Abrasive water jet

Question 1

Advantages?

Answer 1

Small diameter=flexibility
Can cut thick sections
Not sensitive to ctypical hard to cut alloys
no HAZ
Under water to reduce dust

Question 2

Disadvantages

Answer 2

Relatively low speed
Relatively expensive
Oxidation risk
can delaminate materials

Question 3

What is important considering geometry?

Answer 3

Avoid sharp corners and low radius
Avoid small holes in thick materials
Lowest possible hole is nozzle diameter although the tolerances are har to accomplish in thick materials

Question 4

What is importand considering material?

Answer 4

Different materials allows for different speeds, Use software so maximize material utilization

Question 5

Material thickness

Answer 5

Avoid thick materials, if it’s possible to have thinner materials that is better for awj

Question 6

Surface finnish?

Answer 6

Smoother surfaces takes alot longer to make. Dont overspecify
