milling diagram (climb/conv)

[SE18]

I was looking for a diagram to hang up on my wall to remind me which way to feed the work/end mill so I avoid climbing (my particular mill is not really up to climbing).

I came across this diagram (attached), from this site:
http://www.cnccookbook.com/CCCNCMillFeedsSpeedsClimbConventional.htm

The reason I like this diagram is it gives an overall perspective, all the way around the work piece instead of just a closeup of the cutter head and the work, which is more confusing.

I assume the blue straight arrows indicate the direction the work should be moving. If that is correct, then looks to me that the quick rule of thumb is when milling the outside edge of a piece of work, the work should always move in a clockwise direction for conventional milling.

Did I get that right?

That diagram is somewhat confusing. The arrows are reffering to the direction of the work, or should be.

The surface of the cutter thats touching the work should be moving in opposite directions to each other for conventional milling, and in the same direction for climb milling.

So should it be counterclockwise for conventional?

I dont known Marcel ., picture said it all' come in like a bucket on a loader as it spins you are skinning: go the other side, then, you are climbing up a hilll.
did I say this corretly? Sloting you are doing both . put the cutter down both sides then slot it , got it ..... ex use me another bad day (the kid)

samue..........................

Its a little embarrassing but my simple rule of thumb is to "bang heads" when conventional edge milling. It reminds me to move the edge of whatever work surface I am cutting in the direction that is opposite to the direction the cutter is rotating. At the point of contact, they "bang heads". Stupid, I know, but it never fails me.

You guys can ponder it all day....I know the difference and I ain't showing you! :-D

My rule is even easier: "Don't Push"

I'm just curious why a table is needed. If the mill cutter is turning like a tire of a car driving over the work you are climb milling.

If you are running a heavy duty milling machine you can mill in either direction. When I was using a horizontal milling machine I milled in both directions. It depends on the material and the age of the milling machine. Older machines sometimes have a lot of slack in their feed gears. If you climb mill snug the table clamps so it doesn't jerk on you.

Good luck

i cut into the piece to remove material then reverse direction to finish cut
