This paper describes an experimental machining platform that provides metrology during tube turning (orthogonal cutting) for force, global temperature, feed motion, tool wear, and chip formation during continuous feed and modulated tool path, or MTP, turning. MTP is a technique which produces discontinuous chips by superimposing tool oscillations in the tool feed direction on the nominal feed rate to repeatedly interrupt the cutting process. AISI 1026 cold-drawn steel machining experiments are performed and data is presented for: 1) feed motion and modeling; 2) force measurement and modeling; 3) temperature measurement; and 4) chip formation for constant and MTP tool paths. Shear-localized chip formation that begins and ends during a single MTP chip is demonstrated.
