Tom's Tips & Tricks #3 - Plunge Milling

[@firetie28]

Some of the best advice I have recieved yet. I was a mechanic by trade, fell in love with the sea and worked on tugs for a while. Now, I am shoreside with an office job. I say all this to say, I am not a machinist, not even close. Wasn't even a hobbyist till 2 weeks ago. In 2 weeks I made a few mistakes. Your video here straightened me up enough to actually mill the needed components. I am building a sawmill from the ground up. I needed to machine 2 bearing guides. I humbly thank you for sharing what you know 🙏 looking forward to watching your other vids!

[@dennyskerb4992]

Hey Tom, great to see your videos again. Hope all is well. You'll always have an audience because of your knowledge and willingness to share.

[@TomsTechniques]

Thanks Denny. All is very well. The company I work for sold last month, which enabled me to retire, and Thursday was my last day. It's been a stressful month, with lots of financial stuff and tying up of loose ends, but it's all good. Monday morning it'll all sink in when I don't have to get up and go to work. :) Tom

[@mamoshimiloni9559]

I have been following you for many years now and I have learned alot from you, and I am Grateful. I wish you the best of Luck in what ever you do and lots of Good health and happiness. Thank you for making these videos and sorry my english :)

[@1DIYGuy]

you showed this awhile back. It has changed the way I mill. The big plus for me is the end of the end mill dulls not the side flutes easier to sharpen and the end mill can be kept true to diameter longer Thanks again for a great tip.

[@TheEpistemicOne]

That Hardinge Lathe is so sweet! Had one at my previous job and loved working on it. I recently purchased a CNC mill to start my own shop in addition to designing and marketing my own products, so your comments at the beginning are definitely inspiring.

[@TomsTechniques]

Thanks Dennis. I'm considering a Haas Mini Mill to play with after retirement. I had a Hurco CNC mill at my disposal on my last job and it hurt bad to leave it behind. Tom

[@TheEpistemicOne]

I bought a Haas Mini Mill and am glad I did. Great little machine.

[@TomsTechniques]

Sounds like you need to start saving for a Hardinge. :)

[@stephenmcdaniel1941]

Thanks Tom. Glad you're back. I never thought of this technique until I saw you use it on the carriage stop body, and since, have used it a lot. It's faster, and it's easier to sharpen the end of the mills than the flutes. Makes 'em last longer.

[@TomsTechniques]

Yes, that is a plus I forgot to mention. Thanks for watching. Tom

[@humblyright]

Hi Tom, I just found your channel and really enjoy your techniques and processes. I’ve learned quite a bit from you and hopefully by the time I get through your library of videos you’ll be settled into that new shop you’re building in MI. Wishing you a safe and successful move & looking forward to more videos in the near future.

[@TomsTechniques]

Moving at this stage of my life is quite a challenge, especially when there is a machine shop involved. We are pretty much into the house, although I am still working on the kitchen remodel and some built-ins. The shop is pretty much complete and I have been moving in machinery. It's located in the U.P., so everything has to be trailered up from midstate. So far, the mill and lathe are safely in their new homes. The propane delivery is scheduled and I'm in the process of installing a condensing boiler for the radiant heat. It'll be nice to have heat before the U.P. winter moves in. I wanted to have the well put in too, but it looks like that's gonna have to wait for spring. I'm definitely looking forward to getting the shop operational again and start making more videos.

Looking at that part you made I'd imagine there was some warping after all that material was removed. I like your comment about the stress relieved weldment, that's the first thing I thought of when I saw what you were making.

[@TomsTechniques]

Another useful video, again thank you. Also, some guys like to use WD 40 on aluminum. Do you recommend it?

[@TomsTechniques]

Thanks. WD-40 works well as a tapping fluid on non-ferrous metals, but it smokes too much to use as a cutting fluid on anything but very light cuts.

[@ProfessorKhamke]

I use this to crank out mill stop bases whenever I need more. A 33/64 End Mill and ~.100 stepover between plunges will push out a slot almost as quickly than I can think about it!

[@holdensherard4664]

I can't imagine buying a hardinge lathe new. The ones I have seen were made before the second world war, still ran like brand new, and were still worth a fortune! I would never be able to justify buying one. Very nice.

