How fast can you cut?

[Blacknbart]

I am trying to understand how fast a Shopbot machine with a router or spindle attached will cut these simple requests.

How long would it take to cut six 24’’circles out of a:
I know the circle might be sized a little less to accommodate the board in the width and length.

4’ x 8’ sheet of ½ MDO plywood.

4’ x 8’ sheet of 3/4 MDF plywood.

4’ x 8’ sheet of ¼ Acrylic.

4’ x 8’ sheet of 13mm Sintra




How long does it usually take to carve out some text and simple detail artwork out of HDU sign foam. Sizes are sizes:

2’ x 4’

4’ x 8’


Thanks for the help!!

Bart, by the looks of your profile picture, maybe you outta lay off the coffee and slow down a bit.

Sorry, couldn't resist.

the plywood can be cut 3ips though I usually do a cleanup pass so figure about 5 minutes or so.
plastic is a fair amount slower only 1.ips or so. the sintra two passes and say 2ips.

Depending on the tool size, veneered MDF can be cut fairly fast. I will often cut at 6"/sec with a 3/8" compression and 5"/sec with a 5mm compression at 0.375"/per pass. Lots of dust!

Thanks for the helpful information it's a little clearer how fast a router can cut these materials. Providing the machine is set at the correct settings and I'm using the correct bit and compression. So I can I assume if I had a 2' x 4' HDU Sign to carve out it would take no less the 10 minutes to route and carve any letters and or shapes given.

take good care of that good eye...


Depending on how you hold things down, more time can be spent with hold down procedures compared to cutting procedures.
