Tool by Tool List Operations & Positions If I am programming our 5 axis stuff, I stick with the same routine VMC stuff, I load a machine group for each operation

if gcodes link above doesn't work then first log in to www.mastercam.com and then click his link and it should work I noticed.

This is caused by a Bitdefender update http://kb.mastercam.com/KnowledgebaseArticle50759.aspx

There are switches in most posts that control this. Get familiar with them and your process will go that much better. On certain Trunnion machines Defining the planes has no real control on this. It is the switches that control this the best. Planes do help, but only to a point on Trunnion machines. Head Head machine the part don't move normally the head. That said on a DMU or Toyoda Nutating Head machine planes are all I use. Currently doing 30 thread milled holes and keeping the part facing the operator through all 30 holes. We have 48 Backspot holes and gain keep the tool facing the operator through all 48 holes do they can easily add and remove the back spot tool by hand. There was not way to get an Autofacer into this part. The thru hole to backspot face ratio was to great to overcome.

I would not use OPTI-ROUGH on those fins. I would waterline it to finish size and call it day. In case like this you will be a lot slower and never fully use the machine to it speed and feed doing it the way your trying to do it. Max RPM and .005 per tooth chip load with a finish step down and done. Part might move so if you are worried then leave stock doing a .05 to .1 step down to semi finish then come back and finish. Might look at a taper ball endmill to have that shape made into a custom tool and then 2D contour it is another way. Time you have the tool made and finish the profile with a custom made tool you will come out ahead if doing production. If this is a one off then do the Waterline and call it a day.

I clicked here because of massage...

There's a good chance of it working with the current version . Do take care, we only officially support inputs for about 4 or 5 releases at a time (when a product is "sunset" it's considered not actively supported anymore), so if you're not getting what you'd expect opening it directly in 2021, you probably have some deprecated functions or weird c hook stuff that isn't being ported correctly. I'd recommend that you go in 5 version increments, e.g., X5 > 2017 > 2021. I only have some MCX-5 files handy, but they still open fine for me in the daily build of 2022, for example.

We overcome this limitation of the Flowline toolpath, by using the Surface Finish Blend toolpath. If you look at your surfaces when they are unshaded, you'll see the surface grid lines which run in the UV directions of the original untrimmed surfaces. You are getting a conflict because the UV vectors of the surfaces don't match. Either that, or you can write separate flowline toolpaths for each surface. I've had to do this before when using version 6-8 of Mastercam. In Version 9 they introduced "Project-Blend" which is what the new Blend toolpath is based on.
