I did try that, it's nice in some areas but puts a lot of small cuts in areas i don't need them. I got close to what I need by playing with tolerances and then added one path in the toolpath editor even with the small steps box checked i get stepovers bigger than my maximum

Hello, I am trying to get a plunge roughing toolpath to follow a contour .nci chain and it does most of the stepovers at the correct distance, but it messes up around the curves. Does anyone have a quick solution to this? Thanks

Hello, I was wondering if this is till a feature in mastercam? or the Xform-STL? I have tried merging my STL so I can import the mesh and lines separately, but it doesn't give me the option. For now the file is too big and cannot be manipulated without the computer freezing Thanks

Hello, I discovered the nesting toolpaths operation today and was pretty excited to use it, until I found out it does not support multiaxis operations. Does anyone have a workaround for this or another way to do it? Thanks

@CEMENTHEAD Thank you, I have seen these options and have not experimented with them. Does TCP change the g93? My default is g96 but the tcp turns it into a g95. I tried just changing the code from g96 to g93 and did not notice a difference. I'm curious which notes you mean and who they're available to. @C^Millman Thanks, I've played with the tangency factor and have my default set to 10. I'm nervous about going all the way to 40 because I feel like it would be pretty far off from the part, and if it isn't, why wouldn't that be what everyone uses? I guess I'm just figuring it all out still. Like today, realized that the hi-speed toolpaths take a really long time with almost non-existent step-overs where a parallel spiral slows down at the corners but flies through everything else (even though it leaves stock in some places, I'll have to try the constant overlap spiral next). I had a particularly bad Swarf mill toolpath today. I played with it a bit and found that running at a .001mm tolerance at least slowed it down enough to keep it on the wall I was trying to cut. However, it also slowed it down significantly around a big smooth curve. I had the fanning and max angle step set to 1 (are these the same thing) and the minimize rotation axis changes checked - as well as the adjust feedrate on edges and for fanning checked. One thing I plan on doing for my next part is importing the solid file, converting it to surfaces, and only working with that to create the geometry/toolpaths. Will this provide me with a cleaner surface to generate a smoother toolpath? Thanks

Hello, if any of them could be improved I would like to know how, but yes the swarf is currently the only one that is jittering enough to gouge the part past the point of being able to sand smooth. We have a thermwood model 70 with thermwood control, and should have all the high speed options available, though I don't know specifically what you're referring to. I will try changing the max angle tolerance, that's something I haven't messed with yet. And yes, the swarf is tricky, I wish there was an option to keep the tilt as flat to the floor surface as possible

I have tried this, nothing shows up though

Hello I'm having trouble finding which settings to change to control the surface finish of the part after it's machined. I've lowered the tolerance from .025 mm to .01 mm and that helped, but I think there should be something else I can change to create a smooth toolpath rather than a jerky one that doesn't x100 the file size. Mostly it's just a little wobbly, when it's in 3-axis it leaves a pretty nice finish. When it switches to 5-ax however some movements are very rapid and have heavy jitters. We have a beast of a machine so rigidity and structure shouldn't be a problem. I'll upload the part to show what I'm working with, if anyone has recommendations on how to make a faster, smoother toolpath all help is appreciated. standoff mold rh.mcam

Hmm, I asked Mastercam about it and they said that I had untrimmed blanked parent surfaces with irregular surface norms. Now I've been trying to figure out where to find them...

So that answers my question for the second file, but the first is still creating the toolpath underneath the part. I've created a surface from the solid and made sure the surface normal was facing the right way, but the approach still comes from the bottom of the part and is on the wrong side of the line. Any help is appreciated Thanks

Hey thanks @C^Millman that helps a lot. I appreciate it. And yes I wasn't necessarily looking for a 'why doesn't this work for every part' but rather a way that it does work so that I may move on.

So I've been having trouble with this operation not creating a full toolpath or creating it on the wrong side of surface normal. Gonna post two files here to see if anyone can help. the second file is frustrating because it's the same part mirrored, and on one side the toolpath works, the other it doesn't.

