Daym. Coming from the world of metal cutting, that's insane. That's roughly 4-5x the rapid speeds of the mills I've run.

looks like a weird fluted roughing endmill

I know he's talking about milling woods, but I don't think you realize how fast 3500 fucking inches a minute is.

>>1241135
must be some kind of low rigidity high-speed machine, maybe a router?

the heavy components in a CNC slamming around at 3,500 IPM doesn't sound safe

>>1241141
Frankly, the type material is almost immaterial *badump pshh*. Just think about the table sailing around at those speeds, stopping, and changing directions (or the gantry or head or whatever depending on the machine design).

>>1241148
i'm picturing production lines with fast moving conveyor systems. ikea furniture and shit.

3500 inches per minute is 1.5 meters per second.
You don't need to be a machinist to know this is improbable, just the size of machine and power required to accelerate anything up to this speed would be incredible.

>>1241148
maybe it has a long travel and slows down before stopping and starts slowly?

>>1241094
>58 inches/second of table movement

no

OP here so it its the machines that are the limiting factor not the bit itself. In my shop we run a .5 inch compression bit at 1000ipm and thats pretty quick but 3500ipm sounds appealing. I know that rapids on my router run around 3450ipm according to the control box readout, but the machine handles rapids just fine, am I missing something? (im not a grizzled machinist of 35 years so bear with the questions)

Whoopde dick, every salesman has a wonder mill bit that is the dancing be all-do all.

Have the fucker prove it.

and confirmed a real machinist.

No knowledge about routing wood but why would you want a corn cob grind on dusty materials? Isn't it completely useless then?

>>1242052
to help aid in the lung infection, but realistically i think if you put a normal fluted end mill vs food it would probably tear huge chunks of it out rather than cut because its so soft. Atleast thats the only thing i can think of, never worked with wood before

>>1241142
About the average walking speed for a human

Don't know why you'd think it would do that. Normal woodworking tools are bladed/fluted.

Corn cob roughing mills on wood do the same thing as they do on metal; the serrations break up chips, so they can be evacuated more easily. Relevant for hogging out harder woods that tend to form longer chips.

That's the purported rationale, anyway. I've never used them, personally, but it's not like I have a machine powerful enough to warrant them in the first place.

>3500 IPM
Nigga what. Even for wood or super soft material that's fucking wild.
