Even without CamBam, just using a manual lathe, it is highly unlikely that anyone would choose to machine your part with a 2mm wide square parting tool.
CamBam uses the equivalent of a ball nose tool in standard cnc mode.
It may be possible to specify a tool radius of zero, give it a try and see what the toolpaths look like.
Well..I do.. not with a 2mm wide parting tool, but with a 1 mm parting/grooving tool.
I got a request from a fellow watchmaker to make him some hubs for watchhands, and since everything has to be "Sharp" i need to machine this with a zero radius tool, furthermore, i have to part it off as wel.. why not do that with one and the same tool?, since that saves time for toolchanges.
If you look on YouTube, there are plenty examples of profiling with parting tools..
The Part i have to make is a sort of "Cap" that sits on the minute hand pipe, (0.7 mm diameter), and "Caps off" the secondshand spindle, since that watch will not have a secondshand., total thichkness of the part is 0.9 mm, there is a blind hole in the center, 0.8 mm deep, total diameter is 2.7 mm, , all corners are rounded R0.1, such a part with a grooving tool?. why not?..
I see that CamBam can't work with Parting tools.. I feel the need for an Upgrade...
