Tool temperatures in interrupted metal cutting
Article Abstract:
The tool temperatures in interrupted cutting are investigated. Tool temperature distributions were predicted using the temperature in a semi-infinite rectangular corner heated by a time-varying heat flux with different spatial distributions. These were compared with cutting temperature measurements from interrupted turning tests. Results show that tool temperatures are lower in interrupted cutting than in continuous cutting. Temperatures are affected by the length of heating cycles and cooling time between cycles.

Process-independent force characterization for metal-cutting simulation
Article Abstract:
A unified procedure for simulating cutting forces in various machining processes from a common set of baseline data is shown. In this technique, empirical equations for cutting pressures or forces as a function of the cutting speed, uncut chip thickness and tool normal rake angle are fit to baseline data from end turning, bar turning or fly milling tests. Forces in specific processes are then computed from the empirical equations utilizing geometric transformations.

A review of jet assisted rock cutting
Article Abstract:
The various laboratory and field experiments performed to evaluate the use of high pressure water jets in rock cutting are presented, including its potential use and development. Jet assisted cutting was found to decrease tool forces when water jets are directed within the region of a rock cutting tool. These jets are also effective in cooling the cutting tool and reducing dust, frictional sparking and machine vibration.
