Stringy Chips Wrapped Around Your Tools? Mark Has a Solution! - Haas Automation Tip of the Day 

These videos are very helpful. They played a part in me purchasing a brand new VF6 for our shop, our first ever non-mazak CNC. We love it, and i just incorporated the "E" value into a program I am running right now. My operator loves me right now. Thanks Mark.

This idea is brilliant...... Reversing the spindle direction in order to clear the chips out of the flutes! We all run into this problem, especially on soft aluminums or hard super alloys. This might even counteract chip welding problems.

couldnt help but chuckle at the reversing solution. sometimes with machines like this, you just expect to have to throw money at the problem for some other $5k ultra high pressure coolant pump deluxe 3000 add-on, while the solution could be so simple.

I've been a CNC machinist for 20 years. I seriously did not expect to learn something new today, but there it is. Birds nests are often a rookie mistake from underfeeding and I've usually found work arounds by feeding hard enough to break the chip and running the process up fast enough that pecking, broken chips, heavy chips and centrifugal force does the job but adding a spindle reversal like this on your control is a great idea. Well done.

I appreciate all these videos, keep the good stuff coming guys!

Always bright, clever, professional thoughts and approaches wrapped up in a first class presentation. Great work. Thumbs up!

Im no professional but i do own a Haas. I really appreciate these tips as i would otherwise never get exposed to "real" machinists in an industrial environment. Priceless for a home gamer like me.

Really enjoying these tips. Been in the trade 22 years now but still learning so much.

I used to do the reversed spindle, but later the spindle motor had issues because we werer working on thousands of holes drilling 33 thousand times later reversing the spindle, motor didnt really like it... Also, pecking isnt the best way out since it tends to overwear out the drill. We managed to settle all those issues by using higher feeds BUT also putting a stronger inside coolant system to cool off the drill during the process and to get those chips out (we drill deep holes)

I love watching these videos and then go back to work running a 1995 vf4 that doesn't have those features 😂. I ran into an issue where my boss programmed a drill cycle that not only built up the chips but also got the counter weight swinging momentum in the back of the machine. Those were interesting issues to fix.

Awesome tip! Thanks!

Thanks for this, it was super helpful while machining nylon.

Reducing rpm has always worked great for me and usually improves finish as well. Plus actually increases tool life since the tool is getting coolant.

Awesome tip. I've got a job in working on now that I have this chip problem with on a 5/8 end mill from plunging a counterbore. I'll be using this for sure.

I'm in the College studying CNC Machine Shop, but, I learn o lot with your page 👍👍 thanks!!! Keep doing good job & teaching!! Have a good one

Use Helix Bore! It's faster and you eliminate the chip problem before it starts. You also have better control over size since end mills cannot guide themselves accurately when plunging.

saw the title, and thought to myself "is he going to talk about reversing the drill and dwelling?" and then I laughed, I figured this out in a machining forum a few months back, saved my ass with some Delrin Jobs

I discovered this solution on my own a few years back, but it does have to be used with a dialed in chip load to get heavy enough chips to make it effective at all. Of course, there are a few more things that can be done with negligible time difference compared to an M04 and dwell, I would add a peck to that counter bore, or interpolate with a smaller endmill before adding wear on a machine.

As always great content from you guys.

amazing video Mark! I want to be your student. Cam you tech us how to properly calculate, Lahe feed, speed and depth of cut?

These tips are gold!

Information that I totally did not need to know but is still interesting to learn!

Hi Mark , how you doing I want to say thank you for your videos. I don’t understand the whole English because my first language Spanish but I’m really appreciate your videos. I follow you for a while and again thank you very much for that information God bless you. 👍 i’m always trying to do my best better than nothing.

Thank you for being you Mark... you've taught me a lot about the code.... i am a fan

Love this tip of the day series

Would you recommand doing this with a live tooling attachment on the lathe?

Man's a Genius

what a workshop, nice tip, thx for sharing it :)

You can also use the programmable coolant nozzle to walk the string down as you have spindle reverse

Improper speeds feed and improper machining techniques are usually the culprit as shown in the video. I rarely have a chip wrapping issue. Tubing mat is the biggest chipper for me. Most of our machines have through the tool coolant, that helps. Typical materials I machine are Stainless (303, 304, 316, 416) Alum, variety of steels.

Whot will affect the spindle resource? This drilling method will cause high spindle wear?

Curious how well this works with smaller tools. I have always managed this issue with speed, feed, and tool choice but sometimes it is tough to get clean drilling. Peck drilling is my last option because it is so slow.

Any tips for this but on a lathe? Usually boring bar and drills

So that's why that stuff happens? Now I know....good stuff. BTW this is a neat trick, and this channel is awesome.

On the first look very clever. BUT it will make the process longer and it will stress the spindle motor I guess.I usually go for feedrate or clever chip breaking. After all, the only operations in witch I might have some chip probs are threading and boring. But also in these operations there is nearly always a sweet spot, you only got to find it.

I'm about to finish school for machining. Already got my nims cert next is set up. These are great tips thank you

You can also add the reversal to your post processor.

Hi, Can you have optimized end mill feed & speed data for aluminum, M.S., S.S. etc How to get super fine finish with ball nose.

