At 2:21 there's a graphic error of ".2325", which is wrong. It was supposed to display ".257" for the drill size. Sorry for the mix up!

[TITANSofCNC]

Hope you guys enjoyed this video! I've been getting asked a lot to do more manual programming tutorials. What other specific manual programming tutorials would you like to see?

[flyingjeep]

Why is the G40 covered up? I would get an alarm with this because the of there being no G40.

[wethenorth]

Should teach this with single point thread mills. And have a tutorial on G02 and G03 with I' s and J' s. Leading in and out with a arc

[Daniel-lqrg]

From experience, it's usually best to arc into and out of the cut instead of going straight G01 into the part for an improved tool life.

Re: cutter comp. the ancient machines at my school (fadal) require a 90 degree x or y move to the first cutting plane (larger than the radius of the tool) to engage cutter comp. it doesn’t look like you needed to do that with your controller. Am I seeing/understanding this correctly? I know all machine controllers have their own ways of using/requiring the input to some extent.

I work for Northrop Grumman as a prototype programmer machinist. I plan program and manufacture all my parts. These parts are no quotes from hundreds of vendors. There are 4 of us in the machine shop. At a facility that has 5000 employees. How do I apply to your company.

Titan, learning manual programming is the best. Thank you for your very generous contribution to an industry that has treated me very well. I am a certified general machinist, working on CNC since the beginning for over 30 yrs.

A simple trick or saying I learned for using I&J in G02/G03 is, (remember it as you are the cutter) "Where is arc center to me"? This number is the actual distance (incremental) from where you the cutter are, to the center of the arc that you are programming.

Titan, I noticed a safety area that I always use to this day (which has saved me more than you know) is on the G43 line, [ G43 H12 Z5. ] the "Z5." used in conjunction with single block, gives a safe position to stop that a tape measure or gage block can tell you if you are at 5.0" or something is already wrong. Even Z2.0" is better than running in rapid to Z0.10" of within the part. I even have the posts for cam programs changed to output this as a master start point!

With the speeds of the machines these days, we all need habits in programming that build in safety to help reduce hitting the parts or worse crashing the machines.

[caploader]

Why no G40 to cancel cutter comp? Is there a parameter to avoid an alarm? Im thinking that if theres no value for D4 there will not be an alarm but if there was a value in tool geometry the machine would have alarmed out.

[vimalsoma]

Boom Boom Boom Boom!! Is Titan a fan of John Lee Hooker??

[neilmcdonald]

How about plunge milling to remove alot of material with an incremental stepover, similar to your recent video with the large 45deg angle.

[davekearley]

One thread mill for many sizes reduces need in machine 32 thread mill can do 6-32, 6-32 helicoil 8-32 8-32helicoil and 10-32 same tool.

Have macro just G65Pxxxx D=(thread OD) E=(pitch) F=(feed)R=(rapid plane)S=(speed FT/min) T=(tool dia)Z=Depth)
G65Pxxxx D0.25 E28 F500 R.25 S100 T.125 Z-.4

Titan, just trying to help you cut out a step. When copying and pasting in edit mode there is no need to go to memory and back to edit. All you have to do is press the undo button and stay in edit. Love what you're doing brother. Press forward!

[crisbraun]

Titan. I have an important question. I need to "Clock" a Thread on a 9mm Barrel with a Thread Mill. The Barrel will be finish machined, and the end of the Muzzle will be turned to Ø.496
The Thread is a 1/2-28 - UNEF 2A. I have a ±4° window to work with on this. It will be for a Compensator. This will be set-up on a Doosan 4500 Mill with a 4th axis. Probably use a vise on the bed for positive location and repetition. Any help would be appriciated.
Thank you Sir.

[johntunnard]

Titan, these g & m code vlogs are excellent. Banking all this valuable information. Moving shops next week, to a company who have the largest number of haas machines in the uk. Been using cam and conversational last 5 years, so these videos are really giving me a way back in. Thank you so much Titan, love you man!

[thomastate]

I have been waiting for this. My dad just bought a Kennametal Thread Mill and I have no clue how to use it. So this helps a lot. Thanks Titan.

[skimanization]

Good video lesson, as a novice, like a child, I'm learning a lot, I'm not an engineer as a production line worker I'm always exposed to these machines and engineers. I want to know how their doing what they are doing on a daily bases. Thanks.

[chrisranly]

Been looking for a while... Titan love your work, show me how to program an NPT thread with a single point thread mill. I use edgecam and it doesn't have anything for this. I'd like to just program it by hand at the control. Can ya do it??

[Chiefs]

This has nothing to do with the part I'm making thread Milling with the X and C axis for some reason the machine doesn't pick up polar interpolation machine is a Hyundai l4000 pick up polar is that a parameter tia

[kdenyer]

When I was doing programming always arced in. This gave a smother eatery and nicer thread.
