Do you account for climb cutting in G code?
Hi all,
Do you write/produce your g-code accounting for climb cuts (side cut on a flute mill bit) ? If so how?
I'm trying some simple 3d cutting with multiple levels of toolpaths with finishing cuts on my homebuilt. Using ball end two spiral flute bits, one large to rough out, smaller to finish. For the curious it's purely amateur cutting of half hull models of sailboats in poplar.
The machine is mostly mdf construction so its not hugely stiff (!). I've noticed that when cutting test pieces that there's different loads, vibrations and quality of cut between cutting on the climb ('right') side and the other side of the cutter. Much the same effect as hand routing in woodworking.
I've found that if I code a G-code file to avoid climb cuts I can run faster and get much better results without as much vibration from the toolbit. For me that means cutting one way over the piece.
Anyone else seen that?
Since I'm doing this on the cheap - Rhino / turbocad / Aceconverter / Turbocnc - that means hand modifying the cut file, which is a bit (pardon the pun) tedious to say the least, and of course giving huge opportunity to screw it.... er for error...
Is this something to worry about,? do more serious software packages account for climbcuts when producing a toolpath?
