How To Get Started With CAM Within Fusion 360 — Tutorial

hi my name is Lars Kristensen in this video I'm going to show you how to apply to a path to this path from start to finish fusion 360 [Music] so we're gonna start out by going from the model space to the kam workspace with in fusion 360 now the first thing you always have to do is you have to create a set up this is where are we gonna tell the software where x and y and z is out at our machine see out of the machine is pretty straight forward borders up and down but when it comes to a cam software that's a little bit more flexibility see you'll get files from designers and engineers where they model things that you will not agree are up and down top of front so start from the top and work our way down the first check box is what type of operation it is and we can just leave that because this is a milling operation the next is where we're going to define that XY and Z or the work coordinate system and you will see that we can't like ever try it that represents that here on the screen now if you click the drop down you will see that there's a lot of options in the drop-down in here but honestly I only use one the first one right here select z axis and the x axis so click on that one and you get kind of like two areas you can put in you can do the z axis or you can put in the x axis now you will see that the z axis here is already compressed the z axis will flip the blue z axis over here now there is a simple rule for this if you click a face or a plane that X's will go perpendicular to that face of plane if you select an edge then the X's will go along that one so with the z axis compressed right now being like blue if I hover over you will see that when I click on this that the z axis will jump and be perpendicular to that face you'll see that right there now if we wanted to we could also change the X and the y so the x axis right now is compressed in now if I wanted to I could select a face and it will go perpendicular to that face oh I could select and ads and it will go along that so if I select this ads you will see that the x-axis in rad is gonna flip in that direction now I can again go back and click over here I can hit the red eggs take it away and it will jump back to where it is so this is probably the hardest thing when it comes to using camera in fusion 360 so the rule is simple you click a face or plane and the axis will go perpendicular to this you click an adze and it will go along it so that's all you really need to to know about now below here we have stock point if I click on that you will see we get these small snowballs that appear on our model and this is really where we're gonna define where we're gonna pick up the pot out of the machine now if you are a dime a core you might like to select an ass so you can place an X here and it will step to wherever snowball you click on here now if you are a mold maker you might want to select the center of the pot that's where I'm going to leave mine right now so imagine that we're standing out in front of the machine and I used two indicators to tramming the part and I'm standing right on top of it with the X and the y and the z X is going going up and down the next tab is where we can define our stock now by default it goes to relative size box but means that the software have kind of like placed this box around the model now you can add a little bit of extra stock in here but I also want you to be aware that there's other options in here there's for example fixed size box this one here is great if you have this stock in your hand and you can actually measure it and input the numbers and then it's also a option in here that's called from solid you can actually model up all your stock inside of fusion 360 and then use it as your stock for simulation this is great if you have like castings that the I'm gonna switch it back to relative size box and make sure that there's a little bit of extra stock added to the sides and to the top this is really all we need to create this setup so now we are ready to apply our first tool path now for this part here we actually gonna be switching between two and a half axes and then free X's tool path so you will see how easy it is to jump back and forth between the two I'm gonna start out with a standard 2d facing operation it's pretty standard one and I click on that and you will see the menu opens over here now a couple of things that I need to highlight first of all you see these five tabs over here they will always be had the same function and being the same order no matter what tool path you in and that also goes for turning and it goes for like five axes so it's easy to remember what each tab does because they're all in the same order they have the same functions now the first tab is always where you select your tool so just like as if you are out on the shop floor you can't like have your part your stock the next thing you will do is you will try to find some tooling so I'm gonna click select tool and it will open up the to a library now that's a lot of different tools in here I'm just gonna scroll down to the bottom and now here there is a tutorial folder then it's for ends and I'm going to click on that and most shops would have some kind of like a face mill or a big insert cutter to face off the pot but just for this example to kind of keep our tooling limited down to a smaller amount I'm just gonna select a half inch flat end mill for this and hit OK now you will also see that we can put in our feats and speeds in here we'll come back so feeds and speeds a little bit later so the first tab is the tool the second tab is our geometry now when I click on