DETAIL REPORT -

DRAFT - THE DRAFT IS PROVIDING ANGLES OR TAPERS ON PRODUCT FEATURES SUCH AS WALLS,RIBS,POSTS AND BOSSES THAT LIE TO THE DIRECTION OF RELEASE FROM THE MOLD EASES PART EJECTION.

THE MINIMUM DRAFT IS SHOULD RANGE BETWEEN 0.5 DEGREE TO 1 DEGREE . THE NOMINAL DRAFT FOR A COMPONENT OR PART IS 3 DEGREE.

IN CATIA WE USE THE DRAFT ANALYSIS OPITION TO CREATE THE DRAFT TO THE PART OR COMPONENT. WE CREATE THE DRAFT ANALYSIS WE SHOULD REQUIRE THE TOOLING AXIS .

TO CREATE A TOOLING AXIS -

STEP 1 : FIRSTLY TO SELECT A SUTIABLE AXIS FOR THE PART AND EXTRACT THE SURFACE FROM CLASS A .

STEP 2 : CREATE A POINT ON THE SURFACE AND CREATE A AXIS SYSTEM ON THAT POINT .

STEP 3 : SELECT THE YZ PLANE AND DRAW THE LINES PARALLEL OF THE PART AND CREATE A BISECT LINE FROM THE TWO LINES.

STEP 4 : AND SELECT THE PLANE XZ AND CREATE A LINE FROM THE INTERSECTING PART .

STEP 5 : THEN YOU HAVE TWO LINES AND USING THE BISECT LINE OPTION TO CREATE A BISECT LINE THAT IS THE MAIN TOOLING AXIS LINE .

STEP 6 : BY THE USING THE TOOLING AXIS LINE TO CREATE THE DRAFT ANALYSIS.
