There is a switch in the post to turn line numbers on/off. However, if your post is outputting an N number at the toolchange, that would need to be taken out, otherwise you'll get 2 N numbers on that line. Easiest way would be to just load it into Cimco and add line numbers.

or, try a 3fl super-twister. at 10k you can drill at 100 ipm and the holes will come out right on size and location

That's correct. The external thread has a root radius, but the only difference to the internal thread is a slightly larger minor dia.

how bout a five axis threadmilling cycle so's you could mill NPT threads with a straight threadmill?

I've used one, my first concern was with ridigity. I was pleasantly surprised with how rigid it was. For tooling, I was using fixtures that threaded over the spindle nose. I routinely roughed using opti-paths in Alum w/ 20% stepover, .90 depth, and 200ipm @ 9500 No issued with rigidity or accuracy at all

Why are you using C and B? The way ours are set up, look at a "Normal" trunion. A is along the X axis, and that motor is plugged into the "4th axis" connector. The platter, whiched could be called B or C, is called B and is plugged into the 5th axis connector. With a Y axis trunion, everything is hooked up the same, just the actual rotary is bolted down 90 deg off. So B axis is still the platter, A axis is still the trunion. Hook it up that way. Take the out of the box generic Hass TR 5 axis post, change the rot vectors as shown above, set brk_max_ang to 90, and if yo've got the trunion mounted on the right end of the table, set the last Misc Int to 1 so it only rotates positive.

This is how my post is set for posting for a Haas Y axis trunion rotaxis1$ = vecx rotdir1$ = -vecy rotaxis2$ = vecz rotdir2$ = vecy and it' posts correctly

on the linking page, there are options for "follow surface" "retract to feed plane" retract to clearance plane, etc. Try that

Is it a standard trunion or a "Y" trunion?

I'm surprised. I've never run accross anything that wasn't in the Mark's handbook, but not a word about link/ timing belts. My copy is pretty old, but link belts have been around for a long time. Huh? I'd take a look and download the patent. That'll give you the calculations for the teeth

Have you tried the Mark's Standard Handbook? I'll look it up, if and when I ever get home and see. I'm sure it's there.

IMO, the old verify was extremely accurate when you changes the tolerance to around .0002. The default is .008, which is fairly crude. Yes, tightening up the tolerance slows it down, A LOT, but the results are pretty good. Even stil, I've had many instances where verify showed a perfect part, and Vericut showed a gouge.

Are you looking to just set lengths? All our machines have Renishaw tool setters and they work extremely well for setting lengths. Another shop I do programming for has a Parlec toolsetter which is great. Not only for setting lengths, you can check taps, reamers etc. for runout, set boring heads right on the money, and what I like best, you can measure the profile of Form tools. On the downside, the Parlec will set you back the price of a small new car.

Balance would be a concern. Taper accuracy would be too, especially if the tools stick, which could easily screw up your toolchanger. We have gotten some Chinese material in here over the last few years. Horrible to work with. I would really be concerned with the quality of the material, and the heat treatment. I just built a fixture last month, it has four small clamps with 1/4-20 SHCS. I picked up a whole box of them at the hardware store. We're only snuggung these down with a tee handle wrench, but the heads keep popping off. Total PITA. I looked at the box, guess where they're made?

Chinese tool holders??? At $35 ea, after they've F%@#!$ up your spindle, how much have you saved? The other day I needed a little tap handle. I went up to the hardware store and bought one, it was a General Tool. Got back, opened the box and threw it straight into the trash. Completely unusable POS. Guess where it was made?

you need to change the line in your post; brk_max_ang 1 is the default,, Change to to 90

No, not at all. It looks to me like they T/C them underwater, I assume that might help keep the edges from hardening. They will grind all six sides, if you want, but obviously that costs more. If you have any big holes, they can cut those through, saves a ton of time. I've had 6" thick steel plates cut 1/8" over, and it's amazing how straight and square they come out.

I make simple fixtures from aluminum, but rotary and high use fixtures I use torchcut A-36 or J-20. Once I have a fixture drawn up, I email the outline of the pieces to our torchcutter. In a few days they show up all cut to size and Blanchard ground nice and flat for less than I could just order hot rolled plate for.

Verify doesn't show rapid moves, so you can rapid through the part and it won't show. I programmed a gazillion parts with surface high speed w/ min retract and never had a problem. Then, one day, I had the same experience you just had. I always keep it at full retract now. (I also rely on vericut too, it WILL show it)

Check you retract, under linking parameters, set it to full vertical retract. I think the default value is minimum retract. Minimum retract will sometimes trash the part, and it will not show up in verify because they are rapid moves

I set up a camera and filmed a 12 hr long finish cut on an impeller blade. I burned it onto a DVD so now I can sit and watch it at home. As far as coolant protection, don't they make those plastic bubbles for underwater cameras? I was going to say check a camera store, but I think they've al gone the way of the stereo shop.

+1 and add sectional views!!!

We had some carpet cleaners come in last summer, in the morning my mousepad was stolen!!!!!!!!! Sometimes you don't miss something till it's gone

Do a search for Raster to Vector, there are a lot of free downloads. A few years back I needed to load some Topo maps into AutoCAD. At the time we were using V9 and didn't have the option. I don't remember which software I used, but it had a 30 day free trial and it did the trick.
