Autodesk Inventor/CAM/CNC Workflow - Part 10: Finish CAM and Cut Parts on the CNC Machine
In this tutorial series we will be exploring how to use Autodesk Inventor
along with CAM software (CAMBAM) to create CNC parts.
In the 10th and final part of the series we will be showing the final result from design to fabrication on the CNC machine.
We pick up on part 10 by setting the profile in CAMBAM for roughing and finishing. You will notice that the lines are not joined so we need to join and close the lines. This is not done in Inventor so we need to do this in CAMBAM. Click on edit and then join. We use a tolerance of .001. Now all lines should be joined and we can do a roughing and finishing profile.
We press CTRL+T to generate the tool paths. You will notice that only the finishing is able to pass through the separation lines. If you want to adjust this you need to set the spacing to at least .028. We will set the feed rate lower on the roughing to offset this. Next we see the holding tabs. The ones with an X in them will not actually rout. Now we move to the back piece and create a new part for it so it can be run individually if necessary. We set the profile for only a single pass which we have set as drill straight. We have set this to drill straight down and up, without any spiraling. Now we apply the final profiles and then press CTRL+T to see the tool paths.
Now we are ready to create the file and run it on the machine. We will first save the file we have created. Now under the "Machining" tab we will go to "produce gcode" and ask us where we want to save the gcode file. In the video you will see the greenBull CNC cutting out the parts we have created.
