Hey, we have a HAAS VF-1 CNC Milling Machine. I am in a precision machining class and I have a question for you all that I am kind of curious about, and my teacher dosen't know. When we start in the middle of a program, at the tool change, why does it go an get the previouse tool used. Then switch back. For example: If we start at the point within the program wear it retrieves tool 2, It will switch to tool 1, move in a random position(sometimes just a little ways and then back to the tool change position, but its not allways the same position) then change back to tool 2 and continue the program. Why does it do this and is there any rhyme or reason to which point it moves to after it switches to the previous tool.
