Grip Stock - How to Access 100% of your Part Perimeter

In this video, I'll show a machining technique using 'grip stock'. This allows for 100% access to the perimeter of your part and may increase productivity and access to your features. Take a look.

[@mikepaul3959]

Joe, you are a great instructor. Your videos are clear and informative. Thank you.

[@arsanzic8592]

Without people like you YT would be a waste of time. Thanks for passing your knowledge and skills on, very helpful.

[@charlescompton4495]

Can't afford the machine but love the technology. Also, really like the video and teaching of the operation. Thanks from a retired old bricklayer who likes the machine trades, too! Greg

[@ChrisB257]

More inspired advice Joe - you have over time come up with masses of great stuff - big thanks as always. Machining was fascinating to watch.

[@DriveCrash]

Thank for the videos! I've been thrown into the world of CNC programming and have used the information I learned from your videos to dictate setups and part holding when I ran out of ideas. Thanks so much!

[@joepie221]

Good to hear. Make sure you watch the next video I post about the 'Dogbone' technique.

[@jonterrance6884]

Joe, Thanks for another amazing video. I can't begin to tell you how much I learned from this one. Wish I'd seen it a year ago.

[@glenlynch9765]

Good job Joe, enjoying your work and presentation.

[@southtoledobendla]

Enjoyed watching you make these, nothing like a up close view....Thanks

[@Birender100]

Sir, "AWESOME", what great way to handle the situation. Excellent. I wish you great success in your future endeavours. Thanks for the Video.

[@buildmotion1426]

As I’ve come to enjoy, high quality machining Joe. Back in the day we would turn all the excess chunks into chips to keep from breaking endmills. Also, we had the luxury of a vacuum table. We could slap a big olé plate down, and machine to .01 from breaking though. 2nd and 3rd ops identical to you. Welcome back, love your content.

[@joepie221]

Thank you

[@TroubledTimes2024]

Joe you are incredible, biggest problem is remembering your advice when it's needed, I'll have to go over them all at some point there is so much valuable advice :) Thank you!

[@joepie221]

Thank you.

[@armdaMan]

Hello there Cap'n Good to have U back and looking like a handsome Man !!! Always a pleasure to watch Your videos, even if we don't have the exemplary equipment. However, we are sure the principles could be applied in our "Home/Hobby Shops". Ideas aplenty. And again, "rinse n repeat", thanks for showing and sharing. Much appreciated ATB aRM

[@yopappy891]

Joe, you make it look easy. Great Job, keep them coming.

[@donjones7232]

Hey Joe, Welcome back and great video. One suggestion for the last operation. Instead of pecking the counter bore with a 3/8 cutter. Go back in with the 5/16 and helical ramp to final z depth. You will not have bird nesting and no worries on marring the finished surfaces. Saves on tooling cost and set up as well. Win-Win.

[@joepie221]

Thanks, I'll try that.

[@mxpimp47]

I do that all the time on low quantities. But if it’s a higher quantity I go ahead and drill to save some time compared to helical boring the holes. Good advice for some who may overlook saving on tooling cost.

[@DigiConSoo]

Great tip! That “lying to the register about tool diameter” thing has bitten me in the shorts a couple of times. Gotta remember to “tell it the truth” before I pick the tool for some other op. Knowing myself, I just write a new toolpath.most of the time. But it has come in handy as a back pocket technique once in a while. Love the videos!! Brent

[@joepie221]

Thanks Brent. Just don't tell the register its smaller!

[@keithjones8070]

Hello Joe, I think your videos are excellent. I thank you for sharing your knowledge with us, it helps us all in many ways. Kind regards, Keith, Perth Australia

[@Tkdmaster1991]

Great video as always! Just finished my machining course at my clocal college, and we were taught this method very early on.

[@charrontheboatman]

Very Nice work Joe!!! Hope business is good and keeps you fed and happy.

