Hi, I am currently trying a new post for our Emco E25 Mill-Turn machine.
So hopefully this will make sense to someone;
I have a problem with the feeds. When I output I get a feed value on each movement and it is a random value. This produces a erratic cutter path and a poor finish. This doesn't seem right to me but our CAM supplier, says this is the correct output as," SolidCAM is converting constant linear feed-rate into a rotary feed-rate for the rotating axis. This will slow or increase as necessary when the part rotates thus keeping a constant surface feed on the irregular shape."
Is there a way I can modify the post to to turn off the constant linear feed fore the roughing and finish passes? I have semicolon out all the feed values and entered a more realistic feed rate this works well. Our supplier has also told me I should have the " interpolation by tolerance" box ticked to shorten the line length as the output without this does not produce the correct tool path. (I'm not convinced about this one either).
