Carveco Maker speeds and feeds & tool paths for 3D machining

[Music] hello and welcome to this caf-co maker tutorial where we carry on from the last video where we brought this grayscale image into capital maker and we cleaned it up with the smooth relief tool so in this tutorial we are going to construct the tool paths for this and bearing in mind this is three feet three inches high which is a meter and so we're going to use some substantial tools to machine this so first off we go to you can get to the tool path by going here or you can get them by going here it's 3d machine relief so we want a machine the whole relief now we're going to step with a roughing and we are going to rough out let me see it's wood so you just scroll down till you come to the board and we're gonna use a actually the bull nose that we want to use is a twelve millimeter bolt a milk and we're going to select this and know that this is where a lot of people have quite a few problems working at the speed and feeds now it all depends on what machine you are operated if you're operating on a small hobby machine similar to an X cap well you're probably going to struggle with a twelve millimeter so you'd probably use a six millimeter but I I have a industrial machine so we're going to set the tool paths for industrial machine and pine or softwood so step over we can actually because this is a roughing we can make this a little a little bigger and we can say to two millimeters probably would be fair step down we're gonna I think what I'm going to do is go for millimeters feed right you know my machine like I say is an industrial machine so I can really rip into this with a with this big tool and I can do probably 80 millimeters per second which is approximately what three and a half inches something like that just under three and a half inches a plunge rate now I normally run the plunge rate at 50 percent of what the feed rate is so that's 40 millimeters now because you run in these figures really high the feed and plunge rate you need to increase the spindle speed to contend with it now I know through experience that we would need 18,000 rpm if you took this up to 20,000 rpm the chances are that you may start to chair or both some of the wood in some blazes so that eighteen thousand is okay I'm gonna leave this as tool number one so we're going to use a standard raster in this case we want a machine in both directions so that means when the tool comes in here it's going to machine this direction and it's going to machine on the return journey we'll leave that as it is now I always use ramp in moves it just stops the tool just being dug straight in and you know it's kind of tear your equipment so that's what we'll do now then let's set up this safe height okay well ten millimeters above the material is fine and I always set the both of these same no the reason I said it a ten millimeter is because I always set my Z zero on the top of the material not the machine bed if it was the machine if I was setting it on the machine bed then I would whatever the material thickness is 50 millimeter of whatever it is I would then increase this to 60 millimeter to be doubly sure you can save 50 millimeters which is which is you know roughly two inches and just checks ok mana position and zero top of the block and we're gonna okay that and I abbreviate everything but sometimes you can understand what it is it's fine [Music] okay so there's a roughing tool path I like to do this in two separate sections then I mean there is a facility here if we go back into the 3d machining caf-co does have a facility where you can do the finishing and the roughing just personal preference I like to do it separately okay now for something this size probably a I'm gonna go to do this with a three millimeter ball mill so we're going to select that tool [Music] classic rustic should be fine [Music] so let's so now we're going to set up the cut for this tool like three of a millimeter that's that's fine otherwise there's going to be a million tool paths if I to set this at point one or something like that so for a model of this size this is fine step down now to make sure that we do this in one pass I'm going to set this at five millimeters and we're going to do 60 millimeters of feed rate per second 30 i normally set the plunge rate at fifty percent of what the feed rate is okay now then because we're pushing the tool at 60 millimeters per second we need to raise this up substantially so we're going to say 24,000 rpm this will ensure of a good clean cut and you know removing all the swarf as well this is we're gonna call it tool number two although I do not have a tool changer on my machine okay [Music] this is all okay we're going to leave it all as it is and here we're going to say this is I Bri v8 everything vanishing sauce is cut to I'd say three millimeter all male and now we're going to calculate [Music] and there it is an awful lot of toolpaths there so we're going to come into this now and now we're going to simulate now I like to the assimilating tool is there but I actually like to get at it from here and there it is I've got this set on fast simulate and believe it or not that was tooth toolpaths I've got quite a quick computer is a fairly modern computer and now what we're going to do is if I open simulate there again it opens this dialog box where you can change the material at the moment it seems something like pewter so no what we're going to do we're going to say no there is a big listing of of polished brass it might be a little bit reflectiveness have a look fly yeah a little bit too reflective it looks more silver than brass because it's polished I suppose and there's the pewter [Music] and then we come into the woods [Music] I mean Jenny would would be okay too but I quite like the representation of bronze here we go okay now I I quite like the look of bronze for this young lady if we move the 3d model around you can see that it is fairly fairly reasonable considering we took this as a grayscale straight off the internet for into the entry level of calf:cow which is Capcom acre and I will remind people that can co maker is $90 on top of that you get an additional 5% discount with my discount cold which is at the end of this video and underneath this video above the comment section so the next job to do now is to save the toolpaths now a lot of people have some problems with this so I'm gonna show you exactly what to do so what I do is go onto tool pass here which opens up this dialog box and you go on to the icon for a floppy disk and you will find the tool pass here so we're going to put them both over onto this side for the moment and we're gonna say okay first one and we are going to put it on the desktop make it as one lick test to cut one another I'm going to show you how to save this in a standard g-code file so you open this up and you can scroll you know there is literally hundreds hundreds and hundreds of different machines that caf-co has specific code for his house and yes you can do metal machine in very well with carob code and in future tutorials I will show you how to do it really these the difference between cutting or machine is metal and machine in wood obviously is the speed thebes and stepovers and we will come into that it'll stay that in mark even Mac Mac rotary axis [Music] it's a bushy anyway the list goes on and on Roland [Music] you know these are all post processes that have been made specifically for these machines and I brought you all the way down here to show you Tomek I've had a number of people every week asked me if it will post code for the tort or Mac and here it is there's tormak so we'll go back up here now if you have a router machine that isn't listed in here you come all the way down to wherever Gee Gee Gee Gee [Music] here we go now this is standard G code this trip you can either depending on how your machine is set up if your machine is set up in inches and your opera you're actually calculating in inches in caf-co this is the one that you would use says g-code inch tap every machine will understand this g code my case millimeter says g code millimeter tap so if you have a imported or locally made or one that you've put together this is the one to use so we're gonna save that and this as quick as that put this one back finishing cut just to cut to like I say I always say I briefly ate him did that wrong didn't I so it's we're just going to put test cut to and safe before you lose it again okay and that's it of course those colds now are on my desktop and one day I meet me machine this as well because I think it's a beautiful figure beautiful figure and of course this is going to be quite large and I think it it would be you know really really nice to be hanging on someone's wall okay well thank you for joining me for this tutorial this second half of this one has been quite lengthy but I think you you know I like to put everything I can into these videos sometimes they're 30 or 40 minutes long it's unavoidable so thank you for joining me and if there's something in particular that you would like to see please leave a comment and I'll see what I can do don't forget the caracal discount code will be coming up at the end of this video and underneath this video in the comment section and if you would like to visit my patreon page and become a patron that would be also great so press like subscribe and please join me next time bye for now [Music]
