Surfacing Advice

So as I started making larger cuts, I really found a need for a level spoilboard. I picked up a Whiteside #6210 and added it to my tool list using the manufacturer specs. The problem I’m having is that even though it’s a 1" bit, since the flutes are only .125 it’s cutting like a .125 bit. I started to level a 32x24 piece of mdf last night, but quit 5 hours into it when I realized it wasn’t even halfway done. I would assume that changing the flute length would fix the problem, but I figured I would ask around and see what you guys are doing to remedy this issue. Thanks.

Please post a screen grab of your tool definition and your c2d file.

It may help to see:

Here is how my tool is set up. As for the file, I simply made a 32x24 square and created a toolpath to pocket at .010 (one pass). Toolpath time is 688 minutes. It’s only removing 1/16th of material with each pass, which I could have done with any 1/8th endmill.

What do you have the stepover defined as in your file?

Well that’s my problem. I’m not sure what to change the stopover to. So I never changed the stepover, I believe V5 automatically set it to .08.

Sorry but I can 't wrap my head around the …I bought a 1.0 inch (cutter) but added it as a 1/8" cutter…huh? Why would you do this? (Hint: Change it to a 1.0 inch cutter with a 0.5-0.75 step over) PS I sure hope you trammed (Squared) your spindle to the table first.


Half the tool diameter is usually a good starting point.

Here is my custom tool set up for Whiteside and a generic knockoff 1" surfacing bit.
