    Default advice on the full process

    Howdy!

    I'm looking for advice on tooling for my companies new cnc router.

    we have a 3kw hsd spindle with an er 25 , collects in 1/2 3/8 and 1/4

    I'd like to be able to complete each piece in two cuts/ a single tool change

    a little about the process
    We make airplane propellers out of maple, starting from a blank about 5.5 x 7 x 65 inches, approximately 60 percent of this wood is removed in the production process.

    I will still be removing as much of the bulk material as I can with a bandsaw, but have been mostly looking at the biggest tool I can run for my roughing pass, which I plan to run along the length of the propeller blade, stepping down its height. the final pass I plan to have run up the propeller blade using probably a 1/4 end mill.

    I'm interested in something like an indexable endmill for roughing but I cant find anything like that for wood, just like the idea of replaceable carbide insert, as I wouldnt have to worry about sharping as much for the roughing tool.

    Everything I can find to read only tells me the basic types of bits and other basics, but i'm wondering how you size things to the spindle you have other than trial and error?

    any ideas/suggestions/questions are appreciated!

    Thanks for the input!

    There are a lot of factors involved, including type of tooling, material being cut, workholding,....
    It's also a combination of depth and feedrate. The deeper you cut, the slower you need to go.
