Water Jet Flashcards
1
Q
Compare wire EDM to water jet machining
A
+ cleaner, environmentally safe
+ more efficient
+ materials don’t have to be conductive
+ no heat involved, no local change of properties
+ can cut from any point, no start hole needed
- rougher surface
- not as accurate
2
Q
What practices are commonly used for abrasive water jet machining, and nozzle material
A
- silicon carbide
- aluminium oxide
ruby, sapphire or diamond nozzle needed to withstand abrasion
3
Q
When setting up a abrasive water jet in comparison to normal water jet what is the difference
A
- nozzle material changed
- exhaust needed due to particles added
- mixer and vibrator added
4
Q
Abrasive water jet material depths
A
- hole diameter around 0.4mm
- hole depth around 25mm
