Step 9. Then Luo arkki (“Create sheet”) popped up. I clicked Ok button.

Step 10. Then I clicked Luo osa (“Create part”)

Step 11. I clicked Muotoviiva (“Shape line”) and popped up Muotoviiva windows

Step 12. Then popped up Muotoviiva windows.

Step 13. I checked start/end poins on outside and inside.

Step 14. Then program create start/end poins onto outside and inside

Step 15. I chose Järjestys (“Cutting order”)

Step 16. Then popped up Järjestys window. I clicked Sulje (“Close”) button

Step 17. Then popped up Leikkuu rata (“Cutting path”). I clicked Save cutting file

Step 18. And finally I named and saved cutting file.

I moved file to my memory stick.
3 - Waterjet cutting¶
Aliko watercuter consist of Controll panel and Waterjet cutter.

Step 1. I checked that Water pressure is 3800 bar and Sand speed: 280g /min.

Step 2. I loaded cutting file.


Step 3. I set start point. I moved cutting nose with arrows buttons.

Step 4. I started cutting by clicking Play button

Step 5. At finally I got final cutted object.
