new drag knife cutter

[woodman08]

I setup the new drag knife from donektools.com ,its 1/2 shank goes in the router
collet or spindle takes standard box knife blades this model the D2 will cut up to
1/4 materials.
Programmed the cut using aspire
and calling it a 1/64 end mill and ramping it in 1 inch for the cut
You can contact Sean Martin (smartin@donek.com) for more info or me
I am anxious to try more materials like vinyl or veneers or a heavier plastic

the drag knife design is interesting as it has to be balanced in such a way that when the router/spindle moves the blade follows or it could snap off the end.
Because the blade is out aout 1/4 one should be able to cut 1/4 material.
There are probably some tricks in aspire to help this cutter do a better job
I would like to find some vinyl to cut letters from as cutiing vinyl with a laser produces bad gases,also cutting veneer will be interesting

Hi Stan,

I've been looking at these, too. Pretty cool setup. Do you have his Excel spreadsheet for adding corner actions to your toolpaths? The corner action spreadsheet seems to be necessary for lettering, or any sharp corners.

If you've tried it, how does it work?

Thanks!

just use the inlay feature much easier.

this is the d2 drag knife which can cut up to .25 in material,it looks
like a simple concept but its not take it from me ,there is a lot of
programming thought went into the use of it ,as you need to run a macro
in excel to make some changes to your toolpath in order for the knife to
have its proper orientation
