alright will give this a try again.. i am new to cnc lathe and i cant understand for the life of me why when the machine is g2 or g3 the feed rate increses alot compare to a linear movement.. any help would be great.. g0602, g3 controller, fusion software, with masso pp. i can see nothing in the post that would cause it to speed up.. thanx in advance

So,you are asking the lathe to cut an arc of some sort. Let's say your feeding at .01 per revolution. The z axis is moving at .01 per rev and the X axis is barely moving but as it starts to make the arc the X axis is asked to go faster and faster to make the arc as compared to the z axis feed rate. It all looks pretty fast but I don't think either axis is allowed to feed over the programmed rate. What kind of feeds and speeds are you trying to use
