Typically, FacFox can hold a machining tolerance of +\/- 0.005 in. (0.13mm). Part features are recommended to be thicker than 0.020 in. (0.51mm) in all regions and a nominal part thickness above 0.040 in. (1.02mm) is required. Maximum depth that can be milled is 2 in. (50.8mm) from either side of the part. For specific milling dimensions by material, see maximum part extents for machining.<\/p>\n
