Study on the correlation of workpiece mechanical properties from compression and cutting tests

Metal cutting tests were conducted on annealed and cold-worked 1100-grade aluminum and 33000-grade leaded brass at a sufficiently slow speed (254 mm/min) that thermal influences on workpiece material properties could be neglected. The mechanical properties of the materials were evaluated in compression using conventional low strain rate test procedures. The material behavior during metal cutting and compression was consistent when the work hardening and strain rate hardening response of these materials was considered. The values of strain rate sensitivity coefficient are in reasonable agreement with literature values. These results support previous data indicating that the material response during metal cutting is consistent with the mechanical behavior determined using conventional material test procedures.
