CNC Mill Modification

This is my first attempt at squaring off one end of an aluminum block. I used an end mill set to the top of the stock and then repeatedly varied the z-depth by a quarter inch during each horizontal sweep of the end mill. This technique resulted in unwanted visible striations. 
   
My second attempt at squaring off the aluminum block resulted in a much smoother machined surface. In this technique I set the end mill to the maximum depth of the stock thickness. I then slowly brought the end mill in towards the stock during each horizontal sweep of the end mill.
