Abstract
For the purpose of investigating variation in cutting temperature between workpiece and tool during approximately orthogonal cutting, following experiments were conducted by tool-workpiece thermocouple method using cutting dynamometer for measuring cutting temperature and cutting force, simultaneously.
Cutting tests were carried out on 4 sorts of pure metals; i.e., aluminum (99.5% purity), copper (99.6%), magnesium (99.9%), and 0.25% carbon steel.
The following results were obtained.
(1) The measured values of cutting temperature in the above metals were arranged in ascending order as follows.
Mg_??_Al<Cu<Fe
(2) It was observed that cutting temperature rase with the increase of cutting speed or feed, but scarcely affected by depth of cut.
(3) Cutting temperatures of the above metals were proportional to their respective shearing stresses.
(4) The rising rates of cutting temperature in the above metals with respect to the increase of cutting speed or feed were arranged in descending order as follows.
With respect to cutting speed Mg>Cu>Al_??_Fe
With respect to feed Mg>Cu>Fe>Al
