Week 9 - Project 1 - Door Applique Design with Engineering Features
Objective:
Create the Door Applique Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.
Answer:
1) Draft Analysis
Draft analysis is done to ensure that the designed part is manufacturable based on the draft conditions applied. It is done to ensure the proper ejection of the component from dies(for metals) or molds(for plastics). The basic idea is to ensure that the tooling axis has to be created in such a wat that it has no parallel surface profiles of the component so that the ejection of the components can be ensured . Tooling axis is the axis along which cavity and core are closed and opened .
2)Procedure for creation of tooling axis using bisecting method .
Step 1: Import the model and check for surface continuity and connectivity using Join tool .Ensure there is no surface gap
Step 2: Insert a geometrical set . Exctract the base surface and create a point at centre of the hole using point on circle option from point tool. Look for suitable axis to create a tooling axis so that all faces clear tooling .
step 3) Use point and direction option to create a line in Y direction .
step 4 ) Let this be our reference tooling axis, name it as tooling axis and publish it .
Procedure to check for Draft analysis
1)Once the tooling axis is created , publish it and the component using Publication from tool option .
2)Insert Feature draft analysis option from insert tool bar
3) Change the view option to customize view parameters and click on material option under shading .
4) Now click on the axis option from Draft analysis tools , allign it with tooling axis and click on lock option to lock it .
5) Change draft angle value to 3 degree . Click on quick analysis mode to display feature according to given color scale . Check from all views to ensure the draft analysis is cleared .
6) Since the created tooling axis does not clear the draft analysis at the created axis , click on the lock axis button to unlock it . Now rotate the tooling axis by left clicking on the top round portion of the axis system . Rotate the axis till maximum clearance is obtained . Now right click on the axis and click lock current axis .
7) Create a line using the initial axis origin and this axis using point and direction (using compass direction) option . This is our required tooling axis .
