G & M Code: Programming Lathe Canned Cycles | Vlog #77

[@Tito112309]

Finally More lathe videos please !! Thanks for this !!!

[@cncnmore4505]

Titan your badass brother!!!! I was at the G and M code phase when I started watching your videos and they inspired me to just dive into programming ..thank you sir for all that you do to educate people and thank you for your role in keeping manufacturing jobs on our soil!!!!have a blessed day to all reading this is

[@joelovitt2900]

I know I'm 2 yrs late but awesome video. I run an ST 30 and ST 35. I'm new in this field and finding that learning the code and the machines is very challenging. I'm 44 and never went to school for CNC machines or programming. Most days are good except when I have to hunt for job programs or make a new program from using commands from different job cycles. Lol the kid that trains me makes it look easy. When I lived in Michigan I ran a Homag CNC milling machine. It was for cutting sheets of plywood, particle board, melamine or laminated table tops used as furniture. It was a new machine when shipped to our facility and when I finally learned it (about 6 months later) I wanted to become the best (3 years later). However this machine didn't use G&M codes the way Haas does. Point is that when the Homag clicked for me I fell in love with it. I know I will master this machine. You pointed out line for line. The P Q codes always stumps me. 101 and 102 as well. Thank you.

[@DLS_MFG]

I know it’s been a year but to clarify the P and Q and 101 / 102 question. Any line of code can have a N number to identify it. Some programmers put every single line as a n number, starting from N1 and counting up. Some programmer only use a N number at tool changes or other useful points. It’s just a way to identify a line of code. You can’t use the same number twice in a program and it’s best to keep them in order. These types of canned cycles need to know where the first and last line of code is. If you start the cycle at n500 the P in the canned cycle should be “P500”. Same idea for the Q value.

[@PrrWow]

Great video Tyson! I’m the lathe guy at my work. The feed rate in the body of the canned cycle is used by a G70 if you use one. I’ve found that you don’t actually need to put it in cycle at all. You can put it with your G70 line when you use one.

[@peeeoii2738]

X (minor) z (threads length) k(thread height in radial minor-major/2 = THR) d depth of cut (K/ square root of passes wanting to take= Depth) F (feed rate which is equal to pitch so 1/TPI) rpm is not apart of the g76 line of code but is suggested to got 125-150IPM x TPI

[@NoriDavis]

Threading canned cycles are a little more tricky. That would make a great video!

[@MrUnited85]

Awesome video tyson, very clear and very informative. Pops will be proud... BOOM

[@mohamadshamia7057]

I thank you for this clarification

[@Gaming_Biker]

This is pretty much exactly what they're teaching us at my Tech School. Really the only difference is how you're going home. My instructors teach " G28 U0. W0.; ". However, I really like splitting it up to have U & W on separate lines w/ U coming first to avoid ramming the turret into the tail-stock/B-axis spindle. :)

[@thedude5869]

Great video, small tip, put your mo8 on your tool/offset line to ensure the coolant is flowing fully when the tool reaches the part

[@briandennington1984]

Love canned cycles...we used them all the time at my old shop

[@landonjacobs8392]

Thanks titan for teaching me g code it really helps me I decided to just start learning it so if my friends at school need help when setting up a machine I can help them or the teacher can help them.

[@paul5683]

Because we had limited file space on our Fanuc OTA running clausing colchester cnc. One simple facing program. One simple turning program and one simple boring program. Changing starting points depths of cut and geometry was enough to do most of our on machine programming.

[@kisspeteristvan]

On a sinumerik , you automatically have canned cycles , but you can make custom cycles with R variables (on a lathe i know , it had 169 or 199 R variables) . You can almost write a "C+" program for the cycle , let's say a rigid keyway broaching .

[@Zivon23]

Extremely Helpful, Tyson, Thanks for doing this video.

[@benkenny3220]

I wish you guys did the rocket and taught G & M Code for the lathes, like you did for the Mill and 1M part. Good video, thanks.

