Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

REPORT:

TOOLING AXIS :

THE CREATION OF THE TOOLING AXIS IS THROUGH LINE COMMAND ( POINT AND DIRECTION ). USING THE EXTRACT( EXTRACT 6 ) OF A SURFACE.

B SURFACE :

THE B SURFACE IS CREATED BY EXTRACTING THE A SURFACE IN TO 4 PATCHES( EXTRACT 2,3,4 AND 5) AND THEN EXTRAPOLATING IN SUCH A WAY THAT THEY INTERSECT EACH OTHER AND AT LAST TRIMMING THE SURFACES TO GET THE REQUIRED B SURFACE.

C SURFACE:

THE A SURFACE BOUNDARIES ARE SWEPT USING SWEEP COMMAND AT 3 DEGREES( DRAFTING DIRECTION ) IE,SWEEP 1 AND 2 .

SWEEP 3 AND 4 IS AT 90 DEGREES USING REFERENCE SURFACE.

THE SWEEPS ARE TRIMMED WITH A SURFACE TO GET THE REQUIRED SURFACE A+C

A+C-B:

THE A+C-B SURFACE IS GOT BY TRIMMING A+C AND B SURFACES THEN CLOSED USING CLOSE SURFACE COMMAND.

ENGINEERING FEATURES:

4 WAY LOCATOR :

A PLANE IS CREATED ON THE SURFACE AND AT THE GIVEN POINT + SHAPE IS DRAWN AT 15 CM LENGTH AND THEN USING THE PAD SURFACE EXTENDED .

A DRAFT OF 0.5 DEGREES IS GIVEN ALONG TOOLING AXIS BY TAKING THE BASE AS THE NEUTRAL ELEMENT.IT IS THEN CHAMFERED AT 3MM ONM THE EDGES OF TOP SURFACE. AND THE LOCATOR IS FILLETED WITH 0.25 MM AND UNION TRIMMED TO THE CLOSED SURFACE

HEAT STAKES.

THE CYLINDER IS FORMED BY 5 AND 7 UNITS AS RADIUS THEN THE RIBS ARE ATTACHED AT 6 UNITS HEIGHT AND THEN UNION TRIMMED TO THE CLOSED SURFACE .

THE HEAT STAKES AND LOCATORS ARE COPIED TO THEIR RESPECTIVE POINTS USING COPY AND PASTE COMMAND.

THE DRAFT ANALYSIS IS DONE AT 0.49 DEGREES WHERE THE SURFACE ARE COMPLETELY DRAFTED .
