Use Caution with Thin-Walled Parts, Too

Similarly, thin-walled parts are also subject to deflection, but because most workpiece materials are nowhere near as rigid as the cutting tools used to machine them, the rules are a bit more stringent. Again, it depends on the part feature and material, but a good rule of thumb is to design walls that are no more than two times the thickness deep, and understand that any wall thinner than around 1/32-inch or so will likely cause problems. As always, check with your machining expert for advice.
