Need a little help with Profile.

[ckirchen]

Hi all,


I have two questions with Profile:


1. Is there a parameter that forces ProNC to finish once surface/region before moving on to others? In this example, I have six surfaces to machine and if I select them all in one sequence, ProNC will do one pass of the first surface, do one pass on the second surface, and so on. The cycle time ends up being quite long because of all the unecessary moves. I know I can make it do what I wantby making six individual Profile sequences, but I feel that is unecessary. If I have to do it, I will becausesix surfaces is not that bad; I am more concerned about when its in the 10s or 100s of surfaces.





2. If you look closely at the left-most surface, there is an unmachined portion there. When I Profile it all by itself, the entire surface is machined. Why does ProNC remove some of the toolpath when all six surfaces are selected?





By the way, the surfaces were created with Mill Surface>Insert>Advanced>Sloped, and they are the steeper than 45

I don't think you can cram two or more separate surfaces in the Profile Sequence without the tool jumping back and forth between them.... anyone else?

It is going to step down through each slice as it looks
at all the surfaces, resulting in a lot of wasted
motion; you can't make it concentrate on one area in a
profile sequence. You also won't be able to apply
CUTCOM to each surface, it will turn it on at the first
surf and off at the last one.

You're either going to need to do a trajectory sequence,
with motions for each surface, or you are going to have
to try to get a mill window that does it for you - but
that will be problematic.

Good luck.

chris,


you might be able to get it with surface milling type 3 with 2 sequences. the first sequence would do the 4 areas running approximately the same direction then another to do the surface running 90 degrees to that one.

i think i would try surface milling

make all separate machine surfaces and make separate sequences then get codes for whole operation.

profile sequences are not good for 10s or 100s surface machining. You can use finish sequence instead. Just make the angle 89 degrees and you will get what you need.
