speed & feed

[bobbo]

I'm getting ready for my machine to arrive and have been putting my tool info into Aspire and I checked the specs for the WD1 and see that the feed rate max is 160 IPM.

When I calculate the speed/feed rates using chip loads for different material I come up with much higher feed rates (my PC router is rated at 12k - 24k rpm).

What are you doing to figure out feed rates & router speeds?

thanks,
bob

Hi Bob. The WD1 is a great machine, good choice. Feed rates will depend on cutter diam and the depth of cut. I usually cut around 40-50 ipm in 5/8 baltic birch. I'm also using a PC router set at about 20k. using Precise bits and collets. Their diamond-cut 1/8" router bits are great. www.precisbits.com
good luck

Thanks for the response Lee.

I have the same machine setup. Using the chipload charts I should be going much faster but I see that it isn't always so critical. I purchased very small bits from "bits and bits" and some larger bits from "fullerton" they are metal bits and I'm just setting up and playing to get to know the machine and all the software. It's quite a bit of information but everyday it gets easier.

I cut around the same speed as Lee when cutting wood. I'm real technical on how fast I set my feed rate.....If I smell burnt wood I speed it up a bit. The most common bit I use is .125 and I seldom cut more than .1-.15 per pass.

It really depends on material as well. I am using .25" Onsrud bits with a cut depth of .1 and a feed rate of 100ipm in hard maple. Haven't had any problems yet. (Also running a PC 890)

thanks again for your posts... I'm playing around with the speed/feed rates. your input sure helps, with different bits I will be testing them out with new materials etc.
