Pros and cons of climb milling in wood

[Ger21]

e I am trying to say that the effect of climb milling pulls the work towards (or across) the cutter.

The word "towards" is the key here. As you clarified, it does not pull the work towards the bit, but rather along it. I was just trying to say that it doesn't pull into the cutter. If the parts were not clamped down, climb cutting would simply push the work away from the bit, and not throw it out the end of the machine. In order to be thrown, it's position must be constrained in the perpendicular direction, so that the cutter can actually grab the workpiece. If not constrained, it won't be thrown, and monkey B's larger balls would remain intact.

At my day job, we have a large router with two 25HP vacuum pumps to hold sheet goods down. When a part moves a little while climb cutting, it's simply pushed out of the way. If it moves while conventional cutting, the part is pulled into the cutter and typically gets cut in half.

Totally agree....

Thing is, I was Monkey B! the job did not embed itself in my chest just hit me and made me jump. Still bloody hurt but I suppose thats what happens when trying to run 3 machines and answer the phone at the same time..... My mate found it funny though!

Not enough experience with cutting wood but what your saying does make sense, with steel you tend to clamp things down the best that you can so they dont move at all, if they do move then it starts costing you money!
