METHOD OF ACCELERATED DETERMINATION OF OPTIMUM CUTTING SPEED Russian patent published in 2014 - IPC B23B1/00 

FIELD: process engineering.

SUBSTANCE: this method is characterised by that for tool-part pair at different cutting speeds v defined are tangential cutting forces P_z, fluctuation of tangential cutting forces $${\tilde{P}}_z,$$ fluctuation of cutting speeds $$\tilde{\upsilon }$$ and variable thermal EMF $$\tilde{\epsilon }.$$ Note here that criterion of optimum cutting speed is composed by fluctuation power $$\tilde{N}={\tilde{P}}_z\tilde{\upsilon }$$ or coefficient of fluctuation power application $$K_N=\frac{\tilde{N}}{\overline{N}}=\frac{{\tilde{P}}_z\tilde{\upsilon }}{P_z\upsilon }$$ or analogue of entropy production in heat processes at contact $$\tilde{S}=\frac{{\tilde{P}}_z\tilde{\upsilon }}{\tilde{\epsilon }}.$$ Note also that optimum cutting speed corresponding to minimum wearing of the tool is defined by maximum fluctuation power obtained at the curve of variation in fluctuation power complex, or by break point of fluctuation power use coefficient obtained on the curve of fluctuation power complex use factor variation. Or by minimum parameter of analogue of entropy production in heat processes at contact obtained on the curve of variation in the complex of analogue of entropy production from heat processes at contact.

EFFECT: higher precision of cutting speed selection.
