INFLUENCE OF POWER SPENT ON OVERCOMING CUTTING RESISTANCE FORCES ON ELECTRIC MOTOR POWER IN SYSTEM OF AUTOMATIC MACHINE CONTROL WITH NUMERICAL PROGRAMMED CONTROL
Abstract
If a defect unexpectedly arises in the direction of supply while working a «free» curve being distinguished by a arbitrary curvature and small value twisting from the given ones then there will be worsening of cutting process that will lead to surface defects of the machined surface or tool break down. A method of wave analysis has been used for an experimental study of power in specific frequency bands and a minimum cutter damage has been obtained which with power on a drive motor makes it possible to control supply, restoring the condition of cutting. A technical novelty of automatic control method has been proposed according to instantaneous defect by means wave change on a drive motor. The problem of quantitative assessment of machined surface defects has been successfully solved in the paper.
