Using EdgeCAM to Project Text on a Surface
1. Start by opening EdgeCAM.
2. After EdgeCAM loads you need to select a file to create tool
paths for .
3. Select the Inventor part file with the
surface and double click.
4. 4. Rotate part so that you can see the Isometric View.
5. Autostock the part.
6. 6. You will notice that Origin of the part is not at the top left corner, we will change
that with the “New CPL” command.

9. You will now notice that the new CPL
has been established in the correct place.
10. Now go to the “Manufacturing” Mode.
11. 11. The “Machining Sequence” dialog box now appears. Be
sure to name the sequence, and check that the machine tool is the
prolight 1000, and the initial CPL has changed to what you
named it in step 7. Press “OK”.
12. Select the “Operations” pull down menu
and select “Parallel Lace”
This step is critical!

17. The “Parallel Lace” Dialog
box will now appear, under
the General tab make sure the
offset is (-.01), stepover is 50%
and change the angle to 45
degrees.
18. Open the “Tooling” tab
and “Find” the ¼ inch
ball mill. Make sure the
Feed rates and speeds
are correct.
19. After pressing “OK”, you will

20. In order to create a smoother surface we will create another tool path on the surface but at a
different angle. Repeat steps 12-20. The only difference is the angle of the cut, located on the
general tab, is set to -45 DEG. Press “OK”.
21. With both tool paths complete your
project should look similar to this. Notice
the overlapping tool paths.
22. The last thing we want to do is add text to the surface of the block.
To do this you must go back to the “Design” menu.
23. Once back in the “Design” mode, you need to look at the top of the contour box. To do this, go
down to the “Dynamic” view. Right click and select “Top” view.
24. Once on the top view you can now insert some text on the front of the
box. Select “Geometry” and then “Text”

font type of “Impact”.

36. Then select the text that you created
37. A dialog box will appear, set the “Clearance” to .25 and the “Depth” to -.125. Find a 1/8” Ball
mill and set the feedrates and plunge and speed accordingly.

39. A dialog box will appear set the “Clearance” to .25, “Level” to -.01 and the “Depth” to -.5.
40. Next go to the “General” tab and set the “Offset” to -.01, “Tolerance” .001 and federate, plunge
rate and speeds accordingly. Click “OK”
41. Now you can verify the tool paths the same way as before and if it looks good you can have
EdgeCAM create the toolpath.
