Application tips for tools with a face-finishing cutting edge Radial cutting depth ae max for plane surfaces with tools with a face-finishing cutting edge The right workflow is important to minimize the amount of rest material in the corners of a pocket or step. Our product developers therefore recommend prefinishing after roughing and then finishing the base first before the wall. The NX face-finishing cutter will mill the base and the wall together. Machining of the base is then complete. The wall still has a minimal allowance and is then finished with a finishing tool. Pocket machining When measuring the tool on the machine using a laser, it is very important to specify the correct tool offset. To measure the diameter, a length offset L off of at least h must be specified – FRAISA recommends an L off of 1–2 mm. Machining precision also requires taking a close look at the radius offset. Why? The lowest point of the tool is not at the cutting-edge corner, but a few tenths of a millimeter towards the center. A radial offset R off of c must therefore be specified in the tool table.
