1.PROCEDURE TO MAKE THE TOOLING AXIS:
TWO METHOS WE CAN FOLLOW TO MAKE THE TOOLING AXIS:
A. BY VISUALY CHECKING IN DRECTION TO THE NORMAL SURFACE IF ALL SURFACES ARE PERFECTLY VISIBLE FROM THAT DIRECTION WE CAN CHOOSE IRECTION TO BE DUMMY TOOLING AXIS . THEN DO THE DRAFT ANALYSIS IF FACES COMES GREEN THEN THAT ACXIS CAN BE TAKEN AS MAIN OOLING AXIS:
B. IN CASE THE ALL SURFACES DOES NOT COMES GREEN THEN GO FOR BISECTING METHOD ,WHERE WE TAKE LINE PARALLEL TO TO SURFACES WHICH ARE NOT COMING GREEN AND THEN FIND TOOING.OR IF FEEL BY VISUAL EXAMINIG THAT THIS CAN CAUSE PROBLEM AT THE TIME OF REMOVAL THEN WE USE BISECTINH=G METHOD TO CREATE THE TOOLING AXIS.
C. BY RANDOMLY PLACING THE COMPASS ON ANY SURFACE AND THEN PLAYING WITH IT IN DIFFERENT SURFACE AND DIRECTION TO WHOLE SURFACES GREEN IN DRAFT ANALYSIS.THE POSITION IN WHICH WE FIND THE IT TO BE GREEN THAT COMPASS DIRECTION IS TAKEN AS TOOLING AXIS:
IN THIS CHALLENGE THERE WAS NO SURFACE WHICH GAVE ME INTUTION THAT ,THIS SURFACE WILL CAUSE ANY PROBLEM BECOUSE ALL SURFACES LOOKS VER CLEARLY LEAVING THE CORE EASILY SINCE THEY MAKE VERY GOOD OUTWARD ANGLE WITH ASSUMED TOOLING AXIS.BUT STILL I HAVE USED BISECTING METHOD TO BE CONFIRMED AND NOT DEPEND UPON INTUTION ALONE.
THE ABOVE IMAGE SHOWS THE ASSUMED TOOLING AXIS THAT I HAVE TAKEN.
ABOVE IMAGE SHOWS TOOLING DIRECTION FINDING IN Y DIRECTION:
THE TWO OUTER SURFACES HAS BEEN TKEN INTO ACCOUNT HERE,
STEPS:
1. INTERSETION TAKEN IN ZY PLANE .
2.OPENED SKETCHER WORK BENCH TAKING ZY PLANE.
3.PROJECTION OF TWO OUTER SURFACES TAKEN AS CONSTRUCTION ELMENT.
4.DRAWN TWO PARALLEL CONSTRUCTION LINES PARALLEL TO PROJECT LINE.
5.DRAWN THE BISECTING LINE BETWEEN THESE TWO LINES.
SIMILARY WE DID IT FOR INSIDE SURFACES ALTHOUGH IT WAS NOT TREQUIRED IT MAY HAVE BEEN REQUIRES IF THE SURFACES WOULD BE AS DEPICTED IN BELOW IMAGE:
BUT THE GIVEN SURFACES AS BELOW :
WE ARE NOT REQUIRED TO FOLLOW ABOVE PROCEDURE IN X DIRECTION BECOUSE IN X DIRECTION THERE ARE NO SURFACES WHICH CAN CLING ITSELF TO CORE UPON SHRINKING.
-----------------------------------------------------
DRAFT ANALYSIS:
WE HAVE TAKEN MAIN TOLING AXIS AS DRAFT DIRECTION:
STEP FOLLOWED ARE:
1.WENT TOO INSERT MENU THEN CHOOSEN ANALYSIS:
2.ANALYSIS DIALOG BOX APPEARS.
3. CHOOSE COMPASS SYMBOL DRAFT ANALYSIS DIALOG BOX.
4.MOVE THE COMPASS BY HODING THE RAD SYMBOL AT THE CENTER VERY CAREFULLY WITHOU CAUSING ROTATION AND PLACE IT ON THE TOOLING AXIS.
5.PRESS THE LOCK BUTTON AVAILABLE IN DRAFT ANALYSIS DIALOG BOX.
6.AFTER LOCKING IT RED CROSS WILL COME IN THE CURSOR POINTER ,SELECT ANY FACE AND THE COLOUR OF RAFT WILL BE SHOWN .
7. THE DEGREE OF DRAFT CAN BE SET BY PRESSING THE SYMBOL JUST ABOVE THE LOCKING BUTTON THAT WILL OPEN ONE MORE DIALOG BOX WHERE WE CAN SET THE THE DEGREE FOR DRAFT ANALYSIS.
