Week 9 - Project - Master Section Development
AIM :DESIGN OF B PILLAR WITH MASTER SECTIONS
DESCRIPTION: CREATION OF THE TOOLING AXIS PERFORMING DRAFT ANALYSISON THE GVEN CLASS A SURFACE & CREATION OF CLASS B & C SURFACE WITH DESIGN RULES & DESIGN OF DOG HOUSE ,4 WAY LOCATORS & RIBS WITH GIVEN MASTER SECTIONS.AS PER THE OEM FOLLOWS.
TOOLING AXIS CREATION it is used to perform draft analysis on the complete part.
MAIN TOOLING AXIS : it is used for the C surface creation .check the correct view that clear the draft , create the plane & point on the master section lines & make bysection line , same as opposite side .by that two lines create the main bysection line the obtained output line is the main toolin axis.thick it & add colour & puublish so that it can easily visible.
SIDE CORE AXIS. This tooling axis is used to apply draft on B side features,(DOGHOUSE & RIBS ) It is created by the same point of main tooling axis line with x direction .
PINK LINE IS MAIN TOOLIONG AXIS
BLUE IS THE SIDE CORE TOOLING AXIS.
FLANGE CREATION it is created by the reference of given class a surface with 2 mm thickness with sweep command.
The pink colour is flange surface
Scein colour is the given class A surface
CLASS BSURFACE CREATION
It is offset with the class a surface of 2 mm
Pink colour surface Is class A
Scien colour surface is class B offset of 2 mm.
CLASS C SURFACE : It is
created by the sweep command by extract the edge of the class a flange with sweep direction of tooling axis of 3 deg angle outside.
Class A B & C surface join.
DOG HOUSE WITH 4 WAY LOCATOR.
RIBS
DRAFT ANGLE of C SURFACE IS 3 deg,DOG HOUSE & 4 WAY LOCATORS IS 0.5 deg,Ribs :0.5 deg
FILLET RADIUS -3mm FOR CHAMFER EDGES & WALLS IS 1mm AS PER DESIGN RULES. min fillet is 0.3 as per required edges.
CHAMFER: 3/45 deg.
DRAFT ANALYSIS performed on class A surface of 3deg deg & also to final component using respective tooling direction & 0.5 with side core tooling axis.
IT is a analysis of a plastic component to determine weather the component is actually feasible to manufacture or not mainly used for thicken the surface.at certain angle (3deg)
REQUIREMENT FOR DRAFT ANALYSIS
solid body
main tooling direction
select material mode
TOOLING AXIS CREATION
Check the correct direction & extract the required surface & create the line with point direction.highlet it so that it can be easily visible .y direction
STEPS FOR DRAFT ANALYSIS
- switch to material mode
- activate feature draft analysis
- place the compass on main tooling direction
- activate compass logo 7 slightly move the compass over MTD line.
- set the angle & colour as per the requirement
GREEN- area clear in main tooling
RED- area have no draft in main tooling
BLUE- area undercut in main tooling
- click on bodu on which draft analysis to be done
- ckeck a surface feasibility.
TYPES OF DRAFT ANALYSIS
catia v5 has two types of draft analysis
1. Quick analysis
2. Full analysis
DRAFT ANALYSIS- it is performed B pillar with master sections using the tooling axis is clear.
TOOLING AXIS- it is used to perform the draft analysis to apply the compass on it to perform the draft analysis.
DRAFT ANALYSIS OF CLASS A IS CLEAR WITH 3 deg.
Red face has 2.7 deg draft
All the edges & the faces of class A & C surface is clear with 3 deg draft except the small patches as shown in the pictures , even that also clear when 2.7 deg draft angle is given.
DRAFT ANALYSIS ON B SURFACE
DRAFT ANALYSIS ON DOG HOUSE OF 0.5deg.
Dog house & 4 way locators are drafted by the lifter axis with 0.5 deg.& 0.4 deg.
DRAFT ANALYSIS ON B PILLAR WITH MASTER SECTIONS WITH MAIN TOOLING AXIS
DRAFT ANALYSIS ON B SURFACE WITH 4 WAY LOCATORS WITH MAIN TOOLING AXIS.
CLOSE BODY OF B PILLAR WITH MASTER SECTIONS
DOG HOUSE & FLANGE WITH MAIN TOOLING AXIS & LIFTER TOOLING AXIS (side core)
SURFACE BODY OF B PILLAR WITH MASTER SECTIONS
FEATURE TREE
RESULT : Design of class B & c surface & close surface is done , dog house & 4 way locators with master sections & ribs & performed draft analysis on the final component is clear.
