Re: V-Carve Pro Air Cut

I agree with Adrian, it looks like your Z axis lost some steps in that plunge cut. You must have regular steppers without any position feedback to detect lost steps. That is how my CNC is and I have had certain parts lose position in the Y axis. For my new "homemade" CNC lathe I purchased the Chines...

Re: Toolpath Optimization -Cutting air

Thanks for the suggestions. They definitely work. It would be nice though if the software just did this automatically. I have ran several machinist type cam packages and they all have very tight path optimization to reduce cycle times.

Thanks

Re: V-Carve Pro Air Cut

A simple check you could do to point to the Vcarve software or the CNC controller software setup is to scroll through the G-code and see what Z depth is being called out for around the point you have the jump in position. If the Z depths all look good then I would say it is something to do with the ...

Toolpath Optimization -Cutting air

I had a project that involved v-carving in a grid pattern into a flat board. I drew a horizontal line and a vertical one. I then arrayed them both vertically and horizontally respectively to create my grid. I used "2D profile toolpath" to cut a V, .125 deep. My issue is that it would cut a horizonta...

Re: Rectangular stock for a rotary job

Russell's idea would work if my CNC had the rigidity for that heavy of a cut. I can only do about a 1/8 deep with 50% stepover and 40 FPM. If I go more it chatters like crazy and I end up losing steps on the motor. This is a light machine, not a large industrial one. I am working on a lathe that wil...

Re: Rectangular stock for a rotary job

The problem is that I cant go full depth to the final part size. In the attached picture, the final part is in green. You can see the corners would be almost a .50" deep cut if it went full depth. I can only do about a .125 deep cut with a 50% step over on a .25 dia ball nose carbide router bit. I a...

Re: Rectangular stock for a rotary job

My spindle is not super rigid and I have it pretty much maxed out feed rate and depth wise now, so how I do the cutting doesn't matter. But regardless of the strategy I use to cut it, it wastes a ton of time cutting air. See the attached picture for a better understanding of what I mean. 2/3 of the ...

Rectangular stock for a rotary job

I am running Vcarve Desktop V9.510 and I am using Mach 3 with an A rotary axis. My question is how can I reduce wasted cutting time? I model a 3D part, something like a hatchet handle, in Onshape, and then import it in and 3D rough and finish cut it on my rotary axis. It works just fine. The questio...
