Ahh - Thank you.
When I first started working with Fadals at my present job, I was shown a quick way to set a part origin (That they would use for engraving) by typing "SETX" enter, "SETY" enter, and "SL,1" enter...
Thanks, Larry - interesting about the Fadal being more precise than the others.
I didn't get an answer here soon enough, so I just went ahead and experimented. Found some peck tapping programs...
So, I learned since my first post about this below that the spindle WILL stay synchronized - someone told me about "peck tapping". But I'm still wondering - can I add an M1 between each command for...
Thanks for your input, Jim and rcs.
Yes, I forgot to mention - rigid tapping. As far as oversize holes: yeah, naturally, you can't go as far with a fine thread as with a coarse thread. I'm going...
I'm putting 1/4-28 threads into some 303 stainless fasteners I'm making. Blind hole in parts 1" long, so drilling .950 deep and minimum thread depth is called out at .750 (Why they need a 1/4" fine...
Regarding a 1993 Fadal VMC3016 with rigid tapping:
If I have an M1 after tapping a hole to a particular depth (To blow out chips/oil), can I program to go back in a second time (deeper) and expect...

Thanks for the input. I called Fadal, as well, and of course they said Vactra 2 for the screws/ways and Turbine oil (Was DTE 797, now replaced by DTE 732) for the spindle. I've got my boss...
I'm working for a company that has a old Lodge & Shipley lathe with 11-inch diameter, 6-jaw chuck. It's really tough to get a part to not runout badly. You can feel when you're tightening down on a...
My employer has two Fadals which I'm running. One is a 1993 3016 that has a single lubrication reservoir, pneumatically operated. The other is a 1985 4020 which has a manually operated...
Thanks for the input, guys. Yeah - I don't know why somebody would spec a #10 hole with threads 1 inch deep. I'm just doing what the customer's print says.
So, I decided I needed to try...
So far, my experience with spiral flute taps hasn't been great; they just seem to be too fragile, even in aluminum. Obviously, very desirable for getting the chips up and out the top of a blind...
No, pretty sure that's not it. I know the machine uses the diameter for the D value, and the width of the slot is perfect - only the ends are each .015 short - that's what's so strange.
Thanks, rodney!
I wrote this simple program today for finishing a slot (I've omitted the first part which is roughing.). Please see the sketch and code I wrote. One problem which I can't figure out: The finished...

Although I've been in the business for over 30 years, I've managed to never tap with a CNC mill before. New place I'm working at has a Fadal VMC4020 and I need to be able to do this with it. I...
For many years, I've located the Z axis of my work coordinate origin by always keeping a sharp-pointed engraving bit in tool position #1 (It was used frequently, as well.) and touching this to the...

Thank you, I remember now that's what I did in the past... it's been a while, and the software I'm using wasn't making any solutions apparent.

Occasionally, I must drill several hundred small holes, depth about 12 x diameter, in a phenolic board. I use carbide circuit board drills which are limited to about .3" depth. So, for these deeper...