that you will see on the screen that fusion 360 puts an orange boundary box around our part so the surfer is smart enough to know that we are in a facing operation and it says well you probably just want to face off the entire park now we're gonna come back to this boundary box a little bit later and change it but for right now let's just hit okay and just like that we have our first operation created we could always go up here to the simulate button and we can go ahead and we can simulate the toolpath really giving us a view into the future to see what's gonna happen when we click out on on the green bottom the green cycle start out on the machine so this was a 2d facing operation the next tool path I'm gonna go and use is a 3d adaptive clearing so right click on that and again you will see the fire taps of the same and again as before the first tab is our tool now you will see that it remembers the previous tool that was selected so we actually okay with that and like I said before feats and speeds that's we're gonna come to that later now many times when I'm programming things inside of fusion 360 I just select my operation I select my tool and then I just go and hit OK to see what the software will give me instead of going in and make like a ton of different changes and then have to go through afterwards and kind of figuring it out it's a lot easier to just select your tool hit OK and see what the software gives you now one thing I see here is that in this case the tool is X machining all the way to the bottom of the park now I was kind of planning on holding this part in a vise so I don't want a machine all the way down there now to edit that let's go back over to the operation right-click and select edit part so the first tab was our tool the second tab was our geometry the third tab is where we can select our heights down at the bottom here you will see that the tool is going to the model bottom but I can actually just add an offset right here so so it's planning on holding on to a half an inch and then I'm just gonna add another 100,000 just for kind of like safety so you can see how we can actually do math right inside of these dialog boxes the fall tab is the passes tab that has everything to do with the cutter engaged with the material there's a couple of things I want you to be aware of in here first of all this adaptive tool path is really a tool path that will analyze the stock to be specified and the model that we have on the screen and then it will calculate a constant step over for the tool so what we can actually do in here we can exit machine with a full flute length of the cutter so finally utilizing the hole flute length that you actually paid for now with that we can then control how much load we want to put on the side of the cutter now this here is by default two hundred thousands I'm planning on machining this part in something like 6061 aluminum um so two hundred thousands on like a has VF to is probably pretty close to what we want but if you want to be conservative let's change it to a hundred thousand also notice how there is a stop to lead down here so we're leaving some material for a finishing Cotter I'm gonna go ahead and hit OK and let's take a look at what we got now if you have never used a depth before one of the way is to check this is to go in and simulate so I'm gonna click on set up one what means that we're now selecting both are facing and our adaptive and I'm gonna go back over to the simulate tool but this time you will see first of all that we have a lot of blue lines on the screen we can go over here to the mode and we can change that to tail second of all we can also turn on stop which is a really great way to visualize what's gonna happen out of the machine so I'm gonna hit play and we'll see that we're gonna get our facing operation let me just speed it up down on the slide around a little bit so there's our facing operation and then you will see the adaptive clearing that's gonna keep a constant load on the cutter kind of like side milling its way through this part now adaptive clearing is smart enough to know the size of the tool versus the part so you will see that this clover section up here was not cut because the end mill is simply too big so let's take care of that I'm gonna close out of the simulation and for this that's going to explore the 2d adaptive clearing click on that and again you will see that the tool is the first tab that comes up here so I'm gonna go into the tool library I'm gonna go back down to our tutorial inch and this time I'm gonna select a quarter inch flat end mill and hit okay now the second tab is the geometry and I'm going to make sure that I select that inner edge of the clover here and I'm gonna go ahead and hit OK now if we zoom in a little you will see that we get a very unified cutting path down at the bottom and you will also see that we entering the stock with a helix now here's a neat thing if we go back in and edit this 2d adaptive by right-clicking and hit edit and we go to the last tab this is where we control all our lead-ins and leads out you will see that we have a ramp taper angle if I'm changing this to ten and hitting OK you will see they will now get a cone shape helix this will put a lot less stress on the z-axis on your machine and simply just a better way to enter the park now I want to get back to that facing operation we had in the beginning now where we have removed all this material one could argue that this facing operation really only need to establish in a smaller surface at any point we can take an operation over here we can drag and drop it down on the order so now our facing operation is the last