hi folks let's walk through how we put together our Dell Tronics parametric pin rack I think this project is awesome because it really highlights just how powerful and amazing parametric CAD it can be and I think this sort of a storage device can be really helpful for any machine shop the one you see here came out of a need to organize these Dell Tronics pin engages we care a lot about the diameter of the bores on our Sanders machine works fixture plates we machine them with a digital boring head and we want to hold a really accurate tolerance so we use a combination of metrology tools to check those diameters we have two different style of war gauges we have our mid to toy-u LH 000 height gauge but our go-to is the dell tronic gage pin sets these are amazing because they're actually relatively inexpensive somewhere between 00 and 00 dollars per pin we have them in increments of one ten thousandth of an inch and the go/no-go nature of them gives them much more consistent reading compared to some of the other metrology tools which are operator dependent the way in which you hold a bore gauge of the way in which you sweep it across can actually give you a slightly different reading as we collected more of these gauge pins though I realize we need a way to organize these and so Edie came up with this rack and the reason I think this project is awesome and we're sharing the file on the NYC CNC site is under modify change parameters this whole rack is built with user adjustable parametric values so it literally takes seconds to update the number of Bin's the width the rack height the angle the depth the dimension the thickness which makes this an awesome tool and if you have a co0 laser in your shop you can make one of these for incredibly cheap if you don't you can either sub it out send it out to a shop that has a laser checkout a makerspace that has a laser or you could also make one with a 0d printer or CNC machine especially a router style but really it's best suited for a laser so if you've never seen this change parameters or user parameters before let me walk you through a really good example if you head into your fusion 000 data panel scroll all the way down to cam samples workholding yours truly Saunders machine works we created this parametric mighty byte fixture it's a relatively simple fixture that you can build it can be mounted directly to a fixture plate or held in a vise but it's a good example of the value of using user parameters because we designed this so that it's much more intuitive for you to go in and make modification so having everything named with an intelligent name a name that means something makes it much easier to make edits to this file so in this case I have a stock Y of three inches so that's what's the piece of raw material that we're putting in here let's say it's actually four inches update that everything moves let's say we're only going to use three pit bulls and not five hit three it adjusts hit two it adjusts hit five it goes back so it'll adjust how far in is the first Talon grip let's change that from one inch to two inches moves them in let's say you're a knife maker and you're building a knife and you're thinking oh I don't need parametric values because we're not going to be updating these over time let's say the pivot pin diameter is always going to be 0.000 well I would argue think about still using that because can really help as you're building out your CAD file or working in a team environment let's create a user parameter called pivot dia and we'll say it's inches you're about 000 and we'll say the comment pivot in diameter now when we go to save model up our knife handle and let's say we've got our handle and we create the pivot pin circle instead of using an inch value just start typing P and it Auto populates a list of your user parameters come down here to pivot diameter hit enter and now it lists it as FX 0.000 but if you double click it you can see it's listed as pivot diameter when you're then designing another component or another sketch that references this you can use that pivot dia or you can even take it to the next level by doing something like change parameters new parameter pivot clearance and we'll say zero point zero zero zero five five tenths click OK and when we're designing its mate component we could say pivot dia whoops pivot dia plus pivot coherence and then when you're working with your drawings or your manufacturer or within the team and you realize you know what that's just too tight we need to change that you don't have to find this sketch you don't have to go hunting just come into your list scroll down to pivot clearance and change that to seven tenths or in this case let's make it extreme so you can see the difference mm ooh like so but it's the patterns that are really tricky so cus a while to figure these out and get them to a relatively stable and consistent behavior where you've got each little notch correctly spaced correct intervals matching the other patterns of the other dividers or components so I would encourage you to download this file poke through it there's some pretty clever and pretty creative formulas and again I don't want you guys have to reinvent the wheel so download this run with it modify it make it what you want the next thing I want to do is build a duplicate one of these but for our tools so for us on the tormach I have about 00 core tools I like to have the tools set up in good condition and know that they're tools that I can use especially when I'm using our sort of preset templates or tool libraries that way I can program offline get to the shop make a part and not feel like I've got to find a tool set up a tool etc but what's nice sometimes is if the tool is already in a holder I might want to leave a extra packet inserts or the actual endmill box or a duplicate of that tool set up assigned to sort of that tool number per se so my plan is to make a smaller rack like this in fact I really only need it to be 00 so let's make that edit right now by 0 I think I like the shape a little better because it takes up less footprint we can adjust the angle might actually mount it on the machine itself rather than have it on a cart and now I've got a little cubbyhole and I always know that this will be spot number 0 right here for that tour if I have to take a tool out to steal a holder for a new tool I can put that tool back there and I know that's always my tool number 0 and if you're wondering why this one's a little bit taller we had a divider to separate out our metric gauge pins which is I think another great example of it helps you see the design intent behind how a part was built and helps you more easily work on it or edit it for example on that section divider if I click on it once it underlines the little marching ants so I see that that's the component for it I could activate it edit that sketch it looks like it's just a number but again if I double click on the FX you can see okay section divider offset is a dimension off a projective dimension so that's clearly adding an offset to make that section divider slightly taller which helps me understand okay that's how that was programmed that's how that works go into modify change parameters scroll down save point two-five still too tall so 0.00 slightly taller if we go take it all the way to zero I think it gives me a fill-in error when I do this nope actually gives me a filter error if I go directly to zero I'm not sure why oh there it is just lost the reference edge that's okay so comment below I'm curious if this is helpful to people I find it's a great example of when you have the right tool at your disposal you make better decisions as a machinist or as a manufacturing entrepreneur if I have a spot to put that end mill that I want to say hey I was using this I'm gonna use it later I don't know where to put it I have a spot to put it makes me so much happier it makes me feel like I can run a clean shop and organize shop without extra effort without sacrificing time and efficiency hope you folks learned something hope you enjoyed take care
