METHOD FOR STUDY OF CUTTING TOOL DEFORMATION IN PROCESS OF CUTTING Russian patent published in 2011 - IPC G01B11/16 

FIELD: physics.

SUBSTANCE: method for study of cutter tool deformation in the process of cutting is as follows: one preliminarily applies crosswise close-pitched grooves on the blank surface while the lateral surface of the tool cutting end material is polished. Then one illuminates the polished lateral tool surface with a flux of coherent monochromatic radiation, forms an interference pattern and performs continuous registration of interference patterns changes. Then one implements the process of cutting in the modes concerned; determines power load deformation component by way of recalculation of differences between series of interference fringes having passed through varied cross-sections in interference patterns obtained in the process of cutting immediately before the crosswise groove and at the moment of the tool cutting edge being inside the groove.

EFFECT: performance of high-precision inertia-free contactless measurements of changes in the deformation field of the tool cutting edge material as a result of power loads under non-stationary cutting conditions, provision for an opportunity to calculate dynamics of the tool cutting edge strain and deformation condition and strength under such conditions.
