THE INFLUENCE OF COOLING CONDUCTIVITY ON THE CHANGE OF TEMPERATURE GRADIENT IN THE PCBN TOOL
Виконаний модельний аналіз впливу теплопровідності захисного покриття TiAlN на градієнт температури в інструменті, оснащеному надтвердим композитом «киборит», при обробці загартованої сталі. Встановлено, що захисне покриття має суттєвий вплив на градієнт температури в різальному інструменті з надтвердого композиту ПКНБ в тому випадку, коли коефіцієнт ...
