Objective

To mention what is draft analysis
To mention what is tooling axis
To mention the steps to create tooling axis

Draft Analysis & Tooling axis

This is the analysis which is used to check weather the draft of certain plastic design or material is possible or not. The main requiement for this analysis is Tooling axis for the given plastic component and Class A surface of the component. Tooling axis is the asix which is created by plastic designer which is going to be used as Tooling axis for injection moulding which is the axis were both core and cavity get seperated in most condition tooling axis is created in the place where the component has cenetr hole or on the center surface of the component. Tooling axis is created in center in such a way that all the drafted surface of component measured same draft angle with respective X axis and Y axis. Creation of Tooling axis is different for different component here we used Bisecting method. After creation of tooling axis draft analysis is done the axis is dragged and kept over tooling axis and got locked and direction of draft analysis is given and draft degree is given in scale mostly 3 degree is given. If all surface of component are able to pass 3 degree all surface will be coloured in green. If any surface cannot pass 3 degree to 0 degree it is coloured in red and if any surface below 0 degree it will be coloured in blue colour. Using Cone tool we can measure the angle of the surface.

Creation of Tooling axis:

The Dip surface is extracted
point is created over the center of the surface
Then the new intersect is created with respective x axis
Over the two drafted line the new lines are created and extended to certain distance
Then the new center line is created by bisecting the newly created extended drafted line
Then sketch is made with y axis and the center line is created fpr that drafted surface
New center line is created by bisecting Two center line which is formed from intersect and sketch
All other line are hidden except the newly created center line which is called as Tooling axis
Tooling axis is highlighted in blue colour and thicken too.
