Possibilities include (but are not limited to):
Research¶
I got into familiarize Waterjet cutting process. In the University of Oulu in the Machineshop there is Aliko waterjet cutter. The first I made work plan
Work plan
1 - Object desing 2 - Tool path file 3 - Waterjet cutting
1 - Object desing¶
I designed the object with Autodesk AutoCAD design program. I have documented CAD desingn prosess on Computer Aidid Desing week
2 - Tool path file¶
The next I made tool path file to waterjet cutter. I used IGEMS-program. In the Machineshop they use Finish version of that program.
Step 1. I Open IGEM-program. The first I clicked IGEMS on the left.
Step 2. I clicked Avaa (“Open”) and then Tuo (“Bring”).
Step 3. Then popped up Open window. I chose Circle-01.dxf file and picked Open button.
Step 4. Then popped up Tuo (“Bring”) window. I picked Yes button and located picture of object onto sheet.
Step 5. I cliced Luo (“Create”) button
Step 6. Then popped up Valitse (“Choose”) button. I chose right values such as material: Stainless Steel and thickness: 8.00 mm. I clicked OK button.
Step 7. I chose the object and clicked Enter key.
Step 8. I clicked Luo (“Create”).
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.

Problem and problem-solving¶
I had some problems in use WaterCutter. It was not easy to use first time, but staff in the Machineshop helped me very well.
