I have watched multiple videos on this subject but none of them has been as clear as this. Thank you for spreading your hardly earned knowledge Sir. You’re just an angel!
First Let me thank you for your clear explanation you did in each parameter of the G76 Canned Cycle. Second I would like to ask if possible an explanation on how to program a multy entrance thread.
I have learned a lot from watching your videos, But in every threading video I have see or forum I have read no one discusses how to control the retract. I am trying to do 3/4-10 ID thread and this is very important in my application and having trouble with i
Can you make a video on how to chase threads on a cnc lathe after a part has been unchucked or for repair. How to find your lead thread and how to make it cut correctly?
very new to CNC set up and CODE,,, been making chips by hand for a while but i bought a cnc lathe with a FANUC-O control that uses U and W,,emco lathe with ATC,, a video on how to set up part would be great help! Do an OD tool in X and Z, do a center (spot) drill , ID and OD part to tool set up using the geometry page and the offset page would sure help,, great teachings , thanks
Tom Stikkelman ive learned a great deal from you,, you explain things very clearly and slow enough a person can catch on,,, i truly enjoy all your videos!! I have VERY LITTLE info on my lathe set up but with 4-OD tools and 4-ID tools on an 8 station ATC is what im dealing with,,, the lathe also has tapping ability,,, anything and everything you can think of from set up of the raw-stock to geometry page numbers and wear page numbers (i work in absolute programing) i have an emco pc-55 II lathe about 12yrs old-like new, G97 is default, all straight forward fanu-o,, i thank you ahead of time sir !!!! Again,, thanks so much,,,, no one else would help !!!
I love that you actually explain things this is going to help me alot...so can you use a g76 cycle with a departing tool to take diameter of stock down as well?]
a very precise and detailed explanation as to programing a thread, I am a Mach 3 user and its not a very easy "wizzard" to use, how can I import the program into Mach 3? thank you very much. john
Good work but a fiew question none movie does not explain how to improve the tight thread without losing the whole day on the repetition of the whole cycle of the program? long screws supported by a knife and tailstock for CNC probably do not exist? work tools on several successively forming part of the process of processing the thread with long screws on manual machines is the norm thread 90deg (flat) 3 tools (grove, left side ,right side) for deep trapezoidal threads min 2 tools(growe,final profil) is there a way to set a number of tools so that they can work as a team next opetion in proces threading? how do trapezoidal thread flat, asymmetrical, multi pass snails
Do you know how to program a figure eight grease groove in the bore where a boring tool would plunge in at say Z-.5 and keep threading back and forth in z while increasing depth after 1 pass in and 1 pass out until the groove is to depth.
ok so I'm a mill programmer who has had a SL-35 dropped in my lap. I used your video to figure out how to write the thread program. It put me on the right track but I'm having a fundamentals issues. my thread flank is to wide. what controls that width? I'm guessing insert or maybe speed? any help would be appreciated.
Hi Lee. Yes, instead of starting your tool at the major diameter of your thread and stepping down in a X-minus direction you would start your thread at the minor diameter of your thread and stepping up in a X-plus direction. Hope that makes sense. Thanks.
Great explanation and videos! How would you thread the following: threads on both sides of the part separated by a larger specified OD. I know you would use a LH thread tool and run the spindle CW but how would you program it in 1 setup?
its just same as you see but start point and end point is different. M3 and M4 depending what tool use and if want do right handed or left handed thread. you can do RH tool right handed and left handed thread just switch where start and where end even it wont cut properly :) if you normally run RH tool with M3 from like you see this video. you get right handed thread.if you want right handed thread behind bigger OD you need second RH tool and attack it machine other way and run it from back side using M4 you get right handed thread. you can use same toom in same orientation if it fit to run it. you only need cut groove where it start thread so it not plunge in part :P there is also thread inserts for grooving tools. so it would fit better behind OD just make relief both ends.
+hiran thush The WORKSHIFT works opposite from WORK OFFSET. Make sure to use a G54 offset in your program and then make your adjustments in G54. A positive offset should make part longer.
What control is this for, FANUC? we have a Doosan at work and it uses a 2 line G76, it has a FANUC i-series control, is this the proper code for that machine. I have been skeptical about writing a thread cycle longhand on that machine but have used mastercam on it before. i am comfortable programming threads on Haas, but they use a 1 line G76 and the values are much different.
+Sandman Actual Yes it is for a Fanuc and should work on your Doosan. Have you tried this format in your Doosan lathe? You can just dry run it and see if it will run. Thanks for watching Sandman. Tom
Tom Stikkelman Well, I've seen the code that Mastercam posts and it produced a 2-line G76, Comming from mostly HAAS lathes I just wasn't sure what all of the values meant, especially the pxxxxxx. Your video did an excellent job breaking it down, Thanks.
Depends on the FANUC.. there are three types... G78 does the same thing in the 21TB (type 3, GE series) I've programmed. www.helmancnc.com/fanuc-g-codes-list/
hello sir, i have a kingston machine type CL38C. i have a problem with the alarm code "ex 1034 2nd turred not inposition" what is the solution ,, i expect your answer
tom I have 2 lathes I want to get cnc lathe what book can you recommend I can get and study and what cnc lathe would you recommend I get to start out with
Hi Tom, using this at my job too. Doosan 220 series. Fanuc Control. Why does the controller not accept the decimal on R? We are machining Radius ( R 0009) holding .0004 tolerance. Pitch. Need to adjust the R in the program as no offset for R.
I thing samthing rong. see. haf inch dia metar =12.7-.4405=12.2595 ok then 12.2595÷2=6.12975 ok but you put there p297 why im not andastand can you tell me what is resan that.
I'm not sure where you are getting the 12.7. The outer diameter is .5 inch subtract the minor diameter and divide by 2. Written out in arithmetic it is (.5-.4405) ÷ 2 = .02975 inch
The only thing you will have to do different is make sure your x value in the lines before your G76 line is smaller than your drilled or bore size. I usually go .100 smaller depending on the depth of your thread. It has to have retract clearance or it can rake back across the threads when it comes out of the bore each pass. Hope this helps!
+Tom Stikkelman Hi Tom, you do a great job explaining. I"m having trouble writing code in Mastercam to Mach3 for internal threads. I get error messages in Mach3 mostly saying "Bad Character in Line ...". Do you show any videos explaining how to do this. Thank You! Tex Clauss
+hiran thush If the thread is too big then you can make a tool offset change and restart the threading operation, as long as the chuck or collet has not been opened.
I have watched multiple videos on this subject but none of them has been as clear as this. Thank you for spreading your hardly earned knowledge Sir. You’re just an angel!
Thank you for those kind words. I am glad the videos are helping you.
@@TomStikkelman , you’re very welcome Sir. I was happy to learn that you have served as myself.
Thanks Mr.Tom your an inspiration to all of us.
Very good explanation, clear and concise and without all the hoopla and verbiage! Excellent! Thank you very much!!
thanks all the youtube videos I could find were either in hindi or thick accent. cant believe its hard to find info on this
Hi Tom, after reading many books and a CNC cource, you described it best of all. Thanks!
Thank you Joseph. I appreciate the feedback!
your explanation very clear....i like
Tom that was great. THX.very helpful

