Steel Flanges Drilled & Tapped

- I received a small batch of 6 steel flanges that needed two sets of bolt hole patterns drilled and drilled & tapped. This was a great opportunity to continue learning how to use Fusion 360 to create a CAM program to machine these parts. We used the @MilltronicsUSAInc TRM3016 to complete this job and it worked out great. When I tackle these jobs with the cnc machine I am always learning something new, either from the outcome or the mistakes I made along the way.

In 1981 I was an engineering student at Southern Tech in Marietta, Georgia. One of my instructors had married together a milling machine with a rudimentary computer that was programmed by holes in paper tape. At that point all it would do is make monogrammed belt buckles. CNC has come a long way! ……although, now that I think of it, that was 43 years ago. I’m so old.
Ive done literal hundreds if not thousands of different parts that needed to be clamped down in the machine. If I can say just one thing that will save you a ton of headache; Make sure your clearence height between every operation is higher than your tallest clamp-setup. Depending on your machine it might make the part take a little longer to finish but nobody wants to see the machine try to rapid feed a large drill sideways through a clamp.
Make your clearance plane like 2 inches above the part and your rapid moves will clear and you don’t have to pucker up so much!
When performing this type work I always prefer to have the retract height set to approx. 2" to clear all the clamps, you are doing great!
Just increase youre safety height , so youre tools travel at a higher point.
working with clamps it worth having your retract to 2" in travel, peace of mind and cheaper then breaking tools
from one Old Learner to another: yes, doing is the best training; making mistakes is the very best teacher
Was any body else screaming at the screen around 20 minutes in, saying "increase your z clearance!" He must of heard us.
Sorry, just now I saw that you did just that, raise Z clearance. By my expirience it is better to lose few seconds then crash tool (I crashed my machine many times and mostly on “simple” jobs like this). Keep up with good work!
you could have changed the pattern for clearance too. instead of going around the part, use a star pattern.
I don’t know about machining. I would had placed the old part,. On top of the new part and drill through.
thx for this 🏅 .... a very profound & very detailed explanation for a noob like me 👏🏻
Thank you for making these video's.
In the future, it is helpful to set your Z clearance to move well above the clamp and then rapid down to .200 above surface then go to machining speeds you will breathe a lot easier
Nice job 👍
Abom I know in a book somewhere there is a chart for laying out bolt circles from 3 holes up to like 60. Starts with a bolt circle I would like to add this book to my collection I’m sure. You know what it is.
Overreacting much? Or you don't trust your machine's accuracy? That's plenty of clearance for a machine that's worth thousands of dollars
Hi Adam If these are a regular thing would there be a benefit in making 2 or 3 alignments posts to screw into the base plate instead of using the blocks and clamps to align the flange
Hi, as a beginner home machinist. I have never seen any kind of CNC programs, I think this is fascinating, this is such a time saver if you're making more than one piece.
use a G98 for canned cycles, in the tool offset call line go G43 H# (as per Tool) Z1. then G83 Z-1.25 R0.1 Q0.1 F10. (Cannes cycles as needed) So many things you could look at. punch the carbide drill though in G81
