Ok so I am looking for some serious help on something that makes zero sense to me because it seems to defy logic.
I am cutting a 0.062" material with single flute 0.063" carbide cutter. I am cutting a slot that is 0.063" x 0.250" .
I plunge in without a predrilled hole , rout in x axis then exit. The plunge point looks great and I can put a 0.063" guage pin in very snug and am happy … Now the issue … the rout path is measuring 0.055" and is rough and choppy. The exit is the exact same as the plunge …
How is the world is their such a huge difference between the rout path and the plunge ? How can the rout path measure less than the cutter diameter ?
RPM is 40k and table feed is 30 inches per min ( used this for years without any issues)
I ran this on a different machine and it can our perfect , rout path was 0.063"
I am losing my mind because I cant figure this out … Am I crazy ?
