Sometimes the best way to do something is the slow way to do it. If its slow, but doesn't cause chaos, it's actually fast. Slow is smooth, and smooth is fast

[@EdgePrecision]

This is what I have observed over the years. Speed is way overrated. What is important is consistency. One of Titans recent videos he talks about metal removable rate is the most important thing. I don’t necessarily agree. What is important is completing the job with the least cost in time and materials and labor. If you spend a lot to go fast where is the economy? I have known machinists that don’t look fast but make the most money for the company. Consistency!

[@WCGwkf]

Great camera work and process! might have a new sub here. If you were running 316 stainless or 17-4 mill or turn, would you personally run it all without coolant or with it? Is carbide coating grade part of that decision? Only part I know I'd run coolant for sure is a 8" deep 3/8 drill hole. I've only turned 316 on a manual lathe with some oil and carbide inserts and it ran fine but I'm hoping to be buying some machines and running production soon.

[@raystanczak4277]

Would it be possible to plug those holes with steel plugs, and remove them when you’re done?

[@JamesKC3OXN]

Don't worry about explaining why you've decided to run something conservatively. Those of us who know already know. Let the haters hate and keep the content coming.

[@PeregrineBF]

I'm not a machinist, so I don't know. It's nice to have the explanation.

[@jimsvideos7201]

Do you know if the shiny patches downwind of those holes are a finer finish, or just shiny?

[@florianpohl3735]

Hey peter, At first thx for showing your job. Maybe next time you can mill out a groove around the intermittent cut and then start turning. We do it at our shop and getting pretty good results. We leave just 0,4mm if Stock with the mill so it won’t effect the finishing cut to much. Again thx for your afford.

[@EdgePrecision]

Yes I have done that in the past. But for one part like this it's easier/simpler (and faster) just to override the feed in the holes. The only reason (I think)I broke the insert is not slowing it down soon enough.

[@papapetad]

I know roughly sfa about machining but the first thing I thought of when you spoke of the holes posing a problem for the cutting tool was chamfering... Wouldn't it help with the less aggressive angle of attack?

[@Awfultyming]

Awesome, as always, but how do you measure that? I know you've said before you dont really use the CMM you have. I dont ever work on anything that big so I'm sure I'm missing something (or several somethings) but making sure each pocket is in the right position seems difficult

[@EdgePrecision]

Nothing about this job was critical. Everything was +-.010”. So calipers and the mic you saw was sufficient.

[@ShInYaKu88]

You´re insane :D

[@captcarlos]

Good video, I was anticipating you finishing those pockets in 5 axis. The worst crash I've had was opperating two machines at once without backing down feeds and speeds... Disaster.

[@EdgePrecision]

I thought about it, for the sake of the video. But I was in a hurry to complete the job while I was running the horizontal mill. But it would have been interesting to do it.

[@captcarlos]

I just thought it would reduce the after work and also give the path for a deburr chamfer pass. Aaand, I would love to se you touch up that endmill you roughed with.. Really enjoy watching your CNC tool grinder in action!

[@bcbloc02]

[@vilchezjo]

...gracias

[@user-pb5nc3vh6j]

Hi Peter! Great work as always! Watching your videos is a relief for me, as now I work only at VMC and used to work at lathe with milling capabilities,kinda miss those times. I wonder why don't you use "C" axis to mill those notches simultaneously either dividing operations? just interested)))

[@EdgePrecision]

I did experiment with a C axis type of program but it didn't really work better. Remember I wanted this to run unattended while I was over at the horizontal mill.

[@handdancin]

since you have live tooling, i wonder if you turned the part so the holes are up, then milled slots along the y axis, where the holes are, so that its close to final diameter just where the hole is, and tapers out back to the original OD above and below the hole. maybe that would save a lot of impacts on the turning insert. hope that makes sense

[@EdgePrecision]

I have done this in the past. Taken a endmill and mill a groove the width of the hole close to the finish diameter by rotating the C axis. In this case I could even start in the hole. That will solve the problem. But for this one part it’s just easer and less time to override the feed.

[@handdancin]

@@EdgePrecision cool, appreciaye the reply. makes sense

[@josephweaver7140]

IMO, It is efficient. It's not efficient for that one part, but it is efficient for your workload at that time. Working 2 jobs at once, however inefficient for each individual job, is more efficient overall.

[@brianbob7514]

Will you be able to cut those extra jaw parts off of that chuck?

[@DancingMachine1]

I always use end mills with flat cutting edges like you in this video. I also tried roughing end mills with these ripped edges, but I think they don't really last longer and the surface finish is bad obviously. Do you ever use these mills? In which way are they better? Greetings from GER

[@EdgePrecision]

In the old days when we used HSco tools these roughing endmills worked (They were really the only good way). But I have tried them in carbide and they don't work. I think it has to do with re-cutting the chips and the way the tips of the rippled edged wear out, or over heat at the high surface speed carbide runs at. This is old technology that really isn't used much anymore. Unless your working on old equipment that runs at slower speeds.

