Customized tool in surfaces

[Donizeti Pinto]

Friends,

 

We tried to use a kind of bull mill (48.5 mm diameter, but with 75 mm nose radius). As there no options to define it as a bull mill we defined this tool as a customized one.

 

With this geometric configuration, we think as we can use bigger "max.stepover" values we´ll save a lot of machining time with good results in terms of smooth machined surfaces.

 

However, Mastercam do not recognize the nose radius nor the tool profile, even it is a customized one. The only available option is to use a corner radius (in customized tool size parameters), that do not work as we need (for instance, the tool do not touch the surface as this one becomes more vertical...)

 

Have anybody got this experience before?

I have not tried to draw this configuration but it is hard to think MC would not see it even as a custom.

 

I have some very odd looking grinds that I had created used and verified in MC and haven't had a problem.

 

When you create your custom do you save it into it's own file and then save it in your tool library, I find this works best for me.

 

Make sure you only draw half the cutter in the XY + quadrant. When you define it choose a file instaed of a level.

copy the original bull mill from the tools folder and rename it what u want, then open that and edit it and save, u should have no problems

 

i have drawn up port tools and custom undercut tools and saved them on levels as well as saving to a file and never had a problem

 

if you continue to have troubles go to the help files relating to custom tools

help also needed

 

just updated to MR1

custom tools backplotted fine in mcamX no sp

but after update to MR1 custom tool defined as a facemill looks like a full radius slotter

 

custom tool file worked fine in both v9.1 and mcamx with not sp's, now not even close

 

any suggestions?

I have the same problem but with cutters showing up as flat disk

[Bruce Caulley]

Same here. Custom tool profiles just look like UFO wreckage in backplot. Works fine in verify.

Been searching forum for my problem, and found this thread - looks like months have past........

Fairly new user, - X,MR1 -

I too, am getting the "UFO Frisbee" look in with custom file tools in backplot - fine in verify. Has there been any progress on this glich?? pretty time consuming to have to verify when a backplot could do most of the time.

[Zoober]

Welp,

after some 'sperimenting, I've come up with a (albeit temporary until fixed) workaround for the UFO.

If I use an external file as my cutter, I ALWAYS get the UFO. If I use a level, I get good backplot tooling. Go figgure!

This IS a bug. (anyone listening?)

Try it yerselves and see if it works for you

[Mark Baker CNC Software]

Yes, there was a bug with custom tools that has been logged and fixed for MR2.

has been? that mean I can get it?

I've got a part with many customs, and would like to backplot/verify.....
