sorry to be so offtopic but does someone know a method to get back into an Instagram account..? I was stupid forgot the account password. I would love any tips you can give me!

@Khalid Alonso instablaster =)

@Esteban Jimmy thanks for your reply. I found the site through google and im waiting for the hacking stuff now. Takes a while so I will get back to you later when my account password hopefully is recovered.

@Esteban Jimmy It worked and I actually got access to my account again. I'm so happy:D Thanks so much, you really help me out !

@Khalid Alonso happy to help xD

Just got my first pierson pro pallet system after 1 year of machining irs amazing I've designen my first fixture might change it up

LOL, just promise to post the results on Instagram for everyone to.... "admire".

You're absolutely right. These clamps will indent into aluminum over time. I discussed the solution in this previous Fixture Friday: kzfaq.info/get/bejne/i9Rgmq92rdqcfJ8.html

Who makes them?

@@thomashenderson3901 mitee bite.

@@wuzup76020 Thanks!

I’ve been using Mitee Bite for a long time. I also use their jaws. Very good.

Thanks for asking! We use our Pro Pallet System. Loads of holding force. Here's a video on it: kzfaq.info/get/bejne/bqiEo7Sd25fMkYE.html Let us know what you think!

I’ve actually have a couple of pallets that take advantage of the fact that they can be loaded rotated 180 degrees on the PPS. Imagine a 2 op part that is held down by screws and you don’t actually want to move the part to the other position on the pallet, just change where the screws are holding the part for the second op. If you alternate the positions of the ops and rotate the pallet 180 degrees each time it lets you run the same program. You just need to make sure your X, Y zero is really correct with respect to the alignment pins on the pallet base when you are machining the pallet so you can be confident all the pallet features are in the same position when it is flipped.

@@swervedrivespecialties3827 but if you aren't actually moving the part, then why do a second op?

@@swervedrivespecialties3827 also, I was on an FRC team (192) in high school, and we did swerve drives too 😎

@@zeevyehuda2501 Second op because you need to machine where the screws were holding onto the part during the first op. That’s awesome. I remember seeing some of 192’s swerves on Chief Delphi.

You can replace a pocket that utilizes the back wall of the fixture to locate the part, with a series of dowel pins. By doing this, the part only touches the dowel in a very small section, which is essentially the tangent of a flat piece to the dowel, if that makes sense. I'm not a fan of pockets, if I can help it, since they do exactly what you described. You spend countless hours a month cleaning fixtures out of chips at best, and at worse, you risk the opportunity of one of those chips causing you to scrap a part. The fine art of fixture design has so many facets that most miss the high points. First, repeatability is at the top of the heap. Next is speed, the time spent loading and unloading. Then there's operator friendliness. No one wants to run a machine that kicks your butt all day. Lastly, is exactly what your issue is, cleanliness or at least the ability to be cleaned easily. Pockets, crevices and entrapments are death to a production shop. I've made thousands of fixtures over the years and my favorites were ones that were nothing more than a flat plate of ground A36, with a series of dowel pins sticking up and some of my custom "cam screws". Clean, fast, user friendly and 100% repeatable. Some of these fixtures I produced over 200,000 parts on without a hiccup. Jay is putting out some pretty good content for the novice fixture builder, and it's been in need for a long time, but once you graduate to 4th axis for your fixturing, it's a game changer of epic proportions. My largest part count to date was 276 pieces at a time in one push of the button, but I've done several that were over 80. Lotsa of folks are skipping over 4th axis and heading straight to 5th, which is really a mistake most of the time, as you're limited to just one part at a time, most of the time. 4th axis on a vertical, with a tombstone, and fixture plates, is a gamechanger, that on the lion share of parts I see being put on a 5th, would run circles around. I ran my first 4th axis tombstone on a Haas VF-2 in 1994 running 88 parts at a time.

On the bright side, we don't often forget the lessons we teach ourselves.

Good question! For aluminum, we typically hold between 0.090"-0.120" of material using the 3/4" clamp. For steel and stainless, we always use the recommended "D" dimension of 0.150".

@@PiersonWorkholding Thanks that helps a lot!

I think that horizontal line was meant to illustrate the height on the clamp of where the force is applied and not the direction.

I usually make mickey mouse ears in side walls of pitbull pocket, so back wall is flat in clamp size.

Or by broaching or by using smaller diameter endmills or by using a mating part that has an outside radius but EDM is the most expensive and slowest option and not recommended.

@@PiersonWorkholding agreed, rotary broaching would be cheaper. But if you got an EDM machine then I'd still go with that method.