operation down here and then we can right-click go ahead and hit edit and if you go to the geometry tab we can actually select an edge and confine it within that area so now let's hit OK go back and hit setup so we select all our different operations hit the simulate button and if you want to fast-forward to the facing operation we can literally just go and click on it in the tree and you will see the software will fess right to that moment and if we now hit play we can see what we got now you see how a little bit of a tab is left over here now fusion 360 is absolutely easy to program but it also has all the functions that you would expect an advanced cam system to have so let's close out of the simulation go back into the facing operation by right clicking and select edit and then go over to the passes hab and we can do a stock offset of a hundred thousand now let's go back and hit set up its simulation fast-forward by selecting the facing operation and it is play again you that should do it now going back from A to D to a 3d toolpath I want to introduce you to a tool path called horizontal now when we're talking 3d tool path many times we are thinking of 3d surfaces that has curves on it but the truth is that most of the times there's also flat spots within those areas that's where this tool paths yarns so I'm going to select that and this time I'm going to go over and select that quarter inch end mill we had before it okay pizzas pizza for later I'm gonna go to our selection tab in here and then where it says machine boundary and I hit the drop down I'm gonna hit selection and select boundaries that we want that crow song to work within now you will see that there's a control containment over here and I'm gonna change the true tool center of boundary what means that I'm telling the tool that I wanted to stay on the line of our boundary but by adding an extra hundred thousands I'm telling the software that it's allowed to travel outside to go in and enter the pot from the outside now again at any time you can click setup you can simulate and we can fast forwards with that operation you now going from the three axis horizontal I'm gonna jump back and use the 2d pocket to finish the clover and also finish the two open pockets at each end I'm gonna leave it at the quarter inch flat end mill I'm gonna go to the armory tab and I'm gonna select the inside of the clover and I'm gonna select right here on the edge of the two pockets now notice how the pocket is also taken our stock in such a consideration I'm gonna go over on the pastures tab and make sure that we turn on finishing toolpath just to make sure that we get one clean up pass in there and also since this is going to be a finishing operation I'm gonna turn off stop to leave and here okay now I notice that on the clover we actually getting another helix but since we already roughed this out with a 2d adaptive we can save some as chaining time by going over right-click and if you remember the last step of everything to do we lead and lead out and we change the helix to a plunge and hit OK now again as your programming inside of fusion 360 I will always recommend that you go and take a look at the future and this way here we can always go and keep an eye on the different tool paths we got and see that we're getting close to have this part completely programmed you now we're almost there let's apply some to a path to this cone shape for this I'm going to use a 3d contour tool path now since this is a cone shaped surface machining we're gonna go and select a ball end mil so go down to our tutorial library and I'm gonna select a quarter inch ball and hit OK now since we have some material left over from a roughing operation I'm gonna make this a semi finishing operation so first I'm gonna go in and swirl geometry and just like we did with the horizontal tool path I'm gonna go in and hit selection and I'm gonna select our boundary we want the tool to work within I'm also going to turn on contact point boundary this here will make sure that there's a contact point that is tangent to our cutter now you can always hover over one of these boxes and this pop-up will show up where you can read more about it now we're go into the passes tab since this is gonna be a semi finish rough I'm gonna go and make sure that I turn stock to leave on and I'm gonna just leave ten thousandths in here for our finishing cut now I will also leave the maximum step-down at forty thousands and hit OK now when it comes to Freda toolpaths there's always two factors there's surface finish and then there's time time equals money right so the smallest step you're making define a surface you get but also the longer the cycle is going to take so let's go ahead and get our feets and speeds right so we can make an educated decision on the step over for our surface finish we can always access our tools by going up to the tool library man as you're up here and to edit our feats and speeds I'm gonna right click on our half inch flat end mill select edit tool and go to the feeds and speeds tab now feeds and speeds really depend on what kind of tooling and what machine you have so you have to use your best judgment but I'm gonna machine this out of 6061 aluminum or some kind of a soft steel on a has V of two machine so I'm gonna change my surface speed to a thousand and I'm gonna chain change my feet per tooth to 2,000 that should be fairly conservative for this machine I'm gonna hit okay say yes that I want to change these features beats then I'm gonna go to our quadrants flat end mill right-click hit edit now this color is a little bit smaller so I'm gonna change this value to 800 surface feet and change