[@TITANSofCNC]

There is a ton of videos for the Rocket. Will produce more G & M Code videos. Search G & M Code on my channel for lots of videos

[@SirRootes]

Finally, LATHE VIDS! Thanks for the video Tyson. One thing I learnt was I am glad I work on Mazaks! Don't get me wrong I started out on G-code with no canned cycles! But working with Mazaks for the last 10 years, I have been spoilt. lol.

[@raider1628]

Awesome video Tyson!! would love to see your process for cutting jaws in lathe. How you get the id and od diameters to start programming.

[@themotofix5705]

You're really great at explaining things thoroughly. Keep it up!

[@caseyjohnson8427]

I’ve also found that using a type 2 cycle helps with notching on roughing inserts

[@frankr608]

dang ! thanks for laying it down at the control!

[@justinepperson4905]

As as safety precaution and general rule not to crash a lathe, we always program with a G90 on the work offset line G90 G54, G90 G55, etc. Why did you not use a G90 in the work offset line to make sure you weren't accidently in G91 just in case you forgot to run the program visually in graphics? Love the videos fellas

[@alexroman197]

I could be mistaken but the G90 code is mainly for the Mills.

[@justinepperson4905]

@@alexroman197 Thank you for the comment and for correcting me. I have a great deal of more time on mills compared to lathes. In reviewing all of my referencing notes, you are correct. I'm very much out of practice and only run a Mazak laser currently. I miss programming everyday. Thank you though.

[@MummifiedInBarbedWir]

@@justinepperson4905 to add on that X and Y for absolute, U and W for incremental. You can see he is using U and W with the homing G28 code.

[@ilikethisusername2415]

G90 is the default on lathes. No one ever uses G91 in lathes. G91 is only really used with mills to send the spindle home.

[@offuttjr]

Great video , thanks

[@adrian.estrada]

love this type of knowledge Tyson!

[@anthonyjones657]

Tyson's of cnc BOOM! I like that!😂

[@redhousetn73]

Nice. I need more lathe, I am 100% mill hand. This is awesome. There is an ST35Y at work no one knows anything about. I want to get it going.

[@173roberto]

I never understood how to use the G54 in the lathe. My G54 is allways at home coordinates. More lathe videos would be amazing.

[@steinarne79]

Keep it up! Awesome presentation!

[@jaysundaprophet6832]

G72 is canned in the z and 71 is x. Learned all this about 12 years ago

[@tachdriver1]

if i would run a shaft with a follow rest that opens and closes with an m code would i be able to use a haas canned cycle? we have romis at my shop that we have to write every line by hand. Looking at buying haas. would the m code also be repeated using the canned cycle? Thanks for your time.

[@mariocortes1337]

Very educated video thanks a lot!

[@CynHicks]

I tremble a bit at the thought that soon A.I. may actually do this bit of U.I. programming. The possibilities are scary but awesome. The idea of A.I. supplying the framework (source) coding is just wow. Giving the machine an "eye" could be a huge mistake I guess.

[@jaysundaprophet6832]

You don't have to run a finish pass in the same program block you can put G70 in separate block

[@frankcruz1751]

Great videos Tyson. I am currently working on Mills but my boss wants me to learn Lathe and be more familiar with it. Where can I take beginners lathe classes online? I just would like to know more about tips and tricks of it. I understand the controls and how to operate the machine but having trouble understanding canned cycles. Can you refer me to where I can take online classes please?

[@carlosmorales5482]

Thanks for the tips. I'm learning how to use a st20y so it's really helpful.

[@impactodelsurenterprise2440]

I'm torn between outputting cam in canned cycle vs geometry. They both have their pros and cons and I can never decide which is best.

[@krisdougherty2080]

You should show people the different types of canned cycles there's type 1 and type 2 canned cycles(I'm sure you know) also people if you touch off to the face of the part and wanting to take off 1" off make sure and minus 1" on your work offset if not you'll just be cutting air or program G00 Z0.1 G01 Z-1.

[@scottkinkead6324]

If your so worried about saveing time put your z&x and turn on violent on all on the same line

[@scottkinkead6324]

Coolant not violent , dam phone

[@joelovitt2900]

4 fingers is code for 3 lines... Got it.

