hi folks put down that face milk let's walk through ten different ways you can face off your parts and let's talk about the benefits and the tips and tricks with each one both as it relates to the fusion 000 cam the tool you're using as well as the machine welcome to other Wednesday widget so first off is our go-to facing operation it comes out of the 0d menu within fusion 000 and that's a great time to talk about what is the difference between 0d and 0d well it's mislabeled because it's not really two-dimensional versus three-dimensional case in point 0d trace is able to move along three axis and 0d horizontal is generally a two or two-and-a-half axis motion profile so what's the difference between the two when you choose an item from the 0d menu fusion 000 has no idea what to do until you go into the geometry tab and you start selecting contours or faces and building up that tool path whereas in the 0d menu you don't have to do anything as soon as you've chosen operation you can actually click OK and fusion 000 looks at the whole solid model so much of our time in this menu is spent using the geometry tab to reduce that tool path to narrow it down to focus it in the areas that we want that's really important because it's the items in the 0d menu that generally lead to quicker use of templates or automatic tool pass whereas the 0d ones can sometimes be easier to control because you're only building up that tool path based on what you have selected the benefits of using face is that it's relatively simple to a little bit of a cheat because even though it's in the 0d menu it's still looking at the 0d model it's actually looking at the stock though not your model so in this case I chose the stock selections as that top surface because I want to limit the amount of time I'm cutting err the biggest items to focus on in the passes tab your past direction you can control relative to the x axis what angle you want your pass to go at so if we change that to 00 degrees you'll see 00 degree tool path more importantly pass extension will extend the pass left or right I actually like a stock offset especially when I'm using a tool like the tormach superfly the superfly doesn't really have a specific diameter because of the way that bar can be adjusted a lot of times I'll add 0.0 inches of stock offset tends to not increase my cut time at all and it makes sure I don't leave a little lip on the end of my part you can control whether it's climb conventional or both ways both ways has the benefit of zigzagging back and forth so it can save you a lot of time and some argue that when you're cutting over 00% of the tool diameter as we are here with a 00% step over it's not that big of a deal but suffice it to say that tends to be more specific to the depth of cut the tool and the material there's this option from other side if you're wondering what the heck does that mean or why is that even helpful notice right now our tools start in the bottom right of our part here we choose from other side it'll start in the top left where that's really handy is on a part like this that we just did for Johnny Five and when we face the first side it's only what you would expect it's starting at the top of the part and machining across it when I duplicate that operation and flip it over on the UMC to do the other side it's starting on the bottom of the part which I really don't like because it happens to become a slot so by checking from other side you can maintain the climb cut but have it start from the top of your part under the linking tab one of the most useful and perhaps not well-known features is extend before retract without that check the tool will lift as soon as it has finished clearing the material but not necessarily completely off the part with extend before retract checked it extends that tool path and in the lift does not happen until it's completely off of the partner the difference is much more noticeable if we switch to a large diameter tool like the superfly where you can see it starts the retract move as soon as it's reached just past centerline of the cutter whereas extend before retract forces the tool to continue all the way past the part before the lift it's a good time to talk about machine a tram and level and if you ever get the chance to talk shop with one of those crusty old to on die makers who's probably forgotten more than most of us ever know they will tell you yes all machines have some amount of error but you can use this to your advantage and many of them will know on their machine whether they want to cut left to right or where they want to cut front to back to use that tram error to their advantage or we can fight this by using a smaller diameter tool let's say we're facing across this part it's a five inch wide face we have a two inch diameter face smell and there's some head not very much exaggerated for the purpose of this demonstration you can see it's tipped forward so it's cutting lower at the front of tool than it is at the back at the tool and as we face across that part those very minut lines again exaggerated here represent the difference between the high side on the back edge of the tool and the low side on the front edge of the tool well if we switch that big face mill down to a really small end mill we can substantially minimize that tremor by reducing that distance to a fraction of what it would have been with a larger face mill yes using a smaller diameter tool does comment the cost of efficiency or productivity it's going to take longer to machine that part but it may well be worth it and it's something that's actually even done often in high-end work like molds where you have to have absolute perfect surface finishes and precision next up horizontal you'll find it under the 0d menu and the advantage of horizontal is it's a super fast tool path to apply and get a result with works really well when you just