4TH axis questions

[Mike@Dive Lab Inc.]

hey guys, I have some parts that need a o-ring groove on the o.d. of the part 1.625" dia. I made a few prototypes a while back out of plastic, now I have to make some out of 316 ss. My problems are when i verify the part it cuts the groove 180. deg off. Instead of coming down and cutting it is going underneath or 180.0 ??

 

Second is the feedrates, there is two spots where the feed almost stops then speeds up and it also seems kinda jerky. I was able to work around the feed problem with plasic but not stainless. The file is on the ftp in the mcx folder file name is 4ax oring groove xlds

hey Matt,they are both set to top, when I post the file it is rotating 180. instead of cutting at A0.0. This is the first time using the 4th ax to do something other than indexing
