Must-Watch for Machinists! The Most Important Thing to Look at in Machining

This is the most important thing that I look at in CNC Machining and most of the top level guys in the industry do as well, but not many up-and-coming machinist even know about it.

[@josephcampise9950]

[@foghornleghorn2445]

Your shop is amazing. Clean, well lit and organized. A machinists dream.

[@DBADruid]

Looking at the formula because it is a multiplication. The only way to increase the "cubes" is by increasing the IPM or by using a better tool that has more woc or doc

[@paintballthieupwns]

And making sure your fixturing can handle the MRR - and maybe multiple parts to the spindle keeps spinning instead of stopping to be loaded all the time. You can think or MRR over a day.

[@chuychacon777]

excellent explanation Titan, going to the fundamentals so we can build strong from there, more vids like this! thanks

[@mnucad]

As all your videos, Thanks Titan. You are someone to follow as model success. We use KOR5 1/2" with MRR:32 in3/min and that means a lot of productivity. Thanks again.

[@karlomoharic3992]

The most important measure is TIME , because you charge your customers based on total time needed to make and inspect the product

[@TITANSofCNC]

MRR is based on the most cubes of material taken off in a certain amount of time…

[@Madkite]

Well by the description. The most time is spent in a normal job is removing the bulk of material. Thus for most jobs if you can remove it faster them thats where you makenup time. So MRR is the key number. While you may be able to finish faster using a mill with more flutes, there's probably not as much to be gained on that. And it's time will be dictated largely by the tolerance and finish spec. Everyone will have to meet that so its not going to be hugely different unless somebody is rubbish or telling pokies. There may be unusual jobs where this doesn't apply bit he's talking about your bread and butter. Would be interesting to see how this is applied to lathe work. Never see much cnc stuff on lathes. The skill is in knowing how hard you can push either the tool or the machine. My little cnc hobby mill only has 360w on the motor. But that's a lot on a 3mm end mill. The only difference is scale. So even it once you are in to small parts you are looking at how hard you can push the tools. I'm actally quite shocked by what 360w can do. OK it's not ripping of material like these beasts. But a 10mm end mill taking a 10mm deep by 0.5mm step at 600mm/min is way more than I expected. Its a really strong little mill, and I'm loving it. Feel like I'm doing the wrong job.

[@crazycooterMN]

Mr. Miyagi of machining right here I love it!

[@jonathanbatson6541]

There are many factors in the overall time used to make a part but MRR is a piece of the puzzle for sure. One thing to remember is that it's great to save ≈1h in machine time however if it just sits on a pallet that gain is lost. You have to take this drive of improving the process and apply it as whole to the entire company. With that said; I would like to see more about how you inspect these parts. As a metrologist a and CMM programmer i think talking about how you machine to hit the specs would be cool. I.E machining to the Datums ext.

[@jamesjensen6157]

I notice you guys climb mill with the end mill. You can get a lot more meat off if your not and not have your work get snatched out of your vise or chuck. Love your vids.

[@tattooedmillionair]

(coming from somebody that doesn't know you) Unless you use a down-cut em, I don't see the difference a piece getting pulled up from the vice. Also, do you know about how much more of a chip load an em will take (climb vs conventional)? To my knowledge, any chip load recommendations from the tool manufacturer are based on climb milling. I'd appreciate any feedback.

[@Greg-ms4kk]

Ok Titan Mrr is not the most important factor. I have been in this industry for 35 years. I manage a shop (small) and run 3 machines (one 4 axis and two 5 axis Mazaks) fixturing and programming is what brings in the dollars. We mainly run small lot Aerospace parts in all the materials you talk about. Killing it is about One and Done setups. I design complicated fixturing to complete a part in one setup. I dont care about MRR. I care about one setup for a part and ship it!

[@PlinkingLePew]

I'd argue it all is about equally important, however it all comes down to process reliability, doesn't matter how fast your going or how good your fixtures are, if your parts are taking inconsistent amounts of time your process isn't reliable. Whether it be becuase your going to fast and breaking tools, or your fixtures aren't as "idiot proof" as you'd hope. Tool paths can create unreliability as well.

[@Greg-ms4kk]

@@PlinkingLePew Your response doesn't even make sense! WTF? what if it is a casting! MRR? I dont think so..........

[@PlinkingLePew]

@@Greg-ms4kk did you even read my response? How doesn't it make sense? I'm not saying MRR is the most important thing. I'm saying process reliability is. Regardless if your using castings or starting from raw bar, if your process isn't reliable your parts will all be taking inconsistent amounts of time.

[@Greg-ms4kk]

@@PlinkingLePew Yes i read your response..... Your parts cant take an inconsistent amount of time. Toolpath is Toolpath. Every part you run is the same exact time. If you are breaking tools to slow that process down then your programming is off. And yes my fixtures are idiot proof..... Every single time....Perfection is my Mantra....

[@PlinkingLePew]

@@Greg-ms4kk first off I'm not speaking of you in particular. Second, your missing my point, for example If your going to fast and tool life isn't consistent then your parts machine times aren't consistent becuase your forced to change out tools....making the process unreliable. If you alter the program to reduce feed and make tool life more consistent, well guess what, you just made the process more reliable. So again. Process reliability is king.