[@TomsTechniques]

Machines like that are excellent investments if you have the ability to put them to work. People spend that kind of money on cars all the time and think nothing of it. Machines like the Hardinge hold their value AND generate income. It's a win win. Thanks for watching. Tom

[@santopezzotti730]

Good morning TOM I’m the 71-year-old newbie and I’m finishing up setting up my shop at home mainly to do hobby work. I do have a LeBlond leave and a Bridgeport along with the surface grinder. I was wondering what your opinion is in reference to should I prepare my shop for the process of using coolant on the Lathe the Bridgeport Milling Machine. I’d be really interested in your opinion. I guess the question boils down to why do you need coolant I understand you use cord to keep things cool but if you’re a hobby shop and time is not actually the most important thing do you still need coolant

[@TomsTechniques]

Coolant is more if a nuissance in a home shop than a help. You can't just mix up a tank and forget about it, it must be maintained and the tanks kept clean. It also tends to rust machinery when only used on occasion. If you need it at all, just use a spray bottle and mist it on the cutter as needed.

[@santopezzotti730]

[@aaronholstrom1971]

Thanks Tom! Another great video.

[@jaysilverheals4445]

He uses it for roughing out such as can be done in slots by stepping over however with a cnc plunge milling is of super importance for many reasons especially angled walls. It should almost always be done cut down only and rapid back up and stepover for a few reasons. It produces perfect accurate angle walls and tapers where as going around and around--does not. The benefits are many and is analagous to making a lathe cut--the cutter cuts on the end but produces the finished surface as the tangency of the radius of the insert moves along--just like a lathe. Another huge benefit is truly astonishing roughing rates because you can step over 1/4 inch and be hacking off .100 deep to rough! (that by the way shows why you must plunge cut only ONE WAY--DOWN) and rapid back up just like he did in the video. yet another benefit visualize a 3/4 insert cutter producing a million machine taper inside or even a straight wall or big round bore?--note that since inside the cutter can step over .030 OR MORE each time finishing the taper perfectly in a couple minutes.. if you do the match the cusp is almost nothing even with massive stepovers. Yes it works and is done daily in industry. Another benefit is that the insert and cutter hardly care if the material is aluminum or hardened steel.. however going around and around stepping down it certainly does--THE CUTTER WILL PUSH AWAY A HUGE AMOUNT AND GO DULL.. you will not even reach the bottom.. Plunge milling in hardened h-13 is how we cut hewlett packard printer body molds and other things. Also you can plunge cut straight deep walls even in hardened steel and the walls will be perfect and straight--but be aware you have to relieve the side of the insert so that only a small land is hitting you cannot have the insert scrubbing against the walls. Anyone interested I just created a FB group--shapers and zlinear plunge milling techniques and tools. If you type in all one word SHAPERINFO it also will come up It is also based upon the shaper attachment that goes on the back of bridgeports..

[@ShawnD1027]

This is quite timely for me, as I'm about to mill some vehicle steering arms out of billet steel and was thinking about how to go about initial rough cutting of the parts from the billet. Since my mill is a hobby mill (Taig), I was concerned about doing it in an efficient manner.

[@douglasbattjes3991]

Again Tom, great video, do you have any videos on setting a point on a new part using a DRO and then setting the drill points in the SDM ? Really impressed with your work shop.

[@TomsTechniques]

Thanks, Doug. The reference point on a part is set using an edge finder, or an indicator for a hole. Not sure what you mean by SDM. Unfortunately, that shop is no longer. We moved and everything went into storage. I have built a new shop and am getting it set up, but it's a slow process. I hope to be operational again in the coming year.

[@RGSABloke]

Hi Tom, I don't have a mill but I recently got a compound table for my drill press and these techniques help with the overall ergonomics of using workshop machinery. Any thanks for sharing. Kindest regards. Joe.

[@israelmartinez2027]

Same speeds and feeds as regular depth cut pocketing? Or do you calculate it as a hss or carbide drill with the endmill diameter being used? Thank you

[@TomsTechniques]

Same rpm as you would normally mill at, dependent on the diameter of the end mill.

