Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.
CNC Software Inc., Helical Solutions LLC and Makino Inc. — a software developer, cutting tool maker and machine builder, respectively — share the results of their joint R&D project that began with an email introducing a new high-efficiency six-flute endmill with a chipbreaker. This report, which demonstrates how a 40in3 material removal rate was achieved, is a video supplement to the Get With The Program column in the August 2021 issue of Cutting Tool Engineering magazine.