right click and store as a template the down sides a horizontal are many though the biggest of which is that the tool path works its way to the center of your part and then moves back out I wish you could do the opposite perhaps one day you can it's also not an adaptive style tool path doesn't maintain constant tool pressure or engagement you can see that here as we move into this corner the amount of cut that's being taken or the tool engagement angle of that cutter not only increases but more importantly it just changes it's not always an issue when we're taking relatively light size facing cuts but it still matters it still will most likely affect your finish or machine performance at some level despite those drawbacks it's still a useful tool path one example is on this part that we programmed for the project egress we did this on the UMC 000 and one hole tool path is able to take care of all of the finishing work on features at multiple different Z planes that's really useful you could also add a radial stock to leave to make sure your horizontal is only cleaning up the floor and saying off side walls that are better clean up with the 0d contour pro tip my favorite way of controlling where a horizontal tool that does work is with the heights tab you can see here it's machining just about everything let's say I only want it to machine that face under Heights we can select this face and one thousandth of an inch and we can tie our bottom height become our top height - a thousandth of an inch and it now only sees this plane as the acceptable area to do work and does a nice job of containing the toolpath to that face the other change that I will often make on horizontal is passes manual step over if we right-click on the maximum step over Edit expression you can see that the default is 00 percent of the tool diameter - any corner radius I'll often adjust that to be 00 percent again personal preference next up 0d contour and I'm guessing this is an operation that you had never thought of as a facing style operation here's the trick 0d contour I'm holding down the Alt key to select just that left hand line and if we click OK to pass on the wrong side we can flip that around we've got two problems here it's a 00 degree lead-in and it's too close so we can change our lead-in angle to zero degrees and we can then do two different things to extend that tool path number one is we can add a tangential extension distance the other options we can add in more lead-in distance anybody know the difference between those two the difference is that the linear lead-in distance will occur at the lead in feed rate whereas the tangential extension will occur at the feeding feed rate I also prefer it because I spend a lot more time in the geometry tab so I'm more likely to see if I made a conscious decision to change that value whereas it can sometimes feel buried or hidden over in the linking tab anything over the radius of the tool should be plenty then the trick is passes roughing passes we'll choose our step over we'll say 00% of the tool diameter and we'll just say a hundred just for the sake of the argument that's going to look ridiculous but then you can start to bring in model awareness by going to geometry stock contours choose that stock contour and it will now limit that tool path to areas where you have defined it as stock this is a very powerful way it's a very convenient and easy way to get a tool path that does what you're looking for it to do an example that pops into mind is well back when we made our dial test indicator gauge I had already done a 0d adaptive on this piece of tool steel and I just wanted to finish up this floor and give it a really good finish and I didn't want to use horizontal 0d contour allowed me to pick that edge limit the tool path to stock and control that step over next up adaptive you can use either 0d or 0d adaptive to get almost the same result I like 0d adaptive better because it leverages the solid model it makes it easier to apply that tool path to a template and have that preset up for your tool your machine your material for 0d adaptive under geometry you must select the face which is normally not the workflow I use normally I like to pick contours and deceivingly when you click a face it still says chain which to me kind of reads like a contour or selection of contours click OK it's going to default to a false smaller step over here adjust our step over to match we should be we should have replicated our recipe above yep perfect 0d adaptive clearing we just click OK we'll get a tool path but it's not going to be where and what we want so let's edit that we can set our bottom height to be the top of the model it's going to give us an error though because we've got to go back in choose a flat area detection you can turn off stock to leave look okay now we've got our tool path but it's inheriting the default stock from our set up which is this rectangular square so we're going to change that by selecting our stock selections as this face and that will limit the tool path down can adjust the step over to 0.0000 and that should now replicate what we had set up ahead of time yep there are two big problems with this that are related and that is you can potentially be left with a center sliver of material number one that might be unacceptable for your finish trying to face off apart and number two certain materials like titanium can be really hard on cutting tools if you're trying to machine off that last little sliver of material next up is parallel in fact the rest of these are all from the 0d menu and generally speaking we're moving away from what I would consider the more productive tool path and more into the aesthetic or creative tool paths parallel is just that it will move parallel to your x-axis just like the facing operation we can control that past direction with an angle if you have a peculiar