Hey guys, thanks for the help thus far. I did change my G99 to G98 for per minute feed, to make the bar puller advance onto the part without the chuck spinning. I tried running it on full auto like...

SteveO, thanks. M10, and M11 stick out because they are the chuck clamp/unclamp codes. However, I ran into a new problem...Im doing this so I can use a bar puller. I get my program ran through up...

Hey guys, I just tried that out, and I keep getting alarm 010 - Unuseable G-Code. Does that mean my controller does not support it, or does it mean that I am missing or incorrectly inputting the...

Thanks for the input, Ill give D's advice a try; quick question though. I input my G74 as a double line. I.E.

G74 R.1 <---Escape amount
G74 Z-1.5 Q1500 so on and so forth....

Hello again. I am trying to do a peck drilling cycle in my Leadwell LTC-15 lathe, with a Fanuc-OT controller on it. I have it moving correctly for a G74, however, I want to have the tool retract to...

Well, oddly enough that you say that. We were doing the some work with tungsten, and when we tried to thread it the crests simply fell off. We asked the customer about this, and he said that ALL...

Hello everybody, Im not really sure where to post this, but since its machining Ill post it here. I have a 2.087 Diameter Diamond Coring Drill. My task it to cut a 3 to 4 inch deep core out of a...

Im back again, and with much better results. The speed was much too high for my machine to handle, so I changed RPM's down to 50, and the machine can move fast enough for that, they are most...

Alright, this seems to make a little more sense now. When I originally tried this thread without any help from books, I had it at 1 IPM, which would be 250 IPM, it seemed very fast. Then when I moved...

Im back again, and I think I am pretty close. I decided to go against changing paramaters, and using a shift value; Time is Irrelevant here, I just backed it away. I dont think its perfect, but I...

Hello everyone. I am running a Leadwell LTC-15 2-axis lathe with a Fanuc-OT controller. I have used G32/G76 for thread cutting in the past and it has worked out fine. Now, I need to cut a thread with...

Im just thinking about the insertable cutter right now...Do they sell insertable cutters that are center cutting? It has to be a center cutting tool, the pocket is on the inside, and I must plunge...

10-15 IPM in stainless, really? Only time I get up above 10 is aluminum. Anyways, they are really pressing for this job so I dont think I can even wait for a new tool to come in, Im just gonna have...

This ones a little long, but stick with me on it!

McGyver, I don't have an EDM machine, however even if I did how would that work? Doesnt EDM cut just on the Z axis?

G-Codeguy, If Im not mistaken, there are only roll form taps, correct? Ive never...

You are correct in saying that the crest is breaking off; however as I said before the root of the thread is awesome. As far as turning down the major diameter, the stock we are provided with is...

Well, Im sure its not much help, but at my shop my brother was having the same problems in his CNC mill. I know it was a synthetic water based coolant, but really dont know much else. We machined all...

I have a Leadwell LTC-15 2 axis lathe with a Fanuc-OT controller on it. I found my operators manual, which has basically everything in it, on ebay. They come and go. I am a self taught G-coder, and I...

I dont know how to say this and other way...but WOW!!! I just spent the last hour or so reading every post and looking at every picture, and all I can say is that I am inspired by this entire thread...

Thanks, but as I said, I already machined the OD/ID, but I cannot thread successfully on it. I have had several people tell me to use Poly-crystalline diamond inserts, however Id like to hear some...

Hello. I have a customer who needs me to cut threads on a pure tungsten rod. I have machined I.D./O.D. on it before, and as usual, sharpen the tool many times, and go slow. But, I need to cut a...
