Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

REPORT ON FAN COVER TOOLING AXIS:

AS THE FAN COVER HAS ANGLE ON THE FACES AND CONCAV, CONVEX AND HOLES IN THE Z- DIRECTION I PREFERRED TO CONSIDER MY TOOLING AXIS IN THE Z-DIRECTION WHICH IS VERY EASY METHOD IN WHICH

CORE AND CAVITY ITSELF FORMS MODEL SHAPE. BUT IN THE X AND Y DIRECTION IT WILL BE DIFFICULT TO MAKE MOULD WHICH INVOLVS SOME ADDITIONAL MECHANISM NEEDED . THAT IS SPLIT CAVITY MECHANISM.

I HAVE CREATED THE LINES ON THE TAPERED FACES AND CREATED A ;BISECTING LINE OF THE TWO LLINES THROUGH THE CENTER POINT, THAT IS TOOLING AXIS CLEARING X DIRECTION AND IN THE SAME WAY I HAVE CREATED TOOLING AXIS CLEARING Y DIRECTION AND AND WITH THESE TWO TOOLIN AXIS I HAVE CREATED THE MAIN TOOLING AXIS USING BISECTING LINE METHOD.

REPORT ON THE DRAFT ANALYSIS:

IN ORDER TO HAVE THE CORE AND CAVITY MOVEMENT AND PROPER PART EJECTION DRAFT IS PROVIDED.

IN THE FAN COVER DRAFT ANALYSIS, I HAVE GIVEN MINIMUM DRAFT ANGLE AS THREE DEGREE. AS THE FAN ANGLED FACES HAVE ABOUT 10 DEGREE AND OTHER HORIZONTAL FACES I GOT COMPONENT AS GREEN.

IF THE DRAFT IS BETWEEN 0 AND 3 DEGREE AND EVEN MORE IT IS POSITIVE, IT IS RERESETED BY GREEN COLOUR

IF THE DRAFT IS 0 DEGREE, IT IS RERESETED BY RED COLOUR AND IT IS LESS THAN 0 DEGREE THAT IS NEGATIVE IS REPRESENTED BY BLUE COLOUR. AS THAN FAN COVER HAS POSITIVE DRAFT IS SHOWING GREEN COLOUR
