Hi, so in this video we're going to start on the finishing process for this and I appreciate it doesn't quite look like it's ready for that yet but bear with me and we are initially going to start by cleaning up all of these interior profiles so we go back to the machining space and we're going to define a new setup stage which we are going to call finishing and we are going to define a contouring path at this point we're going to use the 3d contouring tool we're going to stick with the five millimeter spherical mill because the radius of a lot of these fillets is actually two and a half millimeters which is very convenient for our needs and we are going to grab these contours and we're going to define them as our contour paths so I'll just take a second to select all of these and we now have our first one defined so we will go to here and curve and we want our cutting tool to be on this line instead of inside it because that's the offset that we've got and we will quickly set the sixth axis control again and then go back to generate the toolpath and we should have a fairly clean toolpath from here we'll go to the axis map just to double check build the graph update the toolpath and we will now simulate this fortunately due to just being a simple contouring path it's a very quick simulation so if we click run we'll see how it swept around there and there's no excess material left over we'll do a quick verify compare and that entire region is now a nice green there's going to be a couple of small very clean up parts to do in here which is not the end of the world but it is worth taking note of however we can now copy and paste this particular solution for all of these panels all the way around so I'm going to quickly go around and select all of these I'm just going to pause the recording whilst I do so and once I've got that ready to go I'll come back to you shortly okay so as we can see here I've now selected all of these exterior curve lines I've kept them as separate curves where there's the small overlap regions here that we previously highlighted with our complex plane so we can now go into generating that toolpath and we can just double check the axis map again we should be coming extremely familiar with throughout the course of this video we update the toolpath and we are now going to go in for a quick simulation and we're going to check the verify compare tool and we can see now around all of these bases we've now got a much much cleaner much closer to the perfect zero mark than we did before which is ideal although I've noticed that we've not seen anything much going on with these bits so we're going to go back and the reason for this is because these final couple of tool passes are not set to be on the line they're set to be inside the line which is very much my mistake so I'm going to regenerate that this is something that's absolutely integral whenever you're dealing with contouring as well so it's a mistake that's worth noting and very much worth picking up and learning from so let's go back into simulation now and we'll rerun this while that's flipped around sorry about this let's quickly rerun now and once that's run we'll now do a verify compare and we can now see that all of these regions are lovely and clear and green which is exactly what we're after so we're now getting pretty close to a more viable finished part there is obviously a very small amount of excess deflection here we can go back and we can refine this scalloping paths that's not sorry scalloping these complex paths by enabling the scalloping check on them as well but I would like us to get to a stage where we've got a more complete part before we start fine-tuning the last details of it so we are now going to start looking at cleaning up all of these profiles as well so I am going to go back and we're going to use a 2d contouring path for this this time so it goes 2d contouring and we're going to select each of these curves so if I remember correctly all of the bores yet they had a little bit of excess on them so we're going to go around through all of these on the two separate level planes that we had determined before and we're going to select each of them and we are just going to just going to clean them out get them to final size so let's just grab the last of these and select those curves okay and obviously we want our contouring to be on the inside of these but we don't want there to be any excess to account for we're going to change the tool on this from a 20mm cylindrical mill to we're going to go with like a 4mm cylindrical tool so if we select this one for now and then we change the diameter on it accordingly and set it as a new tool we'll keep the lengths and everything the same for now we do the last little bits we need to do before we run it okay so we're going to quickly go through that tool path update and run now now if we simulate this we should see all of our bores get cleaned out and brought to the correct size at least all of our deep bores and then the shallow bores we'll do at the next pass it's very quickly check compare lovely green surfaces there this is exactly what we want to see now again as I say the difference between the solid model like this and the voxel model like this this is much much closer to actual real-world precision whereas the voxel model is significantly better for more organic forms because it's volumetrically defined instead of working off solids it does mean that it lacks a little bit of the final precision compared to this though so this for hard material surfacing is exceptional and cannot be beaten in my opinion so I'm going to turn that back off and we go back now and we're going to duplicate this 2d contouring path and we are going to redefine each of these parts that we're going to going to be cutting because we're not going to cut those ones we are instead going to go from beneath because these parts have got curved lines to them so I'm going to select that curve we are don't really need to go from underneath for these ones but we've got it so why not and we are going to grab that one as well before I forget don't know why I keep forgetting that one it's everybody's important as the we are going to define our top level and that should see us done for that so fixed vectors good generate the toolpath give it a second to think about it and then we check the axis map and we should be good to go so as my dog shaking his head in the background there okay so go to the axis map now to try and resolve these minor issues that are coming up we build the graph and we update the toolpath and that I believe is us ready to go so we go back into the simulation environment quickly run through these and we check and we've still got a bit blue in this one which is interesting so I think we're gonna have to quickly work through this bore again the rest of these balls all look good though so let's focus on this ball see what we can do about resolving that problem so at the moment we have got right so we've selected this face and I'm just noticing there's a slight deflection out here so what I'm to do is I am going to set another contour here let's go using this no not that line we use this line here okay so we've still got the same roughly the same contouring profile but it's just in a tiny bit from there we will duplicate this operation and we'll set this as a separate separate curve to cut we'll delete that because there is going to be a small amount of taper in there so I'm going to set this as the top level and I'm going to very quickly measure this because obviously we don't want to chew the taper that's in there just in case it becomes important later on that's well that's 0.
