Week 9 - Project - A pillar Design with Master Section
AIM
To construct A piller with master section
PROCEDURE
The main parts we gone construct is TOOLING AXIS, CLASS B, CLASS C, DOG HOUSE AND LOCATORS.
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 3 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. I got to know the thinkness of part by measuring the master section.
Now fill that gaps with help of multi-section surface tool, fill tool, etc. After filling that gaps once check the offset part with boundary tool whether all the gaps are filled. Now the CLASS B is created
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 87 deg angle with 4mm length and select the outer arrow mark to get CLASS B gets the parting line.
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.
MASTER SECTION
the mastersection is given for dog house so we have to construct it.
Now we have constructed as per the mastersection.
LOCATOR
Insert a new geometrical set for LOCATOR. For LOCATORS there two type one 4 WAY LOCATORS and 2 WAY LOCATORS, for this DOOR TRIM we gone create 4 WAY LOCATORS. Draw a + symbol line on the surface with certain length
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. The draft angle should be 3 deg.
RESULT
Hence we have constructed the A piller as per the mastersections