[@chrisd-gd6no]

another awesome vid Joe, I have learned a great deal from you -- many thanks from a Canadian Millwright!!

[@tobydulanski9480]

I’ve tried explaining this to places and they are more concerned about wasting 50 cents per part than the time savings that cost ten to twenty times as much with extra operations. The bean counters do not understand and continue to be penny smart dollar ignorant. It’s good to see places like yours being practical and reasonable. Thanks Joe!!! 👍👍👍👍👍🙏🙏🙏🙏🙏

[@joepie221]

Even radius features or large backside chamfers can be used as the grip stock region. Upside is, you can always recycle the excess material you mill away to recover some of your investment.

[@nonlinear68]

Currently studying to be a machinist, your videos are instrumental in getting me far in front of the curve.

[@joepie221]

Outstanding. Feel free to ask a question if you need to.

[@billflanagan5070]

Hey Joe, love the series. I appreciate when an experienced hand shows a method I have not previously experienced (such as the arbor for boring a stack of shims!). A couple of observations based on my loooong learning curve making thousands of the same few aluminum parts on a 1991 Haas VF3 (approximately the same spindle speed and IPM limitations you probably deal with). 1. Try using a stub parabolic for short holes like the "half hole". No center drill, no peck, and feeds in the 30-40 ipm range make short work and no tool changes. Especially good for jobs with lots of tapping, and I have become a form tap convert for almost all jobs. I can get over 1000 accurate 1/4-20 tapped holes in 6061 before I even need to START worrying about the drill. Prices on parabolics have also become quite reasonable with more manufacturers making them. 2. It looked like you used G98 for your canned cycles on the first op (i.e. G83 G98 R.1 Z-.5 Q.15 F18.), but may have forgotten on the third. I know, I know, I'm nitpicking, but it's always a time saver when you can eliminate that hop between R levels at the start of the cycle with multiple fixtures. 3. Have you tried tiny pecks (like .010-.015) and aggressive feed (40-50 ipm) in G73 to eliminate the rat's nest and maintain cosmetic surface finish when counterboring? This is also where the 3 Flute EMs that some guys are harping on can boost your feed rates. Since they are basically purpose-designed for aluminum, the coatings and chip breaking/evacuation are optimized for this type of work. Looking forward to more great vids!

[@joepie221]

Thanks for the tips.

[@skeeterweazel]

Another great video, thx. In the future, please leave descriptions on screen longer for us slow readers. Thx. Marth

We hope to serve dog bones before turkey day. Stay tuned.

[@beachcomberbob3496]

Glad to see you back. I know a lot of, let's say 'frugal', machinists will be screaming at the wasted material. But, as you said, if price per part is your major criterion, time versus material is a 'no-brainer'. I would imagine, in a commercial situation, you have scrap bins for recycling? Do you get any money for your scrap? If so, waste isn't really waste. Thanks for your wisdom, as always.

Done a lot of things on my bucket list. (Run my own business for 30 years)-. And that I, between 50- 64 years old, have a copyrighted song, completely restored an antique Jeep from the ground up and showed it in a magazine (Bolt by bolt), built a 1/2 scale real stagecoach, bought and drove a motorcycle for 2 years, Hiked part of the Appalachian trail, did 5 cruises, made fine furniture, learned finger picking guitar (Chet Atkins style) instead of just using a pick, recorded my music, playing guitar, drums, piano, bass and vocal, scuba dived, traveled 38 states, and now, it is strange but I had the need to know how to turn a shaft that would just press fit into a bore, which led me to love machining and it's precise engineering. And I love math. I can honestly say, you have provided and much clearer and easier way to understand the ins and outs of machining, and made my bucket list easier to complete: Thanks!!! I didn't list them all and I bet that was the longest sentence ever written- Another check off the ole bucket list!