shaped part you can use tool orientation to adjust that x axis angle let's say for example on this part we add a strange angle or feature to this if you don't want to measure that angle which you can't easily do and you can see it's a hundred and sixty five point one 000 degrees but more importantly if you just want that to be parametrically linked back under parallel to orientation we can select the x-axis as the line that moves our x-axis to be parallel to this and our tool path will now be parallel to that I think parallel really shines in its ability to add perpendicular passes which automatically adds passes at 00 degrees creates a little bit of a peculiar finish here in this example I wanted to do all the parts the same just to give you an apples-to-apples video but taking a look at the knurled handle that we did if you use a bull or a ball nose end well and you control that step over you can get a really good looking either fake knurling or textured surface one of the weaknesses of parallel is right now there isn't a natural way to extend that tool path off the part which I really don't like I'd really like to see them add that so what you have to do is hop into the design environment surface create offset click on that surface click OK if you're wondering that this looks tedious the answer is it's not that tedious but it's tedious enough that I wish there was a easier way modify extend and you can now use the patch environment to extend that surface hop back with that extended body we can now go into our parallel and under geometry you actually tell Fusion that that new feature that new body is part of the model that it should look at for this 0d feature so remember 0d features look at the saw model and it's a hack it now thinks it's got to do work on this so if we hide that you can see we get the result we're looking for you can obviously control this with the size of the patch that you've created it'll start that tool that off the part and continue all the way to the other side now the scallop tool path looks pretty boring but before you close this video it's actually important to understand what scallop is doing if you read the pop-up it creates passes as a constant distance from one by offsetting inwards along the surface basically it collapses them in and while this part isn't the best example scallop does give you a pretty interesting ability to control the aesthetic of a tool path taking a shape like this 0d scallop click OK you'll notice it's collapsed the tool path in very quick tool path to create but this is the tool path I really want so that's the awesome thing about having integrated CAD cam is we can hop in to the design environment p0 project we can project this sketch I don't need to include the projection link click OK I'll hide that body real quick and that will let me take a couple of these lines delete it I can just drag that over to there click finish and back to the manufacture space and now I can take that scallop tool path and I can change to a selection of that and it will collapse that tool path in and a manner that's very controllable it's a tool path generally better suited for true three-dimensional work but don't overlook it for facing the spiral tool path actually named pretty well it spirals out again not the best example of the part here but it's a part like this Geneva Drive mechanism where spiral can really shine by the fault the toolpath is model aware so it sees that it doesn't need to machine areas here where it would no longer be contacting the material but in this case I want it to continue it's probably about the same machining time arguably even faster to just continue through as if these grooves weren't there but more importantly I want that fluid machine motion so create a simple circular patch let that drive your tool path and you get a nice spiral to a path hopping into the passes tab lets you control inside or outside direction in this case starting from the outside and machine our way the radio toolpath super inefficient but arguably well worth it I always like to think of this as the sunburst toolpath a very cool look again we're just doing it here with a flat end mill but using a bulldozer or a ball nose end mill you can really take apart and tie in some artistic talent so they'll look and aesthetic of it very simple to a path to get started with and the magic happens inside the passes tab again with the ability to control whether it's moving outside in or inside out and the angular step over and last but certainly not least is the morph tool path morph might be one of my favorite tool paths it allows you to select two chains and it morphs or transitions the tool path from that first chain to that second change as it moves through it again much more commonly used for surfacing or finishing techniques but you can use it for a facing technique if we look at a slightly more interesting part you can see this morph tool pack starts out by hugging the left hand curve transitions to a straight line and then finishes off morphing into the radius on the right side of the part so folks hope you learned something hope you enjoyed something and I hope this makes you feel more comfortable and capable of using some of these toolbox this sort of work is what we love doing if we've turned that passion into a new company called proving cut proving cut is a video library of speeds and feeds but also so much more it allows you to search for cam strategies and speeds and feeds data by machine tool by the material by the cutting tool by the cam silent operation and what you get for each recipe is a video so that you can watch that cut happening a comprehensive list of all the speeds and feeds information photographs on the part that chips the cutting tool and more as well as a link for each recipe to automatically open that file in fusion 000 which can help you program parts much faster
