Preparing files for the waterjet

Preparing a cutting file for the waterjet cutter.

 

·         Please use a cad program for the drawing. In the file, have only lines, which will be cut.

.         Take the thickness of the cutting jet, ~1mm, into consideration.

·         Line type and width does not matter.

·         Have the lines on only one plane and layer.

·         Gap between cut items can be 2mm.

·         Export into metric dxf file.

 

From a 2d drawing, simple tilted operations can be machined. Ie. beveled cut or a cut at an certain angle. If your cutting involves more complex geometries or many angled cuts, please send a 3d model.

·         The model should be the same thickness as the material being cut.

·         Maximum angle is 59°

·         Export into metric step file.

 

Small pieces (smaller than your palm), need to be held on to the base material. A simple tab can be created when making the cutting paths at the waterjet, but if you are cutting several items please hold the pieces together with small connecting bridges between the pieces or create a comb connecting the pieces. This way you will be in control where the connections are and can be sure they will on intervene with your design.

When cutting fragile materials please provide more room between each item. For glass 10mm

Workholding for sheet materials take roughly 50mm around the cutting area of the file.

Making files with Rhino3d



Kuva: Rhino3d

Draw cut geometries on one level. Have only cut geometries on the drawing.


Kuva: SelAll

Command SelAll selects all

SelDup selects duplicate lines which can be deleted.


Kuva: Export

Export command lets you save your drawings


Kuva: Tallenna DXF

Save as dxf.


Kuva: tallenna CAM metric

Choose CAM Metric from dxf export options

For advanced use, the layers can be used to determine cutting quality.