[@paulmurphy612]

Nice. New vocabulary for me, "gripstock." Love my new word! :-)

[@davemanley8700]

Nice job Joe. That looks and sounds like a Fadal , I ran some aluminum 6 cylinder intake manifolds 3 ops with a horizontal rotary table about 10,000 parts. Aluminum is wonderful to work with. I retired 2 years ago as a tool maker/ fixture builder after 45 years in the trade. I've machined parts weighing 8,000 lbs. to parts the size of your small finger nail. I love your videos, you do a great job of explaining things with safety in mind, I've seen some people do some pretty stupid things over the years Like to see more of your shop thought. How bout a tour?

I've been very busy lately, but tried to collect some good video along the way. I have 2 more in the cue right now. Stay tuned. Good to be back.

[@Cinnabuns2009]

I don't know what the RPM limitations are on that particular machine but a Fraisa AXFP 1/2" or 3/8" 3 flute rougher you could run your 3 pass roughing in a single depth cut profile 1 time around the part at 30% higher feed (3 flute) saving you 2 passes on 2 parts per cycle and in Aluminum they last forever, I've been using a 1/2" AXFP for 2 years and its still fine. Still plenty of time to band saw out the chunks. That's a great tip btw. Its nice that you're doing something during the cycle and the cycle time is shorter. More parts in less time. Standard operation at our shop as well.

[@joepie221]

Great comment. Thank you.

[@billbubnis3128]

We use a product called crystal bond for small parts. Its some kind of an industrial wax than "glues" the part to a substrate in place during machining processes. There are a few variants of the product. Some can be removed with water some with acetone. Works well for us.

[@joepie221]

I'll have to check that out.

[@terryallen3550]

Beautiful part brother, love the shine on machine finished alloy. Had a brain storm, what if you made two expanding clamps with thumb screws or something that are the reverse of that first pass that have strategically positioned cuts for the clamping movement and sit shy of the machining to delete the band saw process. Just a thought. Thanks for the lesson so much and best of luck too you :-)

[@mrfrog3350]

Very cool vid Joe. We missed you Bud. I usually only grow a beard for the hockey playoffs!

[@sblack48]

Awesome finish!

[@joepie221]

Thanks, the customer requested a tumbled finish. I told him to wait for the machine finish before he decided. They shipped just as shown. Good call.

[@PaulSteMarie]

Interesting. I've never had much success using cutter compensation to generate a tool path from the part outline. The control would get confused at times and shoot off in odd directions. When I looked at the math I realized that it requires multiple lines of g code to figure out what direction to offset the cutter. As far as work holding goes, this part is a poster child for superglue to a fixture plate. NYCCNC has done a ton of videos on that. If I could get away with it, I'd use holding tabs and probably clamp the stock directly to the table with some sacrificial material under it. The only problem with that occurs if you need to flip the part and do 2nd side ops. It's very hard to get correct alignment after the flip unless you drill a through hole as a position reference, machine the rough stock to exact width, or touch off on the front edge after the flip instead of the fixed jaw. Beautiful finish on that part.

[@joepie221]

Super glue can let go under heat and pressure and is not very efficient of a production run. One piece its OK, but for dozens, the cleanup between parts is just not cost effective.

[@vbidou17]

Merci Joe ! It's a very usefull trick !

[@jrnbatalden4685]

Joe, you should look into the Witte Vacmat system or similar products. I run brackets and parts like this out of aluminum plate all the time, leaving 0.2mm of the plate so the cutter doesn't go all the way through. Out of the machine comes 20-30 parts that are connected by thin foil that you just break apart by hand. Subsequent operations I do much like you do with soft jaws etc.

[@amphib0410]

Good looking parts!

[@TheVicOlive]

Hey Joe, superb videos, you've a lot of experience to share! Question... is there a reason why you wouldn't have drilled the vertical holes as the first operation when the part is very stable as a rectangular blank?

[@MrJugsstein]

Hi Joe Nice one thanks.

[@smallcnclathes]

That was impressive!

