OPTIMISATION OF INTERRUPTED GRINDING PARAMETERS ACCORDING TO THE TEMPERATURE CRITERION

In the paper analytical optimization of discontinuous grinding parameters according to temperature criterion is carried out and on its basis conditions for significant reduction cutting temperature, which consist mainly in increasing number contacts working ledges wheel with fixed cross-section machined workpiece, are determined. It established by calculations that providing 20 may be reduced up 3 times comparison conventional a continuous wheel. This achieved deep interrupted relatively low workpiece speed, as traditionally used multipass not more than 6 an realized only range 50 %. minimum at under equality lengths shoulder notch their reduction. also excess length ledge over leads insignificant increase temperature. reduces wear increases machining capacity without actually The shows obtained theoretical solutions necessary condition ensuring grinding.
