Week 11 - Final project
AIM
to development of a door trim
PROCEDURE
The main parts we gone construct is TOOLING AXIS, CLASS B, CLASS C, HEAT STAKES AND DOG HOUSE.
1. TOOLING AXIS
Before we create TOOLING AXIS, we need to check CLASS A surface whethe it have any disconnectivity in between the CLASS A surface. We can check that by selecting boundary tool which in the operation tool bar. After selecting boundary tool we have select the CLASS A surface and if lines are shown ar boundary of CLASS A surface then there no disconnectivity in between. If any lines are shown in between the ClASS A surface we have close that gap by using joining tool.
After checking that, we have to create TOOLING AXIS for DOOR TRIM.Now insert a new geometrical set for TOOLING AXIS. we can create TOOLING AXIS by selecting measure inertia > create geometry > centre of gravity. Then a point will be created at center of the CLASS A surface. After that select line tool and create line from the created poing towards Y AXIS.
Then go to part design to check the draft analysis for CLASS A.By selecting analysis tool > draft analysis. In that select compass and drag that compass to TOOLING AXIS and lock it. Then select the CLASS A surface, now put the values 2.9 deg for draft angle. Now check the CLASS A surface are green.
2.CLASS B SURFACE
Before constructing CLASS B surface insert a new geometrical set. Select extract tool from operations tool bar and extract CLASS A surface. Now hide CLASS A surface and keep extract part. Then offset the extract part for 2.5mm inside. Now some parts wont be offset but still select ok. Then select boundary tool and click on offset parts and see where are the parts are missing in offset.but in this case there was not single part were missing.
3. CLASS C
Insert a new geometrical set for CLASS C surface. Unhide the CLASS A surfrace, then select boundary tool and click on CLASS A surface. Now the lines are created at edge of CLASS A surface. Then select sweep tool and click on edge lines, then select subtype as with reference surface. Now for guide curve as edge lines and references surface as CLASS A, then give 90 deg angle with 4mm length.
Now check the CLASS C surface with boundary tool whether is there any gaps in between the CLASS C surface.
FINAL TRIM
Insert a new geometrical set for FINAL TRIM. Now join the CLASS C surface with CLASS A surface, then trim that join with CLASS B surface. Then select boundary tool and click on FINAL TRIM to check is there any gap in between the parts, if the error came when selecting the FINAL TRIM then it is fully closed.
Now go to part design to make the soild part from the FINAL TRIM with the help of close surafce tool which is in surface base features.Now the soild part is constructed.
DOG HOUSE
as per the design rules we have constructed the dog house.
DRAFTING ANALYSIS
Insert a new body for draft analysis. Now select draft analysis tool which is in analysis tool bar, then select compass and drag that compass to TOOLING AXIS and lock it. Now select the DOOR TRIM body and check the draft angle of it
RIBS
LOCATORS
ASSEMBLY PART
RESULT
Hence we have constructed the DOOR TRIM as per the design rules
