Hello,
Is it possible in Visualmill to have a slower feed rate when the cutter is cutting 100% of its diameter?. For example, lets say you are milling a rectangular pocket, the first cut will have the cutter cutting its full diameter, the next cuts will be cutting whatever stepover you specified in the program. Is it possible to tell Visual Mill to have a slower feed rate when thi fist cut is being made, and then pump the feed rate up on the next cuts?
Ive seen some other CAM programs do this
Best Regards

Fernando,

This would be an extremely useful feature... sure would beat sitting at the feed rate overide when ramping into a full diameter cut.

The only way I know of is to create a separate MOP for the first pass with its own feed rate... definately a pain in the ?ss

Hopefully someone more knowledgable will chime in with a better approach.

regards Gary

This takes the g-code from VisualMill or other CAM system and then applies speed optimizations.

I am pretty sure it's not "hobby priced".

I use a work around the same as the Dr ^^
I find that I quite often use 2 MOPs where theoretically 1 should work.
I find the 2D advanced MOPs useless and always make 2 of my own.

Hi!
I checked on optipath by vericut, its not hobby priced (but i guess neither is visual mill) its between $4K and $8K, from what ive heard. And im pretty sure it is not so easy to use. I was inclined to visual mill from all the CAM options because its short learning curve.
I just cant beleive that CAM packages that go for thousands of dollars, dont have this option.
It would sure beat by far, standing besides the feed override for a 10 hour program. Deskproto has an option that slows the feedrate in heavy cuts. But is not nearly as functional as Visual Mill, from my point of view.

What is the procedure of making 2 machine operations instead of just one?
Is it the following?:
If you are trying to machine a tapered island, instead of just making an horizontal roughing and then a parallel finishing, you would to a profile cut along the outline of the base leaving some stock(this procedure with a slow feedrate), and then horizontal roughing (with a faster feed rate) and then the parallel finishing?
Am I following you correctly?
Regards
Fernando

Why not manually edit the code, and just add "F50.0" or however fast you want to the end on the initial, full-diameter cut? I know this is not the easiest fix, but it is what I use when making keyholes in wood. There is no need to move slow after the keyhole is already cut, and I just need to back the tool out.

well this is complicated when cutting a 3d part, with lots of places where it engages 100%, plus codes above 200,000 lines, its not that simple.
Thanks for the suggestion

Did you bring this to the attention of the guys over at VisualMill? I'm sure they would like to hear those kind of feedbacks!
As for the problem, I have to agree!! That is definitely something that should be Implemented in Software that is that high priced.
