Hey all, so I'm machining some 4340 using a 5/8" endmill 5 fl variable pitch taking 1.500" doc and have tried rdoc of .03-.125" and multiple combinations of different feeds and speeds all with the same results. It is running around the entire part and machining two 1.25" slots through the part as well all using an apative tool path. It cuts like butter everywhere except when cutting the back of the part moving in the X axis it sounds like someone is murdering a small child. I've checked the backlash which is as close to 0 as it's going to be in all directions. I'm using a milling chuck and not trying to run at any crazy feeds or speeds so something is telling me there is something loose in my machine. If anyone has and things to check it'd be greatly appreciated!
