The siemens 840D control has a cycle 800 (Swivel cycle) and also Traori (Tool center point control). These features make it possible to set your part anywhere on the table and the control will calculate and output the appropiate moves. It all gets complicated to interperate on the machine for the operator but does work well. You will need a post that can activate these options. Most of our work is positioning therefore we have elected not to use these features and instead just program the orgins as we wish on the part using worl offsets. If we do start doing live 4th and 5th axis work we plan on programming from the center of rotation as this is a vertical machine without a tilting head. I haven't figured an advantage to using the cycle 800 or Traori at this time with a table/table type machine except that if the fixturing changes from what I programed I wouldn't have to move the geometry in mastercam and repost. But like I said I'll worry about that when/if we start doing live 4/5th axis work.

What control is on this machine?

do you think the draftsman could have made a typo?

Appears that we just have to deal with it. I and many others are quite unsatisfied with verify. I believe that it is from module works and likely wont be fixed for quite some time. Apparently mastercam is devoting much of there resourses developing Mill-Turn. I've read many post about this issue without any real definative reply except get a better computer.

Why not post a subroutine with your old dyna post and again with the new haas post and see what the drifference is if any. Then you'll have an idea of what you need to do.

Bunches, It would be much easier to modify an already exsisting 5 axis post then to attempt to create all the 5 axis logic into a 3 axis post. I would suggest that if you don't know what you need for code then a good starting point would aquiring that 3 axis post that Foghorn offered up and try it on some 3 axis toolpaths. When you get it all working well on the 3 axis toolpaths you can then take that knowledge and apply it into the generic 5 axis post, As colin had suggested. The generic 5 axis post is a work of art but will require some understanding of which I would recommend Taking Colins 5 Axis post class (Eapprentice.net) which covers that post and all of its switches, settings and options, I like you had quite a bit of 3 and 4 axis post editing experience but would not have had a chance of creating a siemens post for our DMU50 without the knowledge I gained from this class.

A 4 axis machine would be done in the machine definition.

Yes I noticed it also. wish it would get fixed.

I only built i machine myself, If you can send your machine folder I'll try it and see if I can figure it out.

Yes when I first tried your program I got multiple work offsets but as MSL and ron said I changed the work offset to 0 instead of -1 and all was good. I did get an error log running your post but didn't have time to check it out, maybe tomorrow I'll have a chance to take a look.

Are you using a lot of colors, If so maybe just use a couple of basic colors to see if that is the problem.

Hi Wes Yes the taper angle appears to be the problem, in so much as it is what is being defined in active reports as a tip angle on endmills. I could change it to 180* but then I won't get a proper shank transition in backplot. Showing the shank angle is very handy on miniture endmills working in very tight areas. Also if I do that I'll have ball end-mills showing a 180* tip angle which is a bit bogus for the operator at the machine. Thanks

If I create all my flat endmills as bullmills with 0 radius the tip angle is correct at 180 degrees. I don't list the end mill type in my tool list so is there any reason that I shouldn't do this. Thanks

Thought Id let every know that on the other forum Ken from CNC Software analyzed my file and we've come to the conclusion the I need to do some updating to my computer. namely minimum 16g of ram and a solid State drive. Thanks all Dave

I can't understand that when I create a detailed tool list in active reports X8 the tip angle of a flat endmill is 45* but on a bullmill the tip angle is correct at180*. It was the same way in X5, Can anyone explain the logic here or how to fix this. The operators think I want them to use a chamfer mill. Attached is a copy of my simple mill tool list. all the flat endmills are 45 have a 45 degree tip angle tool list (mill-simple).pdf

If you moved the stl data you may have to redefine it as your stock, just a thought.

Thanks Cathedral Cjep Can I add that line into any post and mp will use it or is that a user variable that I'll have to add my own logic to. Thanks Dave

Glad to see its not just me.

5th Axis Yes I fully agree that there are more complicated and better ways of accomplishing this. Just adding the * would be great, I tried adding the * before the n$ on that line and it did not change anything could you elaborate a little bit on where to place to * Thanks much Dave

Thank you sir for the reply's I've worked the speed and precision to death and I've turned the memory allocation up to 85%. Being three versions behind is why I decided to ask for some advise. Have a great weekend yourself

Hello, Using the verify in X8 appears very slow and has poor resolution. The same file and complex stl stock file in X5 works much quicker with much better resolution. Hard to believe that the mastercam verify has regressed in performance, can anyone offer guidance in how to go about setting up the verify/simulator properly. Thanks

cncgotoguy this is a great concept. Colin Thanks for the input.

The quickest and easiest way would be to mass delete all of the "n$," and then replace the "n$," at the toolchange line at the start of file and toolchange call. Then in the operations manager, properties, tool setting page, Change sequence # start to 10 and increment to 10. Be sure to save the post as a different name before editing.
