How fast is your router?

[tahustvedt]

I've gradually optimized my router over the last year and half since I built it. I have been running with a rapid speed of 6000 mm/minute velocity and 1500 acceleration for a while now with occasionally losing steps in Y because of a tight backlash ballscrew, thinking that's pretty fast. I even milled aluminium at that speed. Today I tried increasing the voltage from 24 V to 28 V. Now it rapids at 9000 mm/minute (150 mm/s or 354 IPM) velocity with an acceleration of 1700 without ever losing steps where it would lose steps before. I haven't tested a lot of milling yet though, but it was I tried running at 10000 mm/minute (167 mm/s or 393 IPM) with an acceleration of 2000 while planing the table with a 10 mm endmill and that went fine as well, but I turned it down a little to have headroom.

I should say that I have pretty small steppers (1 Nm on Y and 1,23 Nm on X), and ball screws on X and Y. I tried replacing the Y with a larger, stronger Sanyo Denki 1.63 Nm stepper but it only made it lose steps even at lower speeds. I'll save that motor for a higher voltage day.

How fast is fast, exactly? How fast is your router?

My first router run at 150IPM Jog and cutting with 100IPM. (Area 3ft x 4ft)
My second Router run with 100IPM Jog and i cut at 80IPM. (Area :" " ")
My 3rd router all steel 4.5'x 5' run at 750IPM Jog and start cutting at 500IPM..

750 IPM jog. That's pretty fast.

Hi all.
I'm building a CNC wood router machine , but i'm a little stuck with the mechanical things . I am trying to get the acme threaded lead screw and the stepper motors , but i dont know the specifications, which should i get first?? how to choose it's specification???
what should the speed of motion on each axis Be??
My machine is a 3 axis wood router , i'll be drilling MDF wood.
Y-axis : 4 feet long ,25 lbs horizantal movement
X-axis : 2.3 feet ,14 lbs horizantal
Z-axis : .6 feet ,11 lbs vertical

Help please ,thanks.
