So two years later and still having this issue! wondering if anyone might have some thoughts on the matter.
I have parts to cut out (I made a quick diagram attached) and I'm not sure how to approach the corner sticking out at a diagonal to the wood grain direction. I'm cutting in oak right now which is...
oh i see so you bolt it in from underneath?
The four bolts on the outer perimeter are the ones you use to bolt down on the table?
ok so what I did today was like the images attached.
I placed two parts in one piece of stock and like in my first option mentioned I cut out the profile first on the band saw.
I screwed them down...
I work in wood, typically oak, ash and walnut. I'm wondering how people generally approach a setup for a simple 2d contour in a thick piece of hardwood.
For something like the part in the...
Ah I see that's kind of unfortunate. So does the distance tolerance unit control acceleration or is that something different?
I'm struggling with shapes being overly rounded with constant velocity on, I'm trying to tweak CV "dist tolerance" and "stop cv on angle" settings but its not having any effect,
This happens only...
ok so this has been quite helpful, I'll be in touch with legacy, hopefully with what has come out here I will better suited to explain the problem. Unfortunately we are too far away for the company...
A little while ago I was experiencing what my machine manufacture was calling chatter, essentially the rack wasn't pulled tight enough into the pinion so the gantry was shaky. As per the...
awerby you are right on the money check this image...
So yes they definitely line up with the teeth. I'm not entirely sure what you mean by "preload in the rack has failed", I'm thinking maybe the...
So I'm conventional cutting with a 1/2" end mill with a chipload of 0.0057" at 18000 rpm and a feedrate of 307.8 in/min. I'm doing 0.4" step down using 30% of the cutter width I've been playing...
so I do go in steps no deeper than the width of the tool and I usually do a finishing pass with 0.02" left of material, the piece in the image was done this way actually. Though I'm not sure what...
I am having trouble getting nice clean parts on my CNC, I am machining solid wood and every time the edges come out very bumpy, I tried a variety or cutters, two flute and three flute, I tried...
I'm just going to add to my previous post. In terms of the example you gave @ger21
Using the info given with the mill I was specifically referring too, it's telling me 200 ipm with .0057"...
Thanks for the response, i've been a bit mia here but this is some great info.
So let's forget about the bumpy sidewalls for now, I'm interested what you said about lowering rpm and increasing...
I know there are lots of resources about this online I've been reading loads ever since we got the CNC in the shop but I'd love to talk about my specific situation.
I'm almost exclusively machining...
The spindle is liquid cooled but I gather then that either way it is probably best not to run it under the indicated speed range. Although as I said I do run some drilling operations below that...
I have a somewhat basic question, my machine specs state its speed range to be 12000 to 24000 rpm at max torque. Can I run it lower than 12000? why the low value? I sometimes run it at 5000 rpm for...
ok great thank you!
So I am aware that you are not supposed to drill straight down with a flat end mill, so if i did want to run drilling operations on my cnc can I simply put a regular 1/4" drill bit in my machine? (by...
