Tool Gouging.

Hi guys, i am new here just registered recently i got a question.
I recently started working on linuxcnc at my work, im having problems making a hole 15diameter 60mm deep with a tool 12mm in a helix the program says cant make without gouging the workpiece, this was not the first time when we cant make a hole with a tool becuase its to big, but i worked on maho mh700 there i could make this 15mm hole with a 12mm tool whitout a problem,so my question is is there somekind of setup to lower the % of the tool size that linux cnc is letting us work with, or is it a default setup.
Sorsy for my english. And i hope someone can help me.

If you have encoder feedback Linuxcnc has a built-in oscilloscope program you can use to look at the values of any hal pin.

Hi thanks for the answer, the problem is that i dont understand what you mean, and the 2 people who made the transfer from deckel machine to linuxcnc dont know anything either they just grabbed the money and took off with half done job, so we are tryuing to figure out how could we setup some things as it suits us, but i dont even know where to begin, i would gladly accepts some pointers as where should i look up or where can i find that oscilloscope program.

Thank you so far for the reply.

Sorry I think some how my reply to another thread was posted to your question by mistake.

It sounds like a g-code programming error. Are trying to use tool diameter offset? It might not work with one, you may have to program the tool path explicitly.

12 mm milling tool can make a 15 mm hole, post your gcode, we will be able to find the error.
You can use NativeCAM for that.

Hi so here is how i write the code. for a 15mm hole with a 12mm tool, i can make this on maho machines with no problem.
G18 T12 g43 m6
m42
s1600 m3
G0 x0 y10 z0
G1 y-10 f200
G41 x-6.5
G1 z1
G3 x0 z7.5 r6.5
g90.1
g3 x0 z7.5 i0 k0
g3 x0 z7.5 i0 k0
g91.1
g3 x6.5 z1 r6.5
g40
g1 x0 z0
g0 y20

Hope didnt mistype anything the g90.1 and g91.1 im not sure it says so in the manual, but without those with a smaller diamater tool i can make this hole so the 15mm hole i can make whitout a problem with a 7mm atmost that it allows.
We tried the native cam the problem with is, that when the tool finishes it dosent lead out to the center of the hole, but it just goes up at the side of the hole and leaves a mark and that mark is not good for our work this is an example 15mm 0-0.018 hole thats why i need something else with a lead in arc and a lead out arc so it doesent leave a scratch, and i have the same problem with helical program to it says cant make it whitout tool gougin just like for this.
I wrote here cuz i suspect that there is a setup somewhere in linux cnc config that defines what percent of the hole to what tool percent can you make something and i think that value is just to big for or work.
Ps: i use this program for finishing the hole and helical to make with with drilled before so the tool can go down.
Thanks for the reply

Hi,
I had similar Problems. That time i made some subroutines. for circle and Helix. The Syntax and how to call is in the TEST file. G43 and tooldiameter from tooltable is applied. Only used and Tested with metric Units.