[@davidaarons2488]

Hey Tom, nice job. Having watched you before I have used your method and works great, I have one question is there a way to do this and mill a curve or angle with a manual mill? Or would you plot it out with dro. I am just a hobby machinist and make small parts for my radio controlled cars. God Bless Ya Dave

[@TomsTechniques]

Absolutely. For curves, you need to mount the part on a rotary table centered up on the axis of rotation for whatever curve you want to machine. For angled cuts you would either rotate the vise, or clamp the part to the table at the required angle. Tom

[@JonDingle]

Great videos and channel young man!

[@CJ-ty8sv]

Just out of curiosity, if you are starting with a solid chunk and as you said, couldn't band-saw off a large portion of excess material, why not have the first opp be a drill opp and drill all the way through the full thickness to drop out the entire center slugs from the solid full raw stock material? Basically just like your plunge cut opp but with a drill right from the start (full raw material thickness). It appears that you machined the opposite side (side down on parallel's) before doing the thru pocket. This to me seems like you would have spent a excessive amount of time milling off all that material that would have been removed by just drilling the complete through pocket as the first opp. Then would have only been left with the narrow area of material to hog off.

[@TomsTechniques]

Bandsawing as much material out as possible is always faster than milling. As I mentioned though, my saw is a little small for that so I opted to just mill it complete. Milling deep with an endmill is slower than keeping the cuts shallow due to chip removal and heat generation. That is why I opted to save the framing operation for last. Tom

[@samahdicox3120]

Chris I thought the same thing, first op I chain drilling the full thickness before you mill anything , also was a bit poor on the work holding in the vice , Soon as the centre piece is removed the pocket will close up as the two ribs are outside the vice jaws, the pocket will not be square and the clamping force is reduced so the piece could lift out , 👍

[@TheCommo81]

Just curious you mentioned heat, why not show down your speed a little bit? I found slower speeds are better. I clear chips better at slower speeds without the need to plunge cut.

[@TomsTechniques]

Running an endmill outside of its recommended rpm is asking for trouble. Too high will burn it up, and too low will increase the chance of breakage, due to a higher chip load. If you are having trouble clearing chips, your best bet is to decrease the depth of cut, and increase the feed rate. Or, with deep pockets, use plunge cutting.

for plunge milling (aluminum) 2 flute or 3 flute best option?

[@TomsTechniques]

Fewer flutes are less apt to clog up in soft metals.

@@TomsTechniques thnx

[@emanekaf4107]

would that be the same as drilling it out?

You could drill it out, but this requires less cleanup afterwards and doesn't require a tool change.

[@TomsTechniques]

A roughing end mill is designed to side mill. No need to use this technique for them. Tom

[@Mirandorl]

Hi! I am a little confused. If I understand correctly, climb milling has to do with moving the part against the direction of the cutters rotation. I can understand that ok when the cutter and part are moving in the same plane, say the XY plane. You indicated that the plunge milling should be done as a climb, but I don't see where the 'climb' comes in as the direction of travel of the cutter is in the Z direction, and at 90 degrees (i.e. downwards) to the cutters rotation. What am I missing? Cheers!

[@poozandweeez]

climb milling is where you cut in the same direction the cutter is turning, so the cutter almost drives along the cut like a wheel on a car, conventional is going against the rotation of the cutter, climbing can be dangerous on less rigid machines as the tool an grab the work and dig in, resulting in broken cutters, chatter, and or poor finishes, in a rigid set up, climb milling is preferable, less load on cutter, extended tool life, and better finishes and swarf evacuation

[@Mirandorl]

I get that part, but when you are plunging the cutter *down and through the part*, like a drill as in the video, the movement is neither with nor against the cut. Its at 90 degrees to it. I thought maybe he meant the finishing passes, but there he both climbs and down mills.

[@TomsTechniques]

The first cut when plunge milling will be neither climb nor conventional milling, but after that, the direction the cutter is moved before the next plunge will determine whether it is a climb cut or conventional cut. A climb cut will push the cutter away from the work and a conventional cut will pull it in. Tom

[@Mirandorl]

Hi Tom, thank you for replying! Thats the part where I am confused. I am a newish machinist, and my limited understanding of climb / conventional milling has to do with both the part and the cutter moving at the same time. For example if your cutter goes clockwise and, looking from above, your part is moving across its top at the 12 o clock position, when the part moves to the right then that is climb milling (with the rotation), and when to the left it will be conventional milling (against the rotation). In the video your move and cut are separate, moving the part along, and then with the part stationary, taking the cut. As there is no relative motion horizontally, how do you determine climb or conventional? I see what you are saying in the video that the cutter will want to push or pull away from your edge. Is this also defined as climb / conventional, even when the part itself is not moving?

