Hey guys, need some help mazatrol milling is my weak spot and im just trying to do a simple straight keyway on a mazak 350 lathe with a matrix control and with no Y. The endmill is to size and i just want to plunge on center and then move in Z with multiple passes on X. I am using a line center process, I closed both ends of the keyway I keep getting a tool interference alarm. maybe a brief explanation of how line center works would send me in the right direction. I have really good knowledge of mazatrol programming there is something small I must be missing. thanks any help would be appreciated!
