Rest Roughing
The Rest roughing strategy determines the areas where material remains unmachined after the previous machining operations ( the " rest " of material) and generates a tool path for the machining of these area . The tool path is generated in the contour roughing ( see topic 2.2 ) manner. Rest roughing operation uses a tool of smaller diameter than that used in previous roughing operations
The following image illustrates the hatch roughing tool path performed with a End mill of dis.20 .