Can a G84 work the same if I don't have NextGen? Or reversing before while at the bottom of the hole will cause more problems?

Great video l will have to give it a try 👍

It would be great if this was an option in the NGC post processor! Is it?

Good tip thanks a lot

Great one!

Any tips on clearing chip wrap from a boring bar? Tried reversing doesn’t help

Will that work for tapping too?

Very good!

Thanks. Great idea.

I love these videos, but i have a question; does reversing spindle direction work for gundrills as well? I use solid carbide at a pretty speedy feed-rate but I still have issues with clumps of chips and I don't want to peck with the depth i'm cutting at

Could you use a slightly smaller endmill and helical interpolate the hole? Then you'll have small ships and not strings.

I notice on my TM-1P that the spindle load meter shows, for just an instant, 100%. Is the OK for the spindle? Otherwise this tip works great.

This works with the drill cycle, can we add this to a tap cycle as well? Specifically the G84

Nice tip also my problem.... thank you

Super helpfull. Tip: For tapping (in Aluminium), using thread milling instead.

does this also work on live lathe tooling? on NGC?

Wouldnt instanly reversing the tool shorten the life of the spindle quite alot?

Thanks Mark!

Perfect 👌 thanks for all teacher

Good Stuff!!!!

I would use an mo1 before the tool indexes so I could remove the stringy chips .

Does anyone know if there is something similar for Fanuc controls? Thanks!!!!

Ok, THAT is interesting! Thanks a lot! :D

I wonder if the Fusion 360 team could add this as an option to the post?

If we are tapping no. of holes, if we stop and reverse every time doesn't consume more power ? i.e accelerating, braking and reversing again to cutting direction.

Sir, possible means pls do doosan hmc machine problem

Do you have show me how set up mill and lathe

great solution

Can the E2000 be used with a G73 drilling cycle?

cant plunge with a true end mill on slot drill there's no cutting edge in the centre but nowadays a lot do soo

Hi... Dear Sir, Wonderful performance Thank you❤

Love this guy's

Yours tips are very helpful for me. But why is not there polish subtitles in newest videos?

Is there Cosmos Mitsubis conraller coad

im working on a hass 750ss, we added this E2000 on our post processor it was all great until our machine was getting some vibrations during machining and bettween tool changing some tools were falling. we contact support of haas on portugal and they correct that vibration and the tool change doing a downgrade on our machine software, all great again but when the machine reads the E2000 nowadays she dont assume the 2000 rotation and instead she goes until the max speed of spinde 15000 and until the spindle gets to that speed it adds a lot of time to the drilling. very lame from haas we are expecting a upgrade to software that corrects this and some other bugs since january or february. to the ones who have correct software on machine this e2000 is a beast in clearing chips, to the other ones like me just cry day and night

Super method sir chips removing

Now this is Awesome..

thanks mark

Can anyone tell me the latest version of software? a technician from Haas came to repair my Cnc because the battery was dead, he changed the battery and asked me that which software version I want him to install, the latest or that was installed before! before there was a software version of 2009 and now there is a version of 2011 is that a lastest version?

I tried this for a spiral tap but the chips are still caught in the grooves of the tool. Does anyone have any advice on reducing chip buildup on spiral taps? It's a 10-32 tap so using a thread mill is not possible for me. Thanks

Anyone know of a way of skipping the reverse of the spindle till the last hole on a G73 cycle? My R plane is low and won't spin the nest off till the last hole and I'm concerned I'm wasting cycle time.

Does anyone know if there is a way to program the spindle to reverse after each hole inside of Mastercam? We don't have Haas machines in our shop

awesome...!!!

sir we are facing same problem in turning center where chip is not getting broken and whirling around insert ,because of this in component we are getting burr mark mainly in finish operation , so we increased feed and corrected coolant ,used peck drilling but still we couldn't solve this problem. pls give us better solution if possible

Doesn't work in my HAAS VF5

Does this code work with any other cnc machine (Bridgeport hardinge v1000) or just haas?

Can this be applied to a tapping cycle? That would be awesome, if it can!

Greate!!! Tip!!

WOW , I feel dumb now lol , been machining on HAAS for 23 years . Time to try this , So I can get rid of that damn M00 , BEEPER!!! remove chip! Thanks

Great advice if you manually program the GCode, but we cannot figure out how to do this if you build your GCode from Fusion as we do! Do anyone know?

Spindle reversal is a nice trick, but it must make a lot of additional electrical consumption, no?

pls explane the g10 for 50 piec

it will affect the machine spindle?

I only get a bird's nest on my taps and I doubt that's gonna spin it off. plus I'm so used to it that when the tap is about to break, it doesnt collect chips any longer.

that works with mill machines, what about lathe machines?

Drill is big cant increase the. Speed and cant manually reverse the rotation its time taken though we need production

Thanks, now I can machine my string cheese more efficiently.

Come on guys, just stick the handle of your chip brush on the cutter while it's spinning. ;)

is it a company or just training centre????

原来可以这样操作…受教

am i the only one stunned by his shiny head in the beginning of the video? his head is more shiny than the floor he is standing on

👍