[@ksanalyticalsystems2438]

Did you hear the insert break or notice some other change? I have frequently been "surprised" by a chipped insert after the cut is finished.

[@dav1dsm1th]

I'd imagine the sound of the operation changed dramatically as the broken and displaced insert gouged that ring out of the part.

[@3axisrocks393]

Im using Featurecam for 2 axis lathes, XZC live lathes and 3/4axis VMCs. We're planning on buying an Integrex and Im wondering if its worth keep using it or trying Esprit.

[@EdgePrecision]

I looked at Featurcam a while ago. It doesn’t even come close to Esprit TNG for running this type of machine. But Esprit is expensive.

[@neilwoodward7336]

I completely relate to slowing things down and being conservative when you're trying to run another machine. Never sacrifice your quality & attention for speed. Its better to finish both parts properly than to scrap 1 or both.

[@drumperson10]

Do you have to wait for the part to cool before measuring?

[@EdgePrecision]

If you are working to close tolerances most defiantly yes. You notice in the video when I’m measuring the part with the mic. I’m touching the part. I didn’t think about it till you mentioned it. Because I do it unconsciously without thinking. But I’m checking the heat in the part. If it was hot I would cool it down with the coolant.

[@EdgePrecision]

No the end mill I roughed this part with was ground by a local tool grinder a long time ago.

[@lwilton]

I think you are defining "efficiency" wrong. Except for having to babysit the feed rate on the roughing passes on the turning, it was 100% efficient use of *your* time. You could go get something important done rather than watch a machine cook metal, and the part was ready when you needed it to be ready. And you didn't have to waste your time watching it. On a separate subject, can you sharpen that old worn endmill on your cutter grinder, or is it not worth doing?

[@matthewmarquette6778]

With that machine couldn't you mill down the holes close to demension and taper them out around the circumference to not have so much of a interrupted cut

[@EdgePrecision]

Yes that is possible. I have done that sort of thing in tougher material. For this one part I didn’t bother.

[@jimsvideos7201]

@@EdgePrecision Thank you, I was just about to ask that exact question.

[@TheWidgetWorks]

I've also just turn milled out the rings of material at the bolt holes, takes longer but is less risky in scarier materials for sure. For this I would have done exactly what peter did, little bit more baby sitting but for one part not worth the messing around programing it.

[@TheExtream]

on the holes you could mill a slot so the roughing tool had no interrupted cuts. but if this is just a one time job with low part numbers it dosent really matter i guess

[@EdgePrecision]

If I had a lot of this to do. I would set up a different turning tool with a large lead angle. lets say a CNMG 80 degree sticking straight in giving me a 40 degree lead angle. Than I would rough machine a large V groove that that tool could walk in and out of at the hole locations. With a feed and speed and depth of cut the tool could handle. Than come back and rough to that groove from the tail end and rough from the other side of that groove to the chucks end of the part. But for one part it isn't really worth all that.

when using the second chuck on the tail stuck you may have Oval shape after heave machining due to have only 3 point contact . i usually make a plug " stepped plug with a center hole in the back and hold it with the tail stuck . i never had any issue with that way . i want to know your opinion about that .

[@EdgePrecision]

If I was doing a number of parts I would make a plug. In this case the part didn’t require that precision. That said this little 6” chuck doesn’t have the power to destroy that heavy wall tube. A plug is better it gets the tail center up closer to the part.

Hi man

[@lancer2204]

There are, as they say, many ways to skin a cat. So, why not use up old tooling where you can? Sure, you could use CBN designed for interrupted cuts, but at what cost? You could use a helical ramping and rotation in the C axis to remove the sections with tabs left to reduce vibration, but then you have lots of tool wear at the tips and time. Then the time needed to remove the tabs and slug followed by clean up passes with a fresh tool.

A live centre is driven, a dead centre is not! It's a rotating centre when it has bearings in it!

[@EdgePrecision]

No a dead center doesn't ever rotate the work rotates on it's tip. This tailstocks quill has a spindle with bearings that rotates. In that spindle there is a #6 Morse taper that you mount, what would normally be considered a dead center. Were it not for the fact that it is mounted in a spindle in the tailstock's quill. That turns it into what is considered a live rotating center. In the machining world I'm aware of a center that's in a tailstock that can rotate and is supported by bearings is considered a live center. Weather it's in a CNC machine or a manual engine lathe. Go to any catalogue for machine tooling. Look in the index for live center. Go to that page what do you see? A driven spindle in the tailstock is a sub spindle.

[@MatthewTinker-au-pont-blanc]

@@EdgePrecision When turning between centres, the headstock centre is live because it's driven! In the tailstock, the dead centre is greased and a rotating centre has bearings or brushes to allow it to turn. It is commun usage to call a rotating centre live, but, it's not driving so it's not live!
