Re: Chatter - I am lost for ideas please help
hello be sure that you are using the same insert as before
if you could use in the past "1000rpm .12mm/rev dcmt insert finisher. 0.5mm depth of cut", but now it does not work anymore, at least be sure that it is the same insert
it may be the material ... to be sure that it is not the material, you have to use same inserts as before, from the same insert lot, and compare axis loads, or, if possible, compare load diagrams
same insert may not be always crafted with same characteristics, thus is possible that a new lot of inserts is better/worse than a lot from 3 months ago
have had various degrees of success over the years
maybe this is not ok; maybe it means that, so far, the setup was not stabilized ... as a consequence, it could go better or worse anytime, without a sign
all i can do, is recomand you kyocera dcmt 11t304mq ca6525 (r0.4), or 11t302mq (r0.2) / kindly