[@TheCrjflyr]

It is as certain as death and taxes that someone in that shop is dying to stick a firecracker in that yodeling chipmunk and light the fuse!! LMAO!!

[@mehmettemel8725]

I've realised in my case excessive time spent to accurately quote a job is a bit of a waste of time when the cycle time is short and quantity is very low like 1 off 2off or just a few.US is a big market not like here in oz.

[@frank198011]

Thanks Titan.

[@dirtboy896]

So the greater the WOC and deeper the DOC combined with fastest feed rate for the tool/machine/material is what youre looking for. To remove a said volume of material as quickly as possible to leave time to start on the next job and make more $. Did I get it right?

[@christianbreu814]

So we have an Endmill in our Shop with nearly double the Mrr :) Kor5: 2.5mm x 50mm x 10000mm/min =1.250.000 mm³/min Our Tool: 7mm x 30mm x 11000mm/min = 2.310.000 mm³/min

[@PlinkingLePew]

Same material being cut? Can't really compare machining something like 4140 to say 718 inconel.

[@christianbreu814]

Yes, same material. Aluminum, maybe a little bit diffrent but not a lot.

[@AlexMageethefirst]

@@christianbreu814 shorter tools can go harder. it doesn't help much if the wall of your part is 50mm, you would need to come back for a second op with a longer tool increasing machining time. also there are other metrics at play, how long do your tools last? you can always push them harder, but if you're looking for a reliable stable process it's best to run them less than full throttle.

[@PlinkingLePew]

@@christianbreu814 what endmill? I use a gwstool alumigator ART for all my roughing, it's capable of doing some pretty serious MRR.

[@paintballthieupwns]

You need to compare a 7mm Kor5. No way to compare a much smaller tool to a bigger one.

[@TrPrecisionMachining]

good video titan

[@davidbarnett1631]

Love your videos man. I'm not in the cnc biz. But I love your additude and positivity.

[@angrydragonslayer]

I mean, i understand MRR and all that but i still hate plunging a custom internal cutter straight into the piece in the way the companies i have worked at do I just dont like the sound or the vibrations coming from it but it removes upward of 16kg of steel per minute on some machines I think 16.7 kg was on a makino mag 3 where we plunged a custom 8-stepped in-house cutter about 600 mm into a block of steel at ~1500 mm/min, hitting about 95 KW and putting the fear of god into all the workers nearby

[@rahimkassam9838]

How do you determine your max width and depth of cut for various materials? is that a spec of the bit?

[@AlexMageethefirst]

i can't speak for titan but i'm my shop depth of cut is always the flute length of the tool, width of cut is the maximum i can get away with before the tool starts deflecting or reaching full load on the spindle. whichever comes first.

[@rahimkassam9838]

Ah ok, that makes sense. Do you do test passes to check for deflection or how do you know when you’re reaching your max spindle load?

[@michaelfracasso454]

Not working with Titan, but I used to be a machinist. It really depends on the tool, the horsepower, and the job. For example, with a 6 flute tool it's usually better to put max speed in terms of ipm, and see after what's the width you can take. With a 3/4 flute I prefer to go full diameter and the push it to see how far we can go. So the differebce is excentially on the application. I prefer using a 6 flute mill, for the exterior roughing, for the ineterior, i use to use a 4 flute if it's someting big, and a 3 flute if it's someting smaller, because the second one can also drill very fast without using cirular interpolation, that slowes down the speed pretty much. The rest is all about the machine, so how far can you push it, and in bigger machine you can take bigger depth or width of cut, in smaller it's better to speed up in terms of rpm, go full speed in terms of ipm, and the take a little depth or width of cut, in stronger machine you can take bigger asportation. I'm from Italy so I don't know if my grammar is quite correct, but i hope this will help

[@brandons9138]

@@themattrixrevolution I was in the exact same position at my last shop. I'd get handed travelers that were printed 3 weeks ago, now the job is due in 4 days. Meanwhile all of the machines in my department are booked up with all of the other jobs that sat on somebodies desk (not mine) for 3 weeks before I ever saw them. Then management bitches about OT and late jobs. I was in a production meeting one time and the shops "president" asks why the shop schedule shows that over 1/3 of the jobs on the floor are late. He says "That can't be right." My supervisor steps up and says "Yeah that sounds about right" I have a stack of travelers with me at the time. I showed him the dates on them and what I have currently running in my department. His jaw hit the table. Not only was it more then 1/3 it was over 50% of the jobs were currently late. I had jobs that were due at the customer BEFORE I even had the traveler in my hands. It got to the point where I kept a spread sheet of the dates of when I was handed jobs and the dates the traveler was printed. It was that bad. To make matter worse less than 3 weeks after that meeting all of the supervisors and department leads get an email from the "president" saying that we needed to make sure our jobs were "on schedule" and to "keep OT in check". That was the last straw for me. To me it just showed that he had ZERO clue as to how to effectively manage a shop or how to actually fix the issues that made us constantly late. I got a job a t a better shop MUCH closer to home for a shit load more money with people that actually understand how to run a shop. Last I heard not only the "president", but the shop's GM had gotten shit canned for poor performance.

Great video. The answer to the kids who ask why do I need to learn geometry and math? Well, because the other guy who knows math can outbid you. I’m curious do you also take in the costs of the wasted material?