[@tj9382]

Very nice thank you 👌

[@CalvinEdmonson]

You have an edge on me Joe but we think alike. Good work here.

[@Cthowell91]

why not run an adaptive pocket/profile and use HSM to compensate for a little extra feed time?

[@charleskelley1672]

Again and interesting video. The one thing that would concern me is when you are cutting out the blank you are running the mill and the bandsaw at the same time. The problem is that in a production type mode I would not allow someone to have their fingers this close to the blade. A piece of 3/4 pine notched out removes the fingers from the immediate area. I'm not sure that the amount of time running back and forth and the actual time that it would take to cut all the parts at once would be that great. I like to focus on one operation at a time when my fingers are involved. You only get one set. Nice video. Charles, Boston

[@joepie221]

In a true high volume production environment, I'd have turned the large chunks to chips and not hit the bandsaw.

[@jimmymymtv2254]

good stuff Joe,

[@ceschimusinagens449]

Parabens Joe.

[@TimCBuilders]

your whiteboard drawing are great

[@ogenmatic]

Taking a chamfer cut around the perimeter before you finish mill the perimeter & the face will ensure that you don’t have a micro-burr that effects the dimensions since any micro-burr would be along the 45 degree angled face of the chamfer.

[@joepie221]

Or it could just re-orient that micro burr to a vertical position.

[@louisshambarger2230]

Have a trigger guard made by a cranky old machinist/gunsmith. He did it in an old worn out Bridgeport. He called it profile milling. He could do beautiful work when he wanted too. Won’t work on guns anymore.

[@CatNolara]

Have you heard of the superglue and masking tape trick? John from NYCCNC really likes it and it allows him to machine a part from all sides, without anny grip stock. Also, it would propably be a good idea to have multiple setups in the same machine. One for the front side, one for the backside and one for the holes. Machine everything in one program and then just shuffle the parts to the next station, with one new stock piece in and one finished part out.

[@martybadboy]

Superglue and masking tape is for one off / prototype work. It's not useful in a professional, production environment.

[@kdtool9437]

That is a Mickey Mouse set up that hacks use😂 you think ford, GM, or MTD would ever use superglue and tape on their production lines, absolutely not.

[@larryschweitzer1007]

[@MrCrispinEnterprises]

Great video as always. Excess material and soft jaws is always good for strange profiles. One question - How did you set your datum in the X axis on the third Op when drilling / counter boring the last two holes? I couldn't see and vertical faces to features from.

[@emmajacobs5575]

It looked to me like there was a small vertical face at the end of the sloping shoulders of the part

[@pierresgarage2687]

Nice work for a CNC setup, that same part would be very time comsuming on a manual setup situation... ;) Well done...!!!

[@joepie221]

Thanks Pierre, good to hear from you. This would be a good rotary table job, but higher quantities would certainly hurt.

[@pierresgarage2687]

On manual setup jobs 2 is normally a production, one for practice and correct mistakes and the second one for the customer or for use... lol

[@joepie221]

That actually made me laugh out loud. Good one.

[@jimsvideos7201]

John @ NYC CNC pointed out a feature in Fusion to leave only small tabs holding remnants onto the part; might be useful to someone.

[@davidgrube849]

great! I’d like to see you do a video, doing a project like this, using a rotary table.

[@joepie221]

Since you are a subscriber, I'll do it.

[@jimwilfong8380]

Great stuff, I'm learning a lot from your vids! As a rookie I've yet to use soft jaws and was wondering about the amount of soft jaw "overhang" on the vice. The overhang appears to be several inches. Is this for alignment, or stability, or?

[@joepie221]

My jaws on this one are actually 2" x 2" x 6" long. The material chosen was driven by the depth of the part profile. The movable jaw was left at 2" in case I wanted to machine in a relief and add a radial feature to it to get down inside the part opening.

