I have an ABB IRB 6400R on a 14m slide. It uses an s4c controller. I am trying to mill out slots in thin material but I am finding when the robot accelerates and decelerates it seems to be causing a jolting action cause the slots to be disfigured. When in between the start and the end of the cut it is perfect. 

I was wondering is there anything I can use to change the acceleration and deceleration when cutting? Is there a command I can use or would I have to change it within system parameters?

The instruction that you are looking for is called AccSet, it has two parameters, from 1 - 100 in percent.  In my opinion you get better results with the second.

How do I use this? Do I just set it once at the start of the program or before each move instruction?

You need to put the instruction before you want it to take effect.  Know that it will remain in effect until you reset it--AccSet,100,100;  Or, if PP to Main, new program loaded, restart controller and such.
