make the draft perfect.
For creating the tooling axis, create a bisecting line using created Y tooling axis and X tooling axis by bisecting line option.
DRAFT ANALYSIS
The draft analysis of the class A surface ensures that the class A surface is possess a proper draft angle based on the tooling axis.
Draft is providing angles or tapers on product features such as walls, ribs, posts, and bosses that lie parallel to the direction of release from the mould easing part ejection.
Using the draft analysis tool, we can identify the zones using colour codes and high lights the areas which deviate from the specified values along a defined draft direction.
Here colour code used is a green colour indicating that the draft is 3 degrees or above, the red colour indicated that the draft is 0 degrees and the blue colour indicated that the draft is in a negative direction which is a minus value.
from draft analysis of class, A surfaces, we can see that green colour is all over the surface which means the surface is suitable for further process and it qualified for optimum draft angle.
Draft analysis of the solid model is similar to the way of draft analysis of surface A. check the solid part to whether it possesses the required draft. here we can see that on top it shows green which is a positive draft and on the bottom shows blue which is a negative draft. That is this solid model possess the ease of ejection from the mould. The colour code is a green colour indicating that the draft is 3 degrees or above, the red colour indicated that the draft is 0 degrees and the blue colour indicated that the draft is in a negative direction which is a minus value.