[@ellieprice3396]

Greetings from N.C. and thanks for another beautiful job. I learned a lot of good stuff about cutter rotation, speeds and clamping. What was this material, 6061T6 or steel, don't remember you saying.

[@joepie221]

[@davidwootton683]

Very nice videos, I take it that you are using 1 thousandth = 0.001 International Inches. 1.000 = 1 International Inch. I work with both systems, Metric and Imperial. A lot of the older machines out here are Imperial. Many thanks and greetings from Africa.

[@joepie221]

I am. Any metrics get converted anyway.

[@davidwootton683]

Thanks for your kind reply. Did you know that the USA is already metric, but they convert back to Imperial for usage by the general population. See Metric Conversion Act of 1975. As you know there is a lot of back and forth over this usage. Many thanks and best regards David.

[@trackie1957]

Check out "Measuring America" by Aldo Linklater. Fascinating story of how the country was surveyed and its impact on our history. In it you will find that Thomas Jefferson almost succeeded in getting us to be the first country to use decimal measurements - before France!

[@vmc7505]

I use this method frequently ,but use talon grip jaws for the 1st op. You can get pretty aggressive holding in talon grips. The only downside is barstock with rounded edges doesn't work so well. But since a majority of my mill work is aluminum or plastic I saw my blanks from plate on a tablesaw which I believe is a greatly overlooked tool for a machine shop. With the right blade aluminum cuts as easy as wood.

[@joepie221]

I have a Delta chopsaw with a carbide tipped blade for my aluminum bar stock. I sails through that material. Makes a mess, but its fast.

[@mcskifter]

How do you like your Talons overall? Is the accessory and overhead cost worthwhile? I'm debating selling a version of a rough stock holding jaw I developed for myself. Cheap inserts, about 0.014" of bite per jaw so even gripping saw cuts or uneven stock is no problem. I've been using them in a 4 axis machine and running some pretty big drills from the sides. The only comparable jaws I've seen have extremely expensive inserts, whereas mine are pennies and available everywhere (not a great profit strategy).

[@vmc7505]

NoReallyName I like the talon grips alot. Wish I had got them years ago. They are expensive for what they are but easily paid for themselves with 1 job. You do have to be aware of their limitations and proper stock prep. They really work best with square edged stock, because they only grip about .07 high.

[@mcskifter]

Oh, that's a much thinner bight than I thought. Nice!

[@00032599]

Would it not be quicker to machine off the excess stock, rather than taking the part to the bandsaw? Either way, nice video (as usual) and thanks for sharing.

[@outsidescrewball]

Enjoyed...lessons even for a non cnc guy....

[@joepie221]

Hey Chuck, Good to hear from you. Stay tuned for the 'Dogbone'. Its pretty cool.

[@chrisn3794]

Very nice I wonder if you could have done two parts out of stock by rotating one part 180• and orienting the larger side in the middle of the other part. It would probably be hard to separating the two though.

[@joepie221]

I could have nested them like that. I actually considered it. The problem I encountered was cutting them apart. Getting the saw blade between the 2 ends of the part was not going to happen easily.

[@chrisn3794]

Joe Pieczynski Man I had to make a few horseshoe shaped parts just recently and wanted to nest them interlaced with each other. But I ran into the same exact problem! Couldn’t think of a good way to separate the two. Had to ask you I just feel like there’s gotta be a way to utilize that stock. Anyways another awesome video. I truly appreciate you sharing your knowledge and you taking the time to reply. Parts looked beautiful. Thank you!

[@weenercatotto]

Joe, thanks for another great lesson. I wonder, if I had to produce a significant number of parts, would I prefer to use a solid stock and mill the parts off the end, then part- off the profile. Say, 3x4x10"

[@joepie221]

IF I had to make a bunch of these, I'd do it in a 3 foot long strip, 10 at a time and band saw off the parts. Deck the blank and repeat. simply offsetting all my tools each time I reloaded the blank.

