Door Arm Rest Week 8 Challenge
AIM :DOOR ARM REST DESIGN USING CLASS A SURFACE
DESCRIPTION : DOOR ARM REST SURFCAE & PART BODY OF 2.5 mm thickness USING CLASS A SURFACE .TOOLING AXIS & DRAFT ANALYSIS CREATION.
To make the part to an angle dirtection. sothat the part model can be easily removed from the model cavity-core. & also acts as the guide curve to make the sweep direction in c surface at an angle of 3deg as the OEM FOLLOW.
DRAFT ANALYSIS
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 that we can create the line on the class a surface
Extract the bottom surface of the class a surface & create the point on it using on surface otion & value is zero . create the line through z axis with point referance .the obtained line is tooling axis.thicken it & change the colour for easily visible.
after the creation of the tooling axis create the SURFACE referance * point ok
intersect the class A surface in to two parts in the xy direction , intersect the part through xy plane & the part referance the inetrcation line if visible through that draw the point to point lines & draw the bisection line that is the another tooling axis .
create the point to point line both side of the dummy tooling axis.with that two line create the bysecting line by selecting two line .that is the main tooling axis for draft analysis.
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-is used to make the part thicken by the class A,B& C SURFACES at required dimensions.
TOOLING AXIS- it is used to sweep the surface at required direction as draft direction referance element.
I HAVE CREATED THE TWO TOOLINNG AXISS AS PER THE REQUIREMENT TO CLEAR THE DRAFT ANALYSIS ON THE PART.
RESULT the closed surface is obtained after the clearance of class A,B& C SURFACES joining togeather with no gap and used close surface command to make the part model into solid.is obtained .& performed the draft analysis on the closed surface part model with two tooling axis.as shown in the below pics.
DRAFT ANALYSIS IN Z DIRECTION WITH TOOLING AXIS IS CLEAR.
DRAFT ANALYSIS IN X DIRECTON WITH TOOLING AXIS IS CLEAR.
