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

REPORT ON DESIGNING DOOR TRIM WITH HEAT STAKE AND LOCATORS:-

THE STEPS TAKEN IN DESIGNING ARE AS FOLLOWS:

1.INPUTS-

HERE WE GET AN CLASS A SURFACE AS AN INPUT TO CREATE AN FINAL COMPONENT WHICH IS AS SHOWN IN BELOW IMAGE.

2.TOOLING AXIS CREATION-

TO CREATE AN TOOLING AXIS WE HAVE TO CHECK WHEATHER ALL THE SURFACES ARE VISIBLE ALONG X, Y AND Z AXIS.
IN THIS CASE ALL THE SURFACE ARE VISIBLE ALONG Y AXIS, SO THE TOOLING AXIS WILL BE CREATED ALONG Y DIRECTION. IF SOME OF THE SURFACES ARE NOT VISIBLE THEN GO FOR BISECTING METHOD.
HERE THE SURFACE IS EXTRACTED TO CREATE AN POINT, AT WHICH THE LINE IS DRAWN ALONG Y DIRECTION KNOWN AS TOOLING AXIS WHICH IS AS SHOWN IN BELOW IMAGE.

3.DRAFT ANALYSIS ON A CLASS A SURFACE-

DRAFT ANALYSIS IS DONE TO CHECK WHEATHER THE CLASS A SURFACE CLEARS THE MOULD OR CAVITY ALONG THE TOOLING AXIS OR NOT.
SELECT THE DRAFT ANALYSIS TOOL PLACE A COMPASS ON THE TOOLING AXIS AND LOCK IT, SELECT THE CLASS A SURFACE TO SHOW THE RESULTS IN THE FORM OF COLOUR CODES.
THE MINIMUM OF 3 DEGREE DRAFT NEED TO BE PROVIDED FOR THE SURFACES.

4.CLASS B SURFACE CREATION-

TO CREATE AN CLASS B SURFACE WE HAVE TO OFFSET CLASS A SURFACE TO A REQUIRED THICKNESS, DUE TO WHICH SOME OF THE SURFACES AND FILLETS WILL BE MISSED OUT.
SO BY SOLVING THESE ISSUES CLASS B SURFACE IS CREATED WHICH IS AS SHOWN IN BELOW IMAGES.

5.CLASS C SURFACE CREATION-

TO CREATE AN CLASS C SURFACE WE HAVE TO USE CLASS A SURFACE, WHERE WE HAVE TO CREATE AN BOUNDARY ALONG CLASS A SURFACE AND USING SWEEP COMMAND CLASS C SURFACE IS GENERATED.
PROVIDE 3 DEGREE FOR THE SWEEP IF THE SURFACE IS PARALLEL TO THE TOOLING AXIS OR 90 DEGREE IF THE SURFACES IS PERPENDICULAR TO THE TOOLING AXIS.

6.CLASS A AND CLASS C SURFACE JOIN-

HERE BOTH CLASS A AND CLASS C SURFACES ARE JOINED WHICH IS AS SHOWN IN BELOW IMAGE.

7.FINAL TRIM-

HERE THE JOINED CLASS A AND CLASS C SURFACES ARE TRIMMED WITH CLASS B SURFACE TO GET AN CLOSED BODY SURFACE WHICH IS AS SHOWN IN BELOW IMAGE.

8.CONVERTING CLOSED SURFACE INTO SOLID COMPONENT-

HERE THE CLOSED SURFACE IS CONVERTED INTO SOLID COMPONENT BY USING CLOSE SURFACE TOOL FROM THE PART WORKBENCH WHICH IS AS SHOWN IN BELOW IMAGE.

9.HEAT STAKE WITH RIBS CONSTRUCTION FEATURES-

HERE THE PLANE IS CREATED ON THE GIVEN POINT TO CREATE AN SKETCH OF HEAT STAKE WHICH IS AS SHOWN IN BELOW IMAGE.

THE SKETCH IS THEN EXTRUDED TO A REQUIRED HEIGHT.
THE RIBS FOR THE HEAT STAKE IS DRAWN AND EXTRUDED UPTO REQUIRED HEIGHT AND THEN UNTRIMMED WITH THE HEAT STAKE WHICH IS AS SHOWN IN BELOW IMAGE.

THE NECESSARY CHAMFER, RADIUS AND DRAFT OF 0.5 DEGREE IS GIVEN FOR BOTH HEAT STAKE AND RIBS.

THE HEAT STAKE WITH RIBS IS THEN COPIED AND PASTED (PASTE SPECIAL), WHICH IS THEN POINT TO POINT TRANSLATED ALONG THE GIVEN POINTS AS PER THE DESIGN REQUIREMENT.

10. 4 WAY LOCATOR CONSTRUCTION FEATURES-

TO CREATE AN 4 WAY LOCATOR FIRST EXTRACT THE SURFACE, CREATE A POINT AND DRAW A SKETCH ALONG ZX PLANE WHICH IS AS SHOWN IN BELOW IMAGE.

THE SKETCH IS THEN EXTRUDED AT A HEIGHT WHICH SHOULD BE GREATER THAN THE HEAT STAKE, SO THAT THE LOCATOR SHOULD COMES IN CONTACT WITH THE MATING SURFACE FIRST.
THE NECESSARY CHAMFER, DRAFT AND RADIUS IS FORMED AS PER THE REQUIREMENT WHICH IS AS SHOWN IN BELOW IMAGE.

11.DOOR TRIM FINAL COMPONENT WITH LOCATORS AND HEAT STAKE-

BOTH THE HEAT STAKE WITH RIBS AND LOCATORS ARE UNTRIMMED TO THE DOOR TRIM FINAL COMPONENT WHICH IS AS SHOWN IN BELOW IMAGE.

12.DRAFT ANALYSIS ON A FINAL COMPONENT-

HERE DRAFT ANALYSIS ON A FINAL COMPONENT IS SIMILAR TO THE DRAFT ANALYSIS ON A CLASS A SURFACE, INSTEAD OF SELECTING ON CLASS A SELECT ON FINAL COMPONENT AND THE RESULTS ARE IN THE FORM OF COLOUR CODES WHICH IS AS SHOWN IN BELOW IMAGE.

13.PUBLICATIONS-

THE CLASS A, CLASS B, CLASS C SURFACE AND TOOLING AXIS ARE PUBLISHED WHICH IS AS SHOWN IN BELOW IMAGE TREE STRUCTURE.

14.ORIENTATION VIEWS-