[@CurmudgeonExtraordinaire]

Seems like the shapes could be nested / overlapped if inverted so that the end of one piece was inside the inner curve of another piece and increase the number of parts you could get out of a single length of material.

[@felgate11]

Wow Joe seems you're more up with the times than I thought!! Rotary tables - who needs them?? 20 grand or so buys a decent Haas vertical M/c + Renishaw probing system.

[@robertegan3889]

Awsome video. I've seen some guys spin their endmill in reverse, in the program, when its done cutting and out of the part, to knock that birds nest off.

[@joepie221]

Clever. I have to try that.

[@robertegan3889]

@@joepie221 I thought so too when I saw it.

[@ronwilken5219]

Joe, once again an excellent presentation. One thing you didn't elaborate on, was half of the order threaded and half drilled through as you showed? If all were drilled through what sort of nut was intended for the fasteners. I'm assuming a cap screw and a nut of some type. 🤞❄️🇨🇦🍌🥋🇺🇦🕊️🇺🇲👍

[@joepie221]

They got threaded.

[@gregnowling3128]

Could you make your soft jaws to match the area of material removed in the first op and eliminate the band saw operation ?

[@Steve_Just_Steve]

I'm sure you could but why? You would still have those large chunks of material that -could- probably will get jammed up when they come free and break your tool. Besides it gives you something to do while other parts are running. If its a big deal just machine those areas completely away on the fist op, that's what I normally do anyway so you don't have to worry or mess with it. Especially in aluminum when it takes very lil time to plow through it, also makes it easier to use a trochoidal tool path rather than slotting when you do.

[@billyraibourn758]

Hi Joe. Question about the drilling, is the part indexed in the vice some how to insure the holes are the same each time?

[@joepie221]

Yes, a hard stop is locating the parts the same each time.

[@Ccorniit]

Already few years old video, so hopefully still read. My question is, if you didn`t have bandsaw, how would have you done the second operation to get rid of the excess stock? Facemill I`m afraid would end up catastrophe when the stock lift up and jam between the stock and mill? Maybe endmill strictly follow the path of the clamp. Then once the excessive stock is cut loose, have optional stop and take the stock out and continue program? Or something else? Thanks.

[@joepie221]

On second operations, you always risk big chunks getting sucked up into the cutter. And, solid material is more valuable as scrap and misc pieces for jigs than chips. Thats why I cut on the bandsaw between parts. Plus a bandsaw is quicker if the CNC machine is already running. If you are leary about the corners or islands jamming the cutters, do a quick profile pass first on the second side op. Maybe you can use coolant pressure and direction to control where those chunks go. To be 100% safe, include an M1 in your code and blow them out of the way.

[@hodgepodgeenginerd1258]

How do you set you’re peck drilling parameters? While watching this video i noticed a lot of up and down travel and was wondering about saving time on cnc operations by fine tuning this feature.

[@joepie221]

This was a very cosmetic part and long drill chips whipping around was not preferred. The operation was either a deep hole, or peck cycle. My machine offers 3 choices. Drill is just straight through, peck is interrupted, and deep hole pulls the drill out of the hole all the way between pecks. My controller gives me complete control over the speed, feed rate, peck depth. My settings vary based on hole size, material and finish required.

[@shichae]

WOW, Not banging the stock in the vise before the first pass makes so much sense now! What is the preferred Grip Stock thickness you shoot for? I tried a similar approach to this earlier today on a set of parallel jaws, after watching your video on squaring stock. I left a 7”x3/4”x1/4” grip stock flat that I’ll finish decking the bottom off tomorrow, but I think I could’ve gotten away with 1/8” grip stock since the parts span the whole 6” Kurt vise jaw(s). Also when torquing the vice, what torque value would you suggest for Aluminum? Thanks again for the great content, I feel like Descartes standing on the shoulders of a giant when I watch your channel!

[@joepie221]

Many thanks.
