  1. Josh, i am always learning and trying to develop my skills. I know how to machine this and make a toolpath for this by hand with pencil and paper if push come to shove if I had to. Hopefully he is helped and I have personalty helped him many times over the years and part the reason of why I am part of this forum and have not left. #1 to help those as best I can. Not that have it all figured out or even all that good plenty better than me. #2 is to get better and learn what I don't know. Thank you for doing both for not only me but for others I appreciate it.

  2. its cool, we are probably the only ones looking at this cuz the original poster has not even responded, maybe he is off for the holidays but there is no point of looking into this anymore in my opinion until he responds.

  3. Josh. I had 1" past on both sides and still didn't work. Must be something I am missing just like the revolve I where I had the wrong chain and it wasn't coming out correctly that Greg got working. Thanks and have a good day.

  4. yea trimming the solid with the surface worked for me but i did extend the surface past both ends of the solid as shown below. i always try to keep my surfaces extended past the solid i want to trim because if it falls short if can fail.

  5. I tired it originally and it wasn't coming out correctly. I now realize I drew that original rectangle wrong. Look on Level 1 you can see my mistake. Thank you for catching my mistake.

  6. Josh I went back and made a single Fence surface to try to do the Solid Trim to surface and I get a face imprint error. The way i went about creating the solid is the only way I can get to work. i have trimmed all kid of things over the years using trim to surface, but not a shape like this. Can you give ti a try and see what I am doing wrong? Thank you.

  7. If you looked at my file you will see I used fence surface to create a visual set of surfaces I could then use to make sure the shape I came up with was correct. I did try the fence surface as one surface to try to trim the solid and Mastercam didn't like it. I think that is because it was flush I think if I had offset the original surface .1 higher then projected the chains to that offset surface and made a fence surface that went through the correct amount it might have worked. I use Fence all the time for Multi Axis roughing and that is another way in which this part could be roughed. Make a floor surface by offsetting the conical surface the distance needed to be deep enough. Then use the fence surface and the wall check surface. Now a programmer has a completely different way to approaching roughing the part. Print called out taking 1-3/4 endmill and just machining it so they don't care about how it looks just want clearance and normally for these type of flanges it to allow air to get into the motor for cooling.

  8. yea i didn't draw a cone out but fence surface works of conical surfaces too of course. so even though the example in my image was a radial surface and not a conical surface it would still work for him i believe. There is more than one way to get this done it appears, your method looks like it worked but i bet this fence surface method is faster for me because i have used fence surfaces so much in the past. also after testing this it looks like fence surface builds it in just 1 surface so all that stuff i mentioned earlier about converting the geometry to a single spline is not needed since fence did a nice job of keeping it 1 single surface which is what we want to trim the solid.

  9. Josh not exactly what he was looking for. You doing it to a radial surface and he needs it to a conic surface. Need to draw the solid and then work from the conical surface. The trick is getting the start and end points, but not really all that hard once we do some basic CAD work. Heavy Metal I have made the solid without the simple stuff and detailed the levels and the solids manager to hopefully help you on your path to make your own solid. I went ahead and put a toolpath it to give you an idea how you could go about it. Not that is all that good just a way I would try to approach it. Mastercam file Here is a video of that part being cut in Machine sim. I also made a video showing how i moved the arcs to the start and end of the slots to help with model creation. Maching Slot in Machinesim Slot Creation start using Dynamic Transform

  10. since we cant extrude cut normal to a surface we can use fence surface to accomplish this task, and from there the surface can be used to cut the solid. First project the shape onto the surface (Transform Project) then convert the multiple entities to 1 spline (on the wireframe tab, click the drop down for Spline Manual and choose Spline from curves, choose the projected geometry and make sure to choose delete original curves so you are left with 1 single spline) Then create a surface from the face of the part, and use a Fence surface to build the slot. (found on surface tab, called Fence) which will get you to the point i am at in the image below.. Then the last step is if you want the slot cut through the solid to go to your solids tab and choose Trim to surface (found under the trim to plane dropdown) if the above doesn't make sense then if you can send your file i can put together an example.
