Week 8 - Challenge 5 - Core & Cavity Design
AIM - CORE & CAVITY DESIGN USING SWITH BEZEL PART MODEL.
DESCRIPTION CREATION OF CORE BOCK & CAVITY BLOCK WITH TOOLING AXIS REFERANCE IN EXTRUDE COMMAND. & CREATE THE PARTING SURFACE & PARTING LINE AND PUBLICATION IT. PERFORM DRAFT ANALYSIS WITH TOOLING AXIS USING 3 deg angle.
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.
PARTING SURFACE To create the parting surface extrapolate the class A surface with required length.& unhide the class c surface & part model (for referance visibility) trim the class a surface with class c surface make sure the upper part is required.& unhisde the class B surface trim class C surface down part. the obtained trim is parting surface after the parting line is created the spliting of the parting line and the parting surface .the obtained split is the actual parting surface ( images are attached below) & PUBLISED IT
PARTING LINE The creation of parting line the intersection of the class b surface with trim ( CLASS A & C SURFACE ) the obtained line is parting line it is thicken & added colour to it for easlily visible.( images attached below) PUBLISED IT
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)
DRAFT ANALYSIS is firstly performed of given class a surface with 3 deg angle with tooling axis is clear after thet the core cavity is designed.
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
create the point at the hole as curve circle,ellipse option
create the line of point direction through z direction & name it as a dummy tool axis change the colour, thickness & axis of the line so that we acan easily identify it.
after the creation of the tooling axis create the plane of yz referance * point ok
intersect the classa surface in to two parts
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. performed draft is clear on the part model.
TOOLING AXIS- it is used to sweep the surface at required direction as draft direction referance element. ensure that use the tooling axis as referance element in sweep command so that the proper draft analysis is obtained.
RESULT The core & cavity blocked is designed with switch bezel part model as referance with draft analysis performance on switch bezel wth tooling axis referance of 3 deg angle. the parting surface & parting line of core & cavity also created.as attached in below images.
