At 81 I just completed building a 4 X 4 CNC DIY router. Now is the time to learn. As I watched the making of these gears, I realized how much I enjoyed the lathe work. Back in the 50's, we had a lathe in the shop where I went to high school. I remember how I loved to mess with it wishing I had something I could build with it beside a head of a small hammer without a hole for the handle. Didn't follow that path, but wonder where I would have gone had I done so.

Funny, right before you switched over to the lathe I was thinking I would do the first op on bar stock in the lathe, forming the bore, steps, and face. Then run the teeth of the mill. I have a 3 jaw chuck mounted on the corner of my DM-2 for holding round stock.

Hi John, Yes Star Trek doors! So, are you using a worm screw to do the opening, or cables?? If worm, you could set the open speed quite fast for 90% of open travel, then ramp down to 0 velocity for the last 10% Closing, probably something OSHA might be comfortable with! What's the detection method, a IR sensor, or wearable trigger device? If the latter, don't forget to transponder the dog!!

.01 too deep or shallow on the backside chamfer? My guess is too deep? Has to do with the way the tool is ground, the tips don’t come to a perfectly sharp angle, or usually don’t, and there is a section of straight vertical flute where the angle meets the bottom. This will cause and issue in your height offsets and needs to be compensated for. It’s similar to how a chamfer mill has a small flat section at its tip and will cause chamfer dimension errors if it’s not compensated for.

What's the point of running the flywheel over the entire surface when the Shear-Hog carved most of it out except the very center?
@Cinnabuns2009
@Cinnabuns2009 7 жыл бұрын
With the single point "seam" right across the center. Yeah was wondering this too. better yet, vs. the shear hog, why not just use an aluminum rougher, encircle the gear full depth, come up and encircle the hub, 1 tool. Finish the face, sides of the hub and face of the gear with finish tool, 2nd tool. Do your detail work on the gear and chamfer. Also, how can you not clock the part when it has an even number of teeth? Don't need soft jaws. Two teeth on top, two teeth on bottom, in the vise, parallels on each side of the hub to supprt. flip the part, run your rougher around the gear teeth in a circle coming in to remove all excess material staying .5 or whatever off the diameter. Rough the rest, finish face and chamfer. Low tool pressure and gtg.
@Hirudin
@Hirudin 7 жыл бұрын
Cinnabuns2009 Holding that gear by two teeth against each jaw of a vise would mean you'd have two narrow strips of contact between the part and each jaw. The contact patch would be basically nothing, it would be like holding a square piece of stock by the corners only. And since the pitch of those gears is probably about 0.75", you'd have over an inch and a half of leverage working against you. You might have noticed that the entire top appears to have been roughed out with the Sheer Hog (1 tool), as you've suggested. Why not full depth? Lack of rigidity is my guess. Once you've removed most of the stock material from around the gear you're left with only a thin piece being held between the jaws of the vises. Taking too rough of a cut with such a small amount of stock remaining could potentially lead to chatter.
@Hirudin
@Hirudin 7 жыл бұрын
ajtrvll Could be force of habit. It's nice to know after the first tool that your stock is at the exact height you think it is and since the SuperFly leaves such a good surface finish and is so efficient at removing material that it's pretty easy to start each job with it. Ever done a facing pass and look at the part to see some of the bar-stock finish is still visible? Maybe the stock wasn't flat or maybe it wasn't seated well in the vise or you messed up with setting the Z-0 point (or a dozen other possible reasons)... Well, if your facing pass is the first op, you can just lower the work offset and start over. No harm no foul. It sucks to have that happen when you've decided not to face the part until half way through the job because you were trying to save 20 seconds of machining.

That's what the parallels are for. They constrain the gear from twist. Sure it won't work using a gigantic cutter with a ton of tool pressure but it works fine when using a 1/2" rougher with very little tool pressure. I've done it so... yeah. Requires no setup, no dicking around with Tabs and what not and programing for an hour. Just flip the part in your 3D software, rotate it to the right alignment, remove the toolpaths you don't need, regen and run. Its not some stupid overly exotic solution but it works. I know he likes the shear hog. Every tool has its place. He uses it way too much for way too many things where its not even close to ideal or quick. Its like saying, "Let's use this 3" shell mill to do an adaptive rough on this gear." Could you do it? Sure. Why would you though? Why would you tell people that's how you're going to do it? For someone like NY CNC who "seems" to put so much thought in to things. There is surprisingly little thought put in to efficient toolpathing and tool choice, and optimal setups which if I don't get as the dude seems to be a smart clever guy.

I always machine bores with an adjustable boring head as I find milling them makes them slightly oval which then makes them run off on the lathe if you use an expanding mandrel.
@JaakkoF
@JaakkoF 7 жыл бұрын
The problem is in your machine if circles become ovals. Backlash, bearings shot, loose gibs, pitch error in screw etc. are all contributing factors. On a Quaser with Heidenhain measuring devices you get true circles within less than 0.01 mm roundness error :)
@cncit

Yes that's fine but most of us can't afford that level of equipment! A boring head is £200-500 and will get less than 0.01mm on a good manual mill..but if you have the machine like a quasar yes you can mill the bores ;-)

@gredangeo
@gredangeo 6 жыл бұрын
Unless the purpose was to show us the tabbing feature or backside chamfer, I figured since you went with the lathe to finish the side, a smarter approach would be to just leave the tab out tool. Bandsaw the excess corners, and face off the whole thing. Also, seems weird that your Diameter offset is that large (.2471). Your toolpath should still be cutting on centerline. The only offset you should be putting in, is the distance you want to go. In Radial. So the number would be (-.0015). The controllers I use at work, always use this logic. Sounds normal to me.

Nick O'Neill It wasn't really that impractical. It prob would have worked out the same, since you'd be taking measurements as you face it on the manual lathe. Maybe 2-3 measurements on the manual, vs one on the CNC. Also, maybe he had a 3 or 4-jaw chuck in the manual lathe, which would have taken even longer.

I think it converts the involute coordinate points to a multiples of close aproximate arc. The later would probably introduce more deviation from a true involute profile, affecting the final rotation accuracy of the gears, vibration, efficiency, noise and longevity.