[@patelharsh8372]

Hello, I have some confusion about turning cycle when Tyson explained about turning down 1.5 to 1 inch dia.He left .01 in U for finishing.In N106 line why he went to X1.0 .Just confused if it should be X 1.01 or not?

[@frankc6012]

Been using canned cycles for years.

[@hemligagosta6554]

if i understand it correctly, the paths of the canned cycles that are used in the roughing passes, is really meant to describe the paths that an eventual finish pass is supposed to go. what i don't understand in this description is the m30 after every part, since m30 sends you home in the program. do you toggle your way back to the start of the next part every time, or how does it work? or do you copy the part into a new program when needed?

[@ilikethisusername2415]

M30 does not send you home. M30 ends the program. The reason he put M30 after every operation is because it's an example program which he copies and pastes from. So if he only needs the roughing portion, he copies that to a new program and runs it. M30 is already there so the program will stop when it's done.

[@jepkeklinge3778]

Nice video Can you make a video about vqc on the lathe as well?

[@davemcclue6226]

Hi Tyson. On your i/d program I see you are starting at X1.5, doesn’t that have to be less than your 1st X diameter in the cycle. Just asking i’m Quite new to this.

[@Sam-sl1uy]

No it was a o/d program

[@Raymond-tn8hp]

Could you do a beginner lathe g-code

[@bebyaguilar3226]

Can you make a program that it shows how to cut a collet with 2 step and pie jaws from the beginning thanks

[@jeevandasan886]

Any idea how to set the tool height offset with a small piece of paper

[@Mik3_S]

Can a G96 go in a G71 cycle?

[@alexgregg2466]

So you don't have to put a retract value in the can cycle line

[@JarppaGuru]

10:12 its not going to be 0.025 it depend on tool radius. 0.8radius it will be small. 1.2 radius there will no chamber. formula cadcam not want you know (1- tan(a/2))*radius = will be how much in z you need make cut bigger. i call it cutter comp xD

[@davidbarnakii99]

Tyson, your canned cycles do not have to go all in one direction. If you added a z value to your first line of code inside the cycle, you are telling the control you are doing a type 2 cycle and not a type one. Haas has a video about type 1 and type two g71 cycles.

[@davidbarnakii99]

@Yeah Right I agree not every control can take a type 2 cycle. But he's on a haas, not another control.

[@monkeymojo073]

Does anyone know how to copy from 'MDI' and paste to program? Is it possible?

[@redleg1013]

Never got to learn the cnc lathe in school beyond theory... so much of what you said was lost on me...

[@vernontan2099]

You say people this？

[@alializadeh8195]

Thanx

[@abdulsamadbc0802]

please send fanuc program of hex making on cnc 2 axis lathe machine

[@johnroberts1768]

Can’t be done if you don’t have a c axis with live tooling

[@muthukumar3724]

❤

[@anddysierraalvarez8216]

G28 U0. And G28 W0. Is bad for cicle time. Is better G53

[@ganapathyperumal3648]

Hi

[@chandrasinghsawadchandrasi5715]

V9comfrom porgram

[@MF175mp]

Boom and then just kiss it

[@richardbooth3213]

That is not a trick it’s a canned cycle ffs

[@ExMachinaEngineering]

I think they meant the trick is to keep it as an auxiliary program with all the safety code and comments you need and just change a few numbers to get to what you want.

[@JarppaGuru]

1:05 yes line from drawing. we not need cadcam

[@JarppaGuru]

12:02 all that changing. could be one liner makro call.

[@J0K3R4Y0U]

Hi. Did you realy nead G50 when you use G96 (G96 is fix S speed)? When you use G95 for VC you need G50 to limit the max. speed.

[@CNCGuy]

G96 is Constant surface speed, G97 is Constant RPM. You need Rpm Cap if you use a G96 S... M3 code.

[@ilikethisusername2415]

G96 is not fixed spindle speed. G97 is fixed spindle speed.
