Entering bit into ESTLCAM

Can anyone explain how to enter this bit into ESTLCAM?

If you hover over the last few settings it has a popup of the dimensions it is looking for.

I’ve never figured out how to put those kinds of endmills in. Wonder if @christian-knuell monitors name drops?? :wink:

I thought it was tip angle and tip offset (little math involved but I just saw the formula posted again a week ago or so), is there something I am not seeing?

This was the previous discussion


I’d treat this bit as a shallow angled v-carve with an offset. The ball end is so small, it might as well be a v-carve.

Alternatively, if you know that your DOC is going to be very small (<1mm?) you can treat it as a 0.5mm ball end.

It sure seems like it does when it comes to “real” issues or questions about Estlcam. Was pleasantly surprised at his responsiveness, and one of the reasons why I opted to register his program to support his efforts.

Right, but you can’t put that small of an angle into estlcam, unless I’m missing something. (probably math, I hate math…)

I only started liking math after I found out how much engineer’s make :slight_smile: but it’s a love-hate relationship.

I just tried entering a small angle into the tool list, it didn’t complain… unless I’m missing something as well.

I still hate it but maybe that’s because my boss doesn’t pay me well enough.


The angle might need to be subtracted from 90, I would have to look at the picture.

Bits like that (flat or radius tip) generally mean the given angle is of each side, so for ESTLcam, I would put it as a 10 degree ballnose bit. Since that bit is generally for 3d type carvings, it doesn’t really matter if it’s off by a fraction of a degree, unlike v carving. In the vectric stuff it has options for bits like that.