[@TomsTechniques]

There has to be movement between the cutter and work to create a climb or conventional milling scenario. When plunge milling, that movement is on the Z axis. Tom

Great video Tom, I have to make a series of holes (24) on 3/16 plate, with ID of 1.25". It does not have to be precise , just the spacing in between. Using a vertical mill, what cutting tool would you use for the job?

[@TomsTechniques]

I would start by first drilling them as large as possible with drills and/or end mills, then switch to a boring head and step them up to size. If you don't have a boring head and the diameter is not that critical a small fly cutter can be used. Lay the holes out with a divider first and remove as much metal as possible with an end mill, then take them to size with the fly cutter set to the final diameter.

Tom, I don’t have a mill or a lathe but i do have a floor standing drill press. Would it be possible tp plunge cut with my drill press?

[@TomsTechniques]

Drill presses don't have the rigidity required for milling, or a method of safely holding an end mill. What will likely happen is it will chatter like hell and then the chuck will pop off the taper on the spindle and ruin your day. Tom

[@andrewkline]

Hey Tom, appreciate your work! Could you elaborate more on how one gets "outside work" or "bidding on jobs"? I hear these terms tossed about a lot, but i missed the memo where they told you where to go to get these jobs. Call me ignorant, but i've always been interested in doing side work, just never figured out where or how to find it - aside from beating down doors and the rest of the old-school hard marketing methods.

[@TomsTechniques]

Hi Andrew, I was lucky to have had some connections who opened a few doors for me. Most of the jobs I landed were for designing fixtures or attachments for machines and I was unique because I could do the design as well as build the devices. Once I delivered a few jobs, I then got more work by word of mouth. Generating contacts is always more productive than beating down door (with everyone else). Tom

That overhead heater must be some hot to stand so close to!

[@219garry]

I built prototype injection molds for 25 yrs. I wouldn't recommend clamping a part where you are taking out the center wider than your vise jaws. There's a chance when you take it out of the vise the center will bow and the pocket could actually flex out larger than you wanted. It might only be a couple thou but that's still bad if you have to be dead on.

[@TomsTechniques]

Yes that could be an issue as the part gets longer relative to the vise jaws. In this case, the purpose of the frame cut was to simply lighten the part, so a any bow would has been little consequence.

Tom I miss your videos. Hope all is well.

[@TomsTechniques]

Things are going very well on my first year of retirement. I'm currently building a 40 x 70 shop/toy box in Michigan's Upper Peninsula, so have been keeping very busy. I'll post a progress report one of these days once I get it all enclosed. Tom

thanks for sharing good tip

[@georgiusrisang427]

Hope you make another video on milling with different material, maybe ST 60 or more hard, because allumunium is too soft

[@TomsTechniques]

The technique is the same regardless of the material. Just adjust the rpm to suit. Tom

[@RobbyNowell]

Thanks for the tip!

[@jbijnens]

Great video.

[@campparsonssundayschool7844]

This is common practice for milling out pockets in injection mold making.

Those finish passes your climb cutting I would probably go in CW

[@TomsTechniques]

If you watch my video on climb milling vs. conventional milling, you will understand why climb milling produces a better surface finish than conventional milling. Tom

[@200xcBruce]

Saw that video thanks good technique all my years machining was never using the climb as a final cut. And could have.

[@MegaLifeChanging]

And using this method in a CNC mill really goes fast

Hey Tom, hope all is well! Whats the odds of a video soon or ever? lol

[@TomsTechniques]

I had planned to start them up again, but life threw me a hell of a curve ball and took my youngest son. Not sure what the future will bring right now. Tom

All is well. I'm just figuring out this new retirement lifestyle and so far, I've been busier than when I was working. :) I'm told that will change, and when it happens, I'll start cranking out some new videos. Tom
