THREE 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 ARE TWO SURFACES IN Y DIRECION WHICH DOES NOT LOOKS PROBLAMATIC BUT BOTH ARE INCLINED ALONG POSITIVE Y DIRECTION SO DEFINETLY THE Y- DIRECTION TOOLING AXIS WILL NOT BE DUMMY TOOLING AXIS IT WILL INCLINED SOMEWHAT TOWARDS POSITIVE Y IN ZY PLANE.

BELOW IMAGES DEPICT STHE SAME:

DUMMY TOOLING AXIS:(Z AXIS)(FIG.01)

FIG.01

FIG.02

FIG.03

STEPS:
1. INTERSETION TAKEN IN ZY PLANE .(FIG.03)
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.(FIG.02)

-------------------------------

NOW TURN TO FIND TOOLING AXIS IN X DIRECTIO:

NOW HERE WE CAN SEE THAT THERE IS ONLY ONE FACE IN X DIRECTION WHICH CN CAUSE PROBLEM WE WILL MEASURE THE ANGLE WHICH IT IS MAKING WITH Z AXIS AND ITS FOUND TO BE (1.32 DEREE) CAN SEEN IN FIG.05

ALSO WE DONT HAVE ANY OTHER FACE THAT CAN CAUSE PROBLEM IN X DIRECTION WE WL ROTATE THE THE DUMMY AXIS ABOUT Y AXIS IN XZ PLANE BY (2.68 DEGREE) IN OPPOSITE DIRECTION SO CUMMULATIVE ANGLE WILL 4 DGREE 1DEGREE MORE THAN THE REQUIRED TO BE IN SAFER SIDE(FIG.05).AND THAT ROTATED DUMMY AXIS WILL BE OUR TOOLING AXIS IN X DIRECTION.

STEPS:
1. INTERSETION TAKEN IN ZY PLANE .(FIG.04)
2.OPENED SKETCHER WORK BENCH TAKING ZY PLANE.
3.PROJECTION OF OUTER SURFACE TAKEN AS CONSTRUCTION ELMENT.(FIG.05)
4.DRAWN TWO PARALLEL CONSTRUCTION LINES PARALLEL TO PROJECT LINE.
5.DRAWN THE BISECTING LINE BETWEEN THESE TWO LINES.

TO FOLLOW STEP 5 WE HAVE ONE CATCH HERE THAT ,X-TOOLING AXIS AND Y-TOOLING AXIS BOTH ARE AT SOME ANGLE ANGLE TO Z AXIS BT BOTH ARE IN IFFERENT PLANE THAT IS (X-TOOLING AXIS IN : XZ PLANE AND Y -TOOLING AXIS IN :ZY PLANE) AND WE HAVE TO MAIN TOOLING AXIS.

SO I ROTATED THE ZY PLANE BY (2.68 DEGREE ABOUT X AXIS)

AND TOOK THE PROJECTION OF Y-TOOLING AXIS ON THAT PROJECTED PLANE.

--------------------------------------------------------------------------------------------

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.