I love your videos. They have helped me so much. How would I do a 4 start thread? I have read I just add a Q value?
Good work but a fiew question
none movie does not explain how to improve the tight thread without losing the whole day on the repetition of the whole cycle of the program?
long screws supported by a knife and tailstock for CNC probably do not exist?
work tools on several successively forming part of the process of processing the thread with long screws on manual machines is the norm
thread 90deg (flat) 3 tools (grove, left side ,right side)
for deep trapezoidal threads min 2 tools(growe,final profil)
is there a way to set a number of tools so that they can work as a team next opetion in proces threading?
how do trapezoidal thread flat, asymmetrical, multi pass snails
good day sir, is there a formula on how to picking up the thread after changed the spindle speed(rpm) on g76, in fanuc cnc lathe oi-td

A big thanks
I want to know npd thread,bse thread,metric thread,inch thread. can you please explain about it
Does this work on ID threads? as far as retract goes
Brilliant explaination but i entered your g76 code into mach3 and it had an error NO (X END) any help would be appreciated

hey Tom
would you have a post processor for mazak since you use MasterCAM?
would show a thread cycle using g76 with a NPT for example 1/8-27 thank you
why did we put positive value actualy job legth decrees or increase and viceversa
Sir! How to calculated P(depth of thread) can you help me! Please!
Should I replace the g99 to G95
Please help me.need to cut intenal Acme tread.pitch 5mm but only 4mm deep.id nut is 20.1mm and 27 long .od of bolt 24.
Im trying to add my value but no success.keeps on cross threading.
hi, does mastercam have a post processor for 850sx lathe acramatic?
Nice explanation, but in the first section you say G "oh" instead of G "zero"- that could confuse some beginners.
Hello Tom, What cam software do you use for programming? Thanks for providing these videos.
Hello Mike. I use Mastercam for milling and turning and Partmaker for swiss machines (screw machines ). Thanks for watching. TS
is there a difference on writting the code if your making internal threads?? ty
Hi Lee. Yes, instead of starting your tool at the major diameter of your thread and stepping down in a X-minus direction you would start your thread at the minor diameter of your thread and stepping up in a X-plus direction. Hope that makes sense. Thanks.
i appreciate you
Not compound in feed?
dear tom kindly upload a new video of G76 cycle in metric thread cutting pitch 04 mm
Great explanation and videos!

just make relief both ends.
in the G76 the HAAS SL20 wont do the P030030 it just said bad code does any one know y?
G92 officially is not a canned cycle. It's a repetitive cycle.
Nice!
How to calculate second line P297
in fanuc control cnc lathe we give the positive value in the workshift for reduce job length why did ?

I'm not sure where you are getting the 12.7. The outer diameter is .5

Hi Tom, How do you do internal threads using the G76 cycle ?
+Chris Perkins I will do a video on that soon. Thanks for watching.
The only thing you will have to do different is make sure your x value in the lines before your G76 line is smaller than your drilled or bore size. I usually go .100 smaller depending on the depth of your thread. It has to have retract clearance or it can rake back across the threads when it comes out of the bore each pass. Hope this helps!
why no center? not enough clearance?
Rusty Shackleford no need for it.
So you machined that thread with the first code?
NuttyforNissan Yes I did. Thanks for watching.