my feet per tooth to 1000 for our ball end mil since it only kinda like have to clean up what was left over from the adaptive and the finish tool path I'm gonna change my surface feature 400 inches per minute but changed my feet per tooth to 2,000 changed our three tools let's exit out of the tool manager now you will notice over in our tree that all our operation has a red exclamation mark that is because the software is fine enough to know that we changed all the feeds and speeds for the tool all we have to do is right-click on the setup and we can say generate tool paths now to check defeats and speeds we can go over and click on our contour tool path right click and we can select machining time we can see that machining time is just under five minutes that gives me the confidence that we can get a good surface finish in a reasonable time for our finishing toolpath now instead of going up to the ribbon bar and redo all our selections for our finishing contour to a path I'm just gonna right click on the operation go down to create derived operation and pick a 3d contour tool path here this will assure that all the settings we have from the previous tool path is covered so this new one so we really don't have a few things we got to change on this one first of all since this is the finishing toolpath we're gonna turn off stop to leave and then when it comes to the step ol just for fun let's change it to 100,000 now this is probably too fine and we'll take too long but let's just hit OK see the cool thing is with fusion 360 we have the options to go ahead and explore these kind of things before we actually have to make a decision so let's right-click on that operation and select machining time now you will see the machining time is over two hours now the surface is gonna look fantastic but I think that we need to keep this whole machining under one hour so let's close this out go back into our 3d contour select edit and change the step over to 5000 now when we right-click and we select machining time we would see that we are just below 30 minutes what I think will fit within the surface finish and with the time it's gonna take to machine this part now we also have to finish the outside perimeter so I'm going to go from a 3d contour to a 2d contour tool path again to no one's surprise first tab is always where we select our tool and I'm gonna go back it's like that happens and will be used at the beginning and hit OK when it comes to the geometry selection I'm gonna select the bottom edge of our part because I know on the heights tab we can always make a change in this case 600 thousands just like we had from the adaptive hit okay now this tool path comes out great but I want to show you a little trick you see here how the leading lead out comes right on the center of this face now if you have ever had any experience with CNC milling you know that the cutter gets sucked in right at the leading lead out entry leaving a tiny little mark here's a neat trick let's go back and right click on our contour select edit and if we go to the last linking tab and we select entry position you can select that edge hit OK and now the leading lead out will start right on that adds leave a much more professional part now the last tool path we're gonna apply to this pot it's gonna make anybody who have to handle this part after come out of the machine heavy let's do some deburring here a fusion 360 have a fantastic tool path it's called 2d chamfer now the neat thing about this tool path is that it knows what is on the screen I'm gonna select that go to our tooling library scroll down to our tutorial ins library and select a chamfer milled and hit OK now when it comes to geometry selection I'm gonna select the top of the pocket to no one's surprise I'm gonna select the outside ads and then maybe somebody will be interested to see that I'm selecting the end ads of each of the open pockets anybody who ever had any experience with deburring with a CNC mill knows that there's a big risk for gouging but the cool thing about fusion 360 is that the 2d chamfer tool knows that there's something there I'm gonna go to the passes tab change the chamfer width to 20 thousands and hit OK now you will see on the screen here that the toolpath is short but the best way to really look at this is probably hitting setup go to simulate let's fast forward to a 2d chamfer tool you you now notice how the tool comes in makes a nice chamfer but stay safely away to hit any of the edges with this we don't have a few things to do first let's go back into our to a library and make sure that we have the right order of our tool if you right-click in this white space you can select renumber tools the default is fine here hit OK close out now you will see that our tool is correct second thing we want to do is we want to go and create a setup sheet we can bring out to the machine now this customizable setup sheet will have all the information an operator want to know including all the tooling information and feeds its feeds last thing and maybe most important is the xyg code to run the part I'm gonna hit the post processing tab and you will see all the different post that ships with fusion 360 with that all we have to do it hit the post button and the code that our CNC machine needs is available for us to go and exit make chips I hope that you found this video helpful I hope it gave you the confidence to go out and test out this pot on your CNC mill if you like the video do me a favor hit the thumbs up if you don't hey be honest then hit the thumbs down and we haven't already I would really appreciate if you hit that subscribe button until next time have an awesome day
