its realy easy to understand if you think of Climb milling like this.
The endmill flutes are trying to Climb the part. In turn trying to pull the part closer. More stresses!!!!!! I have tried to climb mill on a bridgport machine, and didnt have the "Slop" out of the table, and it slammed the whole table forward. Manual mills have backlash in them, that is just the way it is. It sounded like a gunshot, and I got "SCHOOLED" on whyit was wrong. Not to mention an ass chewing!
