I have a part that the width (Y-Axis) is .750" and I am putting a slot through it that is .755" wide and depth of .750". Material is 304SS and I am taking a .02" cut per pass with a carbide 1/2" 4FL end mill. The first operation is 5 hours and 36mins. I have two more operations which is even longer. I need to drastically speed this up. What feeds and speeds should I run. Currently running at 918rpm 1.8 feed. I have a HAAS VM 2 and max rpm is 12,000. This is our first time having high speed machining and we just are not sure about feeds and speeds to run. I can not get it to program the tool path I want. It just runs straight back and forth through the part instead of doing the high speed circles pecking at the part. I will post a picture to show you what tool path it is producing.
