Chamfered edges for turning

[BillB]

What is the best way to break edges for simple deburring or to add a small chamfer to the edges of your part for turning in CNC12 Lathe?

I program them in profile and cut off cycle.

In Intercon, from the main screen, if you press F10 Other you will then see F8 Chamfer and F9 Radius. That is one way.

Like Uwe, I prefer to use the profile cycle for most of my turning jobs. Just about every Profile move cycle has a "Connect Type" entry. You can directly program a chamfer or radius from there. The downside to this method is the chamfer/radius portion of the cut is run at the same feedrate as the main portion of the move.

If you are turning along with a 0.004"/rev feed rate and then add a 0.010" chamfer, that edge break will be made with only 2.5 rotations of the spindle.

Because of this, I prefer to leave connect type set to none and program my chamfers and radii as individual line and arc segments within the profile so I can enter a much slower finish pass feedrate for these items.

Is there an option to chamfer on a non cut off sides of an edge/s. ? I realize this dose not really make sense as a function of a cut off Machining operation but just a thought, a way to cheat the system. ?

in Intercon, use Groove instead of CutOff cycle to chamfer both sides.

Im looking at it in Intercon and I don't see a way to hit 2 surfaces? Can you create a chamfer on 2 edges in a single grooving operation OR do you need to create 2 sperate operations?

Do you happen to have a file you can share to give me an example?

pls read lathe manual 8.12

left cutoff, right groove

Groove can not go deeper than a tiny bit before X0

Thanks for this

After my 2nd session in Intercon doing the 2nd turotral ( threaded part) making a profile I dont think I will be learning anymore Intercon. I like it for really simple stuff, pretty cool cuz its fast but for drawing it's archaic for drawing profiles, it's like cavemen drawing on rock walls. Im a CAD designer, Ill stick to Fusion and Rhino for my CAD/CAM work and use what I already know. I figure I always have to weigh my options when it comes to learning "more software" Ive learned it all from general 3D modeling, paramedics, surfacing, mesh modeling, sub-D on meshes and surfaces, digital sculpting, etc. If I'm going to spend all this time learning a new software process I could spend the same time learning "more" about Fusion CAM instead of going back to cave paintings, LOL. Maybe Ill change my mind but that's what I'm feeling after last night's 1st session drawing a profile. After my 1st really simple nonprofile drawing part I was excited about Intercon but after my 1st profile, Im disappointed its not better.

Hope I dont offend anyone but be nice if your when your drawing a profile you could actually draw it with a polyline on the fly with simple mouse clicks like any modern CAM software in sketch mode. Im old and I AM "OLD SCHOOL" but this is just to OLD tech for me. IMHO Centroid should reconsider the CAM side of their software.

What is your take on this guys? Would love to hear what others have to say on this subject who uses other CAD/CAM packages for use with Acorn CNC?

Well a turned part is only a profile rotated around the Z-axis, there is no fancy shaded 3D model needed, it makes processing from idea to part only slower for me

On my job I have a CAM system with complete machine and toolholder models, cool for complex turn-milling, but if I wirte like a caveman g-code, my programs are usually running 5-10s per min faster