Maybe it's partially in mastercam I just don't know why. for a lot of the code it has a very slight b value change (.08 degree) and continues to rotate the c axis every time. I just would like this to work the way it appears to. Messing with the multiax parallel toolpath I am still not getting the results I need. wheelpant plug lh inner finish.nc

I prefer using the raster with tilt as I only need this to be a 5-ax operation when the holder comes close to the part. I will try the multiax parallel but would really prefer to get this fixed. I do however, think it has to do with the post, not the toolpath in mastercam itself....

Hi friends. I'm having an issue with my toolpaths being very jittery and not providing a smooth finish. I'm using the 3D raster finishing toolpath with holder tilt turned on. I've used it with the holder tilt turned off, and it works wonderfully, albeit with some slow movements in seemingly smooth geometry. I've played with the tolerance filter in the operation, and found that the bigger the tolerance (.1 mm) causes jerky movements while a smaller tolerance (.01) makes a very smooth toolpath - when the holder tilt is turned off. Now that I've turned it on and effectively made this a 5ax operation, as soon as the holder tilt engages it returns to it's jerky motion. Another problem is that the holder tilt seems to engage when unnecessary, I have 2mm of holder clearance and the tilt occurs when it is nowhere near the part. Any help on generating a smoother toolpath would be great, I am posting with Thermwoods post and don't see anything in the post that would change the output of the toolpath other than tangency factor (which i have set to 20 at 1-40) and acceleration (which i have set to g05 at g01-g09) The toolpath already takes around 5 minutes to load in mastercam, so making the tolerance even smaller would be a pain, but is doable if that's what it takes. https://drive.google.com/file/d/1TksmPNQ7AYVUG1JzRJqLWS0X8_3ZtLgq/view?usp=sharing (operation 10) Thanks, Lucas

never mind, you have to go into parameters -> additional options -> planes(WCS) -> and change them all individually. Wish the edit library origin feature would just do that for all toolpaths selected...... not sure what it does.

Hello, I am trying to update the origin point that I will use for my toolpaths, I've already created a few and don't want to remake them. There is an option when you right click in the toolpath manager edit selected operations -> edit library origin. I can select the plane that I want and I hit the green check, but nothing changes. When I go back into the 'edit library origin' the previous plane is still selected, not the one I want. Any help thanks

Hi y'all, made one post already, solved it pretty quick. Thought I'd start another one for all my other questions. If you'd like to give a quick answer I'd appreciate it, but chances are I'll figure it out sooner or later. Right now I'm cutting the outside edge of this plate of honeycomb material, which has to be cut a certain way. The cut I'm trying to make is on a filleted chamfer on the outer perimeter. I'm using the multisurface command and using the one-way cut feature. I assumed (hoped) this would mean it would make a down cut from top to bottom of the part, retract return to the top of the part, then do the next top to bottom cut (to push the material downward). Instead, it's more of a zigzag pattern where when it returns to the top of the part it is doing so in a diagonal line while still on the cutting surface. Anyway to make it retract between each cut?

Ah, shoot. I done figured it out. I had been selecting the part surface as the floor but what I was chamfering already had the floor cut out. Just had to add a flat boundary surface and select that, sorry y'all. Thxbye

Hello, First post here. I've been figuring this program out as I go, but I've hit a snag I just can't figure out. I'm using the 5 axis swarf milling tool path to cut out a simple chamfer on the inside of a flat 8mm plate. So I'm chamfering the inside of the square, not the outside. When it gets to the corners and has to make the sharp edge where the chamfers merge, the tool extends past the floor surface, which I have checked in the cut pattern box and have a clearance of 0.1mm. This is a problem because I'm cutting a soft material and if I get into the MDF spoil board I'm afraid it will dull the bit. If I have to avoid those corners and cut them after the swarf tool path that is fine, but I don't want to get rid of the whole tool path. Or I suppose if I were cutting enough of these parts I could go in before hand and cut grooves in the fixture with a different tool. But surely there is a way to get this floor surface command to work. Dummy4.x_t
